Recent developments in climate technology and sustainability highlight significant funding initiatives, innovative startups, and evolving policy landscapes:

Climate Tech Startups and Funding

•A coalition of leading venture capital and private equity firms managing $60 billion in assets launched a $300 million fund called the "All Aboard Coalition" to support climate-tech startups transitioning from pilot to commercial stages. This fund targets rounds of $100–200 million to help build manufacturing facilities and scale proven technologies, addressing the critical "missing middle" funding gap[1][3].

•Spark Cleantech, a Paris-based startup, raised €30 million (~$32 million) in a Series A round to commercialize a methane plasmolysis process that produces clean hydrogen and solid carbon for industrial heat decarbonization. This technology enables heavy industries like steel and chemicals to significantly reduce CO₂ emissions by replacing fossil fuels with low-carbon hydrogen and capturing solid carbon as a byproduct[2].

•Other notable startups include Rondo Energy, which develops high-temperature thermal energy storage systems to decarbonize industrial heat (accounting for about 15% of global CO₂ emissions), and Dexmat, which innovates with carbon nanotube materials for energy and transportation applications. Dexmat has attracted backing from Shell Ventures and the U.S. Department of Energy, contributing to a collective $750 million raised by top climate tech startups in 2025[5][7].

•US climate tech funding reached $15.3 billion in the first half of 2025, with industrial decarbonization surging to 19.3% of total funding, reflecting strong investor interest in efficiency software, process electrification, and low-carbon materials despite reduced federal R&D support[4].

Clean Energy and Environmental Innovations

•Industrial decarbonization and grid modernization remain key investment areas, driven by AI-enhanced demand for reliable power and clean hydrogen solutions like those from Spark Cleantech[2][4].

•Innovations in carbon capture, such as direct air capture (DAC), face funding challenges, with US startups raising only $58 million in Q1 2025, down over 60% year-over-year, underscoring the importance of private funding initiatives like the All Aboard Coalition to fill gaps left by reduced public support[3].

ESG Investing and Climate Policy

•The shift from rapid acceleration to steadier progress in climate tech investing requires new standards and benchmarks for due diligence, which the All Aboard Coalition aims to establish, signaling market validation and encouraging further ESG-aligned investments[1].

•US federal climate spending has scaled back under the current administration, increasing reliance on private capital to sustain innovation and commercialization of climate technologies[3][4].

Key Metrics

•$300 million fund launched by top VCs for later-stage climate tech scaling[1][3].

•$32 million raised by Spark Cleantech for industrial decarbonization[2].

•$15.3 billion total US climate tech investment in H1 2025, with industrial decarbonization capturing 19.3%[4].

•$58 million raised by US DAC startups in Q1 2025, down 60% from prior year[3].

These developments reflect a maturing climate tech ecosystem focused on bridging funding gaps, scaling proven technologies, and advancing industrial decarbonization amid shifting policy and investment landscapes.
