Pathways to deep decarbonization of the passenger transport sector in Japan

The passenger transport sector accounted for 12% of Japan’s CO2 emissions in 2010. Two Deep Decarbonization Pathways are structured to investigate the way in which different technical and social transformations can reduce the transport-related energy use and GHG emissions. An advanced technological (AdvancedTech) scenario focuses mainly on the technological innovations and transformations in the transport and energy sector, but does not give consideration to social and behavioural factors. On the other hand, the balanced scenario is structured with the objective of developing a long-term strategy to achieve a drastic GHG emission reduction in transport sector by means of a balanced behavioural and technological changes.

Pathways to deep decarbonization of the passenger transport sector in the United Kingdom

A key challenge for transport policy in the UK is the Government’s own domestic climate legislation, which mandates “at least” an 80% reduction in greenhouse gas (GHG) emissions relative to 1990 levels by 2050. Past analysis reveals that achieving this target translates into a requirement for the carbon intensity of transport to decline by around 70% on average by 2050. We describe two new scenarios that provide distinctive visions of how passenger transport could evolve in the future, driven by rapid technological progress, changes to societal mobility trends, and the requirement to transition towards low or net-zero energy systems. Both of the scenarios presented achieve similar levels of decarbonisation by 2050, but take very different pathways towards that destination.

Pathways to deep decarbonization of the passenger transport sector in France

The transport sector is the main emitting sector and represented about 26% of total French GHG emissions in 2010. The French DDP team chose to develop two scenarios for the passenger transport sector consistent with the 2°C target and the SNBC objectives, reaching both a reduction of about 78% of CO2 emissions compared to 1990, down to about 20 MtCO2 in 2050. These two deep decarbonization pathways embody contrasting futures of the mobility demand, as well as the supply-side solutions that will be necessary.

Pathways to deep decarbonization of the passenger transport sector in Mexico

Current and historical patterns of uncontrolled urbanization and poor public transportation strongly encourage the use of private vehicles with an ever-lower occupancy rate in increasingly congested roads. The increasing surface of cities effectively expands the distances commuters need to travel everyday. The resulting rise in gasoline consumption has exceeded domestic refining capacity and imports account for half of total supply. The transport sector is the single largest source of GHG emissions in Mexico with a fourth of the total. Two scenarios are presented, both leading to a 50% reduction in annual CO2 emissions of the passenger transport sector by 2050 (50 MtCO2) compared to the level in 2010.
