The topic comprises two key areas:

• the reduction of GHG emissions needed to meet climate change targets for the transport sector targets
• state of the art in measuring vehicle and infrastructure GHG emissions (direct and indirect measurement), and individual emissions (tools for influencing user choices and behaviour).

Elements include calculation and allocation of emission reduction targets, international harmonisation (projects, cooperation activities), impact assessment methods and tools (studies, reports, cost-benefit analyses, technical feasibility, environmental impact, user behaviour, user acceptance), data and methods for communicating evaluation results.

The topic will survey carbon-saving vehicle and generic technologies, and evidence of their impact on emissions. Elements include electro-mobility (vehicles and infrastructure); eco-driving support; connected, cooperative and automated vehicles; alternative energy fuels; IoT; AI etc. The objective is to identify relevant low-carbon technologies and tools, and assess how far they can reduce transport emissions and which emerging technologies may pay off in the future.

Focusing on infrastructure, the topic explores how solutions for smoother traffic flow, better vehicle-infrastructure cooperation, and multi-modality can contribute to reduce GHG emissions. Elements include best practice for adaptive traffic management and control, demand management, inter-modal optimisation, management of incidents, parking and public transport fleets etc. The potential impact of C-ITS (Cooperative ITS), intelligent parking, contactless payment and ticketing, and big data analysis will also be explored from emission-saving perspective.

The topic will survey existing solutions to reduce goods transport GHG emissions, e.g. to shorten supply chains and optimise urban freight deliveries. The objective is to identify solutions with evidence of GHG emissions saving. Solutions ready for deployment will be highlighted (truck parking information and reservation, signal priority, truck-sharing, e-vans etc.), together with promising innovations (truck platooning, autonomous vehicles for people and goods, e-trucks).

Gathering an inventory of existing schemes, e.g. MaaS, car-sharing, bike-sharing, ride-hailing, on-demand transport, and incentives for modal shift, the topic will also review studies of MaaS impact on GHG emissions and energy use. Elements include the climate impact of measures to improve accessibility or substitute for travel, of solutions integrating multimodal mobility services, and of the potential of next-generation shared and automated mobility services for on-demand and first-last mile travel.

The topic will survey relevant regulation and legislation, governance (roles and responsibilities of public actors), business models, policy measures and their effectiveness, funding sources and financial tools (current opportunities, future needs), and standardisation. Elements will include system and service roadmaps, deployment scenarios and associated impacts, and will propose tools to enhance international cooperation, improve public awareness, and improve coordination and cooperation with other EU and global initiatives.
