Linear vs. circular views of the human-nature relationship in the history of economic thought

The long-run history of environmental and natural resource economics is quite well known. To name just a few milestones, it usually includes the Physiocrats, Jevons’s coal question, Marshall’s and Pigou’s externalities, Hotelling’s 1931 model, Coase’s theorem, Hardin’s tragedy of the commons, up to Nordhaus’s DICE model. This history, in which resources are considered inputs and ecosystems sinks, offers a quite linear and dualistic view of the human- nature relationship. It is, however, not the only one to tell. Since the 18 th century at least, there has been another, less-known economic tradition opting for a more integrative, organicist, and circular view of the human-nature nexus, from Linnaeus’s economy of nature to American land economics and contemporary ecological economics. This presentation will quickly explore these two traditions and give more details on one example from the organicist, circular tradition: the combination of chemistry and economics in the mid-19 th century to design a circular agricultural scheme, as a lever for transforming the entire economic system.

Life Cycle and Systems Thinking Methods to Support Policy Design and Evaluation when Transitioning to a Decarbonised, Circular Economy

Transitioning to a decarbonised, circular economy is a complex task that requires a system thinking approach. Life cycle assessment (LCA) is a widely used method for evaluating the environmental impact of a product or process throughout its entire life cycle. This policy- oriented seminar argues that incorporating life cycle and systems thinking perspective into policy design and evaluation can support the ongoing transition to a decarbonised, circular economy.

European sustainability targets and policy assumptions in 2030 and beyond: a foresight assessment for circular economy. Case: Textile sector 

Transition to circular economy is an important aspect in European sustainability targets for 2030. This presentation focuses on the circular economy in the EU27, in particular with respect to recycling and re-use. The talk describes the EU-level policy context for objective development, the roadmap towards the objectives, and the assumptions that were considered to be essential in accomplishing the objectives for 2030. It further anticipates some risks involved, and wild cards to be considered towards 2050. A case study on the textile sector in Finland is used as an example: how can a sustainable textile system be created by 2030?
