Update: 🇺🇸 The US elections and climate tech investing

Donald Trump has been elected the 47th president of the United States, and Republicans have gained the majority in the Senate. While there are many uncertainties about the consequences of these results, we expect the impact to be significant on numerous critical issues, including the energy transition.

Many people are working through what consequences might be for climate tech and climate investing. A lot still depends on the composition of the House of Representatives.

While the mood at Carbon Equity was not the brightest yesterday, one person in our team summarized our resolve succinctly:

“Today really highlights that the fight against climate change can’t depend on activism and policymaking alone. We need climate tech and other market-based solutions with clear economic benefit to ensure political shifts can’t come with this high risk for progress.”

We at Carbon Equity are closely monitoring new analyses coming out and what all of this means for climate tech and climate investing. We will share our synthesis of the best insights with you as soon as we can.

In the meantime, I would like to share with you some of the inspiring companies scaling up fast and shaking up industries that have long been stuck in their old, carbon-heavy ways. They embody progress and provide some much-needed hope. 😉

🦄 9 climate unicorns leading the transition to a low-carbon future

It’s crystal clear to me that climate tech is the place to be for both impact and returns. Sure, 2024 saw a funding drop compared to the peak years. Climate-tech VC and growth equity funding totaled $11.9 billion in 1H24, a 20% drop versus 1H23, according to CTVC.

However, in our recent whitepaper, we argued that there are powerful economic drivers pushing climate tech into the mainstream far beyond its niche roots. From declining cost curves to the heightened focus on energy security driven by geopolitical competition—and individuals simply caring more about sustainability in their work and daily lives—climate tech’s growth is driven by forces that run deeper than economic cycles. This isn’t a fleeting trend, climate tech will continue to gain momentum.

Our mission at Carbon Equity remains clear: fund the game-changers. Help them become the large companies with the power to really slash emissions and transform our industries.

Here’s a sneak peek of the climate tech unicorns we’re proud to support:

Global emissions set to peak in 2024 thanks to EVs, clean energy

New research from the independent research firm DNV shows global emissions are now expected to peak in 2024 and then start to decline. The rapid adoption of clean technologies like electric vehicles, solar power, and advanced battery storage has put the world on track to cut greenhouse gas emissions in half by 2050. Although it’s a milestone, that’s obviously still far from reaching our critical net zero goals.

Why the time for grid tech innovation is now

There's a big opportunity to build the next big business in grid technology. The need is increasing by the day and with an abundance of public investing and over 30 billion VC funding only in 2020, now is the time to build! However, energy resilience challenges are complex and multifaceted. Meaning there are several topics funds should take into account: chasing the right capital (debt vs. equity), varying customers and sales cycles, and the importance of partnerships just to name a few.

Unlocking Arkansas’ hidden treasure: USGS uses machine learning to show large lithium supply
