This law requires the reporting of and the payment of a tax in relation to greenhouse gas emissions, and amends the Energy Conservation Act. 

The 2018 budget law stipulated that Singapore will impose a carbon tax entering into force in 2019. All facilities producing 25,000 tonnes or more of greenhouse gas emissions in a year will have to pay a carbon tax. The carbon tax will initially be $5 per tonne of greenhouse gas emissions from 2019 to 2023. The Government will review the carbon tax rate by 2023, with plans to increase it to between $10 and $15 per tonne of emissions by 2030.
