| Abstract | This study quantified emission within the metropolitan city of Colombo (locally known as the Western province) for the base year 2016, using the Global Protocol for Community-Scale Greenhouse Gas Emission Inventories 2.0. The study used GPC 2.0 BASIC+ framework to deduce emissions based on scope and sector level segregation under the land boundary defined as the metropolitan City of Colombo which includes the Colombo, Gamapaha and Kaluthara Districts. Emission was formulated based on individual sectors and emission sources prior accumulating them into forming a well devised city specific inventory. The BASIC+ inventory level emission reporting for the base year 2016 generated 54% (9,954,229 tCO2e) emission from the transportation sector, 36% (6,644,013 tCO2e) emission from the stationary energy sector, 9% (1,610,884 tCO2e) emission from waste, 1% (212554 tCO2e) emissions from Agriculture and a 0.04% ((7,880 tCO2e) emission from Industry. Scope 2 and Scope 3 accounted for almost 42% of the total emissions, mainly due grid-based consumption and international transboundary aviation and waterborne navigation. A total emission of 18,429,560 tCO2e (18 Mn tCO2e) was emitted during the year 2016 with a 3.06 tCO2e per capita emission under BASIC+ and a per capita of 0.78 tCO2e under the BASIC inventory. An assessment of potential policy impacts on the key emitting sectors i.e. Stationary energy, Transport and waste was evaluated. Emission forecasting under the BAU scenario provides that without any mitigation implementations the total city emission will be 28,419,833 tCO2e by 2040. After the policies were implemented it was estimated that by 2040 there will be a 36.6% of emission reduction compared to BAU. |
