Marion Denantes

In a nutshell, tell us about yourself.

I joined E Co. in 2014. Previously I was a consultant based in Brussels working on EU climate policy programme evaluations. I then did an MBA in the UK, the first specialized in carbon management, which brought me to the carbon market sector in a consulting company from Paris specialized in landfill gas to energy projects in developing countries. After the collapse of the carbon market, I spent some time in a think tank working on topics to accelerate the energy transition, and in a NGO to build a network of dedicated legislators from the developing world committed to solve climate change issues. At E Co. I enjoy my job because I work on a variety of projects (impact assessments, market assessments and project design) for diverse clients in the mitigation and adaptation areas all over the world, trying this way to make it a better place.

What are you most proud of?

Difficult to say anything other than my little boy!

What are your loves?

Honey, mozzarella and salmon

What are your hates?

When I travel and discover new places I hate seeing the wild landscape nature polluted by human activities and tourism.

What drives you to do this kind of work?

When I was younger, I used to live in a developing country close to nature. My first job experience was at UNEP in Nairobi during which I met Kofi Annan. This was a turning point and since then, I have decided to devote my professional life trying to help developing countries fight against climate change. I could not do anything else.

How do you see the world in 25 years?

I would like to see a world free of dependency on fossil fuels.

What is the hardest thing you’ve done in the last year?

I walked for 100km over 27 hours for Oxfam.
