Legislature Keeps Plodding Along On Carbon Tax

In May 2013 National Treasury released the long-awaited carbon tax policy paper, which serves as an update to the carbon tax discussion paper on the introduction of a carbon-pricing mechanism in South Africa that the government released in December 2010.

The carbon tax discussion paper was preceded by an announcement in 2009 that the government is committed to reducing greenhouse gas emissions by 34% by 2020.

The underlying rationale for reducing the emission of greenhouse gases is to "facilitate an environmentally sustainable economic development and growth path for South Africa." This would be achieved by pricing carbon emissions in a way that affects producer and consumer behaviour and addresses climate change.

The updated policy paper aims to refine the specific features of carbon tax that were discussed in the 2012 Budget Review. This article highlights some of the issues raised in the policy paper:

Carbon tax or an emissions trading scheme?

A significant issue addressed in the policy paper is the mechanism that would be used to price carbon. In principle there are two main market-based mechanisms that could be used to price carbon, namely, carbon taxes and emissions trading schemes. Carbon taxes work by pricing the emissions directly, whereas emissions trading schemes operate by limiting the amount of greenhouse gases that are allowed to be emitted.

The policy paper makes it clear that in South Africa the most appropriate pricing mechanism, in the short to medium term, would be a carbon tax rather than an emissions trading scheme. This had  already been established in the 2010 discussion paper continued 21 June 2013.

The main reason given for preferring a carbon tax over and emissions trading scheme is that an emissions trading scheme mechanism will require a sufficient number of entities participating and adequate trading volumes to generate an appropriate carbon price. As the energy sector is dominated  by a relatively small number of suppliers and South Africa is a developing country, it may fail to meet these requirements.

Designing a carbon tax

The 2010 carbon tax discussion paper proposed three options for establishing a base for a carbon tax:

(i) direct measure of greenhouse gas emissions; 
(ii) quantity of fossil fuel input for coal, crude oil and natural gas; and 
(iii) energy outputs (electricity and transport fuels).

The policy paper proposes that the best option would be to impose a levy directly on the emissions of actual greenhouse gases or carbon dioxide equivalents. However, such a tax on actual emissions would constitute an administrative burden.

Accordingly, the policy paper proposes that the most preferred option is for a fuel input tax. The carbon tax will only cover direct emissions, also known as scope 1 emissions, in the tax base. These are emissions that result directly from fuel combustion and gasification and from non-energy industrial processes.

Tax-free thresholds for certain sectors

Certain sectors that are vulnerable or exposed in respect of competitiveness in trade and carbon intensive sectors will enjoy relief in the form of a variable tax-free percentage-based threshold for the first five years. It is anticipated that there will be a move towards absolute thresholds after that period.

Additional offset incentives will also be available to companies that introduce certain measures to curb carbon emissions.

The agricultural, forestry and land, and waste sectors will enjoy a 100% threshold for the first five years. The steel, cement and chemical sectors will enjoy a maximum threshold of 80%, the petroleum sector 70% and the electricity sector 60%.

Proposed carbon tax rate

In theory, the aim of the proposed carbon tax is to correct the existing prices of goods and services that generate excessive greenhouse gas emissions so that they reflect the social costs of such emissions.

The policy paper proposes that as of 1 January 2015, a carbon tax is introduced at R120 per ton of carbon dioxide equivalent.

If the tax free thresholds are taken into account, the effective tax rate will be substantially below the rate of R120 per ton of carbon dioxide equivalent during the first five year period.

It is also proposed that the carbon tax rate of R120 per ton of carbon dioxide equivalent will be increased at a rate of 10% per year until 31 December 2019.


In light of the above, it is clear that the arguments presented in the 2010 discussion paper and the recently updated policy paper are on par with each other. Significantly, both the discussion paper and the policy paper are strongly in favour of the carbon tax option as opposed to the emissions trading option. It would appear that the issue is no longer open for debate and South Africa will see a carbon tax, sooner or later. It remains to be seen whether the carbon tax legislation will be ready for implementation by 1 January 2015.

From a socio-economic perspective, the policy paper appears to underplay the potential effect that a carbon tax might have on the economy in terms of inflation and the spending power of economic participants who are already over-taxed. These issues still need to be adequately addressed.

Perhaps the most concerning issue relating to the proposed carbon tax is whether the tax collected by government will genuinely be put to use in respect of renewable energy and other measures to create a clean and sustainable environment, and not simply be seen as another revenue source for funding unrelated projects. 

The public is invited to comment on the carbon tax policy paper by 2 August 2013.



Section 240A of the Tax Administration Act, 2011 (as amended) requires that all tax practitioners register with a recognized controlling body before 1 July 2013. It is a criminal offense to not register with both a recognized controlling body and SARS.
