The study looks at 60 of the most carbon-intensive extractive companies and at the extent and quality of disclosures they make in the management report and in the financial statements about the potential impact of climate change on their business. Clearly there are risks to the long-term viability of their activities which would impact their mineral or hydrocarbon reserves and the related infrastructure and leave them with ‘stranded’ assets. Overall the findings are that the reporting is not good enough and that annual reports lack clarity of and depth in climate change related disclosures.
