Founded in Geneva in 2001, Covalence evaluates the environmental, social and governance (ESG) performance of thousands of companies around the world, with a focus on media analysis and social issues.

We provide professional investors with ESG ratings and data to monitor portfolios, define investment universes, track controversies, manage reputational risks and document positive impacts.

Our multi-source approach, combining human expertise and artificial intelligence, compares corporate disclosures with stakeholder perceptions. This approach also inspires confidence among academic researchers and non-profit organisations.

Our main differentiators are: pioneer, independent ESG rating agency; dynamic, granular news data documenting controversies, good practices and evolving sustainability issues; in-house AI capacities since 2014; greenwashing risk indicator; SDG mapping; expertise on social and political issues such as human rights, peace and democracy.

To produce ratings we compare ESG data publicly reported by companies (disclosure) to online narrative content reflecting the perception of stakeholders such as the media and NGOs (reputation). 

Covalence is a signatory of the Principles for Responsible Investment (PRI), a founding member of the European Association of Sustainability Rating Agencies, an institutional partner of Sustainable Finance Geneva (SFG), a founding member of Swiss Sustainable Finance, and a member of the Chamber of Social and Solidarity Economy in Geneva APRÈS-GE.
