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.
uncertain
vehicles → race → 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.
asserted
vehicles → account → 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.
uncertain
they → sell → 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.
asserted
market → take → 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.
asserted
Mishra → cross → 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.
asserted
adoption → underscore → itself
That shift sits at the heart of a new framework the Earthshot Prize is using this year to evaluate climate solutions.
asserted
Prize → sit → 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.
asserted
that → pick → company
“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.
asserted
Knauf → know → Prize
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.
asserted
them → announce → infrastructure
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.
asserted
that → seek → goods
And Yellowstone to Yukon restores habitat corridors across North America, which then unlocks feedbacks that restore the underlying ecological ecosystem.
asserted
that → restore → ecosystem
The concept of climate tipping points entered the vernacular nearly two decades ago to describe some of the most alarming risks posed by climate change.
asserted
concept → enter → change
At the time, tipping points referred to the thresholds that, when crossed, would trigger a chain reaction of often irreversible damage—think of Antarctic ice sheet collapse leading to sea level rise or the destruction of the Amazon releasing stored carbon dioxide.
asserted
that → refer → dioxide
More recently, scientists have sought to reframe tipping points, showing that positive developments can have tipping points, too.
asserted
developments → seek → points
Cheap energy leads to a rewiring of economies.
asserted
energy → lead → economies
Social movements unlock widespread policy changes.
asserted
movements → unlock → changes
“The tipping point is where you have strong amplification within the system,” says Tim Lenton, a professor of the University of Exeter who has written seminal papers on the tipping points concept.
asserted
who → have → concept
The reframe comes at an important moment for the climate narrative.
asserted
reframe → come → narrative
With increasingly bleak climate news, positive tipping points offer grounded optimism about how things may change.
uncertain
things → offer → optimism
“We don’t think you can just leave people with the negatives and the warnings,” says Knauf.
asserted
Knauf → think → negatives
“We think we have a responsibility to show them” where positive action is possible.
asserted
action → think → responsibility
As companies cut costs and governments look for ways to trim public spending, tipping points offer a way to identify what Lenton describes as the best “bang for your buck” for climate investment dollars.
asserted
Lenton → cut → dollars
In some cases, that means supporting initiatives outside the typical wheelhouse of climate technology startups.
asserted
that → mean → startups
ZEMBA, for example, works with the customers who would like to reduce their shipping footprint with low-carbon fuel but cannot afford to do so on their own, thereby helping create a demand signal.
asserted
who → work → signal
That’s a coordinated effort that competitors rarely engage in.
asserted
competitors → ’ → that
“Once those markets are spinning, we will fade into the mist,” says Ingrid Irigoyen, the organization’s CEO.
asserted
Irigoyen → spin → mist
Such an approach makes sense for governments evaluating how they spend their public dollars.
asserted
they → make → dollars
It also makes sense for pension funds and institutional investors concerned with the long-term economic implications of climate change.
asserted
It → make → change
With relatively few dollars, certain investments will generate a long-tail of positive climate outcomes.
asserted
investments → generate → outcomes
For those interested, the Earthshot finalists may offer a useful place to start.
uncertain
finalists → offer → place
