By purchasing independently verified carbon offsets, customers support accredited environmental projects that either remove greenhouse gas emissions from the atmosphere (such as planting forests) or contribute towards emissions avoidance or reduction (such as providing more energy efficient cookstoves to communities that traditionally rely on open fire cooking methods). One unit of carbon offset represents one metric tonne of greenhouse gas emissions reduced or removed from the atmosphere.

Emissions from each Singapore Airlines (SIA) flight are calculated on a per-passenger basis. When you choose to make a voluntary contribution towards verified carbon offset projects for your flight, offset your share of emissions from your flight, the equivalent number of carbon offsets generated from these projects purchased will be retired by TEM. 

The SIA Group supports carbon offset projects that are verified in accordance with international standards by independent third-party auditors under the Verified Carbon Standard Program and the Gold Standard. These standards ensure that each project delivers real, measurable emissions reductions, which would not have occurred in a business-as-usual scenario should the project not be implemented. Each project is then issued carbon offsets, and each offset holds a unique serial number for traceability to prevent double accounting in the market. For instance, if the project demonstrated a reduction of 1,000 tonnes of emissions, they would be issued with 1,000 verified carbon offsets. Supported projects are also compliant or finalising compliance with strict criteria under the pilot phase of the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), which is governed by the International Civil Aviation Organization (ICAO). Carbon offsets purchased by customers are retired by TEM in the respective carbon registries where the projects are verified. This ensures that the offsets cannot be traded again.
