Abstract: Under the “dual-carbon goals” (carbon peaking and carbon neutrality), the accelerated global transition toward green and low-carbon development has become an irreversible trend. As a key carbon-emitting sector in China, the transportation industry accounts for approximately 10% of the nation’s total carbon emissions. Transportation decarbonization is therefore critical not only for addressing global climate change challenges and fulfilling international emission reduction commitments but also for driving the industry’s green transformation, optimizing energy structures, enhancing public livelihood and ecological environment quality, and, ultimately, achieving sustainable development. Taking Chengdu as a case study, systematically, this paper (1) objectively summarizes the current status and achievements of green development in Chengdu’s transportation sector; (2) identifies bottlenecks hindering its green transition; (3) calculates carbon emissions across various transport modes in recent years using the GHG Protocol framework to identify key influencing factors; and (4) proposes targeted strategies to establish Chengdu as a national pioneer in developing innovative “dual-carbon” pathways for transportation. The findings are intended to provide decision-making support for building a low-carbon transportation system that aligns with Chengdu’s megacity development goals.
