Global Share of CO2 Emissions from Domestic Aviation in Total CO2 Emissions from Transport by Country

The global share of CO2 emissions from domestic aviation relative to total transport emissions varies significantly by country. In 2023, Azerbaijan stands notably high at 12.65%, followed by the United States at 10.23% and China at 9.32%. European countries like France, Sweden, Italy, and the UK exhibit lower percentages, indicating different transport and aviation dynamics.

In analyzing past trends, Azerbaijan, the United States, and China have shown notable stability in these metrics, reflecting consistent, though varied, domestic aviation impacts on broader transport emissions. High values in Azerbaijan suggest a larger reliance on domestic flights within the transport sector, contrasting with European counterparts who may favor rail or road transport for domestic travel needs.

Future trends to watch continue to involve shifts in technological advancements and policy changes aimed at reducing aviation's carbon footprint. Alternative fuels and improved efficiencies could alter these trends, especially if international agreements push for sustainable aviation practices. Variations in domestic travel demand, especially post-pandemic, could further fluctuate these figures, with green technologies potentially reshaping long-term trajectories.
