10:10 is an organisataion that works with companies, schools and people to get them to reduce their carbon emissions by 10%.
I can’t quite untangle the people involved as the 10:10 website says it was founded by Franny Amstrong who was the director of the climate change blockbuster The Age of Stupid. They also work with Lizzie Gillett, featured in this video below, who also worked on The Age of Stupid.
