GRBP noted that the Inland Transport Committee (ITC), at its February 2023 session, had decided to develop a climate change mitigation strategy and requested its subsidiary bodies for inputs (GRPE-89-06).

In turn, GRPE had established a task force on the ITC climate change mitigation strategy (GRPE-89-39).
