Carbon Ranking of Companies - by the Environmental Investment Organization


Ranking overview

The purpose of the ET (Environmental Tracking) Carbon Ranking is to provide information on a company's greenhouse gas emissions intensity as well as its level of disclosure and verification.

The aim of the ET Carbon Ranking is to encourage increasingly higher levels of disclosure and verification while incentivising corporate greenhouse gas (GHG) emissions reduction on a global scale.

From 2011 the ranking will be based on a greenhouse gas emissions intensity metric relative to a company’s size, with companies ranked regardless of industry or sector.

In order for this to be achieved, the Ranking must be based on externally verified emissions data of what are known as Scope 1, 2 and 3 emissions. When correctly applied, these three Scopes, based on the definitions provided by the Greenhouse Gas Protocol (GHG) standard, cover the entire range of each company's emissions.

The GHG protocol provides a full explanation of the methods companies use to cover these different types of direct (Scope 1) and indirect (Scope 2 and 3) emissions.

A combined Scope 1, 2 and 3 total, when externally verified to an agreed international standard, is a solid basis for a Carbon Ranking.
Treatment of Scope 3 for 2011 ET Carbon Ranking

While the ET Carbon Rankings are designed to be based on companies’ GHG emissions across the whole value chain, the EIO has taken the decision not to factor Scope 3 data into its intensity calculations for 2011. Instead it will display Scope 3 data in terms of numbers of Scope 3 categories disclosed in order to allow companies time to integrate the new GHG protocol Scope 3 Accounting and Reporting Standard.
