The Federal Statistical Office of Germany held the 28th Meeting of the London Group on Environmental Accounting from September 26–29, 2022, in Siegburg, Germany. There were more than 50 attendees from different countries, amongst whom were MAIA’s partners from the World Conservation Monitoring Centre (WCMC). While the bulk of attendees joined in person, several attendees joined online due to travel restrictions to discuss and present their research papers.

The symposium was divided into seven sessions, all of which dealt with various aspects of environmental accounting:

• Ecosystem services in biophysical terms

• Monetary valuation of ecosystem services

• Alignment between the SEEA Central Framework (CF)/Ecosystem Accounting (EA) and the System of National Accounts (SNA)

• Integrating environmental activity accounts and deriving indicators

• Ocean accounts

• SEEA physical flows and derived indicators

During the four days, more than 20 research papers and presentations were discussed, demonstrating the substantial advancement and work efforts linked to the application of SEEA. The UN Committee of Experts on Environmental-Economic Accounting (UNCEEA) and the Technical Committee on the SEEA EA provided updates at the beginning of the meeting. The focus of the first two days was mostly on ecological accounting.
