CircEUlar (Developing circular pathways for a EU low-carbon transition)

循环项目旨在了解社会向净零排放循环经济转型的动力和杠杆。circular将开发新的建模方法，从系统角度分析循环：1)非物质化和向服务型经济的过渡，以限制材料库存增长；2)通过维修、维护、再利用延长物料库存的使用寿命；3)废物处理和材料回收。circular的方法将是全面的，将经济范围内的材料库存和流动、温室气体（GHG）排放和相互关联行业的工业价值链的新数据和模型相结合，并对交通和建筑作为材料密集型需求行业进行深入分析。这两个重点领域拥有大量的材料库存，循环转型的潜力，以及对循环消费和生产实践的强烈依赖。circle还将专注于数字化，作为去物质化和供应链循环的潜在推动者。circeular整合了多个领域的数据、知识和专业知识，包括：1)企业和消费者对循环经济措施倾向的实证分析；2)行业对流程级创新和循环经济商业模式的投入；3)对经济范围内的物质库存和流动以及社会转型的政策杠杆进行建模分析。circular将把关于循环经济潜力和影响的新见解纳入欧盟和全球建模框架，以便：1)分析实现温室气体净零排放的替代途径；2)检验循环生产和循环消费的有效政策杠杆。3)根据《欧洲绿色协议》的目标，评估气候、环境、经济和社会的成果。

The CircEUlar project aims to understand the dynamics and levers for societal transformation towards a net-zero emission circulareconomy. CircEUlar will develop new modelling approaches for analysing circularity from a systems perspective accounting for: 1)dematerialisation and the transition to a service-based economy to limit material stock growth; 2) lifetime extension of material stocksthrough repair, maintenance, reuse; 3) waste treatment and material recycling. CircEUlar’s approach will be comprehensive, combiningnew data and modelling of economy-wide material stocks and flows, greenhouse gas (GHG) emissions, and industrial value chainsacross interlinked sectors, with deep-dive analysis of mobility and buildings as material-intensive demand sectors. These two focus areashave large material stocks, potential for circular transformation, and strong dependence on both circular consumption and productionpractices. CircEUlar will also focus on digitalisation as a potential enabler of dematerialisation and supply chain circularity. CircEUlarintegrates multiple fields of data, knowledge and expertise including: 1) empirical analysis of firm and consumer propensities towardscircular economy measures; 2) industry input on process-level innovations and circular economy business models; 3) modelling analysisof economy-wide material stocks and flows, and policy levers of change towards societal transformation. CircEUlar will integrate newinsights on circular economy potentials and impacts into EU and global modelling frameworks for: 1) analysing alternative pathwaysto net-zero GHG emissions; 2) testing effective policy levers for both circular production and consumption. 3) assessing outcomes forclimate, environment, economy and society, in line with European Green Deal objectives.
