The transport sector in Thailand made up 29% of the country’s total direct CO₂ emissions and had the second highest share in primary energy demand of 36%.20 Energy consumption of this sector has increased steadily since 1990, growing by around 40% between 2010–2019.
Thailand’s transport sector is dominated by fossil fuels (92% in 2019), mainly oil (86%).20 In all our analysed scenarios, fossil energy demand from the transport sector peaks by 2019 and declines thereafter. A Paris Agreement compatible pathway requires a rapid electrification of the transport sector, reaching a 13–43% share of the sector’s final energy demand by 2050.
Thailand has adopted several policies in the transport sector to reduce emissions, including an electric vehicle roadmap and a goal for 100% of new vehicle sales to be EVs by 2035.37 In 2021, Thailand’s National Electric Vehicle Policy Committee announced that 30% of vehicles produced in Thailand will be zero-emission by 2030.38 In addition, Thailand provides tax benefits for battery manufacturing and supplies. Earlier Thailand had a biofuel blending mandate of 10% which has now been lowered to 7%.39 To enhance mass transit systems, the government is adopting policies with integrated development plan for rail, public transport and water transport.36

38 While global cost-effective pathways assessed by the IPCC Special Report 1.5°C provide useful guidance for an upper-limit of emissions trajectories for developed countries, they underestimate the feasible space for such countries to reach net zero earlier. The current generation of models tend to depend strongly on land-use sinks outside of currently developed countries and include fossil fuel use well beyond the time at which these could be phased out, compared to what is understood from bottom-up approaches. The scientific teams which provide these global pathways constantly improve the technologies represented in their models – and novel CDR technologies are now being included in new studies focused on deep mitigation scenarios meeting the Paris Agreement. A wide assessment database of these new scenarios is not yet available; thus, we rely on available scenarios which focus particularly on BECCS as a net-negative emission technology. Accordingly, we do not yet consider land-sector emissions (LULUCF) and other CDR approaches.
