The UK government has made much of its spending commitments in the UK Budget and Spending Review delivered on 27 October 2021. Spending on transport infrastructure, green energy and health care figured prominently. The government claimed that these were to help achieve its objectives of economic growth, carbon reduction and ‘levelling up’. This means that government expenditure will be around 42% of GDP for the five years from 2022 (from 1988 to 2000 it averaged 36%). Although it temporarily rose to 52% in 2020/21, this was the result of supporting the economy through the pandemic. But does this mean that the government is now a ‘Keynesian’ one?
When the economy is in recession, as was the case in 2020 with the effects of the pandemic, increased government expenditure financed by borrowing rather than taxation is the classic Keynesian remedy to boost aggregate demand and close the output gap. The increased injection of spending works through the multiplier process to raise equilibrium national income and reduce unemployment.
But is this the objective of the extra spending announced in October 2021? To answer this, it is important to look at forecasts for the state of the economy with no change in government policy and at the balance of government expenditure and taxation resulting from the Budget. The first chart shows public sector net borrowing from 2006/7 and forecast to 2026/7. The green and red lines from 2021/22 onwards give the PSNB forecasts with and without the October 2021 measures.
As you can see, there was a large increase in the PSNB in 2020/21, reflecting the government’s measures to support firms and workers during the pandemic. (Click here for a PowerPoint of the chart.) This was very much a Keynesian response, where a large budget deficit was necessary to support aggregate demand. It was also to protect the supply side of the economy by enabling firms to survive.
But could the October 2021 announcements also be seen as a Keynesian response to the macroeconomic situation? If we redraw Chart 1, focusing just on the forecast period and adjust the vertical scale, we can see that the measures have a net effect of increasing the PSNB and thus acting as a stimulus to aggregate demand. (Click here for a PowerPoint of the chart.) The figures are shown in the following table, which shows the totals from Table 5.1 in the Autumn Budget and Spending Review 2021 document:
Effects of Spending Review and Budget 2021 on PSNB (+ = increase in PSNB)
At first sight, it would seem that the Budget was mildly expansionary. To see how much so, the Office for Budget Responsibility (OBR) measures the ‘fiscal stance’ using the ‘cyclically adjusted primary deficit (CAPD)’. This is PSNB minus interest payments and minus expenditures and tax revenues that fluctuate with the cycle and which therefore act as automatic stabilisers. The OBR’s forecast of the CAPD shows it to be expansionary, but decreasing over time. In 2021/22, there is forecast to be a net injection of around 3.2% (excluding ‘virus-related’ support), falling to 2.7% in 2022/23 and then gradually to around 0.6% by 2026/27. So it does seem that fiscal policy remains expansionary throughout the period, but less and less so.
But this alone does not make it ‘Keynesian’. A Keynesian Budget would be one that uses fiscal policy to adjust aggregate demand (AD) according to whether AD is forecast to be deficient or excessive without the Budget measures. To operate a Keynesian Budget, it would be necessary to forecast the output gap without any policy measures. If was forecast to be negative (a deficiency of demand, with equilibrium output below the potential level), then an expansionary policy should be pursued by raising government expenditure, cutting taxes or some combination of the two. If it was forecast to be positive (an excess demand, with equilibrium output above the potential level), then a contractionary/deflationary policy should be pursued by cutting government expenditure, raising taxes or some combination of the two.
So what is the forecast for the output gap? The OBR states that, after being negative in 2020
(–0.4% of potential GDP), it has risen substantially to 0.9% in 2021 with the rapid bounce back from the pandemic. But it is forecast to remain positive, albeit declining, until reaching zero in 2025. This is illustrated in Chart 3. (Click here for a PowerPoint of the chart.) So fiscal policy remains mildly expansionary until 2025, after having provided a considerable stimulus in 2021.
This is not normally what a Keynesian economist would recommend. Fiscal policy should be designed to achieve a zero output gap. With the output gap being substantially positive in 2021, there is a problem of excess demand. This can be seen in supply-chain difficulties and labour shortages in certain areas and higher inflation, with CPI inflation predicted by the OBR to rise to 4.4 per cent in 2022. The combination of higher prices, the rise in national insurance from April 2022 by 1.25 percentage points and the freezing of income tax personal allowances will squeeze living standards. And the cancelling of the £20 per week uplift to Universal Credit and no increase in its rate for the unemployed will put particular pressure on some of the poorest people.
The government is hoping that the rise in government expenditure will have beneficial supply-side effects and increase potential national income. The aim is to create a high-wage, high-skilled, high-productivity economy though investment in innovation, infrastructure and skills. As the OBR states, ‘The rebounding economy has provided the Chancellor with a Budget windfall that he has added to with tax rises that lift the tax burden to its highest since the early 1950s’.
It remains to be seen whether the extra spending on education, training, infrastructure and R&D will be sufficient to achieve the long-term growth the Chancellor is seeking. The OBR is forecasting very modest growth into the longer term when the bounce back has worked through. Real GDP is forecast to grow on average by just 1.5% per year from 2024 to 2026. What is more, the OBR sees permanent scarring effects of around 2% of GDP from the pandemic and around 4% of GDP from Brexit.

The development of open-source software and blockchain technology has enabled people to ‘hack’ capitalism – to present and provide alternatives to traditional modes of production, consumption and exchange. This has enabled more effective markets in second-hand products, new environmentally-friendly technologies and by-products that otherwise would have been negative externalities. Cryptocurrencies are increasingly providing the medium of exchange in such markets.
In a BBC podcast, Hacking Capitalism, Leo Johnson, head of PwC’s Disruption Practice and younger brother of Boris Johnson, argues that various changes to the way capitalism operates can make it much more effective in improving the lives of everyone, including those left behind in the current world. The changes can help address the failings of capitalism, such as climate change, environmental destruction, poverty and inequality, corruption, a reinforcement of economic and political power and the lack of general access to capital. And these changes are already taking place around the world and could lead to a new ‘golden age’ for capitalism.
The changes are built on new attitudes and new technologies. New attitudes include regarding nature and the land as living resources that need respect. This would involve moving away from monocultures and deforestation and, with appropriate technologies (old and new), could lead to greater output, greater equality within agriculture and increased carbon absorption. The podcast gives examples from the developing and developed world of successful moves towards smaller-scale and more diversified agriculture that are much more sustainable. The rise in farmers’ markets provides an important mechanism to drive both demand and supply.
In the current model of capitalism there are many barriers to prevent the poor from benefiting from the system. As the podcast states, there are some 2 billion people across the world with no access to finance, 2.6 billion without access to sanitation, 1.2 billion without access to power – a set of barriers that stops capitalism from unlocking the skills and productivity of the many.
These problems were made worse by the response to the financial crisis of 2007–8, when governments chose to save the existing model of capitalism by propping up financial markets through quantitative easing, which massively inflated asset prices and aggravated the problem of inequality. They missed the opportunity of creating money to invest in alternative technologies and infrastructure.
New technology is the key to developing this new fairer, more sustainable model of capitalism. Such technologies could be developed (and are being in many cases) by co-operative, open-source methods. Many people, through these methods, could contribute to the development of products and their adaptation to meet different needs. The barriers of intellectual property rights are by-passed.
New technologies that allow easy rental or sharing of equipment (such as tractors) by poor farmers can transform lives and massively increase productivity. So too can the development of cryptocurrencies to allow access to finance for small farmers and businesses. This is particularly important in countries where access to traditional finance is restricted and/or where the currency is not stable with high inflation rates.
Blockchain technology can also help to drive second-hand markets by providing greater transparency and thereby cut waste. Manufacturers could take a stake in such markets through a process of certification or transfer.
A final hack is one that can directly tackle the problem of externalities – one of the greatest weaknesses of conventional capitalism. New technologies can support ways of rewarding people for reducing external costs, such as paying indigenous people for protecting the land or forests. Carbon markets have been developed in recent years. Perhaps the best example is the European Emissions Trading Scheme (EMS). But so far they have been developed in isolation. If the revenues generated could go directly to those involved in environmental protection, this would help further to internalise the externalities. The podcasts gives an example of a technology used in the Amazon to identify the environmental benefits of protecting rain forests that can then be used to allow reliable payments to the indigenous people though blockchain currencies.

The global battle for fuel is expected to peak this winter. The combination of rising demand and a tightening of supply has sparked concerns of shortages in the market. Some people are worried about another ‘winter of discontent’. Gas prices have risen fivefold in Europe as a whole.
In the UK, consumers are likely to find that the natural gas needed to heat their homes this October will cost at least five times more than it did a year ago. This surge in wholesale gas prices has seen several UK energy suppliers stop trading as they are unable to make a profit. This is because of an energy price cap for some consumers and various fixed price deals they had signed with their customers.
There are thus fears of an energy crisis in the UK, especially if there is a cold winter. There are even warnings that during a cold snap, gas supply to various energy-intensive firms may be cut off. This comes at a time when some of these industries are struggling to make a profit.
Demand and supply
The current situation is a combination of long- and short-term factors. In spring 2020, the demand for gas actually decreased due to the pandemic. This resulted in low gas prices, reduced UK production and delayed maintenance work and investment along global supply chains. However, since early 2021, consumer demand for gas has soared. First, there was an increased demand due to the Artic weather conditions last winter. This was then followed by heatwaves in the USA and Europe over the summer, which saw an increase in the use of air conditioning units. With the increased demand combined with calm weather conditions, wind turbines couldn’t supply enough power to meet demand.
There has also been a longer-term impact on demand throughout the industry due to the move to cleaner energy. The transitioning to wind and solar has seen a medium-term increase in the demand for gas. There is also a long-term impact of the target for net zero economies in the UK and Europe. This has hindered investors’ willingness to invest in developing supplies of fossil fuels due the fact they could become obsolete over the next few decades.
Nations have also been unable to build up enough supplies for winter. This is partly due to Europe’s domestic gas stocks having declined by 30% per cent in the past decade. This heightened situation is leading to concerns that there will be black-outs or cut-offs in gas this winter.
Importation of gas
A concern for the UK is that it has scant storage facilities with no long-term storage. The UK currently has very modest amounts of storage – less than 6% of annual demand and some five times less than the average in the rest of Europe. It has been increasingly operating a ‘just-in-time model’, which is more affected by short-term price fluctuations in the wholesale gas market. With wind power generation remaining lower than average during summer 2021, more gas than usual has been used to generate electricity, leaving less gas to go into storage.
However, some argue that the problem is not just the UK’s physical supply of gas but demand for gas from elsewhere. Around half of the UK’s supply comes from its own production sites, while the rest is piped in from Europe or shipped in as liquefied natural gas (LNG) from the USA, Qatar and Russia. In 2019, the UK imported almost 20% of its gas through LNG shipments. However, Asian gas demand has grown rapidly, expanding by 50% over the past decade. This has meant that LNG has now become much harder to secure.
The issue is the price the UK has to pay to continue receiving these supplies. Some in the gas industry believe the price surge is only temporary, caused by economic disruptions, while many others say it highlights a structural weakness in a continent that has become too reliant on imported gas. It can be argued that the gas crisis has highlighted the lack of a coherent strategy to manage the gas industry as the UK transitions to a net zero economy. The lack of any industry investment in new capacity suggests that there is currently no business case for new long-term storage in the UK, especially as gas demand is expected to continue falling over the longer term.
Impact on consumers and industry
Gas prices for suppliers have increased fivefold over the past year. Therefore, many companies face a considerable rise in their bills. MSome may need to reduce or pause production – or even cease trading – which could cause job losses. Alternatively, they could pass on their increased costs to customers by charging them higher prices. Although energy-intensive industries are particularly exposed, every company that has to pay energy bills will be affected. Due to the growing concerns about the security of winter gas supplies those industries reliant on gas, such as the fertiliser industry, are restricting production, threatening various supply chains.
Most big domestic gas suppliers buy their gas months in advance, meaning they will most likely pass on the higher price rises they have experienced in the past few months. The increased demand and decreased supply has already meant meant that customers have faced higher prices for their energy. The UK has been badly hit because it’s one of Europe’s biggest users of natural gas – 85% of homes use gas central heating – and it also generates a third of the country’s electricity.
The rising bills are particularly an issue for those customers on a variable tariff. About 15 million households have seen their energy bills rise by 12% since the beginning of October due to the rise in the government’s energy price cap calculated by the regulator, Ofgem. A major concern is that this increase in bills comes at a time when the need to use more heating and lighting is approaching. It also coincides with other price rises hitting family budgets and the withdrawal of COVID support schemes.
Government intervention – maximum pricing
If the government feels that the equilibrium price in a particular market is too high, it can intervene in the market and set a maximum price. When the government intervenes in this way, it sets a price ceiling on certain basic goods or services and does not permit the price to go above that set limit. A maximum price is normally set for reasons of fairness and to benefit consumers on low incomes. Examples include energy price caps to order to control fuel bills, rent controls in order to improve affordability of housing, a cap on mobile roaming charges within the EU and price capping for regional monopoly water companies.
The energy price cap
Even without the prospect of a colder than normal winter, bills are still increasing. October’s increase in the fuel cap means that many annual household fuel bills will rise by £135 or more. The price cap sets the maximum price that suppliers in England, Wales and Scotland can charge domestic customers on a standard, or default tariff. The cap has come under the spotlight owing to the crisis among suppliers, which has seen eleven firms fold, with more expected.
The regulator Ofgem sets a price cap for domestic energy twice a year. The latest level came into place on 1 October. It is a cap on the price of energy that suppliers can charge. The price cap is based on a broad estimate of how much it costs a supplier to provide gas and electricity services to a customer. The calculation is mainly made up of wholesale energy costs, network costs such as maintaining pipes and wires, policy costs including Government social and environmental schemes, operating costs such as billing and metering services and VAT. Therefore, suppliers can only pass on legitimate costs of supplying energy and cannot charge more than the level of the price cap, although they can charge less. A household’s total bill is still determined by how much gas and electricity is used.
- Those on standard tariffs, with typical household levels of energy use, will see an increase of £139.
- People with prepayment meters, with average energy use, will see an annual increase of £153.
- Households on fixed tariffs will be unaffected. However, those coming to the end of a contract are automatically moved to a default tariff set at the new level.
Ordinarily, customers are able to shop around for cheaper deals, but currently, the high wholesale prices of gas means that cheaper deals are not available.
Despite the cap limiting how much providers can raise prices, the current increase is the biggest (and to the highest amount) since the cap was introduced in January 2019. As providers are scarcely making a profit on gas, there are concerns that a further increase in wholesale prices will cause more suppliers to be forced out of business. Ofgem said that the cap is likely to go up again in April, the next time it is reviewed.
Conclusion
The record prices being paid by suppliers and deficits in gas supply across the world have stoked fears that the energy crisis will get worse. It comes at a time when households are already facing rising bills, while some energy-intensive industries have started to slow production. This has started to dent optimism around the post-pandemic economic recovery.
Historically, UK governments have trusted market mechanisms to deliver UK gas security. However, consumers are having to pay the cost of such an approach. The price cap has meant the UK’s gas bills have until now been typically lower than the EU average. However, the rise in prices comes on top of other economic problems such as labour shortages and increasing food prices, adding up to an unwelcome rise in the cost of living.

With waiting lists in the NHS at record highs and with the social care system in crisis, there have been growing calls for increased funding for both health and social care. The UK government has just announced tax rises to raise more revenue for both services and has specified new limits on the amounts people must pay towards their care.
In this blog we look at the new tax rises and whether they are fair. We also look at whether the allocation of social care is fair. Clearly, the question of fairness is a contentious one, with people having very different views on what constitutes fairness between different groups in terms of incomes, assets and needs.
Funding
In terms of funding, the government has, in effect, introduced a new tax – the ‘health and social care levy’ to come into effect from April 2022. This will see a tax of 1.25% on the earned incomes of workers (both employees and the self-employed) and 1.25% on employers, making a total of 2.5% on employment income. It will initially be added to workers’ and employers’ national insurance (NI) payments. Currently national insurance is only paid by those below pension age (66). From 2023, the 1.25% levy will be separated from NI and will apply to pensioners’ earned income too.
The starting point for workers will be the same as for the rest of national insurance, currently £9568. Above this, the additional marginal rate of 1.25% will apply to all earned income. This will mean that a person earning £20 000 would pay a levy of £130.40, while someone earning £100 000 would pay £1130.40.
There will also be an additional 1.25% tax on share dividends. However, there will be no additional tax on rental income and capital gains, and on private or state pensions.
It is estimated that the levy will raise around £14 billion per year (0.7% of GDP or 1.6% of total tax revenue), of which £11.2 billion will go to the Department of Health and Social Care in 2022/23 and £9 billion in 2023/24. This follows a rise in income tax of £8 billion and corporation tax of £17 billion announced in the March 2021 Budget. As a result, tax revenues from 2022/23 will be a higher proportion of GDP (just over 34%) than at any time over the past 70 years, except for a short period in 1969/70.
Is the tax fair?
In a narrow sense, it can be argued that the levy is fair, as it is applied at the same percentage rate on all earned income. Thus, the higher a person’s earnings, the greater the amount they will pay. Also, it is mildly progressive. This is because, with a levy-free allowance of just under £10 000, the levy as a proportion of income earned rises gently as income rises: in other words, the average levy rate is higher on higher earners than on lower earners.
But national insurance as a whole is regressive as the rate currently drops from 12% to 2%, and with the levy will drop from 13.25% to 3.25%, once the upper threshold is reached. Currently the threshold is £50 270. As incomes rise above that level, so the proportion paid in national insurance falls. Politically, therefore, it makes sense to decouple the levy from NI, if it is being promoted as being fair as an additional tax on income earners.
Is it fair between the generations? Pensioners who earn income will pay the levy on that income at the same rate as everyone else (but no NI). But most pensioners’ main or sole source of income is their pensions and some, in addition, earn rent on property they own. Indeed, some pensioners have considerable private pensions or rental income. These sources of income will not be subject to the levy. Many younger people whose sole source of income is their wages will see this as unfair between the generations.
Allocation of funds
For the next few years, most of the additional funding will go to the NHS to help reduced waiting lists, which rocketed with the diversion of resources to treating COVID patients. Of the additional £11.2 billion for health and social care in 2022/23, some £9.4 billion will go to the NHS; and of the £9 billion in 2023/24, some £7.2 billion will go to the NHS. This leaves only an additional £1.8 billion each year for social care.
The funding should certainly help reduce NHS waiting lists, but the government refused to say by how much. Also there is a major staff shortage in the NHS, with many employees having returned to the EU following Brexit and fewer new employees coming from the EU. It may be that the staff shortage will push up wages, which will absorb some of the increase in funding.
The additional money from the levy going to social care would be wholly insufficient on its own to tackle the crisis. As with the NHS, the social care sector is facing an acute staff shortage, again aggravated by Brexit. Wages are low, and when travel time between home visits is taken into account, many workers receive well below the minimum wage. Staff in care homes often find themselves voluntarily working extra hours for no additional pay so as to provide continuity of care. Often levels of care are well below what carers feel is necessary.
Paying for social care
The government also announced new rules for the level of contributions by individuals towards their care costs. The measures in England are as follows. The other devolved nations have yet to announce their measures.
- Those with assets of less than £20 000 will not have to contribute towards their care costs from their assets, but may have to contribute from their income.
- Those with assets between £20 000 and £100 000 will get means-tested help towards their care costs.
- Those with assets over £100 000 will initially get no help towards their care costs. This is increasing from the current limit of £23 250
- There will be a limit of £86 000 to the amount people will have to contribute towards their care costs over their lifetime (from October 2023). These costs include both care in a care home and care at home.
- These amounts will apply only to care costs and not to the board and lodging costs in care homes. The government has not said how much people could be expected to contribute towards these living costs. A problem is that care homes generally do not itemise costs and hence it may be hard to distinguish care costs from living costs.
- Where people’s care costs are fully or partly covered, these will be paid by their local authority.
- A house will only count as a person’s asset if the person is going into a care home and it is not occupied by a spouse or partner. All financial assets, by contrast, will count.
- Many people in care homes will not be judged to be frail enough to be in receipt of support from their local authority. These people’s expenditure would not count towards the cap.
Setting the cap to the amount people must pay at the relatively high figure of £86 000 may ease the pressure on local authorities, as many people in care homes will die before the cap is reached. However, those who live longer and who get their care paid for above the cap, will pay no more no matter what their level of assets, even though they may be very rich. This could be seen to be unfair. A fairer system would be one where a proportion of a person’s assets had to be used to pay for care with no upper limit.
Also, the £1.8 billion is likely to fall well short of what local authorities will need to bring social care back to the levels considered acceptable, especially as the asset limit to support is being raised from £23 250 to £100 000. Local authority expenditure on social care fell by 7.5% per person in real terms between 2009/10 and 2019/20. This means that local authorities may have to increase council tax to top up the amount provided by the government from the levy.

The UN’s Intergovernmental Panel on Climate Change (IPCC) has just published the first part of its latest seven-yearly Assessment Report (AR6) on global warming and its consequences (see video summary). The report was prepared by 234 scientists from 66 countries and endorsed by 195 governments. Its forecasts are stark. World temperatures, already 1.1C above pre-industrial levels, will continue to rise. This will bring further rises in sea levels and more extreme weather conditions with more droughts, floods, wildfires, hurricanes and glacial melting.
The IPCC looked at a number of scenarios with different levels of greenhouse gas emissions. Even in the most optimistic scenarios, where significant steps are taken to cut emissions, global warming is set to reach 1.5C by 2040. If few or no cuts are made, global warming is predicted to reach 4.4C by 2080, the effects of which would be catastrophic.
The articles below go into considerable detail on the different scenarios and their consequences. Here we focus on the economic causes of the crisis and the policies that need to be pursued.
Global success in reducing emissions, although partly dependent on technological developments and their impact on costs, will depend largely on the will of individuals, firms and governments to take action. These actions will be influenced by incentives, economic, social and political.
Economic causes of the climate emergency
The allocation of resources across the world is through a mixture of the market and government intervention, with the mix varying from country to country. But both market and government allocation suffer from a failure to meet social and environmental objectives – and such objectives change over time with the preferences of citizens and with the development of scientific knowledge.
The market fails to achieve a socially efficient use of the environment because large parts of the environment are a common resource (such as the air and the oceans), because production or consumption often generates environmental externalities, because of ignorance of the environmental effects of our actions, and because of a lack of concern for future generations.
Governments fail because of the dominance of short-term objectives, such as winning the next election or appeasing a population which itself has short-term objectives related to the volume of current consumption. Governments are often reluctant to ask people to make sacrifices today for the future – a future when there will be a different government. What is more, government action on the environment which involves sacrifices from their own population, often primarily benefit people in other countries and/or future generations. This makes it harder for governments to get popular backing for such policies.
Economic systems are sub-optimal when there are perverse incentives, such as advertising persuading people to consume more despite its effects on the environment, or subsidies for industries producing negative environmental externalities. But if people can see the effects of global warming affecting their lives today, though fires, floods, droughts, hurricanes, rising sea levels, etc., they are more likely to be willing to take action today or for their governments to do so, even if it involves various sacrifices. Scientists, teachers, journalists and politicians can help to drive changes in public opinion through education and appealing to people’s concern for others and for future generations, including their own descendants.
Policy implications of the IPCC report
At the COP26 meeting in Glasgow in November, countries will gather to make commitments to tackle climate change. The IPCC report is clear: although we are on course for a 1.5C rise in global temperatures by 2040, it is not too late to take action to prevent rises going much higher: to avoid the attendant damage to the planet and changes to weather systems, and the accompanying costs to lives and livelihoods. Carbon neutrality must be reached as soon as possible and this requires strong action now. It is not enough for government to set dates for achieving carbon neutrality, they must adopt policies that immediately begin reducing emissions.
The articles look at various policies that governments can adopt. They also look at actions that can be taken by people and businesses, actions that can be stimulated by government incentives and by social pressures. Examples include:
- A rapid phasing out of fossil fuel power stations. This may require legislation and/or the use of taxes on fossil fuel generation and subsidies for green energy.
- A rapid move to green transport, with investment in charging infrastructure for electric cars, subsidies for electric cars, a ban on new petrol and diesel vehicles in the near future, investment in hydrogen fuel cell technology for lorries and hydrogen production and infrastructure, cycle lanes and various incentives to cycle.
- A rapid shift away from gas for cooking and heating homes and workplaces and a move to ground source heating, solar panels and efficient electric heating combined with battery storage using electricity during the night. These again may require a mix of investment, legislation, taxes and subsidies.
- Improvements in energy efficiency, with better insulation of homes and workplaces.
- Education, public information and discussion in the media and with friends on ways in which people can reduce their carbon emissions. Things we can do include walking and cycling more, getting an electric car and reducing flying, eating less meat and dairy, reducing food waste, stopping using peat as compost, reducing heating in the home and putting on more clothes, installing better insulation and draught proofing, buying more second-hand products, repairing products where possible rather than replacing them, and so on.
- Governments requiring businesses to conduct and publish green audits and providing a range of incentives and regulations for businesses to reduce carbon emissions.
It is easy for governments to produce plans and to make long-term commitments that will fall on future governments to deliver. What is important is that radical measures are taken now. The problem is that governments are likely to face resistance from their supporters and from members of the public and various business who resist facing higher costs now. It is thus important that the pressures on governments to make radical and speedy reductions in emissions are greater than the pressures to do little or nothing and that governments are held to account for their actions and that their actions match their rhetoric.
