Microsoft co-founder Bill Gates on Thursday urged investors to get behind cutting-edge climate technologies he says would drive a “green industrial revolution” and a next wave of global prosperity.
Over three days in an upmarket London venue, Gates showcased more than 100 companies making ground on cutting planet-heating emissions from carbon-intensive sectors most responsible for climate change.
Gates is a firm believer in the power of innovation to drive breakthroughs in heavily polluting industries like manufacturing, energy and transport.
He is the single largest investor in a fund he established in 2015 that has ploughed around $2.2 billion into early-stage technologies like low-carbon cement, zero-emissions aviation and sustainable building materials.
But in the quest to deploy these technologies more quickly at scale, Gates is seeking to widen the investor base from venture capitalists to pension and sovereign wealth funds.
Many of the innovations he has bankrolled are still at the lab level and not making a dent on the heat-trapping gases that drive global warming, let alone a return on investment.
Critics say climate technology is a costly distraction when deep reductions in emissions are needed today, as well as money to help the developing world cope with climate change.
Gates acknowledged that innovation alone would not solve the problem, but said there were several reasons to be optimistic.
Some of these companies are already rolling out innovations, he said, while others are showing great progress in short time.
“I think the clock is moving forward because of human ingenuity,” he told reporters at the close of his Breakthrough Energy summit at a 19th-century dockyard in London.
“I do think we can provide all services that mankind wants with zero emissions without making the cost of those services higher… I don’t think I am crazy to be optimistic.”
Less than a decade ago, Gates said, there was very little investor interest in climate technologies.
He raised an initial $1 billion with other ultra-wealthy investors including Amazon’s Jeff Bezos and Alibaba’s Jack Ma, and their first summit in 2022 attracted a few hundred attendees.
But investors beyond deep-pocketed philanthropists are starting to pay attention to climate start-ups long deemed too risky a bet, industry figures show.
At the London event, Gates brought together around 1,500 executives from banks, state-backed investment funds and major businesses.
In one pavilion, potential investors inspected hydrogen-electric aircraft engines designed by ZeroAvia, hunks of low-carbon steel manufactured by Boston Metal, and an enormous magnet used by Commonwealth Fusion Systems to test fusion power.
Source, a company that uses a “hydropanel” to harvest water from vapour in the atmosphere, quenched thirsts on a hot summer’s night.
The fast rise in investor interest was obvious and understandable, said Tim Heidel, CEO at Veir, a company backed by Gates that is exploring high-temperature conduction to improve electricity transmission.
