This sector relates to the following sub-sectors: Air Transportation, Automobiles, Marine Transportation, Land Transportation.

Air Transportation

Each section below relates to the TPT Disclosure Framework principles of Action and Accountability. The below provides further guidance for sub-elements 4.1 and 4.2. The TPT welcomes comments on this guidance to ensure it is as useful as possible for preparers and users. The text is open for comment until Friday, 24 November.

This sub-sector includes air freight & logistics, and airlines industries. Air freight and logistics companies provide freight services and transportation logistics to both businesses and individuals. The airlines industry is comprised of companies that provide air transportation globally to passengers for both leisure and business purposes.

1. Drive long-term uptake of sustainable aviation fuels (SAFs), including interim focused actions3,5,7,10,13,14

  • procure and invest in bio-source SAFs, and emerging SAF technologies, including fuels derived from waste, biomass, agricultural residues, and power-to-liquids (PtL).
  • show a strong commitment to R&D to advance SAF technologies to reduce the green premium and improve carbon efficiency; and
  • engage with policy makers to advocate for supportive policies and incentives for SAF adoption.

2. Improve operational efficiency of fleet and ground operations1,4,10

  • replace older aircraft with newer, more fuel-efficient designs;
  • optimise interior designs for in-flight weight reductions (e.g., seats, equipment, galleys);
  • streamline operations to carry more payload per flight;
  • determine optimal flight paths, altitude accuracy, and landing configurations;
  • improve efficiencey of ground operations, including single engine taxiing and use of electric or hydrogen-powered ground vehicles.

3. Invest in infrastructure & technological advancements

  • contribute to and accelerate the development of hydrogen powered low-GHG emission aircrafts and associated infrastructurel; and 
  • improve the electrical grid at airports to support high-powered charging required for potential electric/hybrid aviation.

4. Manage demand for Aviation

  • demand management through pricing strategies; and
  • shift of short-haul flights to high-speed rail and behaviour changes.

  • total net SAF delivered by SAF type (mass);6
  • total blended SAF delivered by SAF type (mass);6
  • total electricity charged and used for aircraft propulsion (GWh).6
  • direct (Scope 1) emissions from, e.g. mainline aircraft and jet fuel, sustainable aviation fuel, mainline vehicles;2
  • indirect (Scope 3) emissions from e.g. mainline aircraft fuel production, venture investments;2
  • emissions intensity expressed as gCO2e per revenue tonne kilometre (gCO2e/RTK) or gCO2e per revenue passenger kilometre (gCO2e/RPK);4,12
  • target boundary: SBTi recommend targets should be set on a well-to-wake basis;11
  • account for and target non-CO2 induced effective radiative forcing effects;10,12,14
  • lifecycle emissions factor per SAF type (LSf);8
  • total CO2 emissions reductions from SAF(tCO2e);8
  • total emissions from the electricity charged and used for aircraft propulsion – CO(tCO2e).6
