About ESGGen is on a mission to make Environment and Social Governance (ESG) reporting accessible and meaningful for SMEs and Startups. As global governments and regulators emphasise things like net-zero CO2 emissions, gender pay gap, diversity, and sustainable business practices, companies of all sizes must take action to transform the way they do business.

Esggen has developed a proprietary and unique methodology to assess the ESG impact using only information sets and data easily and readily available within all SMEs. This methodology was developed by Marc Lepere (Founder & Chief Science Officer) as part of his PhD research at King’s College London and refined in collaboration with Edinburgh University and RedRice Ventures in partnership with the British Business Bank.
