India's quiet electric revolution

Three-wheel auto rickshaws, essential to Indian cities, have shifted to electric. Most new ones sold are now electric, a dramatic change from a decade ago when the technology barely existed.

The 50 percent threshold

Once electric vehicles hit 50% market share, they become the dominant technology and adoption accelerates on its own. The market no longer needs heavy intervention to keep growing.

“Once you cross 50%, electric becomes the dominant technology.”

Earthshot's new framework

The Earthshot Prize now judges climate solutions by their ability to trigger positive tipping points, not just impressive technology. It looks for solutions that unlock transformative change across entire systems.

Three finalists show the pattern

Mahindra built affordable electric three-wheelers and the infrastructure for them. ZEMBA coordinates shipping demand for low-carbon fuel. Yellowstone to Yukon restores habitat corridors that trigger ecological recovery.

Reframing tipping points

Climate tipping points used to mean catastrophic thresholds like ice sheet collapse. Scientists now show positive tipping points exist too, where cheap energy or social movements trigger cascading benefits.

“The tipping point is where you have strong amplification within the system.”

Better bang for climate dollars

Tipping point solutions offer more climate impact per dollar spent. They identify investments that generate long-tail benefits, making them attractive to governments and institutional investors watching budgets.

A roadmap for climate investment

As climate impact becomes an important investment metric, positive tipping points offer a useful tool for allocating capital. The Earthshot finalists provide a starting point for identifying high-leverage opportunities.
