Climate change is society’s greatest challenge.

Break it down into wedges of action, and stack them into your own decarbonisation pathways.

Based on a new peer-reviewed paper in Science.

Wedges are building blocks of climate action

Each wedge delivers the same effect, cutting 30 billion tonnes of carbon over the next 30 years.

You can compare strategies on a level playing field, and stack wedges together to bend the emissions curve.

20 wedges can limit global warming to 1.5°C.

36 strategies can deliver wedges

There are actions involving electricity, industry, land & food, travel, and buildings.

We show how rapidly each strategy must be deploed to deliver a wedge. They all require enormous effort, but all are acheivable.

There are over six trillion ways to hit 20 wedges, which will you choose?
