Climate change is likely to become a major business driver over the next few decades as companies come under intense pressure to decarbonise their activities. There is general acknowledgement in government circles that the increase in global temperatures (above pre-industrial levels)must be limited to 2o C by 2100. This will entail a global reduction in CO2 emissions of 50% by 2050 (against
1990 levels), with some developed countries, such as the UK, already committed to an 80% reduction
over this period [Committee on Climate Change, 2008]
