Collect data on greenhouse gas emissions going back to 2010, and gross profits/margins for standardisation. This data can then be used to calculate a score for each company that shows whether they are emitting within their “fair share“ of global emissions, using a metric developed by the Center for Sustainable Organisations.

A live version of the context-based carbon metric is under development and when it is complete the scores will automatically be calculated for all companies where the required data is available.

You can see an earlier version of this metric on Wikirate here.
