ET UK 100 reveals first Carbon Rankings results

The ET UK 100 Carbon Ranking, created by the Environmental Investment Organisation (EIO), has ranked the UK's biggest companies according to their greenhouse gas emissions and levels of transparency.

Insurers Amlin and financial services giant Aviva lead the list with carbon intensities of 1.21 and 1.36 respectively. BskyB, with 6.69, and energy services company AMEC, at 8.31, also ranked highly.

Complete disclosure of results was considered highly important in the EIO methodology. The top category was comprised only of companies that both publicly disclose and also independently verify their emissions data. The results were measured on the internationally recognised standard of Scope 1 and 2 emissions.

Some 66 per cent of companies among the ET UK 100 publically disclosed their data, but only half of those independently verified their reported emissions. BP and GlaxoSmithKline's data was defined as incomplete.

Sam Gill, operational director of the EIO, commented in the Belfast Telegraph, saying:"This shows the massive difference in attitude among Britain's top corporations.

"The rankings show that it’s less about what industry a company’s in and more about individual attitudes towards transparency. How can Shell and BP be at opposite ends of the table, or Lloyds and Standard Chartered?”

The ET UK 100 is the first in a series of Carbon Rankings, where the largest companies' worldwide will be covered through the forthcoming ET Global 800, Europe 300, North America 300, Asia-Pacific 300 and BRICS 100.
