The International Transport Forum's (ITF) Decarbonising Transport initiative was officially launched in 2016 with the support of the Corporate Partnership Board (CPB), where CPB partners have committed to the core funding of the development of the project. Over the past two years, this core funding has enabled the framing, planning and execution of the project, as well as to allow the ITF to engage in fundraising opportunities, participate in outreach activities, invite more than 40 project partners (in addition to CPB partners) from multiple sectors, develop communication strategies, and to further expand the scope of the project. The Decarbonising Transport initiative offers decision makers tools for selecting CO2 reduction measures that work. It provides the best possible assessment of the impact of given decisions on CO2 emissions. It is non-prescriptive in that it does not advocate specific measures but assesses impacts. It is also inclusive in that it engages with stakeholders across multiple sectors, organising for instance workshops at the technical and political levels, as well as developing a global policy dialogue on transport and climate change with decision makers on options for action based on non-prescriptive findings will help develop packages of mitigation measures that are both effective and politically viable.
