The Carbon Trust published on 22 September a report, based on analysis by McKinsey & Co., showing that tackling climate change can have a significant impact on company value in six sectors, worth a total of $7 trillion. The sectors are aluminium, automotive, oil and gas (exploration and production), oil and gas (refining), consumer electronics, building and beer. As much as 65% of company value it is claimed is at risk in some sectors if the shift to a low carbon economy is not now prioritised.
