Jersey’s greenhouse gas emissions fell by 48% between 1990 and 2023, but there was no reduction between 2022 and 2023.
The latest dataset, which estimates emissions from a wide range of activities, found Jersey emitted 357,626 tonnes of greenhouse gases in 2023.
Transport and heating buildings continue to be the biggest causes of Jersey’s emissions; with transport accounting for 43% of Jersey’s total emissions, and car fuel journeys specifically accounting for 26%. Heating and cooling homes and businesses account for almost 33% of Jersey’s total emissions.
The figures in the inventory are produced by independent organisation, Aether. The inventory provides estimates for historical emissions of greenhouse gases from 1990 until the most recent submission year, minus two. Therefore the 2025 inventory covers the period 1990 to 2023.
