The Secretariat organized the first assessment of closed projects under the Special Programme in 2022. This assessment aimed to synthesize findings on management structures, coordination, communication and awareness-raising, project components, financing, and specific circumstances. In December 2024, the Special Programme Secretariat launched the second independent assessment. For more information, please download the complete report Independent Assessment of the Closed Projects under the Special Programme Report (December 2024). Each project factsheet "Independent Assessment of the Closed Projects under the Special Programme Report (December 2024)" will be available soon.
This news batch contains no substantive sustainable construction development: no major breakthrough in low carbon construction materials, no new whole life carbon assessment mandate, no building-code reform, no retrofit programme, no procurement shift, no BREEAM v7 update and no significant project case study advancing net zero carbon buildings.
The relevant signal is indirect but important. COP31 debate over the timing of the next IPCC reports could shape the 2028 global stocktake, influencing national policy on whole life carbon, embodied carbon, lifecycle assessment, retrofit finance, planning standards and the carbon footprint of construction. Warnings over El Niño costs and weakening natural carbon sinks strengthen the case for climate-resilient, energy-efficient buildings, low carbon design and faster cuts to operational emissions and embodied carbon in materials.
For the construction sector, the absence is commercially revealing. Environmental sustainability in construction remains too often downstream of climate diplomacy rather than central to it, despite the built environment’s major role in energy demand, resource use and emissions. Sustainable building design, eco-design for buildings, circular economy in construction, sustainable material specification and building lifecycle performance need clearer policy treatment if governments are serious about decarbonising the built environment.
The practical agenda remains unchanged: net zero whole life carbon, credible environmental product declarations (EPDs), low embodied carbon materials, life cycle cost analysis, end-of-life reuse in construction, resource efficiency in construction and circular construction strategies must move from specialist practice into mainstream procurement. Without that shift, green construction and eco-friendly construction risk remaining policy aspirations rather than measurable progress in sustainable building practices.
