Over the last 2 weeks we have featured the 15 finalists in the Earthshot prize, an initiative to highlight and award projects designed to conserve and sustain natural environments, and improve our lives in ways that are sensitive to issues such as climate change and biodiversity loss. Here we discuss this year’s winning projects and what future investment could mean for them.

There are five prize categories with a million pounds up for grabs in each.

Protect and restore nature.
Clean our air.
