4.0 Protect Nature

Go from 6 gigatons of emissions to -1 gigatons by 2050.

We can cut 7 gigatons from the globe’s greenhouse gas emissions by ending deforestation, halting destructive fishing practices, and protecting more of our land and seas.

Restoring nature means setting aggressive but practical goals to protect 30 percent of the world’s forests, oceans, and lands by 2030, and half by 2050.

These goals take on added urgency from the prospect of a dangerous feedback loop. Global warming ignites parched trees into wildfires, which throw stored carbon into the atmosphere and drive temperatures even higher. 

This feedback loop needs to be switched off in a hurry. If it gets stuck on repeat, we’ll be staring at a runaway planetary disaster.
