Net zero and decarbonisation tenders
Net zero and decarbonisation tenders are the broadest family on this site, and among the most numerous. They run from strategy work, such as a net zero roadmap for a city, a hospital trust or a national industry, to delivery: decarbonising a heating system, a vehicle fleet, a port, a district or an industrial process. Development banks add a third group, funding decarbonisation studies and investment programmes in emerging economies.
Because the range is so wide, read the scope line before anything else. A roadmap tender wants carbon accounting, abatement cost analysis and a costed pathway; a building or estate tender wants engineering design and project management; an industrial decarbonisation study wants process expertise. Many buyers now ask that any decarbonisation plan be tied to a recognised framework or target, and that it sets out interim milestones they can report against.
This page lists open tenders that mention net zero, decarbonisation or carbon neutral in their text. It is built for climate strategy consultancies, energy and engineering firms and the specialists who take public bodies from target to delivery.
54 open tenders match this topic today, across 6 countries on the first page. 12 of those shown close within 30 days. Recently closed notices are listed after the open ones. Deadlines come from the source notice; confirm against the official document before you submit.

Frequently asked
What is a net zero roadmap tender?
A commission to set out how an organisation or area will reach net zero emissions: a baseline, a target year, costed reduction measures and interim milestones.
Are building and fleet projects included?
Yes, where the notice describes them as decarbonisation or net zero work. Narrower pages cover heat pumps, energy audits and electric vehicle charging.
Why so many listings?
Net zero and decarbonisation are now the stated purpose of a large share of public energy and infrastructure spending, so the terms appear in many notices.
