What is Malaysia's grid emission factor for 2026?
There is no 2026 figure yet. The Energy Commission's latest factors apply to the year 2024: 0.740 kilograms of carbon dioxide equivalent (CO2e) per kilowatt hour in Peninsular Malaysia, 0.539 in Sabah and 0.199 in Sarawak. They are marked provisional, published on 23 February 2026.
What a grid emission factor is
It is like the fuel label on a car, but for electricity. It tells you how much greenhouse gas the power grid released for each unit of power it delivered. You multiply it by the kilowatt hours (kWh) on your bill.
The Energy Commission (Suruhanjaya Tenaga) publication defines it as the generation weighted average greenhouse gas emission per unit of electricity from all plants serving the grid, including renewable plants that may generate Renewable Energy Certificates (REC).
The three grids and the three years published
- 2024: Peninsular 0.740, Sabah 0.539, Sarawak 0.199
- 2023: Peninsular 0.760, Sabah 0.545, Sarawak 0.206
- 2022: Peninsular 0.769, Sabah 0.531, Sarawak 0.199
- The Commission prints these in gigagrams of CO2e per gigawatt hour. That is the same number as kilograms of CO2e per kWh, because 1 gigagram is 1,000,000 kilograms and 1 gigawatt hour is 1,000,000 kWh.
What the notes under the table say
- Peninsular and Sabah factors are calculated by the Energy Commission. Sarawak's comes from Sarawak Energy Berhad annual and sustainability reports.
- The figures use Tier 1 emission factors, and net generation is gross generation minus the plant's own use.
- Only main activity producers are counted. Fuel use and generation by other producers are not in the average.
- The 2022 Peninsular and Sabah factors were recalculated for updated data.
- The factor may not reflect the emission intensity of electricity unclaimed through RECs or other contractual instruments, because the renewable plants that may produce RECs are inside the average.
- The values are provisional. The publication says the figures are not expected to change materially, but they remain subject to final endorsement by the Government of Malaysia.
Which figure for a 2026 report (my reading)
The source gives no 2026 value, so I would use the 2024 factor for your region, label it as the latest published year, and swap it when the Commission publishes a newer one. Keep the same source each year and write down the publication date, so a buyer can trace it.
Use your own region. Peninsular, Sabah and Sarawak are published separately, and the 2024 Sarawak figure (0.199) is about 27 percent of the Peninsular one (0.740).
Same 500,000 kWh in two regions (example numbers)
- Peninsular Malaysia: 500,000 x 0.740 = 370,000 kilograms, so 370 tonnes of CO2e
- Sarawak: 500,000 x 0.199 = 99,500 kilograms, so 99.5 tonnes of CO2e
- Difference: 370 minus 99.5 = 270.5 tonnes of CO2e for the same electricity use
The 500,000 kWh is an example, not a real bill. Both factors are the 2024 provisional values.
What Senseible does here
Senseible reads fuel invoices and electricity bills into monthly records. For a Peninsular Malaysia bill it applies the factor above and labels the result with its source and year.
- Which Malaysian grid factor to use
- Malaysia renewable energy certificates and Scope 2
- Malaysia green electricity tariff and Scope 2
