A fairer way to help developing economies decarbonise

Global carbon pricing is an essential part of any long-term solution to the climate crisis, but advanced economies need to provide the developing world with a carrot and not just a stick.

With US President-elect Joe Biden’s incoming administration promising a fresh, rational approach to climate change, now is an ideal time to make the case for a World Carbon Bank that would transfer and coordinate aid and technical assistance to help developing countries decarbonise. 

Biden’s proposed Green New Deal in the US and the European Commission’s European Green Deal have laudable environmental goals but are too inward-looking. When an entire building is burning, to concentrate firefighting resources on one floor would only delay, not prevent, its destruction.

According to the International Energy Agency (IEA), almost all the net growth in carbon dioxide emissions over the next two decades will come from emerging markets. Although China recently pledged to achieve zero net emissions by 2060, it is sobering to consider that it accounts for half of the world’s coal output and half of its coal consumption.

India, too, is highly dependent on its plentiful coal reserves and is likely to remain so despite strong advances in solar power. For all the fanfare accompanying the 2015 Paris climate agreement, the share of clean energy in global energy investment is still only around 34%, almost exactly the level five years ago. Wind and solar account for only 8% of global energy. The IEA estimates that allowing existing power plants to operate for the remainder of their expected lifespans in their current form would by itself cause global temperatures to rise by 1.7°C relative to pre-industrial levels.

Right now, the most widely discussed approach to encouraging developing economies to cut their CO2 emissions is a carbon border tax on imports from countries without adequate carbon-pricing systems. The European Union is currently considering such a measure, and the Climate Leadership Council (whose members include incoming US Treasury Secretary Janet Yellen) also has advocated it.

Economists almost universally favour carbon taxes (Europe’s carbon-pricing system is a clumsier version) so that producers and consumers take account of how their actions affect the global commons. A border-tax adjustment is aimed at prodding developing economies to introduce their own carbon taxes. The policy is conceptually sound, but is too static and difficult to implement.

For starters, developing economies have neither the resources nor the technology to transform themselves overnight. Part of the reason advanced economies have been able to mitigate their COemissions is that global manufacturing has migrated to emerging markets that have invested heavily in energy.

The average age of coal plants in Asia is 12 years, compared to 43 years in advanced economies. Given that the lifespan of a coal plant is about 50 years, and coal is one of the few natural resources that China and India possess in abundance, the cost to developing Asia of decommissioning its coal plants is huge. And then there is Africa, where the number of people lacking access to electricity has risen during the Covid-19 pandemic, to almost 600 million.

The gap between the developing world’s ability to deal with climate change and the ambitious plans being discussed in advanced economies is just another example of the huge disparity in wealth and resources between the Global North and the Global South. In response to the Covid-19 crisis, for example, advanced economies marshalled fiscal and credit support in 2020 averaging over 16% of GDP, compared to 6% in emerging markets and 2% in developing economies, according to the International Monetary Fund (IMF). And this wide gap does not take into account the potential for pandemic-related debt build-ups to morph into a full-blown developing-country debt crisis over the next couple of years, making decarbonisation even more difficult.

Global carbon pricing is an essential part of any long-term solution to the climate crisis, but advanced economies need to provide the developing world with a carrot and not just a stick. This should come in the form of highly concessional financing, combined with technical expertise and sharing of best practices – all guided by a World Carbon Bank.

The IMF, the World Bank, and regional development banks have an important role to play, but their mandates are too diffuse for them to deal effectively with the climate challenge on their own. Meanwhile, those who think that government-to-government assistance should not play any role in climate solutions need to bear in mind that state-owned firms, which are not terribly responsive to economic incentives, increasingly dominate the global coal industry.

Is it too optimistic to think that inwardly focused advanced economies will ever be willing to earmark large amounts of aid – at least $100-200 billion per year – to help the developing world meet climate goals? The response to the Covid-19 crisis so far offers little encouragement; the G20’s Debt Service Suspension Initiative has delivered a few billion dollars of relief to 40 very poor countries, but that pales in comparison to the trillions that rich countries have spent on their own citizens. An enhanced carbon tax or pricing regime could be one source of sustainable funding over the longer term, but the problem is too urgent to wait for this to fall into place.

The goal of achieving zero net CO2 emissions by 2050, which the EU has adopted and the US is likely to do soon, is praiseworthy. But not-in-my-backyard, or NIMBY, environmentalism is no way to solve a global problem. DM/BM

The goal of attaining nett zero carbon emissions is not good enough. That would mean that for another 30 years we would still be increasing the CO2 content in the atmosphere.We already know that the goals of the Paris Accord are not attainable and we are staring down the barrel at a future which may be 3, 4 or more degrees warmer very quickly. We need to sequester carbon urgently and South Africa has several mechanisms to do this. We need to adopt regenerative no till agriculture urgently which also has the advantage of preserving our topsoil. Secondly, we need to proceed with the huge opportunity for regenerating the Thicket biome in the Eastern Cape by planting spekboom. South Africa already has a Carbon Tax but the biggest obstacle for anyone wanting to take advantage of these natural means of carbon sequestration is verification. There are methods but they are expensive and until this problem is solved it is difficult to justify the investments. For instance, it can cost between R5000-R15000/ha to plant spekboom which will sequester up to 200/mt CO2/ha over the next 20 years

  • Really good points made by Stalker! Perhaps DM /Kevin Bloom should do some investigative work on regenerative no-till agriculture in SA – the extent to which this is happening and its potential, as well as the policies of govt and big agric institutions regarding this

  • In addition to no or low tillage agriculture, there is also the opportunity to increase soil carbon through the addition of biochar. This serves not only to sequester carbon for decades, but also improves soil quality, fertility and water retention capacity. Biochar can be made from a wide range of organic wastes.
