The latest climate technology and sustainability developments on August 21, 2025, highlight mixed trends in funding, promising startups, and evolving policy landscapes:

Climate Tech Startups and Funding

•U.S. climate tech funding in H1 2025 rose 21% year-over-year, reaching $21.4 billion and accounting for 51% of global climate tech investment, despite broader global declines[1][4].

•Globally, climate tech investment dropped 19% in H1 2025 compared to 2024, with fewer but more selective deals and a shift toward non-dilutive funding like debt financing for infrastructure-heavy solutions[4].

•Climate Tech Partners secured over $50 million in funding, including a $30 million anchor investment from Australian Ethical and the Clean Energy Finance Corporation, focusing on grid, fuels, and adaptation technologies with corporate partners like Qantas and Airbus to validate demand and accelerate deployment[2].

•Europe’s climate tech funding slowed to $2.3 billion in Q1 2025, the lowest since 2020, reflecting market maturation and investor shifts toward AI and resilience, but innovation continues in key sectors like sustainable materials and low-carbon cement[5].

Notable Startups to Watch

•Trellis is curating a list of 25 early-stage climate tech startups across energy, carbon, transport, industry, and nature sectors, with applications recently closed for their 2025 showcase event in October[1].

•Promising startups include Sweden’s Material Exchange, which uses AI to reduce waste and emissions in fashion supply chains, and Cemvision, which cuts cement CO₂ emissions by up to 95% using recycled waste and electrified kilns[5].

Clean Energy and Environmental Innovations

•Innovations focus on decarbonizing heavy industry, sustainable sourcing, and nature-based solutions, supported by grants and open calls totaling up to €100,000 for projects in climate tech, energy access, low-emission transport, and biodiversity[3].

ESG Investing and Policy Context

•Despite political uncertainty and cuts to U.S. federal climate programs under the Trump administration, commercial partnerships and corporate demand for climate tech remain strong, supporting a resilient investment environment[4].

•Institutional investors increasingly favor collaborative funding models that integrate corporate customers early to ensure real-world impact and market adoption[2].

Carbon Impact Metrics

•Cemvision’s technology exemplifies significant carbon impact, achieving up to 95% reduction in CO₂ emissions compared to traditional cement production[5].

•Broader carbon impact metrics are tied to startups’ ability to scale solutions in energy, transport, and industry sectors, with Trellis emphasizing impact potential as a key selection criterion for its startup list[1].

In summary, while global climate tech funding faces headwinds, the U.S. market shows growth, innovative startups with strong carbon reduction potential are emerging, and collaborative investment models and policy resilience underpin ongoing progress in clean energy and sustainability innovation.
