Climate Change

Ever since the National Treasury published its discussion paper on environmental reform in 2006, a carbon tax has been on the cards in South Africa. In this year’s National Budget, it was mentioned that a carbon tax would be formally announced in the 2013 National Budget and implemented before the end of the 2013-14 fiscal year. Given the public outcry that preceded the planned implementation of the e-toll system in Gauteng in April this year (despite the e-tolls first being announced by Sanral in March 2008, and the first indicative tariffs being published in February 2011), it is prudent to consider whether the South African public is prepared for, or even aware of, the impeding carbon tax. One readily available metric for measuring public awareness is the number of web searches devoted to a topic.

Over the same period, the contribution of the tertiary sector (which is typically less energy-intensive than the primary and secondary sectors) to GDP increased by 8 percent (to 69.6 percent), while the contribution of the primary sector fell by almost a third (to 7.9 percent). It is clear that the energy intensity picture in South Africa is changing over time. What is not clear yet, however, is whether this is predominantly due to increased energy efficiency and decoupling between economic growth and energy use, or whether this is being driven by structural changes to the South African economy.

A cost-benefit analysis is only as good as the assumptions that underlie it. If a rigorous assessment of the relative merits of exploiting Karoo Basin shale gas is to be undertaken, it is important that these two factors (amongst other critical assumptions – on both the cost and benefit side of the analysis) are considered in detail.

The Minister of Finance on Wednesday reiterated in his budget speech that the need for carbon pricing in South Africa is accepted. This should not have surprised anyone – the fact that a carbon tax was on the cards was clearly signalled in last year’s budget and a discussion paper dealing with carbon taxes in South Africa was released in December 2010. What was more surprising, however, was that the implementation date for a carbon tax, its proposed design features, and its suggested levels were included in the Budget Review.

The release of National Treasury’s carbon tax discussion document late last year raised carbon pricing higher on the economic agenda. The private sector is against a carbon tax, calling for an emissions trading scheme instead.
