B. National Inventory Roadmap outlined a trajectory of -45% to -55 % GHG emissions reduction by 2030, -55% to - 65% by 2040 and -85 % to -90 % by 2050. The inventory that resulted from CORINAIR90 (CEC, 1992) and subsequent modifications from IPCC methodology still structures the present day methodology in what concerns activity data and methodology. Under the evaluation of the first communication the inventory was subject to a review made by an international team. All national communications up until the present day (last was the 7th National Communication, submitted in 2017) were also reviewed by international experts. These exercises had an important role in problem detection and contribute to overall improvement.
