Watch the Climate Metrics presentations discussing approaches to measuring and managing mitigation in the built environment. From the special issue launch event at the "Beyond 2020" conference.
Can appropriate carbon metrics in combination with carbon budgets be developed and used by built environment professionals, clients and civil society? Is it feasible to have a scalable approach? Can governments provide clear, useful targets to the products / construction / real estate industries? Based on research in a just published Buildings & Cities special issue on Carbon Metrics, new findings are presented. An overview introduces latest developments in global warming indicators and potential applications at building and city levels.
The credibility and use of carbon metrics depend on improved transparency, accuracy and data quality. Clear targets and benchmarks based on a scientific carbon budget can provide clarity to the many supply- and demand-side actors and can be used to establish requirements for individual projects as well as larger strategic plans . The creation and integration of target values for the built environment into decision making will need to involve a multi-scale and multi-actor approach.
Carbon metrics can help to create assessments and how carbon budgets can be used as a target value and/or assessment scale at building, city and building stock levels.

Two Key Messages for COP31
Space Heating & Cooling in NDCs 4.0: Nationally Determined Constributions (NDCs) are at the heart of the UNFCCC Paris Agreement. NDCs embody each country's efforts to reduce their emissions and adapt to the impacts of climate change. So it is essential to include the building stock (particularly space heating and cooling) in the next NDCs.
Realistic Retrofit: Residential buildings are major users of energy and emitters of CO2. What constitutes realistic retrofit? Affordable, practical low-carbon policies for homes are described for both the Global North and Global South.
Thomas Lützkendorf and Nick Eyre send their messages to COP31: prioritise the building stock in NDCs and implement policies for practical retrofit. Watch their videos - for links to the videos click on "More" below:
Practitioners’ Views of POE
Post-occupancy evaluation (POE) is widely valued but weakly embedded in practice. Ant Marsh, Kate van Someren, Lara Clarke and Tom Randall (Arup Building Performance and Commissioning Services) explain the findings from a survey and focus groups with UK construction industry practitioners. They identified fragmented responsibility, split commercial incentives and a persistent fear of “bad news”. Making POE routine requires a shift from producing reports to a focus on improving outcomes by owning and acting on learning.
