Website and Mailing List

In order to share and archive the information, GIO developed a website which is updated by workshops. PDF files of presentations given at the workshop and proceedings of WGIA can be downloaded for each year. These documents contain valuable and unique information and are thus downloaded all over the world, especially the information on least-developed countries. Documents for downloading can be found at the link below:


A mailing list of persons related to GHG inventory in Asian countries is prepared and managed by GIO. This mailing list is used to announce COP events and other international meetings. If participants wish to distribute information, such as conferences and events in COP, this can be done so via WGIA-Mailing List. Information exchanged through WGIA-Mailing List may be posted on the WGIA website for public access if so requested or considered useful. Also, the WGIA network platform can be used in parallel with other existing network platforms to complement them and should not be regarded as a replacement or competitor. Brief Background Information on WGIA-Mailing List

The Greenhouse Gas Inventory Office of Japan (GIO) at the National Institute for Environmental Studies (NIES) developed the WGIA-Mailing List to serve as a primary support channel and to provide an opportunity for the WGIA community to share experience, knowledge and resources, voice concerns, seek advice and discuss topics of interest related to greenhouse gas inventories.

This is an initiative established for the WGIA community as an online regional network platform that all may take full advantage of through participation, according to the conclusions reached at Session III “Networking Experts in Region” at WGIA5. Currently, all participants in each WGIA subscribe to this mailing list.

WGIA-EFDB (Emission Factors Database)

In WGIA, participants share their experience with a focus on the estimation methods used in the GHG inventories, key category analysis and ways to address the problems faced in GHG inventory preparation and development to date.

In WGIA5, 2007, participants noted the utility of continuous and improved networking with stakeholders. Malaysia, Cambodia and Indonesia stated that a continuous database of emission factors for GHG inventory was needed. At that time no system for collecting GHG inventory data, such as activity data and emission factors, existed in developing countries. In Asia, some countries used emission factors of neighbouring countries with similar climate conditions, but there was no system or means by which to share such information. There was, therefore, a broad-based opinion concerning the need to develop a database for emission factors in order to share country-specific emission factors developed by WGIA participants.

Since WGIA7, GIO has collected a number of papers presenting country-specific emission factors developed for the various sectors. These values should be integrated in the Emission Factors Database (EFDB) being developed for the region.

One of the activities for the sectoral working group workshop during WGIA6 was to analyse data entered into the EFDB by closely scrutinising what environmental conditions, management practices or specific circumstances were developed for the EF. This meant that experts could discuss if an EF developed for another country may be “applicable” or “appropriate” for use in their own inventory. In this regard, experts could include, via adding remarks at the time of data entry in the EFDB, details as to what countries are “appropriate” for use of the EF factors, which would help other GHG inventory staff in the various countries in the region.
