Layla Sawyer, secretaris

“Climate change is the defining challenge of our generation, and our ability to avoid a climate catastrophe will seal the fate of many generations to come.”

Layla is based in Brussels, working on integrating more renewable energy into the electricity system by influencing EU policy. She believes that we need to make our energy system more flexible, by shifting our electricity consumption to moments when there is a lot of renewable energy available. This will speed up the energy transition and make our current infrastructure as efficient as possible. Previously, she worked on various projects at Urgenda, Cordaid, Giro555. She is especially proud of co-organising the Climate Miles, a 600km+ march from Utrecht to Paris before COP21, supporting the Urgenda lawsuit, and helping set up the Grootouders voor het Klimaat.


Joost Hartog, penningmeester

“I believe in the power of diversity of actions and am a strong advocate for open movements that reach out to as many people as possible.”

Joost has a 40 years long history as an activist and campaigner in NGOs, as well as grass-roots organisations. Starting in the new social movements of the late seventies, he worked on the anti-apartheid struggle, for anti-racist organisations, but also for nature conservation and environmental causes. Joost lives and works in Amsterdam with partner and four grown-up children, and is an enthusiastic cyclist and climber.

Sumeyra Arslan

“As the current and future generations face the biggest challenges yet caused by climate change, I am honoured to join Fossielvrij NL in the fight for a better future and climate justice through corporate accountability.”Sumeyra Arslan, bestuurslid Fossielvrij NL

The burning desire to fight injustice worldwide has led Sumeyra to study Law. As a Kurdish Indigenous woman, she has witnessed her fair share of generational injustice. However, being born and raised in the Netherlands, she has privileges that most Indigenous People do not have. Using those privileges and as a legal expert, Sumeyra works on climate litigation with Milieudefensie (Friends of the Earth NL) and campaigns for a climate-related Advisory Opinion from the International Court of Justice. She has a strong background in human rights and climate change and developed expertise in corporate accountability, specifically in the fossil fuel industry, just transition, net zero commitments, the banking sector, and human rights violations related to the fossil fuel industry.
