This Databases contains an overview of National Communications (NCs) and Biennial Update Reports (BURs) from a wide range of Annex I and non-Annex I countries (including historic and projected transport emissions as a share of economy-wide emissions). Information is collected directly from NCs and BURs, and includes transport emissions baselines, historic and projected growth disaggregated by passenger and freight activity, noting any economy-wide or transport-specific emissions targets and any transport sector related mitigation policies identified within NCs.
