Here is a summary of the latest climate technology and sustainability developments as of August 28, 2025, focusing on climate tech startups, clean energy, ESG investing, climate policy, and environmental innovations, including funding and impact metrics:

Climate Tech Startups and Funding

•U.S. climate tech funding in the first half of 2025 increased by 21% compared to the same period in 2024, despite global investment in climate tech dropping 19% in the first half of 2025 compared to 2024. The U.S. accounted for 51% of global climate tech funding, totaling $21.4 billion, with projections for 12% growth in 2025[1][4].

•Equatic, a climate tech startup based in Los Angeles and Singapore, raised $11.6 million in Series A funding on August 13, 2025. Equatic’s patented seawater electrolysis technology simultaneously captures CO₂ and produces green hydrogen. The funds will support scaling a 100,000-tonne carbon removal facility and commercialization. Investors include Catalytic Capital for Climate and Health (C3H) and Kibo Invest[3].

•Europe’s climate tech funding has slowed, with Q1 2025 funding at $2.3 billion, the lowest since 2020, reflecting market maturity and shifting investor focus. Notable startups include Material Exchange (AI-powered sustainable material sourcing for fashion) and Cemvision (cement production using recycled waste and electrified kilns, reducing emissions by up to 95%)[5].

•Trellis is curating a list of 25 early-stage climate tech startups to watch in 2025 across five sectors: energy, carbon, transport, industry, and nature. The application deadline was August 5, with finalists pitching in October 2025 to sustainability leaders and investors[1].

Clean Energy and Carbon Impact Innovations

•Equatic’s technology is notable for combining carbon removal with green hydrogen production, aiming for large-scale impact by removing 100,000 tonnes of CO₂ annually per facility[3].

•Cemvision’s innovation in cement production could reduce emissions by up to 95%, addressing a major industrial source of carbon emissions[5].

ESG Investing and Market Trends

•Despite a global dip in climate tech investment, non-dilutive funding (e.g., debt financing) is rising, signaling growing confidence in commercially viable climate tech solutions with clear revenue models[4].

•The U.S. market remains resilient despite policy uncertainty, with increasing commercial partnerships between technology providers and buyers[4].

Climate Policy and Environmental Innovations

•The Trump administration’s cuts to key climate tech funding programs, including the Loan Programs Office, have created uncertainty, but the market has shown resilience so far[4].

•Numerous grant and funding opportunities continue to support climate, biodiversity, and food systems innovation globally, including agroforestry, aquaculture, circular economy pilots, and biotech for resilient crops, with 94 opportunities listed as of late July 2025[2].
