Climate change needs urgent action by all countries, and by all means. All countries agreed in the Paris Agreement to keep temperature “well below 2℃” and pursue efforts to keep global temperature increase below 1.5℃. Virtually all countries have nationally determined contributions, but currently these are on a path to 3℃ or more. The negative impacts of climate change increase as the temperature increase – and the poor suffer the most.
As part of its contribution to the global effort on climate change, South Africa is introducing the Carbon Tax Act. It comes into effect on 1 June 2019 and is a great step for the country; it also puts South Africa in the company of a steadily-increasing number of countries that are pricing carbon. There are 46 national jurisdictions and 28 subnational jurisdictions that have implemented a price on carbon, or are scheduled to do so, according to the Carbon Pricing dashboard created by the World Bank
Companies in South Africa will now pay a small amount each time they emit a ton of greenhouse gases. Putting a price on carbon is a key way of responding to the climate emergency. It will also raise awareness and improve reporting on emissions. The tax revenues should be used to ensure benefits to poor communities, and the tax will need to be increased over time to provide a long-term price signal to decarbonise the economy.
How it works
The carbon tax is being introduced at a much lower rate than needed in the longer term. The nominal amount of carbon tax that a company will pay is R120 per ton CO2-eq.
But multiple allowances, including a 60% “basic” tax-free allowance, means big emitting companies pay at most R48/ton. The tax is payable by companies which exceed the threshold of carbon emissions. Other further “allowances” mean that several of South Africa’s major emitting companies will pay a minimum of R6/ton. At current exchange rates, that is as little as $0.42/ton, much lower than required globally.
The High Level Commission on Carbon Prices recently reported that by 2030, countries should be looking at a carbon price of US$50–100/tCO2. Given the rate of change of key technologies for mitigation, the appropriate tax level will have to be periodically assessed. But there is no doubt that South Africa’s current tax rate is too low to transform the economy.
The tax will be paid by companies to the South African Revenue Services (SARS). As for other taxes, SARS collects the revenue for the general fiscus. Revenue should be used for two purposes, which should be funded on budget.
To fund programmes that provide access to cleaner and safer energy to the poor. Poor households should pay less for energy under a carbon tax-revenue scheme, rather than more.
Energy-intensive firms should be able to claim transitional assistance if they pay the full tax, contribute to socio-economic development, and agree to reduce where they can. The assistance would be money clawed back by the company, to fund lower-carbon activities – until this is no longer needed.
How the tax could be used
Most important from an ethical point of view is that the tax should be implemented in a way that ensures poor communities pay less for energy. This can be done by using revenues to fund programmes to reduce energy poverty.
Various scenarios exist for carbon tax revenues, depending on whether companies on average pay R6 or R48 per ton CO2-eq. The revenues could fund the national budget for electrification – if companies paid a “medium” carbon tax of R30 per ton.
Another option is that hundreds of thousands, and up to tens of millions, of households could be given 5kg liquified petrolum gas free each month, extending free basic electricity to other energy.
A few hundred thousand better houses – warmer in winter with better insulation and with fewer health impacts due to use of cleaner fuels indoors – could be funded from carbon tax revenue. Or the country could decide to subsidise at least 100 000 rooftop solar systems per year for poor households.
The carbon tax should be complemented by other mitigation measures, such as carbon budgets for companies and a cap on greenhouse gas emission from electricity in the integrated resource plan, the country’s national electricity plan.
Given the climate emergency, all these measures need pursuing and the understanding of how they best relate to one another. Many other countries have carbon taxes, emissions trading, indirect carbon pricing and regulations, and South Africa could learn from their experiences. These countries include the EU, Scandinavian countries, China, India and increasing numbers of developing countries.
Whatever approach it takes from here, South Africa’s decision to introduce a carbon tax should be hailed as an important milestone in the transition to a low-carbon and climate resilient economy and society.

Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming
by Paul Hawken and Tom Steyer
In the face of widespread fear and apathy, an international coalition of researchers, professionals, and scientists have come together to offer a set of realistic and bold solutions to climate change. One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. Available On Amazon
Designing Climate Solutions: A Policy Guide for Low-Carbon Energy
by Hal Harvey, Robbie Orvis, Jeffrey Rissman
With the effects of climate change already upon us, the need to cut global greenhouse gas emissions is nothing less than urgent. It’s a daunting challenge, but the technologies and strategies to meet it exist today. A small set of energy policies, designed and implemented well, can put us on the path to a low carbon future. Energy systems are large and complex, so energy policy must be focused and cost-effective. One-size-fits-all approaches simply won’t get the job done. Policymakers need a clear, comprehensive resource that outlines the energy policies that will have the biggest impact on our climate future, and describes how to design these policies well.

This Changes Everything: Capitalism vs. The Climate
by Naomi Klein
In This Changes Everything Naomi Klein argues that climate change isn’t just another issue to be neatly filed between taxes and health care. It’s an alarm that calls us to fix an economic system that is already failing us in many ways. Klein meticulously builds the case for how massively reducing our greenhouse emissions is our best chance to simultaneously reduce gaping inequalities, re-imagine our broken democracies, and rebuild our gutted local economies. She exposes the ideological desperation of the climate-change deniers, the messianic delusions of the would-be geoengineers, and the tragic defeatism of too many mainstream green initiatives. And she demonstrates precisely why the market has not—and cannot—fix the climate crisis but will instead make things worse, with ever more extreme and ecologically damaging extraction methods, accompanied by rampant disaster capitalism.
