The UK left the EU on 31 January 2020 and entered an 11-month transition phase during which previous arrangements largely applied. On 30 December 2020, the UK and the EU signed the Trade and Cooperation Agreement (TCA) (see also), which set out the details of the post-Brexit trading arrangements between the UK and the EU after the ending of the transition period on 31 December 2020. The new arrangements have been implemented in stages so as to minimise disruption.

A major change was implemented on 1 January 2022, when full customs controls came into effect on imports into the UK from the EU. Later in the year a range of safety and security measures will be introduced, such as physical checks on live animals.

Not surprisingly, the anniversary of the TCA has been marked by many articles on Brexit: assessing its effects so far and looking into the future. Most of the articles see Brexit as having imposed net costs on the UK and the EU. They reflect the views of economists generally. As the first FT article linked below states, “The debate among economists on Brexit has rarely been about whether there would be a hit to growth and living standards, but rather how big a hit”.

The trade and GDP costs of Brexit

The Office for Budget Responsibility in October 2021 attempted to measure these costs in terms of the loss in trade and GDP. In October 2021, it stated:

Since our first post-EU referendum Economic and Fiscal Outlook in November 2016, our forecasts have assumed that total UK imports and exports will eventually both be 15 per cent lower than had we stayed in the EU. This reduction in trade intensity drives the 4 per cent reduction in long-run potential productivity we assume will eventually result from our departure from the EU.
 
…the evidence so far suggests that both import and export intensity have been reduced by Brexit, with developments still consistent with our initial assumption of a 15 per cent reduction in each.

This analysis is supported by evidence from John Springford, deputy director of the Centre for European Reform think-tank. He compares the UK’s actual performance with a ‘doppelgänger’ UK, which is an imaginary UK that has not left the EU. The doppelgänger used “is a subset of countries selected from a larger group of 22 advanced economies by an algorithm. The algorithm finds the countries that, when combined, create a doppelgänger UK that has the smallest possible deviation from the real UK data until December 2019, before the pandemic struck.” According to Springford, the shortfall in trade in October 2021 was 15.7 per cent – very much in line with the OBR’s forecasts.

Explanations of the costs

Why, then, have have been and will continue to be net economic costs from Brexit?

The main reason is that the UK has moved from being in the EU Single Market, a system of virtually friction-free trade and factor movements, to a trade agreement (the TCA) which, while being tariff and quota free for goods produced in the UK and the EU, involves considerable frictions. These frictions include greatly increased paperwork, which adds to the cost of trade. This has affected small businesses particularly, for whom the increased administrative costs generally represent a larger proportion of total costs than for large businesses.

Although EU tariffs are not imposed on goods wholly originating in the UK, they are imposed on many goods that are not. Under ‘rules of origin’ regulations, an item can only count as a British good if sufficient value or weight is added. If insufficient value is added, then customs charges are imposed. Similar rules apply from 1 January 2022 on goods imported into the Great Britain from the EU which are only partially made in the EU. The issue of rules of origin was examined in the blog A free-trade deal? Not really. Goods being moved between Great Britain and the EU are checked at ports and can only be released into the market if they have a valid customs declaration and have received customs clearance. This involves considerable paperwork for businesses. As the article below from Internet Retailing states:

UK and EU importers need to be able to state the origin of the goods they trade between the UK and EU. For some goods, exporters need to hold supplier declarations to show where they were made and where materials came from. From January 1, those issuing statements of origin for goods exported to the EU will need to hold the supplier declarations at the time that they export their goods, whereas up till now the those declarations could be supplied later.

Brexit has had considerable effects on the labour market. Many EU citizens returned to their home countries both before and after Brexit, creating labour shortages in many sectors. Also, it has become more difficult for UK citizens to work in the EU, with work permits required in most cases. This has had a major effect on some UK workers. For example, British touring musicians and performers find it difficult to tour, given the lack of an EU-wide visa waiver, ‘cabotage’ rules that ban large UK tour vehicles from making more than two stops before returning to the UK and new paperwork needed to take certain musical instruments into the EU.

Another issue concerns investment. Will greater restrictions in trade between the EU and the UK reduce inward investment to the UK, with international companies preferring to locate factories producing for Europe in the EU rather than the UK as the EU market is bigger than the UK market? So far, fears have not been realised as inward investment has held up well, partly because of the rapid bounce-back from the pandemic and the successful roll-out of the vaccine. Nevertheless, the UK’s dominance as a recipient of inward investment to Europe has been replaced by a three-way dominance of the UK, France and Germany, with France being the biggest recipient of the three in 2019 and 2020. It will be some years before the extent to which Brexit has damaged inward investment to the UK, if at all, becomes clear.

The TCA applies to goods, not services. One of the major concerns has been the implications of Brexit for financial services and the City of London. Before Brexit, financial institutions based in the UK had ‘passporting rights’. These allowed them to offer financial services across EU borders and to set up branches in EU countries easily. With the ending of the transition period in December 2020, these passporting rights have ceased. The EU has granted temporary ‘equivalence’ to such institutions until June 2022, but then it comes to an end and there is no prospect of deal on financial services in the near future. Indeed, the EU is actively trying to encourage more financial activity to move from the UK to the EU. Several financial institutions have already relocated all or part of their business from London to the EU.

The articles below examine these costs and many give examples of specific firms and how Brexit has impacted on them. As you will see, there are quite a lot of articles and you might just want to select a few. Or if this blog is being used for classes, the articles could be assigned to different students and used as the basis for discussion.

The future

Whilst the additional costs in terms of trade restrictions and paperwork are clear, it is too soon to know how well firms will be able to overcome them. Many of those who support Brexit argue that the UK now has freedom to impose lighter UK regulations on firms and that this could encourage economic growth. Other supporters of Brexit, however, argue that Brexit gives the UK government the opportunity to impose tougher environmental, safety and employment protection regulations. Again, it is too soon to know what direction the current and future governments will move.

Then there is the question of trade deals with non-EU countries. How many will there be? When will they be signed? What will their terms be? So far, the deals signed have largely been just a roll-over of the deals the UK previously had with these countries as a member of the EU. The one exception is the deal with Australia. But the gains from that are tiny – an estimated gain of between 0.02 and 0.08 per cent of GDP from 2035 (compared with the estimated 4 per cent loss from leaving the EU’s Single Market). Also there are fears by the UK agricultural sector that cheaper food from Australia, produced under lower standards, could undercut UK farmers, especially after the end of a 15-year transitional period. So far, a trade deal with the USA seems a long way off.

Then there are uncertainties about the Northern Ireland Protocol, under which there is an effective border between Great Britain and the EU down the Irish Sea, with free trade across the Northern Ireland–Republic of Ireland border. Will it be rewritten? Will the UK renege on its treaty commitments to impose checks on goods flowing between Northern Ireland and Great Britain?

Difficulties with the Northern Ireland Protocol, highlight another uncertainty and that is the political relationships between the UK and the EU, which have come under considerable strain with various post-Brexit disputes. Could these difficulties damage trade further and, if so, by how much?

What is clear is that there is considerable uncertainty about the future, a future that for some time is likely to be affected by the pandemic and its aftermath in both the UK and the EU. As the OBR states:

It is too early to reach definitive conclusions because:

  • The terms of the TCA are yet to be implemented in full, meaning trade barriers will rise further as more of the deal comes into force. For example, the introduction of full checks on UK imports has recently been delayed until 2022.
  • The full effect of the referendum outcome and higher trade barriers will probably take several years to come through, with businesses needing considerable time to adjust.
  • The pandemic has delivered a large shock to UK and global trade volumes over the past 18 months, making it difficult to disentangle the separate effect of leaving the EU.
  • Finally, trade data tend to be relatively volatile and are revised frequently, rendering any initial conclusions subject to change as the data are revised.

Shipping and supply chains generally have experienced major problems in 2021. The global pandemic disrupted the flow of trade, and the bounce-back in the summer of 2021 saw supply chains stretched as staff shortages and physical capacity limits hit the transport of freight. Ships were held up at ports waiting for unloading and onward transportation. The just-in-time methods of delivery and stock holding were put under considerable strain.

The problems were compounded by the blockage of the Suez canal in March 2021. As the blog, JIT or Illegit stated “When the large container ship, the Ever Given, en route from Malaysia to Felixtowe, was wedged in the Suez canal for six days in March this year, the blockage caused shipping to be backed up. By day six, 367 container ships were waiting to transit the canal. The disruption to supply cost some £730m.”

Another major event in 2021 was the Glasgow COP26 climate conference and the growing willingness of countries to commit to decarbonising their economies. But whereas electricity can be generated from renewable sources, and factories and land transport, such as cars, vans and trains, can run on electricity, it is not so easy to decarbonise shipping, especially for long journeys. They cannot plug in to the grid or draw down from overhead cables. They have to carry their own fuel sources with them.

So, have the pandemic and the Ever Given incident exposed weaknesses in the global supply chain and in shipping in particular? And, if so, in what ways is shipping likely to adapt? And will the pressure to decarbonise lead to a radical rethinking of shipping and long-distance trade?

These are some of the issues considered in the podcast linked below. In it, “Shipping strategist Mark Williams tells Helen Lewis how examining the challenge of decarbonising shipping reveals a future which looks radically different to today, in a world where population, oil extraction and economic growth have all peaked, and trade is transformed”.

During the pandemic, millions of people’s wages in the UK were paid by the government to prevent the closure of businesses and a surge in unemployment. The furlough scheme officially came to an end in September 2021. However, with the spread of the Omicron variant and the fear of further restrictions being put in place, there has been a call by many to re-introduce the furlough scheme.

The furlough scheme

The furlough scheme began when the government brought in, what was officially called the Coronavirus Job Retention Scheme (CJRS) in early 2020. This was when the pandemic first forced businesses across the country to close. The scheme worked by paying part of employees’ wages, preventing the need for businesses to make their staff redundant, therefore avoiding a rapid rise in unemployment along with the associated costs. It also avoided the financial and emotional costs of firing and then rehiring workers post pandemic. Under the scheme, furloughed workers received 80% of their wages, up to £2500 a month, if they couldn’t work because of the impact of coronavirus. Employees were able to maintain the security of employment and the payments helped furloughed workers pay their bills.

The scheme saw billions of pounds spent paying the wages of employees whose firms were forced to close temporarily. It could be argued that the expense of the scheme was a huge disadvantage. However, the alternative would have been for the government to pay unemployment-related benefits. Despite the furlough scheme being deemed necessary, it was not without its drawbacks for the structure of businesses. Rather than businesses adapting to changes in the economy and consumer demands, they could decide to claim the money and avoid the need to restructure. There was also concern about the length of the furlough scheme and the ability of businesses to bounce back post-pandemic.

Since the start of the scheme, the specifics of what was paid and who received it changed over time, especially once the economy started opening again. Initial steps were made to allow part-time return to work and the scheme started to wind down over the summer of 2021, with the government covering less of the wages and businesses covering more. From July, employers had to provide 10% of the wages of their furloughed staff, with the government paying the rest. This then increased to 20% in August with the CJRS coming to a complete end on 30 September 2021. At this point, there were around 1.6 million employees still receiving payment from the scheme.

Impact on Employment

With the end to the furlough scheme in September 2021, there were concerns that this would lead to a large number of redundancies. However, data indicate that has not happened and there is a record number of job vacancies. Official figures show that UK employment rose in October, confirming the strength of the labour market. The Office for National Statistics stated that the employment rate rose to 75.5% in the three months to October, up 0.2 percentage points on the previous quarter. This is believed to be driven by a rise in part-time work, which had dropped sharply during the pandemic. However, it is important to note that the strength in these numbers was prior to the emergence of the Omicron variant.

Omicron

In November, the government had ruled out once again bankrolling people’s wages at enormous expense. However, the Chancellor is now under pressure to respond to the latest announcements around the ever-changing landscape of the pandemic. The fast-spreading mutation of the Covid-19 virus, Omicron, is posing a fresh threat to the economy.

On the 8 December, the Prime Minister announced new ‘Plan B’ Covid rules for England. As part of these new rules to limit the spread of Omicron, people are being asked to work from home again if possible and face masks are compulsory in most public places. Covid passes or a negative Covid test result are also needed to get into nightclubs and large venues.

Scotland and Wales have brought in further restrictions. Scotland’s First Minister, Nicola Sturgeon, has asked people to limit socialising to three households at a time in the run-up to Christmas. Shops and hospitality venues in Scotland must bring back physical distancing and screens. In Wales, nightclubs will close after 26 December and social distancing will be reintroduced in shops.

Although the hospitality industry and retail sector remain open, they are facing a slump in trade thanks to the new restrictions and worries among the general public. With the work-from-home guidance and advice from health officials that people should limit their social interactions, pubs and restaurants have seen widespread cancellations in the run-up to Christmas. Trade is suffering and these mass cancellations come at a time when these sectors were hoping for bumper trade after a dismal last couple of years.

In light of these concerns, ministers are now being urged to guarantee support in case businesses have to shut. Despite the indication that it would be highly unlikely that the UK would experience a full return to the restrictions seen at previous stages of the crisis, the International Monetary Fund has stated that the UK government should be drawing up contingency plans. The IMF has called for a mini-furlough scheme in the event that the Omicron variant forces the government to close parts of the economy. The idea is that the mini-furlough scheme would see a limited version of the multi-billion-pound job subsidy scheme being rolled out if firms are forced to close.

There are strong calls for there to be targeted support, which this mini-furlough scheme could offer. The Resolution Foundation argued in mid-December that a furlough scheme tied solely to the hospitality industry would help prevent job loses in an industry that is currently suffering once again. It calculated that the cost of a hospitality-only furlough scheme would be £1.4 billion a month if it were pitched at the original level of 80% of wage support. If a January to March sector-specific scheme were to be introduced it is estimated to cost around £5 billion, a small cost in comparison to £46 billion spent on furlough so far.

Inflation

Any reintroduction of a furlough scheme would be a jolt for the government. This would mean a return to the 2020-style arguments around protecting livelihoods and businesses, a contrast to the recent messaging from the Treasury of restoring public finances. There is also concern about how this will all impact on current growth predictions and inflation concerns. The IMF expects the growth of the UK economy to be 6.8% in 2021 and 5% in 2022. However, the drawback from this is that the recovery would also be accompanied by rising inflation. It has been suggested, therefore, that interest rate increases from the Bank of England would be needed to keep inflation under control, while at the same time being not so great as to kill off growth.

It was widely expected that the Bank of England would again put off a rate hike in order to wait to see the economic impact of Plan B restrictions. However, on Thursday 16 December, interest rates were raised for the first time in more than three years. Despite the fears that Omicron could slow the economy by causing people to spend less, Bank Rate was raised from 0.1% to 0.25% . This came in the wake of data showing prices climbing at the fastest pace for 10 years.

Next Steps?

Government finances would take another huge hit if the furlough scheme were revived. But a version of such a scheme is likely to be necessary to avert an unemployment crisis and the attendant costs.

However, in resisting further measures, the government has argued that it has already acted early to help control the virus’s spread by rapidly rolling out booster jabs, while avoiding unduly damaging economic and social restrictions.

The government also argues that some of the measures from the total £400 billion Covid support package since the start of the pandemic will continue to help businesses into Spring 2022. Such measures include government-backed loans for small- and medium-sized businesses until June 2022, a reduction in VAT from 20% to 12.5% until March 2022 and business rates relief for eligible retail, hospitality, and leisure businesses until March 2022. Talks are ongoing with hospitality and and other business organisations directly affected by Covid restrictions.

The British Chambers of Commerce has argued that current measures are not enough and has called for VAT on hospitality and tourism to be cut back to its emergency rate of 5% and for the 100% business rates relief for retailers to return. The CBI has also called for any unspent local authority grants to be spent now to help affected firms and that further help, including business rates relief, should be on the table if restrictions continue after the government’s 5 January review date. The IMF said that with strong policy support, the economy had proved resilient, but it stressed that a return of some of the measures that prevented mass unemployment and large-scale business failures might soon be needed.

Conclusion

Infections caused by the new Omicron variant are rising rapidly, doubling every two to three days. It is expected to become the dominant variant in the UK soon with health officials warning it may be the most significant threat since the start of the pandemic. However, it is not yet known what the full extent of the impact of this new variant on the NHS will be, leaving the severity of future restrictions uncertain.

But what is evident is that the course of the pandemic has changed and there is a growing case for the government to start planning for new support packages. Although a reintroduction of the furlough scheme was hoped not to be needed on the path out of the pandemic, a short detour may be required in the form of a mini-furlough scheme. The size and reach of any support put in place will depend upon any further restrictions on economic activity.

The Climate Change Pact agreed by leaders at the end of COP26 in Glasgow went further than many pessimists had forecast, but not far enough to meet the goal of keeping global warming to 1.5°C above pre-industrial levels. The Pact states that:

limiting global warming to 1.5°C requires rapid, deep and sustained reductions in global greenhouse gas emissions, including reducing global carbon dioxide emissions by 45 per cent by 2030 relative to the 2010 level and to net zero around mid-century, as well as deep reductions in other greenhouse gases.

So how far would the commitments made in Glasgow restrict global warming and what actions need to be put in place to meet these commitments?

Short-term commitments and long-term goals

According to Climate Action Tracker, the short-term commitments to action that countries set out would cause global warming of 2.4°C by the end of the century, the effects of which would be calamitous in terms of rising sea levels and extreme weather.

However, long-term commitments to goals, as opposed to specific actions, if turned into specific actions to meet the goals would restrict warming to around 1.8°C by the end of the century. These long-term goals include reaching net zero emissions by certain dates. For the majority of the 136 countries agreeing to reach net zero, the date they set was 2050, but for some developing countries, it was later. China, Brazil, Indonesia, Russia, Nigeria, Sri Lanka and Saudi Arabia, for example, set a date of 2060 and India of 2070. Some countries set an earlier target and others, such as Benin, Bhutan, Cambodia, Guyana, Liberia and Madagascar, claimed they had already reached zero net emissions.

Despite these target dates, Climate Action Tracker argues that only 6 per cent of countries pledging net zero have robust policies in place to meet the targets. The problem is that actions are required by firms and individuals. They must cut their direct emissions and reduce the consumption of products whose production involved emissions.

Governments can incentivise individuals and firms through emissions and product taxes, through carbon pricing, through cap-and-trade schemes, through subsidies on green investment, production and consumption, through legal limits on emissions, through trying to change behaviour by education campaigns, and so on. In each case, the extent to which individuals and firms will respond is hard to predict. People may want to reduce global warming and yet be reluctant to change their own behaviour, seeing themselves as too insignificant to make any difference and blaming big business, governments or rich individuals. It is important, therefore, for governments to get incentive mechanisms right to achieve the stated targets.

Let us turn to some specific targets specified in the Climate Change Pact.

Phasing out fossil fuel subsidies

Paragraph 20 of the Climate Change Pact

Calls upon Parties to accelerate … efforts towards the … phase-out of inefficient fossil fuel subsidies, while providing targeted support to the poorest and most vulnerable in line with national circumstances and recognizing the need for support towards a just transition.

Production subsidies include tax breaks or direct payments that reduce the cost of producing coal, oil or gas. Consumption subsidies cut fuel prices for the end user, such as by fixing the price at the petrol pump below the market rate. They are often justified as a way of making energy cheaper for poorer people. In fact, they provide a bigger benefit to wealthier people, who are larger users of energy. A more efficient way of helping the poor would be through benefits or general tax relief. Removing consumption subsidies in 32 countries alone would, according to International Institute for Sustainable Development, cut greenhouse gas emission by an average of 6 per cent by 2025.

The chart shows the 15 countries providing the largest amount of support to fossil fuel industries in 2020 (in 2021 prices). The bars are in billions of dollars and the percentage of GDP is also given for each country. Subsidies include both production and consumption subsidies. (Click here for a PowerPoint of the chart.) In addition to the direct subsidies shown in the chart, there are the indirect costs of subsidies, including pollution, environmental destruction and the impact on the climate. According to the IMF, these amounted to $5.4 trillion in 2020.

But getting countries to agree on a path to cutting subsidies, when conditions vary enormously from one country to another, proved very difficult.

The first draft of the conference agreement called for countries to ‘to accelerate the phasing-out of coal and subsidies for fossil fuels’. But, after objections from major coal producing countries, such as China, India and Australia, this was weakened to calling on countries to accelerate the shift to clean energy systems ‘by scaling up the deployment of clean power generation and energy efficiency measures, including accelerating efforts towards the phasedown of unabated coal power and phase-out of inefficient fossil fuel subsidies’. (‘Unabated’ coal power refers to power generation with no carbon capture.) Changing ‘phasing-out’ to ‘the phasedown’ caused consternation among many delegates who saw this as a substantial weakening of the drive to end the use of coal.

Another problem is in defining ‘inefficient’ subsidies. Countries are likely to define them in a way that suits them.

The key question was the extent to which countries would actually adopt such measures and what the details would be. Would they be strong enough? This remained to be seen.

As an article in the journal, Nature, points out:

There are three main barriers to removing production subsidies … First, fossil-fuel companies are powerful political groups. Second, there are legitimate concerns about job losses in communities that have few alternative employment options. And third, people often worry that rising energy prices might depress economic growth or trigger inflation.

The other question with the phasing out of subsidies is how and how much would there be ‘targeted support to the poorest and most vulnerable in line with national circumstances’.

Financial support for developing countries

Transitioning to a low-carbon economy and investing in measures to protect people from rising sea levels, floods, droughts, fires, etc. costs money. With many developing countries facing serious financial problems, especially in the light of measures to support their economies and healthcare systems to mitigate the effects of COVID-19, support is needed from the developed world.

In the COP21 Paris Agreement in 2015, developed countries pledged $100 billion by 2020 to support mitigation of and adaptation to the effects of climate change by developing countries. But the target was not reached. The COP26 Pact urged ‘developed country Parties to fully deliver on the $100 billion goal urgently and through to 2025’. It also emphasised the importance of transparency in the implementation of their pledges. The proposal was also discussed to set up a trillion dollar per year fund from 2025, but no agreement was reached.

It remains to be seen just how much support will be given.

Then there was the question of compensating developing countries for the loss and damage which has already resulted from climate change. Large historical polluters, such as the USA, the UK and various EU countries, were unwilling to agree to a compensation mechanism, fearing that any recognition of culpability could make them open to lawsuits and demands for financial compensation.

Other decisions

  • More than 100 countries at the meeting agreed to cut global methane emissions by at least 30 per cent from 2020 levels by 2030. Methane is a more powerful but shorter-living greenhouse gas than carbon. It is responsible for about a third of all human-generated global warming. China, India and Russia, however, did not sign up.
  • Again, more than 100 countries agreed to stop deforestation by 2030. These countries include Indonesia and Brazil, which has been heavily criticised for allowing large parts of the Amazon rainforest to be cleared for farming, such that the Amazon region in recent years has been a net emitter of carbon from the felling and burning of trees. The pledge has been met with considerable cynicism, however, as it unclear how it will be policed. Much of the deforestation around the world is already illegal but goes ahead anyway.
  • A mechanism for trading carbon credits was agreed. This allows countries which plant forests or build wind farms to earn credits. However, it may simply provide a mechanism for rich countries and businesses to keep emitting as usual by buying credits.
  • Forty-five countries pledged to invest in green agricultural practices to make farming more sustainable.
  • Twenty-two countries signed a declaration to create zero-emission maritime shipping routes.
  • The USA and China signed a joint declaration promising to boost co-operation over the next decade on various climate actions, including reducing methane emissions, tackling deforestation and regulating decarbonisation.

Blah, blah, blah or real action?

Many of the decisions merely represent targets. What is essential is for countries clearly to spell out the mechanisms they will use for achieving them. So far there is too little detail. It was agreed, therefore, to reconvene in a year’s time at COP27 in Egypt. Countries will be expected to spell out in detail what actions they are taking to meet their emissions targets and other targets such as ending deforestation and reducing coal-fired generation.

  6. If the world is to achieve net zero greenhouse gas emissions, should all countries achieve net zero or should some countries achieve net negative emissions to allow others to continue with net positive emissions (albeit at a lower level)?

Many economists argue that the most effective policy for dealing with climate change is carbon pricing. This reduces greenhouse gas (GHG) emissions in a way that minimises the costs to the economy.

For the policy to work effectively it is important that the price per tonne of CO2 equivalent (CO2e) does not vary with the activity that causes the emissions. In other words, whether you drive a car, heat your house using gas or travel by air, the GHGs you create need to be priced at a unified rate.

Governments can introduce carbon pricing in two different ways – cap-and-trade schemes and carbon taxes.

With a cap-and-trade policy, emission allowances are either issued or sold to the organisations covered by the scheme. They must accumulate enough of these allowances to match the actual level of emissions they produce or pay a large fine. After the initial allocation, allowances can be bought and sold in a secondary market and prices can be quite volatile.

With a carbon tax, the government directly sets the price of GHGs through the tax rate but has less control over the quantity of emissions.

Policy in the UK

The UK Emissions Trading Scheme – an example of a cap-and-trade scheme – clearly places a price on GHG emissions. As this price is determined by market forces it can vary on a daily basis. The scheme applies to electricity generation and other energy-intensive industries that account for approximately 30 per cent of all emissions.

Although the UK does not have a specific carbon tax, it does have a number of different taxes that have an impact on the environment. Some of these have stated environmental objectives (e.g. the Climate Change Levy) while the main rationale for others is to raise revenue (fuel duty).

The tax rates are typically set on the output or consumption of the good rather than on emissions. For example, the Climate Change Levy applies to businesses’ use of electricity, gas and coal rather than the emissions the energy generates. Fuel duty depends on the amount of petrol consumed rather than the emissions the burning of that fuel generates. Clearly, emissions will tend to rise in proportion to the consumption/production of the good, but the relationship will not be precise.

The structure of VAT also influences emissions. The standard rate of VAT in the UK is 20 per cent. However, a lower level is applied to some goods/services that produce significant emissions. For example, the rate on household consumption of gas is 5 per cent while commercial passenger flights are zero rated. These lower tax rates are an implicit subsidy for the people who consume these goods/services. It makes them cheaper relative to the price of other goods.

Impact of the policies

Researchers from the Institute for Fiscal Studies have recently tried to analyse the impact of this complex range of policies on the price of carbon. The results indicate wide variations depending on the activity that causes the emissions.

One of the most significant differences is between gas and electricity. For example, non-energy-intensive businesses pay a price of £229.10 per tonne of CO2e from electricity generation but only £30.50 per tonne from burning gas. The response to the incentives this creates is unsurprising. One of the biggest contributing factors to the fall in territorial emissions in the UK has come from the decarbonisation of electricity supply: i.e. the switch away from coal-fired generation.

The impact of government policy on UK households creates quite perverse incentives. Because of the lower rates of VAT, families receive an implicit subsidy of £24 per tonne CO2e when they use gas to heat their homes. When they use electricity, the source of energy that generates less emissions, they face a positive price of £137 per tonne of CO2e. Once again, the response to these incentives is unsurprising. Household emissions only fell by a relatively small amount between 1990 and 2018 because of the continued use of gas for heating and cooking.

Unsurprisingly many commentators have referred to carbon pricing in the UK as a confusing mess and have called for a unified rate across all activities to minimise the costs to the economy. Another important issue is the level at which a new unified rate is set. Some research by the Department for Business, Energy and Industrial Strategy suggests that the figure would have to be set between £122 and £36 per tonne of CO2e in order for the UK to reach its target of net zero emissions by 2050.

A higher unified rate would also create another problem – the distributional impact. Poorer households spend a much greater share of their income on electricity, heating and food and so would be disproportionately affected by the policy. For the policy to be politically acceptable, the government will need to find an effective way to compensate these groups.
