We must halve emissions and restore nature’s carbon
removal this decade


Global Optimism exists to precipitate transformational, sector-wide change. Achieving a zero emissions future is not a far-off challenge. It’s one we must get on track for now. Every scientific assessment shows that to meet the goal of net zero emissions by 2050, to keep global heating below 1.5°C, we must halve our emissions between 2020 and 2030.

Tackling the climate crisis is only possible when everyone, everywhere plays their part. We work with like-minded collectives from all sectors who are willing to invest in the choices required to be on this challenging – and life-affirming – journey.
