Since its launch in 2023 Altérra has established itself as one of the world's most influential investors in sustainable private markets. It has established fund relationships with Brookfield, BlackRock, TPG, KKR and CIP, and a direct co-investment programme that spans infrastructure and private equity. It has partnered with Spanish bank BBVA and is on the lookout for additional, complementary LP partners to join its co-investment programme. It has also broken ground in terms of blended finance structures on a large scale.

In this episode,we welcome back His Excellency Majid Al Suwaidi, the CEO of Altérra, for an in-depth conversation. During a London Climate Action Week that took place amid a record-breaking heatwave, Al Suwaidi joined New Private Markets' Toby Mitchenall at PEI Group's London office, to discuss:

• How Altérra's co-investment activity has served as an effective manager evaluation tool;
• Establishing the co-investment vehicle, being on the receiving end of LP due diligence and the type of additional LPs Altérra wants to work with;
• How to frame returns expectations from a portfolio that spans private equity and infra assets;
• The evolution of the climate debate and how investors have or have not repositioned themselves;
• The next step: how Altérra wants to go further into the Global South by rethinking blended finance. On the concept of "first loss" capital: "Nobody wants to be the first loser, right? How do we change up the dynamic so that the first mover is actually the biggest winner?"

With all the discussion about promising VC-backed climate technology facing a "valley of death", what is actually needed to take these companies to scale? Building plants requires a lot of equity, a bit of senior debt, "but ultimately you need many more layers of the cap table", says Temple Fennell, co-founder and managing partner of Clean Energy Ventures. "You need insurance, you need wrappers of all types, you need EPC folks."

Fennell spoke to The New Private Markets Podcast on the sidelines of the Impact Investor Global Summit in London in May 2026. He is a veteran investor in climate technology, whose experience in sustainable investment was shaped by being part of the the Keller family office, which among other things converted its 3,500-acre farm to regenerative practices.

On the agenda:

• Clean Energy Ventures' expansion from the US to Europe;
• How clean tech companies can struggle when it comes to building plants;
• The specific project financing needs for these industrial companies;
• The recent glut of allocations to climate funds and how this is working through to returns.

When it comes to decarbonisation, investors have been spreading their capital too thinly across companies and technologies, says Stan Miranda, founder of the True North Institute and co-founder of All Aboard.

"We will not make the right investments if we don't face the reality of what's happening at the atmospheric level," says Miranda, "And for some reason or other investors in this space tend to back hope more than reality; and, as many people have said, hope is not a strategy here."

Miranda was among the speakers at the Impact Investor Global Summit in May this year in London, where this episode was recorded.

Miranda explains the rationale behind the All Aboard coalition, a group of climate tech investors working collaboratively in a bid to find and back the "winners" among climate tech companies.

"There's a philosophy in the climate investment world called 'all of the above', and the rationale behind it is that we don't know which technology is going to work, whether it's nuclear fusion or geothermal or clean hydrogen or various versions of carbon capture, so we need to invest in all of them. And that's the enemy of success here," says Miranda.

"We really need to talk to each other about what is really working commercially, what is not dependent upon policy support, and concentrate capital in those technologies. It won't be all of them, so it should be very focused and very collaborative, not 'all of the above'."
