To clarify the shared responsibility of carbon reduction related to EVs in the countries, it is necessary to assess the material flows of steel associated to the industry chain. This study constructed a multi-layer trade network model of “steel-electric vehicle” industry chain and identified key trade carbon transfer paths. The results firstly show the worldwide trade volume and the number of involved countries increased enormously from 2017 to 2021. Secondly, the non-renewable energies (coal) were diverted more from upstream countries. Finally, the trade patterns mostly flow from upstream (Brazil, Australia) to midstream steel producers (China, Germany), and then to downstream EVs manufacturers (USA), from which trade flows go back to middle and upstream countries. Instead, trade embodied carbon flows mainly into downstream developed countries. It reflects the huge imbalance among production process of different stages, energy consumed structure and trade carbon emissions in the worldwide “steel-electric vehicle” industry chain. Based on the results, this study proposes policy implications for promoting regional industrial ecological sustainability from the perspectives of industry chain, trading partners and countries.</div></div>","PeriodicalId":51021,"journal":{"name":"Ecological Economics","volume":null,"pages":null},"PeriodicalIF":6.6,"publicationDate":"2024-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142312251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The WE experience is interpreted in light of an earlier debate in the international development community over the mainstreaming of radical concepts that were purged of transformative meanings – becoming buzzwords that did not fundamentally alter existing practices. Wellbeing and the WE similarly risk becoming buzzwords: feel-good ideas that are hard to oppose, but which users can fill with their own meanings and political agendas. The WE's post-growth roots are contrasted with the pro-growth meanings given to it by organizations including the OECD and WEGo nations. The WE has nevertheless shown some promise in enabling <em>limited</em> steps in a post-growth direction in WEGo nations (within a broader context of continued pursuit of growth).

Despite the potentially positive symbolic effect in mobilizing a global agenda for combating deforestation, the EUDR faces several drawbacks and risks associated with three of its constitutive features: To be demand-oriented, having the value chain as the unit of intervention and holding a high degree of unilateralism.

Using the Tanzanian National Panel Survey, we then examine whether past experiences of shocks affect the adoption of crop diversification differently between poor and non-poor farmers. We rely on a threshold model to estimate heterogeneous impacts between poor and non-poor farmers. We find that poor farmers adopt crop diversification for robust food securities in response to drought/flood and large increases in food prices for purchase.
