Only 16 of Britain’s top 100 listed companies have met the government’s guidelines on greenhouse-gas emissions. As a result, almost 200m tonnes of CO2 is estimated to be missing from the annual reports of FTSE 100 companies.The figure is more than the entire annual emissions of Pakistan and Greece combined.
Andrew Pendleton, the climate change analyst who wrote the report, said: "The calculations we have made relate to basics, like office lighting, but take no account of investment or supply chains, which are much bigger [emissions] areas. The figures that companies currently declare are such a mess that it is impossible to calculate their total emissions."
