Companies wanting to demonstrate corporate social responsibility by being a member of the FTSE4Good stock market index will be forced to show they are reducing their carbon emissions.
About a quarter of the energy-intensive users in the FTSE4Good are heading for removal unless they change their ways, according to the index's organisers.
Oil companies, airlines and mining firms will be told today they must deliver a 2.5% per annum reduction in carbon emissions and publish specific climate-change policies for which their boards must take direct responsibility under a first phase of the new initiative that will gradually be rolled out for all members.
