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

CircEUlar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。CircEUlar将开发新的建模方法，从系统的角度分析循环性，考虑到：1)非物质化和向以服务为基础的经济转型，以限制材料库存的增长；2)通过维修、维护、再利用延长材料库存的寿命；3)废物处理和材料回收。CircEUlar的方法将是全面的，将整个经济范围的材料库存和流动、温室气体(GHG)排放和相互关联的行业的工业价值链的新数据和模型结合在一起，并深入分析流动性和建筑作为材料密集型需求部门。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。CircEUlar还将专注于数字化，将其作为非物质化和供应链循环的潜在推动者。欧盟委员会综合了多个领域的数据、知识和专门知识，其中包括：1)企业和消费者倾向于采用循环经济措施的实证分析；2)流程一级创新和循环经济商业模式的行业投入；3)全经济范围的材料库存和流动的模型分析，以及社会变革的政策杠杆。欧盟将把关于循环经济潜力和影响的新观点纳入欧盟和全球模拟框架，以：1)分析实现温室气体净零排放的替代途径；2)测试循环生产和消费的有效政策杠杆。3)评估气候、环境、经济和社会成果，与欧洲绿色协议目标保持一致。

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.
