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”.

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.

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.

With the bounce-back from the pandemic, many countries have experienced supply-chain problems. For example, the shortage of lorry drivers in the UK and elsewhere (see the blog Why is there a driver shortage in the UK?) has led to empty shelves, fuel shortages and rising prices. The problem has been exacerbated by a lack of stock holding. Holding minimum stocks has been part of the modern system of ‘just-in-time’ (JIT) supply-chain management.
JIT involves involves highly integrated and sophisticated supply chains. Goods are delivered to factories, warehouses and shops as they are needed – just in time. Provided firms can be sure that they will get their deliveries on time, they can hold minimum stocks. This enables them to cut down on warehousing and its associated costs. The just-in-time approach to supply-chain management was developed in the 1950s in Japan and since the 1980s has been increasingly adopted around the world, helped more recently by sophisticated ordering and tracking software.
If supply chains become unreliable, however, JIT can lead to serious disruptions. A hold-up in one part of the chain will have a ripple effect along the whole chain because there is little or no slack in the system. 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.
JIT works well when sources of supply and logistics are reliable and when demand is predictable. The pandemic is causing many logistics and warehousing managers to consider building a degree of slack into their systems. This might involve companies having alternative suppliers they can call on, building in more spare capacity and having their own fleet of lorries or warehousing facilities that can be hired out when not needed but can be relied on at times of high demand.
When the ‘bounce back’ subsides, so may the current supply chain bottlenecks. But the rethinking that has been generated by the current problems may see new patterns emerge that make supply chains more flexible without becoming more expensive.
