TRANSPORT

Transport emissions account for a quarter of global CO₂ emissions. We're developing guidance for companies in this sector to set science-based targets. See our updated policy regarding Automakers (OEMs).

Guidance for the transport sector

Why take action?

As the fastest-growing source of emissions worldwide, it is critical for the transport sector to become more sustainable and help keep global temperature rise well-below 2ºC / 1.5ºC.

Passenger, freight and OEM

Transport companies can set targets using the Science Based Targets initiative (SBTi)’s Sectoral Decarbonization Approach (SDA) Transport tool: a technical resource to model science-based targets for direct and indirect transport emissions. The tool is focused on the passenger and freight land transportation and Original Equipment Manufacturers (OEMs) sectors and provides greenhouse gas emissions accounting guidance and best practices for science-based target setting.

Shipping

The SBTi has developed the developed the Science Based Target Setting Guidance and Tool for the Maritime Transport Sector, to enable companies within this sector to set emission reduction targets in line with 1.5°C. This was developed with the support of WWF, University Maritime Advisory Services (UMAS) and the Smart Freight Centre (SFC).

A month-long public consultation was held from March 2021 to April 2021. Expert in the maritime sector provided feedback on the draft guidance and target-setting tool to help ensure the criteria and guidance are robust, clear, and practical.

The SBTi Maritime Guidance is now available. Download the Target Setting Tool and view the Frequently Asked Questions.

Our updated OEMS policy

The SBTi has paused automaker target validations and target updates

The SBTi is temporarily pausing near- and long-term target validations and target updates for automakers until 1.5°C scope 3 targets for use-phase emissions from new road vehicles are developed and approved. This decision is effective immediately. Companies with existing commitments will be granted extensions if affected by this policy.

Addressing specific emission categories directly related to a company’s main activity has significant potential to improve the credibility and consistency of decarbonization claims for both near- and long-term targets. As the vast majority of automakers’ overall emissions originate from end-users driving the vehicles, company-wide decarbonization claims aligned with 1.5°C should accordingly be consistent across vehicle use-phase emissions, accounted for under scope 3 category 11 ‘use of sold products’.

There is currently no sectoral decarbonization approach (SDA) for transport that allows companies to align their use-phase emissions targets of new road vehicles with 1.5°C pathways. To ensure automakers can align the majority of emissions with a 1.5°C trajectory, this temporary pause has been put in place until the SBTi is able to update the SDA Transport tool pathways and make these respective changes to the SBTi Criteria.

This policy applies to the following:

Automakers: These companies cannot submit scope 3 category 11 targets until 1.5°C-aligned pathways for new road vehicles are released. This applies to all newly manufactured road vehicles classified as: new light duty passenger vehicles, new light commercial vehicles, new medium freight trucks and new heavy freight trucks.

This policy does not apply to the following:

Autopart manufacturers: Such companies with direct use of sold product emissions may continue to use the well-below-2°C aligned pathways for new road vehicles available in the SDA Transport Tool for setting targets. Alternatively, autopart manufacturers with direct use of sold products can apply other valid scope 3 target setting methods for informing target ambition for their category 11 emissions.

Our aim continues to be to develop robust methodologies that will support decarbonization at the pace and scale required by science. The SBTi is prioritizing the development of 1.5°C-aligned pathways for automakers. In the meantime, for any questions view our FAQs or contact transport@sciencebasedtargets.org

Sectoral Decarbonization Approach (SDA) Transport tool

Our Sectoral Decarbonization Approach (SDA) Transport tool can be used to model science-based targets for direct and indirect transport emissions. Key features include:

Addition of new transport modes, with 15 transport sub-sectors now included;
Development of a new approach for original equipment manufacturers (for scope 3, use phase science-based target-setting); and
Inclusion of the International Energy Agency Beyond 2°C scenario (B2DS).

The sectors available in the tool include:

Passenger: 2-3 wheelers, light-duty vehicles, buses, mini-buses, urban rail, non-urban rail
Freight: 2-3 wheelers, light commercial vehicles, medium freight trucks, heavy freight trucks, rail
OEMs: New light duty vehicles, new commercial vehicles, new medium freight trucks, new heavy freight trucks

Transport mode definitions can be found in the guidance document, along with a step-by-step description on how to use the tool, GHG accounting guidance, best practices for target-setting and more information on the science-based target approaches used in the tool.

The tool can be used by passenger transport companies, logistics service providers, shippers, carriers, postal companies, road vehicle manufacturers, auto part manufacturers, and generally companies with large transport emissions in their value chain.

To complement these target-setting resources, a tool is now available for manufacturers of passenger light-duty (PLDV) vehicles to model science-based GHG reduction targets for their scope 1&2 emissions. This tool applies the Sectoral Decarbonization Approach method and uses data from the International Energy Agency 2017 Energy Technology Perspectives report and 2017 Mobility Model data.

Take a look at this visualization for more information on indexed projections and trajectories embedded in the tool and derived from the Mobility Model of the International Energy Agency.
