📣Methane causes ~30% of global warming, and even with emissions reductions, a gap will remain by 2050. Biological methane removal (bioMR) is one of the most promising frontiers for closing that gap. With @sparkclimate, we convened 30 experts to map the highest-leverage research opportunities, resulting in 22 problem statements. #ClimateBiotech #BioMethaneRemoval homeworld.bio/blog/homeworld…

⚡️After 30 episodes, Dan Goodwin hosts his final episode of The Climate Biotech Podcast, reflecting on lessons learned and passing the mic to incoming Executive Director, @PaulReginato. #ClimateBiotech #TheClimateBiotechPodcast 🎧 Apple/Spotify: homeworld.bio/podcast/

🌱 The Homeworld 2025 Annual Impact Report is out! When we connect researchers to high-leverage problems, the right collaborators, and funding resources, they respond with creativity and rigor. See what we've built together. #ClimateBiotech #AnnualReport homeworld.bio/blog/homeworld…

📣 On the latest episode of the Climate Biotech Podcast, hear how @sandlab is building BIOME Consortia to take biology from thousands to billions of strains for applications. 🎧 Apple: bit.ly/4pZniVH 🎧 Spotify: bit.ly/4qSvhFy #ClimateBiotech #ClimateBiotechPodcast

This marks the execution of our first true Roadmap-Ignite-Fund-Synthesize (RIFS) cycle and the results exceeded our expectations. Our funding hypothesis was simple: surfacing important problems would be mutually reinforcing to funding solutions. By facilitating collaborative identification of problems that connect researchers to funding we're accelerating research in climate biotech. Thanks to Garden Grant co-funders @SparkClimate and @granthamcsf, and to Quadrature Climate Foundation for or making this possible through programmatic and regranting support.

Excited to share that we're deploying ~$1.4M to 11 groundbreaking teams through our Greenhouse Gas Removal Garden Grants! Funded projects span from methane-eating microbes on tree surfaces to bio-enhanced rock weathering. See our announcement: homeworld.bio/blog/announcin…

@pnwclimateweek is here! Seattle based folks - join us Tues, July 22 (3–4:30pm) at CoLabs rooftop for a panel + social on how biotech can help solve climate challenges. Hear from scientists + founders at Decycle Bio, LanzaTech, UW & more. RSVP: lu.ma/o9re0y84

Plastic → perfume? On the new Climate Biotech Podcast, @cxarramirez shares how his lab uses Antarctic enzymes to break down plastic at low temps and turn it into high value products, like fragrances, that actually fit Latin America's market needs. 🎧 podcasts.apple.com/us/podcast/the…

Why share problems openly? Homeworld identified two critical gaps in the climate biotech space: risk-tolerant funding and limited interaction and collaboration among teams. Garden Grants addresses both issues by spotlighting the most urgent challenges and supporting the bold approaches researchers propose to solve them.

📢 Big news from Homeworld: We’ve published over 50 problem statements from proposals submitted to our second Garden Grants program, focused on greenhouse gas removal.

◾️Want to help shape this? We’re deciding whether to extend this AI-based TEA tool more generally. If you think a low-cost, AI-driven TEA can speed up your biotech journey, please let us know. Your feedback will guide us on whether to invest more resources into making this tool widely accessible.

Every technology starts with a techno-economic analysis (TEA) - a basic financial model that bridges ideas with practical feasibility. More than the financial sense, it shows that you (the innovator) knows HOW your invention would become something in the real world.

For more problem statements in biological GHGR, check out our problem statement repository: (homeworld.bio/research/probl…).

Solving these challenges would unlock new approaches to biologically-enhanced enhanced rock weathering, potentially making it a more scalable, efficient, and cost-effective method for atmospheric carbon dioxide removal.

During the application window for Garden Grants, we will share problem statements describing challenges in biological GHGR. Today’s focus: Using microbes to speed up mineral weathering for carbon removal.
