The latest climate technology and sustainability developments as of November 28, 2025, highlight significant funding activity, innovation in clean energy and carbon reduction, and evolving climate policy support.

Climate Tech Startups and Funding

•In 2025, U.S. climate tech investments reached $15.3 billion in the first half, up from $11.4 billion in the same period in 2024. The sector now accounts for 13.3% of total funding, with a notable shift toward later-stage deals (Series C and D rounds up 33.3%) and industrial decarbonization startups receiving 19.3% of funding, nearly doubling since 2020[2].

•Notable startups include Pachama, which raised $79.3 million in Series B funding to use AI and remote sensing for forest carbon capture and carbon credit markets[5]. Climavision secured $100 million in Series A to develop advanced weather radar and satellite networks for climate prediction[5].

•GreenFi (Climateforce Pte Ltd.) raised $2 million in seed funding led by Transition VC, focusing on ESG, AI risk management, and sustainability tech with a mission to offset 40 million tons of carbon emissions[6].

•Other startups with significant funding include Bolt Threads ($406.4 million), BlocPower ($262.6 million), and South Pole ($99.3 million), working on biotechnology, energy efficiency, and carbon offset projects respectively[4].

•Venture For ClimateTech continues to support early-stage innovators with up to $50,000 in non-dilutive funding and hands-on acceleration, focusing on decarbonizing buildings, transportation, grid, and industry sectors, with applications for their 2025 cohort open until March 12, 2025[1].

Clean Energy and Industrial Decarbonization

•Energy generation and grid modernization remain the largest funding recipients (33.2%), driven by AI demand for reliable power and infrastructure upgrades[2].

•Industrial decarbonization is surging with investments in efficiency software, process electrification, waste-heat recovery, and low-carbon materials, though capital-intensive breakthroughs face funding challenges due to reduced federal R&D support[2].

ESG Investing and Environmental Innovations

•ESG and sustainability tech are growing investment areas, exemplified by GreenFi’s AI-driven ESG risk management platform[6].

•Carbon tracking and offsetting companies like Minimum ($5.3 million raised) and Pachama are advancing environmental innovation through technology-enabled carbon impact metrics[4][5].

Climate Policy and Accelerator Programs

•While government-backed climate tech funding has slowed, private investment and accelerator programs like Venture For ClimateTech are filling gaps by supporting startups with funding, mentorship, and pilot opportunities[1][2].

•Policy details emphasize support for decarbonization in New York and other regions, with a focus on community-positive solutions and scaling climate tech innovations[1].

In summary, 2025 sees robust private investment in climate tech startups, especially in industrial decarbonization and clean energy infrastructure, supported by accelerators and ESG-focused innovations. Funding rounds are larger and later-stage, reflecting maturing technologies and market readiness, while policy and accelerator programs continue to nurture early-stage innovation with targeted funding and support[1][2][4][5][6].
