As the Paris Agreement’s 2030 deadline for reversing the damage done to the planet looms, what can be done to save the Earth in less than a decade?
Enter the Earthshot Prize, founded by Prince William and one of the most ambitious attempts to turn back the clock on the climate crisis.
It’s a ten-year initiative that will reward five projects a year, each aiming to solve a distinct problem.
Fifteen finalists have been selected across five categories this first year, and judges include Sir David Attenborough, pop singer Shakira, actress Cate Blanchett and footballer Dani Alves.
Learn more with our guide, and via the new Earthshot docuseries available on BBCiplayer.
The winners (who’ll each get £1million to further their work) are announced on Sunday, in a London ceremony shown on BBC1.

Concerned about the health impacts of the toxic smoke given off by the burning piles of agricultural waste that blaze outside New Delhi, Vidyut Mohan found a solution.
His company, Takachar, has developed a portable machine that connects to farm machinery such as tractors, converting crop waste into fuel and fertiliser.
How it can make a difference: The machine reduces smoke emissions by up to 98%. If used in India, it could cut a billion tonnes of carbon dioxide a year.
The youngest finalist at just 14 years old, Vinisha Umashankar has invented a portable, solar-powered alternative to the charcoal-fuelled street irons that are used throughout India.
How it can make a difference: Reducing emissions and helping street vendors serve more customers, her invention could transform the way laundry is done across India.

As sewage systems become overwhelmed, Kenyan initiative Sanergy has developed dry toilets. Waste from homes and businesses is converted into fertiliser and sold to farmers.
How it can make a difference: Sanergy could be the answer to both waste crisis and food poverty.
Japanese start-up WOTA’s filtration system that converts 98% of waste water into drinking water.
How it can make a difference: It provides relief to typhoon victims.
FIX OUR CLIMATE
Invented by hydrogen company Enapter, the AEM electrolyser converts electricity into non-polluting hydrogen gas that can be used in cars, planes and heating.
How it can make a difference: The AEM electrolyser is a much-needed large-scale alternative to emission-spewing fossil fuels.
Invented by Olugbenga Olubanjo, the solar-powered capsules can be rented and returned for 50 cents a day, cutting energy costs by 30% and boosting local business. These capsules are powering 600 homes across Nigeria every month.
How it can make a difference: With the potential to be used globally, these capsules could solve electricity shortages in developing countries.
This Bangladeshi business has come up with sharing energy. Homes with solar panels can sell energy.
How it can make a difference: It reduces emissions and enables people make money from the sun.
