United States climate tenders

US climate money is concentrated in a few very large federal programmes plus a deep state layer. The Department of Energy dominates on dollar volume through OCED, ARPA-E and the Loan Programs Office; the EPA runs the environmental and climate-justice side; the USDA covers agriculture and forestry; and state agencies such as the California Energy Commission run their own solicitations on separate calendars. Listed below are the open climate tenders and public contracts in the United States that landscape produces, taken from each publisher's own notice and re-checked on every refresh.

Federal procurement runs through SAM.gov with registration required before bidding, and state and municipal buyers run separate portals. Set-aside categories for small and disadvantaged businesses shape a large share of the opportunity, and past-performance evidence weighs heavily in evaluation.

This page lists 4 open climate tenders and public contracts covering the United States, soonest deadline first. Every listing has been classified against the sustainability taxonomy rather than matched on keywords, and geographic coverage is read from the notice itself, so a programme open to the United States through a wider European or global scheme appears here too.

4 distinct buyers publish the calls on this page. Who is behind a call matters as much as what it funds: eligibility, reporting burden and the realistic timeline to a decision vary far more between buyers than between individual calls, so it is worth opening a listing before judging the programme.

The work on this page spans Biodiversity and Nature, Renewable Energy, Energy Efficiency, Air Quality, Waste Reduction. Narrowing to one of those is usually a better use of time than reading the whole list, because eligibility tends to follow the sector far more closely than it follows the country.

3 of these close within the next 30 days. Deadlines are taken from the source listing and re-checked on every refresh, but the publishing body remains the authority, so confirm against the official notice before you submit.
