Our Top Open ESG Data Sources

The shift towards more open data models and collaborative efforts is not just a trend but a necessary evolution to meet the growing demands of regulatory bodies, investors, and the public for transparency and accountability in ESG performance. Historically, ESG providers have closely guarded their intellectual property. However, the rising demand for transparency and collaboration has led many to offer free data, showcasing the value of their methodologies. 

Simultaneously, consortium movements, such as The Open Group’s Open Footprint Forum and the International Building Performance and Data Initiative (IBPDI), aim to foster communication and alignment on how exactly to quantify and fill data gaps related to carbon footprinting and decarbonization. Here are some of our favorite open source datasets that you can leverage to inform ESG and sustainability-related projects:
