AI Narrative Summary
The Isle of Man has achieved a modest 3.8% reduction in greenhouse gas emissions since the 2018 baseline year, falling from 596,606 to 573,880 tCO2e in 2023.
Energy supply remains the largest emission sector at 43.6%, followed by transport (27.6%) and agriculture (18.3%). The shift from local power generation to interconnector imports has increased the energy supply share from 29% in 1990 to 44% in 2023.
At the current rate of reduction (4,545 tCO2e/year), the projected 2030 emissions would be approximately 542,064 tCO2e. This exceeds the 2030 interim target of 387,794 tCO2e, indicating that accelerated action is needed.
LULUCF (land use, land-use change, and forestry) provides a significant carbon sink of approximately 83,500 tCO2e annually, offsetting roughly 14.6% of gross emissions.
CO2 dominates the gas mix at 77.7%, with methane (CH4) at 14.5% primarily from agriculture, nitrous oxide (N2O) at 5.6%, and HFCs at 2.2%.
