Abstract Information :

The UK GHG Inventory is widely regarded as world-leading; it receives favourable feedback via UNFCCC experts within global capacity building projects to showcase the UK inventory data and methods. The inventory is developed and maintained to adhere to the IPCC quality objectives of: 1) completeness (i.e. no gaps – all anthropogenic GHG emissions by sources – fugitives included – removals by sinks); 2) accuracy (i.e. using best available UK data and evidence; applying models that accurately represent UK circumstances); 3) transparency (annual report that sets out results, data inputs, assumptions, and methods for every emission source and sink); 4) comparability (applying methods that enables comparability of the UK GHG inventory against those provide by other reporting parties to the UNFCCC); 5) consistency (applying methods and data that generate as accurate a trend across the time series as practicable). UK inventory experts have played a leading role in the development of the global GHG data reporting and QA systems, via IPCC method guideline development (many UK experts from across academia and industry have been invited to work on IPCC products as Lead Authors or Review Editors) and UNFCCC transparency and reporting processes (e.g. expert reviews of country submissions, development of Paris Agreement reporting systems). UK experts have a long track record of providing support to many countries to enhance their GHG evidence base and reporting. The UK is one of only three countries globally that conducts ‘top-down’ verification of its inventory; the InTEM verification work is world-leading and the results are reported transparently annually.
