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 and aviation
We are currently developing science-based target setting methods, tools and guidance for shipping and aviation companies. Contact the project leads for more information.
The SBTi transport sector development project is led by WWF.
Phase one of the project (2017-2018) resulted in a set of technical resources to support corporate science-based target setting for transport activities (covering land transportation for passenger and freight, and OEMs).
Phase two of the project will produce science-based target setting methods, tools and guidance for shipping and aviation companies.
Phase one was developed with the participation of a group of experts and project supporters (industry and non-industry representatives):
We counted on the support of three technical partners (global organizations working on sustainability and transport):
- Smart Freight Centre (SFC)
- Partnership on Sustainable, Low Carbon Transport (SLoCaT)
- International Council on Clean Transportation (ICCT)
We also had advice from the following technical experts:
- Ecofys, a Navigant Company
- International Energy Agency (IEA)
We also wish to thank the following companies for their financial contribution and/or technical input to this project:
BMW Group, Daimler AG, Deutsche Post DHL Group, General Motors Company, La Poste, Manufacture Française des Pneumatiques MICHELIN, Groupe Renault, SNCF, Volvo Group
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.
