The System of Environmental-Economic Accounting—Ecosystem Accounting (SEEA EA) was recently adopted by the united Nations Statistical Commission at its 52nd session in March 2021.
Following this significant milestone, a key dimension to increasing the uptake of the accounts is mainstreaming their application into policymaking. In response to this need, a technical report, Policy Scenario Analysis Using SEEA Ecosystem Accounting, has been developed. The report is an output of the Natural Capital Accounting and Valuation of Ecosystem Services (NCAVES) project, funded by the European Union.
The objective of the report is to improve the effectiveness of decisions for sustainable development by highlighting how use of the SEEA EA accounts in scenario analysis models can provide policymakers with a better understanding of the interconnections between society, economy and the environment, and hence lead to better decisions. The report provides an overview of how to link the ‘data push’ from the development of accounts with the ‘policy pull’ demand for information by policymakers. This report shows that policy scenario analysis can be informed or improved by applying ecosystem accounts in different types of models and modelling approaches. The report includes: an overview of core concepts and dimensions in scenario design; a technical review of state-of-the-art methods and simulation models for scenario analysis; and policy-relevant content to create an explicit link between the use of models and policymaking, based on successful country examples. Country examples are drawn from existing literature and studies undertaken as part of the NCAVES project in China and South Africa.
The report was prepared by Dr. Andrea Bassi under the guidance of UNEP and UNSD and was peer reviewed by experts on the SEEA EA and its policy applications.
A preliminary version of the report was presented to the African NCA Community of Practice; a recording of this webinar is available here.
The final report was launched during the Fifth Policy Forum on Natural Capital Accounting for Better Decsion Making.
Supplementing the technical report, the following case studies enable policy-makers to evidence the use of ecosystem accounts (and associated data) in environmental policy formation and evaluation, through deployment of the SEEA Ecosystem Accounting statistical framework and different types of modelling approaches.

The Economics of Ecosystems and Biodiversity (TEEB)
A TEEB Country Study (TCS) the ecosystem services that are vital to meeting the country’s policy priorities and makes recommendations on how these services can be integrated into policies. These recommendations depending on the country context can include policies for poverty alleviation, subsidy reform, land use management, protected area management, securing livelihoods, investment in natural infrastructure restoration and national accounting to include natural capital. Examples for Bhutan, Ecuador, Philippines, Liberia and Tanzania and other TEEB-inspired studies are available on the TEEB website: http://teebweb.org/where-we-work/.
The TEEB for Agriculture and Food project applies scenario analysis to policy decisions in the food and agriculture sector: http://teebweb.org/our-work/agrifood/
