The Big Green Challenge is NESTA’s £1 million challenge prize designed to stimulate and support community-led responses to climate change.

Through the Big Green Challenge, we aim to uncover what support these communities need to transform their bright ideas into viable solutions that will improve all of our lives.

In early 2008, 355 groups came forward with a wide range of imaginative and practical ideas for reducing CO2 emissions in their communities.

We selected 100 of the most promising groups, who received support from the Big Green Challenge team to develop their ideas into detailed plans. From this group, we shortlisted ten finalists who are now putting their ideas into practice to compete for the £1 million prize.
