InterClimate Network has a small but dedicated and passionate team. Find out more below about the people who drive our impact.

Our projects are managed by a group of freelance Associates, with international and UK experience including programme development and implementation, teaching, and facilitating learning with both teachers and students. We also access valuable input from several expert Advisors and obtain a range of support from a growing team of volunteers.

Our current Chair is James Streeter, who is a sustainable business leader. He is one of the first generation to actively pursue a career in sustainability and is keen to help others to enter this field. James leads our Board of Trustees, which consists of ten members responsible for the strategic direction of the charity.


  • James Streeter (Chair)

    James is a sustainable business leader and is one of the first generation to actively pursue a career in sustainability selecting his school and university studies to meet this goal.

    Upon graduating with his MSc in Environmental Management in 1992 he has seen sustainability grow enormously.   His work has taken him to many countries and some incredible environments including the Arctic, the Amazon rainforest and the deserts of the Middle East and North Africa, where he has seen both the vulnerabilities created by climate change and also the strong global commitment to take action. This is an intergenerational challenge and James is keen to inspire the next generation of young people into taking action, including creating opportunities for young people to get work experience and ultimately pursue a career in sustainability.
