The devolved administration inventories are consistent with the UK inventories submitted to the United Nations Economic Commission for Europe (UNECE).
What is included?
The Devolved Administrations (DA) AP inventory presents emissions on a by source (emissions are allocated to the source sector in which they occur) basis, and figures and percentages within the reports refer to these datasets, unless otherwise stated.
In addition, the report presents estimates of DA emissions from international aviation and shipping (which are excluded from national inventory data, in accordance with UNECE reporting protocols).
What isn’t included?
The DA AQ Inventory is reported using a UK territorial coverage, and thus excludes the Crown Dependencies and Overseas Territories. Emissions from offshore oil and gas exploration and production sources are not allocated to any country, and are reported separately within an "Unallocated" inventory category.
