EPSRC : Charles Gillott : EP/R513313/1In an attempt to limit global temperature increase to 1.5 degrees C, the UK is committed to reducing greenhouse gas emissions to net-zero by 2050. The built environment is currently responsible for over 40% of the UK's greenhouse gas emissions, and is its largest contributor of waste. An increasing proportion of built emissions come from embodied carbon, referring to emissions from the extraction and manufacture of materials; construction, maintenance and demolition of buildings; and the processing and disposal of waste. A circular economy (CE) attempts to reduce resource consumption and waste generation - and thus embodied carbon - by retaining materials at their highest level of usefulness for as long as possible. Increasingly, policy promoting a CE is being seen across the globe, with strategies to achieving this including the retention of existing buildings, reuse of components, and recycling of materials.This project will identify policies that are promotive of CE in the Canadian and UK built environments, including those that apply at the national (e.g. building regulations in the UK and national construction codes in Canada) and sub-national level (e.g. local authority or provincial planning requirements). How policies promote different CE strategies will be assessed, allowing the homogeneity and characteristics of the policy landscape to be compared within and across the two countries. Building upon this, the success of different policy instruments in influencing construction practice will be considered. This will result in cross contextual learnings, and the formation of recommendations to increase adoption of a CE in the Canadian and UK built environments.

为了将全球气温上升限制在1.5摄氏度以内，英国承诺到2050年将温室气体排放量减少到净零。建筑环境目前占英国温室气体排放量的40%以上，是其最大的废物来源。建筑排放中隐含碳的比例越来越大，隐含碳指的是材料开采和制造过程中的排放；建筑物的建造、维修和拆除；以及废物的处理和处置。循环经济（CE）试图通过尽可能长时间地保持材料的最高可用性来减少资源消耗和废物产生，从而减少所含的碳。在全球范围内，越来越多地看到了促进节能减排的政策，实现这一目标的策略包括保留现有建筑、再利用组件和回收材料。该项目将确定在加拿大和英国的建筑环境中促进CE的政策，包括那些适用于国家（例如英国的建筑法规和加拿大的国家建筑规范）和次国家层面（例如地方当局或省级规划要求）的政策。将评估政策如何促进不同的环境行政战略，从而比较两国内部和两国之间政策格局的同质性和特征。在此基础上，将考虑不同政策工具在影响建筑实践方面的成功。这将导致跨上下文学习，并形成建议，以增加在加拿大和英国的建筑环境中采用CE。
