The transport sector, particularly in developing countries, plays a critical role in global energy consumption and greenhouse gas emissions reduction strategies – not only because transport sector emissions comprise nearly a quarter of global emissions today, but also because without pre-emptive action in developing countries, transport sector emissions may increase particularly rapidly, and the costs of future retroactive mitigation activities may be prohibitive. In this paper, the authors review existing methodologies for estimating transport sector GHG emissions and introduce a new methodology that solves the challenge of attributing emissions from large-scale transport sector interventions using a low-cost and scalable methodology. The authors’ methodology relies on emergent sources of big data — GPS data generated by multi-national transportation networked companies (TNCs), such as Uber and Grab, and high-resolution satellite imagery — to efficiently and effectively generate comparable traffic-induced GHG emissions estimates across multiple cities and countries.
