Singapore Carbon Pricing Act
Singapore's carbon tax law, charging large emitters per tonne of greenhouse gas with a rate scheduled to rise sharply toward 2030.
Definition
Singapore's Carbon Pricing Act, enacted in 2018 and in force since 2019, imposes a carbon tax on industrial facilities emitting at least 25,000 tonnes of greenhouse gases annually. Introduced at five Singapore dollars per tonne, the legislated trajectory raises the rate to S$25 in 2024–25 and S$45 in 2026–27, with a view to S$50–80 by 2030, and allows partial use of high-quality international carbon credits from 2024.

Overview
What it means
Southeast Asia's first carbon tax converts Singapore's climate pledge into a rising, facility-level cost of emissions.
How it is used
Refineries and power generators file emissions reports and pay the levy; firms plan abatement and credit strategies against the rising schedule.
Why it matters
It is the reference carbon-pricing design for the region — simple, economy-wide upstream coverage with a credible escalating price path.
