The science behind it: halve emissions every decade
The Exponential Roadmap Initiative shows we can limit global warming to 1.5°C, if we halve global carbon emissions every decade, starting with the first halving by 2030 using solutions that already exist. Getting there takes all three parts of society working together: legislators setting the rules, producers switching to fossil-free solutions, and consumers like you and me cutting our footprint through lifestyle changes. ClimateHero focuses on that third part: empowering people to act.
