Which SA companies have decreased their emissions in 2011?

The regular publication of the Carbon Disclosure Project (CDP) report for South Africa provides an opportunity to assess which companies in the SA JSE top 100 have decreased their emissions. 

 The CDP reports don’t report on year on year changes in greenhouse gas (GHG) emissions of companies.  This is probably because the reasons for changes in emissions often have very little to do with the emission efficiency (production per unit emission) of the companies involved.  For instance if a company expands and takes on new staff its emissions will go up and similarly if a company closes a division its emissions will go down.  However, since avoiding the impacts of climate change requires an absolute reduction in total GHG emissions it is still interesting to consider which company’s emissions are decreasing and by how much.

The following graph shows the six JSE companies that experienced the highest percentage decreases in scope one and scope two emissions from 2010 to 2011. The figures are based on the CDP reports of 2010 and 2011. The CDP report does not state the causes behind decreases in emissions. Decreases could be due to mitigation strategies, or changes in an organisation such as the sale of a component of the company, or outsourcing of some of the companies work.

The companies that experienced the largest percentage decreases in emissions from 2010-2011 were Group Five and Discovery Holdings, whose emissions decreased by 84% and 66% respectively. Wilson Bayley Holmes-Ovcon (44% reduction), Netcare (31% reduction), African Oxygen (30% reduction) and Growthpoint Properties (28% reduction) also experienced substantial decreases for the 2010-2011 period.  Out of these six, only Netcare and African Oxygen have had their emissions data verified by an independent third party.
