We are Nesta. The UK’s innovation agency for social good. We confront challenges that affect millions of people, from inequality and ill-health to the climate crisis. Nesta wants to accelerate the UK’s transition to a low-carbon, productive economy. Our main focus is on decarbonising homes. We’d like to see the UK achieve a 28% reduction in household carbon emissions by 2030 (vs 2019 levels). We know that to reach this goal, at least five million households will need to switch to low-carbon heating in the next decade, and people will need to change how they use energy in their homes.
