Grants to go green
Co-funding for energy-efficient equipment and sustainability upgrades.
3R Fund · National Environment Agency (NEA)
3R Fund (Reduce, Reuse, Recycle)
NEA co-funds up to 80% of projects that reduce or recycle waste, capped at S$1 million, with the payout pegged to how many tonnes of waste you actually divert. Open to companies and organisations of any type, but the project must cut at least 100 tonnes of waste over its duration.
EEG · Enterprise Singapore / NEA
Energy Efficiency Grant
Co-funds up to 70% of pre-approved energy-efficient equipment (LED, aircon, refrigeration, cooking equipment and more) for SMEs in supported sectors like F&B, manufacturing, and retail.
REG(E) · Singapore Economic Development Board (EDB)
Resource Efficiency Grant for Emissions (REG(E))
EDB co-funds up to 50% of projects in manufacturing facilities and data centres that measurably cut carbon, such as energy-efficiency retrofits, non-CO2 greenhouse gas reduction or flare gas recovery. The scheme is open until end-FY2030 and the grant is sized by the carbon abatement your project actually delivers.
WEF · PUB, Singapore's National Water Agency
Water Efficiency Fund
PUB co-funds businesses to audit, pilot and implement water-saving measures, from a 70%-funded water audit up to S$5 million for a full-scale water recycling plant. Aimed at heavier water users (from 1,000 cubic metres a month), it pays you either per cubic metre of water saved or a share of capital cost, whichever is lower.

Common questions
Which Singapore grants help businesses go green?
4 schemes are listed here, including 3R Fund, EEG, REG(E), WEF. Each entry shows the support rate, the cap, who qualifies and the official source.
Can I combine more than one grant?
Sometimes, but never for the same cost. Most application forms ask whether you are claiming any other government support for the same expenses, and double funding is a common reason for rejection or clawback.
