Experiences shared on coastal wetlands in GHG Inventories

See also new publication: Wetlands exchange – lessons learned

A lack of data for coastal wetlands and the potential for improving mangrove coverage were among the challenges and opportunities identified at a recent technical exchange ‘Incorporating Coastal Wetlands into Inventories’. The Partnership, with hosts the University of Queensland, held the event on 12-13 July 2018.

Government representatives from Australia, Cambodia, Fiji, Malaysia, Mexico, Papua New Guinea, Thailand, United Arab Emirates and the United States joined scientists, non-government organisations to share their experiences and recent science at the event.


A key component of the workshop was the presentation and discussion of case studies by Australia, Indonesia, the United States and the UAE.

Australia, the US and UAE have all used recent guidance from the IPCC, the Wetlands Supplement, to report on the ecosystems. Indonesia holds large areas of coastal ecosystems and currently reports on mangroves as part of their forest sector. Indonesia has also begun considering using the Wetlands Supplement.

This workshop aimed to 1) discover impediments to adopting the new guidance within the Wetlands Supplement; 2) document the process of including coastal wetlands within national greenhouse gas reporting in those countries which have made progress to adopting the Wetlands Supplement in order to better understand how the Wetlands Supplement can be used, and 3) develop solutions and share knowledge to facilitate enhanced adoption of the Wetlands Supplement.

Delegates left the exchange with an increased understanding of the guidance and confidence to explore next steps for including blue carbon in their inventories.

The Partnership has published lessons learned from the workshop in a short report. These lessons will also be discussed at the Partnership’s upcoming meeting on 19-21 September in Suva, Fiji.
