Organisational structure The Transport Decarbonisation Alliance (TDA) is managed by a Steering Committee where Countries, Cities and Companies are equally represented and they oversee the alliance direction and guidelines for action as agreed in the TDA Annual meeting. The Steering Committee is composed by three members of each one of the constituencies (3 Cs) together with 2 representatives of the Paris Process on Mobility and Climate that has consistently been instrumental from the very outset of the TDA.

Description The TDA accelerates the worldwide transformation of the transport sector towards a net-zero emission mobility system. The Transport Decarbonisation Alliance – a “coalition of the willing” to decarbonise transport.

The Transport Decarbonisation Alliance (TDA) was launched in 2018 to bring together countries, cities/regions and companies, the “3 Cs”, as the major drivers in sustainable, low carbon mobility: 1. Substantiate scaled-up ambition for the transport sector 2. Design common pathways and strategies 3. Set up “3 Cs Communities of Interest” 4. Set the scene for more ambition and action in policy framework on climate change and sustainable development.

The TDA ambition is to become the most visible and influential forum for public and private cooperation and to be the game changer that will ensure all the transport sub-sectors contribute to the Paris Agreement’s objectives.

Objectives A unique collaboration to accelerate the worldwide transformation of the transport

sector towards a net-zero emissions mobility system before 2050.

TDA is part of the 12 climate commitments made at the One Planet Summit in September 2017.

Activities TDA 3 Cs members sign the TDA charter and

commit to: 1. Make a public commitment to accelerate action to decarbonise transport to meet a “net-zero emissions” sector as soon as possible; 2. Share regular up-to-date information about their objectives, actions, progress and experiences in decarbonising transport; 3. Promote strategic direction, action guidelines and tools provided by the TDA ecosystem; 4. Contribute actively to the promotion of the TDA objectives (as TDA Ambassadors);

A total of 70 organisations have currently signed the call for Zero Emission Freight Vehicles.

Goals The Transport Decarbonisation Alliance (TDA) brings together countries, cities/regions and companies, the “3 Cs”, as the major drivers in sustainable, low carbon mobility. The TDA has the following goal that they will aim to achieve in a collective effort:

1. Substantiated scaled-up ambition for the transport sector: designing a common vision for “front-runners” 2. Tangible action: setting up “3 Cs Communities of Interest” 3. Effective advocacy: influencing political decision-makers in key international fora on climate change (e.g. UNFCCC), sustainable development (e.g. UN High Level Political Forum – SDGs); international political processes (e.g. EU, G7, G20, B20) and through bilateral dialogues.

Comments on indicators and goals
How will goals be achieved 1/ Accelerates and scales up ambition for the transport sector by outlining a shared vision for front-runners in transport decarbonisation.

2/ Enables action through joint ‘Communities of Interest’ (working groups) that tackle critical drivers and disruptors to low carbon mobility from the perspective of the 3Cs. At the moment three main groups on Active Mobility, Urban Freight Zero Emissions and Hydrogen. 3/ Provides an advocacy platform to influence political decision-making in international fora on climate change and sustainable development, as well as in other key multilateral processes, bilateral dialogues and gatherings of the private sector and local and regional governments.

Have you changed or strenghtened your goals
Progress towards the goals Via this call to action TDA wants to communicate the substantial demand for zero emission freight vehicles to suppliers. Together we can accelerate the transition towards zero emission logistics. Already 81 organisations have signed the call,covering 263,687 zero emission freight vehicles.
