What is Sri Lanka's pathway to limit global warming to 1.5°C?
Transport
Sri Lanka relies heavily on road transport, accounting for 95% of passenger transport and 97.5% of freight transport.1 Even though Sri Lanka has adopted Euro 4 emission standards and is continuing with the vehicle emissions testing programme, a large number of inefficient vehicles remain on the road.

1.5°C compatible pathways show a rapid decline in direct CO₂ emissions from the transport sector, dropping to 5-8 MtCO₂/yr by 2030, and 0-4 MtCO₂/yr by 2050 from the 2019 level of 10 MtCO₂/yr. Such emissions reductions could be achieved through electrification, the share of which would increase to 3-7% by 2030 and 20-22% by 2050.
The updated NDC is expected to revitalise public transportation, as well as improve intermodal connectivity between rail, road and water-based transportation. According to the Sri Lankan government, implementation of the NDC is expected to reduce emissions by 4% compared to a business-as-usual (BAU) scenario for the sector.

Direct CO₂ emissions only are considered (see power sector for electricity related emissions, hydrogen and heat emissions are not considered here).

All values are rounded. Only direct CO₂ emissions are considered (electricity, hydrogen and heat emissions are not considered here; see power sector for emissions from electricity generation). Year of full decarbonisation is based on carbon intenstiy threshold of 5gCO₂/MJ.
