The results, which were published yesterday (February 16) at BASE in London, were compiled by the Environmental Investment Organisation (EIO), a non-profit research body.

Leading the top 100 are insurers Amlin and financial services giant Aviva, with carbon intensities of 1.21 and 1.36 respectively (MtCO2e/$M turnover).

Others ranked highly are British broadcasting giants BSkyB, whose intensity of 6.69 place it 4th, followed by energy services company AMEC, at 8.31.

The worst performer of the UK’s biggest 100 companies is Randgold, a gold-mining company operating primarily in West Africa.

The EIO has adopted a strict methodology based on complete disclosure of Scope 1 and 2 emissions according to the Greenhouse Gas Protocol, the internationally recognised standard for emission reporting.

Only companies that publicly disclose and also independently verify their emissions data made it into the top category.

Among the ET UK 100 companies, although 66% publicly disclose their data, only half of those are also independently verifying their reported emissions.

With the exception of BP and GlaxoSmithKline, whose data was defined as incomplete, all companies with a market value over $100BIL publicly disclose their complete emissions data.

EIO operational director, Sam Gill, said “Given that each company listed in the ET UK 100 is one of the biggest in Britain, if not the world, keeping this information out of the public domain is no longer excusable.”
