The Paris Agreement on climate change sets an overall long-term direction for climate change policy which should be in line with the ambitious target of limiting temperature increase (’well below 2°C’ above pre-industrial levels, and to aim for a temperature increase of not more than 1.5°C’). Therefore, each sector of human activity, including the Transport sector, must define its course of action whilst taking into account: a decarbonisation timeline of 2050-2060 for the most developed, and 2060-2080 for less developed economies.
For the Transport sector, the goal is to largely decarbonise and move from 7.7 Gt emissions/year down to 3 or 2 Gt by mid-century, while ensuring climate resilience of its infrastructures. Transport will be part of a “net-zero emission” economy, in which remaining emissions from specific sectors will need to be captured and sequestered or off-set through other means.
The Paris Process on Mobility and Climate (PPMC) proposes the development of a Global Macro-Roadmap through a phased action process, covering a 2020-2050+ timeline and thereby covering both short as well as mid- to long-term actions. This Roadmap aims to give a realistic (technically feasible) vision, with an operational focus for each segment of the Transport sector (people and freight; road, railway, aviation, waterborne; urban and rural). It is driven by new sustainable and inclusive growth opportunities called for by the SDGs.
The Roadmap focuses on identifying a balanced package of actions taking into account the main sustainable transport paradigm which combines Avoid (reduce unnecessary travel through e.g. land use planning or logistics redesign and halting counterproductive regulation that incentivizes travel by individual motorized vehicles), Shift (shift movement of goods and people to the most efficient modes, by scaling up good practices) and Improve (improve environmental performance of fuels and powertrains, intermodality and transport management).
