GHG Inventory

One of the strategies to address climate change is to reduce the amount of greenhouse gas emissions in the atmosphere. The international community recognized its importance when over 192 countries adopted the United Nations Framework Convention on Climate Change, whose ultimate objective is to stabilize greenhouse gas concentrations in the a level that would prevent dangerous anthropogenic interference with the climate system which should be achieved within the time frame sufficient to allow ecosystems to adopt naturally to climate change, to ensure that food production is not threatened and to enable economic development to proceed in a sustainable manner.

In the preparation of both the Initial National Communication (INC) and the Second National Communication (SNC), the Philippine government procured the services of consultants to conduct the national inventory and to write the inventory report. The Government saw the need to institutionalize the GHG inventory reporting process in relevant government agencies due to the sensitivity of data and information in these activities as well as meet the requirements, as Country Party to the UNFCCC, for a more comprehensive mitigation analysis for climate-responsive planning and regular submission of reports. Thus in 2011, the Climate Change Commission (CCC) spearheaded the institutionalization of the PGHGIMRS.

The Philippine Government has crafted the 2010 National Greenhouse Gas Inventory through hardwork and dedication of the PGHGIMRS and was completed last 2019. The 2010 Inventory was used in the projection of Business-As-Usual emissions scenario used for the Philippine’s First Nationally Determined Contributions.

After the institutionalization of the PGHGIMRS in November 2014, the lead sectoral agencies convened to agree on the details of the forthcoming inventory. Training workshops on the National GHG Inventory for each sector using the 2006 IPCC Worksheets and Software were conducted in the succeeding months to capacitate the agencies in doing the national inventory. 

In May 2019, the PGHGIMRS with the assistance from the UNFCCC Secretariat conducted a QA/QC Capacity-building workshop on the 2010 GHGI. The workshop yielded a number of findings, which were prioritized based on: (a) the importance to the overall inventory; and (b) level of capacity and resources available for implementation. Three (3) follow-up meetings were done in July 2019 to incorporate the improvements and address concerns on methodological issues arising from the QA/QC workshop and finalize the 2010 GHGI. Once finalized, the 2010 GHG inventory Report will be transmitted as part of the 3rd National Communication. 

Results of the 2010 GHGI were used as basis for the projection of business-as-usual emission scenario in the 1st Philippine Nationally Determined Contribution (NDC) and also used as basis in the formulation of the NDC policies and measures.
