Towards Decarbonising Transport 2023

A Stocktake on Sectoral Ambition in the G20

This publication analyses the current state of decarbonisation and climate ambition in the transport sectors of G20 countries. G20 countries are responsible for the lion’s share of global transport emissions. At the same time, they are also in the best position to encourage change, given their political and economic influence.

In light of India’s G20 presidency in 2023, and with emerging economies at the helm of the intergovernmental forum in 2022 (Indonesia), 2024 (Brazil), and 2025 (South Africa), this report seeks to support global discussions surrounding sustainable transport and the effort to achieve the goals stipulated in international climate accords, especially the Paris Agreement and the Glasgow Declaration. The report was first presented at a G20 working meeting in Panaji, the capital of the Indian state of Goa, on 19 July 2023, together with the public policy think tank of the Government of India NITI Aayog.

The document is an update of the report “Towards Decarbonising Transport 2018. A Stocktake on Sectoral Ambition in the G20”, published by Agora Verkehrswende, GIZ, and REN21. A consortium of seven leading research and international cooperation institutes, under the umbrella of the NDC Transport Initiative Asia, has contributed to the new edition of the report. Agora Verkehrswende completed the work with the support of the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), SLOCAT, WRI, ICCT, ITF, and REN21. The project was supported by the International Climate Initiative (IKI) of the German Federal Ministry for Economic Affairs and Climate Action.
