One Earth is a philanthropic organisation working to accelerate collective action to limit global average temperature rise to 1.5°C. The solutions for the climate crisis already exist, and the latest science shows we can achieve the 1.5°C goal through three pillars of action – a shift to 100% renewable energy by 2050, protection and restoration of half of the world’s lands and oceans, and a transition to regenerative, climate-friendly agriculture. To achieve these goals, we must rapidly scale philanthropic capital to meet critical funding gaps over the coming decade.
