Greenhouse Gas (GHG) Inventory Waste Sector

The GHG inventory preparation is coordinated by the Climate Change Division under the Ministry of Environment and Water (KASA). Five (5) working groups (WG) have been setup for this purpose, which comprises of the Energy Sector, Industrial Processes and Product Use (IPPU) Sector, Agriculture Sector, Land Use, Land Use Change and Forestry (LULUCF) Sector and Waste Sector. KASA has designated DOE as the Implementing Agency in charge of developing a greenhouse gas inventory for the waste sector.

The DOE served as the primary agency in the preparation of the report on GHG emissions from the waste sector. As a result, DOE established the Committee on Working Group on Waste Sector, which is responsible for collecting and analysing data on GHG emissions. The committee members appointed include government and government-related agencies such as the Ministry of Housing and Local Government, National Solid Waste Management Department, Indah Water Consortium (IWK), National Water Services Commission (SPAN), Sewerage Services Department (JPP), The Malaysian Palm Oil Board (MPOB), Malaysian Rubber Board (LGM), and Sarawak Natural Resources and Environment Board.

The GHG inventory for the waste sector consists of the inventory of GHG emissions from various sources such as solid waste, scheduled wastes, domestic wastewater, industrial wastewater, and other industrial wastes such as from palm oil industries, natural rubber industries, pulp and paper industries, and poultry industries.

The main GHG emitted from the waste sector is methane gas (CH4). Methane is emitted mainly during the anaerobic decomposition of organic waste disposed at solid waste disposal sites and during the handling of domestic and industrial waste under anaerobic conditions.

By developing an inventory for the waste sector, the country can assess and evaluate the emissions sources and trends and forecast and analyse future emissions. This would be an essential tool in identifying cost-effective emission reduction potential and developing climate policies in Malaysia. The GHG inventory could also be used to measure the benefits of emissions-reduction actions and to define goals or targets for future GHG reduction.
