We donate £2 for every member

Every time someone signs up to Bulb, we donate £2 to Bulb Foundation to stick up for the planet and speed up the transition to a low-carbon economy.

Bulb Foundation is a registered charity founded by Bulb to tackle the climate crisis head on.

The world needs big, systemic changes

Bulb Foundation funds low-carbon ideas and initiatives, and connects pioneering organisations that focus on ending the climate crisis. 

It helps people already dealing with the effects of the crisis by amplifying their voices and driving real changes to government policy around the world.
