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.

At the annual World Economic Forum (WEF) in Davos, Switzerland, world political and business leaders are meeting to discuss pressing economic issues of the day. This year, one of the key themes is climate change and “how to save the planet”.

The approaches of leaders to the climate crisis, however, differ enormously. At the one extreme there are those who deny that emissions have caused climate change, or who reluctantly acknowledge climate change but think that governments need to do nothing and that technological advances in green energy and transport will be sufficient to curb global warming. This has been the approach of President Trump, President Bolsonaro of Brazil and Prime Minister Scott Morrison of Australia. They may claim to support the general goals of reducing greenhouse gases, but are keen to protect their coal and oil industries and, in the case of Brazil, to continue cutting down the Amazon rain forest to support mining, ranching and the growing of crops.

At his speech at the WEF, President Trump said that he supported the initiative to plant one trillion trees worldwide to act as a carbon sink. However, he gave no details of just what the nature of the support would be. Would there be subsidies or tax breaks, for example, for landowners to plant trees? In the meantime, his administration has relaxed regulations to curb air and water pollution. And he has withdrawn the USA from the Paris climate agreement.

Other leaders, urged on by activists, such as Greta Thunberg, have talked about tougher action to tackle emissions. Countries such as Canada, Norway and the EU countries have adopted a number of initiatives. Policies range from taxing emissions, capping/regulating emissions with penalities for those breaching the limits, tradable permits, subsidising green alternatives, setting local emissions targets with incentives for meeting them, investing in green infrastructure such as roadside charging points for electric vehicles, making environmental education part of a national curriculum, investing in public transport, and so on. But, say, activists, only large-scale measures that truly recognise the scale of the climate emergency will be sufficient.

The year starts with climate being addressed at Davos; it ends with the annual Conference of the Parties (COP26) to the United Nations Framework Convention on Climate Change (UNFCCC). This year it will be in Glasgow. There is much hope pinned on this conference, given the growing realisation of the effects of climate change, from bush fires in Australia, to floods in Indonesia and other parts of southeast Asia, to more extreme hurricanes/typhoons, to rapidly melting glaciers and retreating sea ice, to rising sea levels, to crop failures and the displacement of humans and the destruction of wildlife and habitat.

COP25 in Madrid made little progress; it is hoped that COP26 will be much more successful. Sir David Attenborough has warned that the world faces a ‘climate crisis moment’. He hopes that the world will be ready to take much stronger action at COP26.

But there remains the fundamental economic problem of the tragedy of the commons. As long as the atmosphere and other parts of the environment are free to ‘use’ to pollute, and as long as the costs of doing so are borne largely by people other than the direct polluters, the market will fail to provide a solution. Australia’s bush fires can be directly attributed to climate change and climate change is exacerbated by coal-fired power stations. But Australia’s use of coal as a power source is only a tiny contributor to global climate change. Presumably, the Australian government would rather get a ‘free ride’ off other countries’ policies to cut emissions rather than bearing the economic cost of reducing coal-fired generation itself for little gain in terms of reduced global emissions.

However, people are not entirely selfish. Many are willing to make personal sacrifices to lead a more environmentally sustainable life. Many people, for example, are choosing electricity tariffs that are slightly higher but where the electricity is generated with zero carbon emissions. Firms have shown a readiness to respond to demands from their consumers for more sustainable products.
