Our ideology

We're optimists.

We believe in the power of science to solve humanity's biggest problems and the power of markets to scale the benefits to everyone.

We believe the climate crisis is the single largest threat to humanity over the next century and decarbonisation the biggest opportunity to remake our world to be cleaner, greener and more equitable.
