Transport Task Group
The Transport Task Group (TTG) was established in 2014 to serve as a voluntary platform for G20 countries to share experience and work together to improve the energy and environmental performance of motor vehicles, especially heavy-duty vehicles (HDVs).
The transport sector accounts for ¼ of global CO2 emissions from fuel combustion. Road transport accounts for ¾ of transport CO2 emissions. HDVs account for <5% of the global on-road vehicle fleet but ~40% of its energy consumption.
TTG supports G20 economies in achieving air quality and public health objectives. Transport tailpipe emissions linked to 385 (274–493) thousand premature deaths from ambient PM2.5and ozone in 2015. Global transport health impacts increased 6.6% from 2010-2015. An estimated 84% of premature deaths and nearly $1 trillion in health damages were in G20 economies.
Build domestic support and enhance capability for action to reduce the energy and environmental impacts of transportation.
Identify and exchange
Identify and exchange best practices among G20 economies on the implementation of cost‑effective energy efficiency and emission control measures in the sector.
Analyze and reach out
Assess the opportunities, barriers, and costs, and benefits of policy options, and recommend a course of action for participating G20 countries.
Engage in a strategic discussion of the group’s activities and future vision with TTG’s 15 participating economies: Argentina, Australia, Brazil, Canada, China, the EU (co-lead), Germany, India, Indonesia, Italy, Japan, Mexico, Saudi Arabia, the United Kingdom, and the United States (co-lead).
The value of internal cooperation
- Rapid growth and complexity of the transport sector poses a challenge to policymakers
- Policy options span regulatory, fiscal, and voluntary measures, often involving multiple ministries
- Technical issues span efficiency and emissions measurement, vehicle technology, electric vehicles, compliance programs, regulatory impact assessment
- TTG participants have noted the challenge and opportunity to think bigger and the value of a collaborative forum to facilitate the exchange of ideas quickly and readily
Five principles for reducing air pollution from transportation
1) Establish a legal framework for reducing emissions
- Air quality standards
- Transboundary agreements
- National emissions ceilings
- Nationally Determined Contributions
- Emissions inventory
- Vehicle emissions measurement
- Air quality monitoring
- Cost-benefit analysis
- Air quality action plans
3) Ensure vehicles entering the fleet are as clean as possible
- Standards for new vehicles/engines and fuels
- Compliance and enforcement
- Zero-emission vehicle policies
- Feebates and other fiscal incentives
- Identify and eliminate high-emitting vehicles
- Fleet transition through procurement and accelerated turnover
- Introduce low/zero-emission zones in highly-impacted areas
- Fiscal incentives
- Public transport improvements
- Pedestrian areas
- Walking and bicycling networks
- Planning more livable cities

The group is co-led by the United States Environmental Protection Agency (US EPA) and the European Union’s Directorate-General for Climate Action (DG-CLIMA). It is supported by two implementing organizations: the International Council on Clean Transportation (ICCT) and the Global Fuel Economy Initiative (GFEI). Participation in the TTG is voluntary and open to all G20 economies and their neighbors.
