London Climate Action Week opened this year with less appetite for pledges and more demand for proof. Patience has run out for announcements that never become deployments, exposing an uncomfortable truth: the field’s real bottleneck is no longer invention.
For years we poured money into a worthy task: building technologies to cut emissions and lift livelihoods. It worked. Solar-powered cold storage keeps a smallholder’s harvest from rotting; electric two- and three-wheelers cost less to run than petrol ones. In many cases, the hard engineering is behind us.
And yet almost none of it has reached the millions it was built for. The honest measure of the past decade is not how many technologies we proved, but how few crossed from pilot to mass market.
That gap is not an engineering problem. It is a problem of distribution, cost, and financing — and closing it demands as much innovation as the technology itself. This is the second form of innovation, and the one that is now underfunded.
The market left to its own devices will service the easy customer first. The communities most exposed to climate change — smallholder farmers, informal workers, women — are the ones markets and finance reach last. This is another critical role philanthropy plays in the transition: fostering deliberate design to serve the billions who have purchasing power but are otherwise missed.
Keep funding technological innovation — we will need breakthroughs for decades. But fund the other innovation just as hard: the financing, distribution, and business model innovations. Those are the ones that will put proven products into the hands of millions.
