Capacity Development on GHG Inventories in Asia

WGIA Workshop on Greenhouse Gas Inventory in Asia

Hiroshi Ito

Abstract The Greenhouse Gas Inventory Office (GIO) of Japan has organised the “Workshop on Greenhouse Gas Inventories in Asia (WGIA)” since 2003. The workshop is tasked to improve GHG inventory dataset credibility in Asia and help bind countries within the Asian region. Participating countries are Cambodia, China, India, Indonesia, Japan, the Republic of Korea, Lao PDR, Malaysia, Mongolia, Myanmar, the Philippines, Singapore, Thailand and Vietnam (14 countries). Since the 6th WGIA (WGIA6) in 2008, WGIA has been convened as part of the “Kobe Initiative” of the G8 Environment Ministers' Meeting. WGIA participants are government officials, inventory compilers, researchers and staff in international organisations. The workshops have been held in other Asian countries to help attract more attendees. Participants from many countries can conduct face-to-face discussions at WGIA. Many achievements were realised through the workshops, in particular:

• Establishment of the WGIA network platform to exchange information on climate change and mitigation of GHG emissions as well as GHG inventory

• Sharing of information and experiences that can be beneficial for other countries

• Identifying common problems and possible solutions

• Updating of the status of national inventory development

This collaborative approach may be applicable for other regions.

Keywords WGIA • GHG inventory • Biennial update reports • Nationally appropriate mitigation actions • MRV • GIO of Japan • Capacity development • Mutual learning

Key Message to Policymakers

• GIO has conducted a Workshop on Greenhouse Gas Inventories in Asia (WGIA) annually for 12 years.

• Workshop continuity helps develop networks.

• WGIA operates to exchange information among inventory experts.

• Face-to-face workshops are necessary for developing relationships of mutual trust.

Introduction to WGIA

GHG Inventory in International Negotiations

The 5th Assessment Report published by the Intergovernmental Panel on Climate Change (IPCC) in 2013 stated that “the atmospheric concentrations of the greenhouse gases carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) have all increased since 1750 due to human activity”.

In accordance with Articles 4 and 12 of the United Nations Framework Convention on Climate Change (UNFCCC), all Parties to the Convention are required to submit greenhouse gas inventories to the Conference of the Parties (COP) under the convention as part of their national communications (NCs) at a frequency determined by the COP.

GHG inventories are important for ensuring the transparency and accuracy of each country's mitigation actions by quantifying anthropogenic GHG emissions. In this respect, national GHG inventories, which provide information on the GHG emissions and their trends over time, play a critical role as a basis for decisionmakers to design and implement strategies for mitigation actions and GHG emission reductions within their country.

Inventories form the basis of national policy development because they can be used to:

– Identify the major sectors where abatement will have a real impact.

– Predict and compare impacts of mitigation measures.

– Choose cost-effective options.

Inventories are essential to monitoring of impacts of mitigation policies and measures because:

– Policymakers need to know if policies are working.

– They need to reflect impacts of mitigation actions and thus require careful choice as regards method.
