A clear and transparent scoring method

Process and Scoring
The climate data collected is then analysed by our expert teams to establish a score that provides clarity on your carbon emissions.
Our scoring system rates the seriousness of a company's climate commitment.
What if my company receives a bad rating?
No need to panic! Greenly re-evaluate the companies that contact us to update their scoring. To do this, we ask for documents attesting to the seriousness of your commitment. Once validated by our experts, the score can be updated to reflect this.Contact our experts
