Strong sustainability in the SEEA and the wider indicator landscape

Abstract

The System of Environmental-Economic Accounting (SEEA) remains neutral when it comes to the weak and strong sustainability worldviews. However, although its manuals do not contain any references to these concepts, it can support both through physical and monetary accounting. Given that strong sustainability is better suited to monitor environmental sustainability, we provide insights into how SEEA can contribute to promote the use of strong sustainability indicators.

From a strong sustainability perspective, environmental sustainability requires identifying elements of natural capital to be preserved (critical natural capital) and at the level at which they should be preserved (reference values). SEEA and its manuals do not explicitly define the first element, but the concept of 'reference values' is implicitly embedded with the 'ecosystem condition accounts' introduced in the Ecosystem Accounting (EA) manual. As such, EA is the most relevant element of the SEEA in terms of advancing strong sustainability accounting. Given that ecosystem condition accounting is still in its early stages and that ecosystem condition is currently challenging to determine, three actions are proposed to better integrate strong sustainability in SEEA. First, the next revision of the SEEA Central Framework should be more explicit in how SEEA supports weak and strong sustainability. It should also consider how SEEA is linked to the wider indicator landscape (including the Sustainable Development Goals and the Global Biodiversity Framework). Second, ecosystem condition accounting needs to be further developed, as the more abundant extent accounts cannot capture the quality of ecosystems. Third, ecosystem condition accounting could build on other strong sustainability indicator initiatives such as Planetary Boundaries or the Environmental Sustainability Gap framework that have consistently integrated reference values in the accounting practices. These actions would provide additional means to interpret environmental sustainability beyond the direction of progress as is often the case.
