The 2020 Woman’s Hour Power List seeks to highlight the work done by women committed to making the world more sustainable.
Ms Lucas, the former leader of the Green Party, is followed by environmental lawyer Farhana Yamin, clean air campaigner Rosamund Kissi-Debrah, young birder and environmentalist Mya-Rose Craig otherwise known as Birdgirl, and Sophie Howe, the Future Generations Commissioner for Wales.
Lucy Siegle, a journalist who sat on this year’s panel, said Ms Lucas held “power to account” and her impact would increase yet further as the climate crisis escalates.
She said: “The judges recognised that Caroline is the politician of our generation who almost uniquely uses environmental logic to make her decisions.
“She is able to explain scientific evidence in clear and impactful terms, is creative on policy and very alive to ideas, fearless in holding power to account and has unparalleled experience.
“Immediately recognisable as a key moderniser of the green movement (she was elected to the Green Party in 1999) she is one of just a few recognised and trusted voices on the environment.
“As judges we felt that as the dual crisis in nature and climate becomes ever more immediate, her influence, expertise and experience should see her already extensive influence continue to grow.”
