Transport Greenhouse Gas Emissions Analyses and Reports

The Transport Greenhouse Gas (GHG) Emissions Database Projects supports the development of an ongoing series of comprehensive reports and concise analyses on transport GHG emissions. 

Two main reports will be developed in preparation of COP21, which will provide a comprehensive picture of the emissions trends and mitigation potential of the transport sector in various countries for the pre- and post-2020 periods.

The first report will highlight pre-2020 transport emission projections and mitigation options:

Report on Pre-2020 Transport Emissions Projections and Potential  

The pre-2020 report currently provides an overview of the emissions projections and mitigation potentials of the transport sector of up to 60 countries. The report is expected to scale up the summary to include data from 100+ countries (without mitigation data) using projection methodologies. 

The second report will provide transport projections and mitigation options till 2030.

Report on Post-2020 Transport Emissions Ambition in INDCs 

The report on Post-2020 Transport Emissions Ambition in INDCs is currently being developed with projections (for both BAU and low carbon scenarios) for remaining countries and summary analysis of post-2020 data being carried out in September (pending submission of 2030 targets for 50+ countries during this timeframe). The final report (including both pre- and post-2020 analyses) is targeted for publication and release by mid-November 2015.

Further to these, we present:

SLoCaT Analysis of INDCs from a Transport Perspective

The SLoCaT Partnership has conducted an analysis of INDCs in the transport sector, which is intended to guide the new climate change agreement to be reached at COP21 in December 2015. Among 133 INDCs submitted as of November 12, 2015, more than three quarters explicitly identify the transport sector as a mitigation source, and more than 60% of INDCs propose transport sector mitigation measures.

Among the 200+ transport measures proposed in the INDCs there is a strong bias passenger transport, which is included in 89% of INDCs identifying specific transport modes. Among these, urban transport measures are mentioned in 86% of INDCs, while strategies such as high-speed rail (2%), and walking and cycling (12%) have received relatively less attention.

A detailed outline and objectives of the existing and forthcoming knowledge products are presented in the GHG methodological note.

To guide the SLoCaT Partnership in its ongoing work on transport sector GHG analysis, it is intended to establish a review panel of external experts. The review panel can also play a role in recommending research directions after COP21.
