Transport Toolkit

Developing strategies for clean, efficient transport

The Low Emission Transport Toolkit supports development planners, technical experts, and decision-makers at national and local levels to plan and implement low emission transport systems that support economic growth. This toolkit helps users navigate a variety of resources to identify the most effective tools to build and implement low emission development strategies (LEDS) for the transport sector.


Globally, the transport sector is responsible today for approximately 23% of total energy-related carbon dioxide emissions, and its emissions are increasing at a rate faster than that of any other sector. With countries and cities facing a rising need for transport services over the coming decades, governments have a unique opportunity to meet this demand and enable economic growth while minimizing greenhouse gas emissions through the implementation of comprehensive policies, behavioral change, and adoption of energy efficient technologies for the transport sector.

Learn about the six key actions necessary to successfully implement a low emission development strategy for the transportation sector
image/svg+xml Evaluate system Implement & monitor Prioritize & plan Develop alternatives Assess opportunities Create baseline Key actions

Assess opportunities

Utilize the Avoid, Shift, Improve framework, to meet growing transport demand with less environmental impact. This approach widens the focus of transport development beyond conventional technologies to include solutions that consider the policies and behaviors driving the demand for transport.

View related tools Next action

Evaluate system

Assess the current transport situation in your country or region by researching and evaluating existing plans, policies, practices, strategies and programs related to transport and land use.

View related tools Next action

Create baseline

Track emissions and development improvements by establishing baselines that measure current and projected transport demand, supply, greenhouse gas emissions, and land use, assuming no low-emission actions are taken.

View related tools Next action

Develop alternatives

Establish development objectives and policy measures, then integrate potential transport development opportunities into various alternative scenarios that would achieve those objectives. The alternative scenarios should be compared with the business as usual scenario in order to determine potential impact.

View related tools Next action

Prioritize & plan

Prioritize alternative scenarios based on factors such as economic, environmental, and social benefits & costs, technical & institutional capacity & barriers, and greenhouse gas emission impacts. Once a particular pathway is prioritized, a specific transportation development plan can be adopted, consisting of implementable policies and systems that would result in optimal impacts such as increased employment, enhanced mobility, improved health/safety, expanded market access, reduced congestion, and avoided emissions.

View related tools Next action

Implement & monitor

The action plan should define a timetable, roles and responsibilities, financial sources, performance metrics, outreach and partnership activities, and a plan for continuous monitoring and refinement. Proper MRV (monitor/measure, reporting, and verification) mechanisms should be established to ensure desired impact and continued improvement.

Planning instruments aim to reduce the need for trips with personal vehicles. These instruments focus on promoting cities that are compact, connected and coordinated; a shift to public transport and non-motorized transport options:
  • Land use planning
  • Public transport and infrastructure
  • Non-motorized transport
  • Multimodal integration.

Regulatory instruments are actions that aim to reduce or restrict use of personal vehicles and influence the type of vehicles that should be used:
  • Traffic management
  • Fuels and vehicle efficiency

Economic instruments have two definitions in this toolkit. They can be methods to discourage use of certain forms of transport by putting a price on use (e.g. low emission zones). They can also be traditional and/or innovative financing opportunities to fund transport projects:
  • Financing

Information instruments are ‘soft’ measures that provide knowledge to decision-makers, technical experts and the general public. The objective is inform stakeholders about the impacts of transport options:
  • Governance and public awareness
  • Air quality and greenhouse gas emissions
  • Impact assessment
  • Fleet management.

Technology instruments aim to improve the effectiveness and energy efficiency of transport modes:
  • Shared mobility
