Managers from carbon intensive companies are holding off on long term emissions strategies because of uncertainty around regulations and policies, new research finds.
For three years, carbon emissions from fossil fuels have grown little or not at all, opening a window of opportunity to halt climate change.
Many models used by policy-makers suggest we'll have to remove CO2 from the atmosphere - but if we can't, we have to get much more serious about cutting emissions.
