The South African government has announced it will delay introducing a carbon tax until 2016. Finance Minister Pravin Gordhan said that a package of measures is needed to address climate change, and the delay will allow time for more consultation. In its budget review, the Treasury said a policy paper will be published soon -- proposals include the option for companies to reduce their carbon tax liability by using offsets. In the annual budget speech, Gordhan also said the government may impose new levies on mining companies to help fund the treatment of acid water seeping from disused gold mines.
