The Earthshot Prize Is Embracing the Idea of Positive Tipping Points

At a time when companies are racing to deliver commercial fusion energy and promising a new generation of geothermal wells across the U.S., three-wheel electric vehicles may not seem like the most exciting clean energy technology .

But in India, three-wheel vehicles are an essential part of daily transportation and account for up to a quarter of motorized trips in many cities.

The majority of new full-size passenger auto rickshaws sold in India are now electric, according to registration data , a striking milestone given that 10 years ago they were barely off the ground.

Initially, scaling took a mix of policy, infrastructure build out, and innovative financing; now, the market has taken on a life of its own.

“Once you cross 50%, electric becomes the dominant technology,” says Suman Mishra, the CEO of Mahindra Last Mile Mobility, a key player in the market.

The development underscores an idea that is gaining currency in some climate circles: sometimes technologies that matter most are not the futuristic breakthroughs waiting to scale but the familiar ones where adoption begins to reinforce itself.

That shift sits at the heart of a new framework the Earthshot Prize is using this year to evaluate climate solutions.

Rather than simply picking the climate solution with the most impressive technology, the judges looked for ways to recognize and advance “positive tipping points” that will unlock transformative changes beyond any individual company or project.

“We know exactly the things that we’re looking for to try to tip these global systems in the right direction,” says Jason Knauf, CEO of the Earthshot Prize.

The pattern is visible across the finalist list.

Mahindra Last Mile Mobility, one of this year’s Earthshot finalists announced on Sept.

18, has not just built affordable electric three-wheelers but also helped facilitate the infrastructure and policy necessary for them to take off.

Another finalist, the Zero Emission Maritime Buyers Alliance, or ZEMBA for short, has sought to coordinate demand for low-carbon shipping fuel from customers that ship goods.

And Yellowstone to Yukon restores habitat corridors across North America, which then unlocks feedbacks that restore the underlying ecological ecosystem.
