13 to 16 February 2023 | Open meeting


With an aim to limit global warming well below 2°C and within 1.5°C under the Paris Agreement, countries all agreed to report the current status of Greenhouse Gas (GHG) emissions and regularly update the mitigation plans in Nationally Determined Contributions (NDCs) with more ambitious commitments for greenhouse gas emission reductions. A reliable emissions inventory system would support those national and global GHG reduction commitments.

The GHG inventory system plays a major role for countries to measure the current emission levels, make projections for future scenarios, and report the achievement of their national commitments. It also provides a better understanding of current climate actions and policies, as well as the level of improvement needed to reach carbon neutrality. National greenhouse gas inventory is the basis for the development of the Enhanced Transparency Framework (ETF) established under the Paris Agreement and is essential for the fulfillment of reporting obligations of the Agreement.

While Asia-Pacific region contributes to over 55 per cent of the global GHG emissions,  the national teams are still having difficulties managing and collecting the GHG-related data.  In this context, this year’s workshop is designed to provide an in-person training course including lectures and exercises on GHG Inventory System for government officials and experts from Asia, including national statistics offices (NSOs).

Objectives and Expected Outcomes

The 5th Greenhouse Gas Inventory System Training Workshop aims to provide an opportunity for developing countries from Asia to build capacity and engage in policy dialogue on utilizing national GHG inventories for the design and implementation of NDCs under the Paris Agreement. The workshop is expected to have the following outcomes:

  • Enhance capacity of government officials and experts on enhancing GHG inventory system by experiencing hands-on actual GHG estimation practice based on 2006 IPCC guideline
  • Exchange of advanced knowledge and experiences of national governments in the Asia region on developing GHG inventory systems
  • Advancing networks among participating organizations, countries, and regions to promote the implementation of the Paris Agreement

Target Audience

This workshop aims to engage up to 50 government officials and representatives, national research institutions, and academia particularly from Asian countries, concerned directly with the development and management of national GHG inventory systems. Priorities for participation will be given to the attendees who joined the online workshops held in 2021 and 2022 at least once.

Schedule and Format

The workshop will be held in a hybrid format from 13 to 16 February 2023 in Bangkok, Thailand as some of the speakers will be participating in the workshop online. The entire workshop will be conducted in English.


This workshop will be organized by the United Nations Office for Sustainable Development (UNOSD), United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP), and Thailand Greenhouse Gas Management Organization (TGO).
