Marion Verles


Marion Verles is a climate and sustainable development entrepreneur who has dedicated her career to the transformation of our economic system, through the redefinition of value.   Her deep belief is that ‘intelligent’ impact measurement can transform our economic and financial systems. 

This is why Marion co-founded SustainCERT in 2018 – she identified that third-party expert verification of impact measurement is key to driving credibility in environmental markets, corporate sustainability and sustainable finance.  In 2023 SustainCERT will launch the world’s first digital verification platform.

Marion was previously CEO of the Gold Standard Foundation, a leading carbon market standard, where she led the launch of the Gold Standard for the Global Goals (GS4GG) as well as the Value Change Program. During this time she also co-founded the Sustainable Development Initiative and the Climate Ledger Initiative.

Before joining Gold Standard, Marion spent seven years in Asia where she founded the Nexus Carbon for Development, a successful co-operative of development organizations looking to scale climate mitigation programs through results-based finance.

Marion is a lifelong learner. She holds a Masters in European Business from EDHEC business school, a diploma in Public Administration from Ecole Nationale d’Administration and is currently studying a Bachelor in Psychology to gain insights into the inner motivations that can drive people to adopt sustainable lifestyles. 

Marion is particularly passionate about net zero corporate climate action, leveraging technology to drive impact at scale, the innovation and transformation of impact verification, new economy leadership and climate entrepreneurship.
