Intergovernmental Panel on Climate Change (IPCC) – Call for Data

Working Group III of the IPCC is launching a call for quantitative data on climate footprints and cost for mitigation options within the transport sector. This call for data specifically focuses on results for land-based passenger and freight transport, as well as maritime transport, to be used for the Sixth Assessment Report (AR6).

The role of working group three of the IPCC is to assess and synthesize the literature on climate change mitigation. In doing this the IPCC collaborates with different branches of the scientific community on making the results of their research available in a structured and accessible form and trough this enabling transparent and rigorous assessments.  The IPCC WGIII is now for the first time launching an official call for data from the life cycle assessment and transport research communities to support the sixth assessment cycle.  The call provides a unique opportunity to contribute to a common data repository that will help inform the work of the IPCC WGIII.
