On Youth Day at #COP31, UN Climate Change Executive Secretary Simon Stiell receives the 2026 Global Youth Statement. Shaped through local, national and regional youth conferences around the world and led by YOUNGO, the official children and youth constituency, it brings the priorities of young people together in a single policy document. It’s a powerful reminder that the generation who will live longest with these decisions must have a real say in shaping them.

Throughout Youth Day at #COP31, young people take part in a range of activities, including the Youth Negotiator Lab. There, they workshop ideas on the climate issues that matter most to them and step into the shoes of negotiators to see how consensus is built, gaining the skills to shape the process from the inside.

Delegates take part in the 6th interagency meeting with partners supporting NDC implementation at #COP31. Nationally determined contributions (NDCs), are each country’s climate plan under the Paris Agreement, setting out how it will cut emissions and adapt to climate impacts. Turning them into action, and strengthening them, is essential. Meetings like this bring partners together to help countries do exactly that.

As #COP31 reaches its midway point, UN Climate Change Executive Secretary Simon Stiell holds a press conference on the state of the negotiations ahead of the Subsidiary Bodies’ closing plenaries. With the first week’s technical work drawing to a close and key issues still on the table, his message was clear: there can be “no collective success without compromise from every Party.”

Throughout #COP31, press conferences give journalists and delegates a window into what’s happening inside the negotiations. They keep the world informed and give people the chance to ask questions directly, holding the process to account and helping make it more transparent and accessible to all.

As the first week of negotiations at #COP31 draws to a close, delegates huddle in contact groups to make as much progress as they can on a range of issues. These smaller groups are where much of the detailed work happens, as
The latest climate-policy signals carry clear implications for sustainable construction, despite limited direct evidence of major new low carbon building projects, breakthrough low carbon construction materials or regulatory changes. COP31 debates on the timing of IPCC science, rising concern over El Niño-related costs and renewed forest-finance commitments point to growing pressure on the built environment to prove environmental sustainability in construction through stronger climate resilience, whole life carbon assessment and credible embodied carbon reporting.
If climate-risk evidence informs the 2028 global stocktake, regulators, lenders and investors are likely to demand more robust sustainable building design, flood resilience, heat adaptation and lifecycle assessment across major assets. This would strengthen the business case for net zero carbon buildings, low carbon design and net zero whole life carbon strategies, while exposing weak claims around green construction, eco-friendly construction and carbon neutral construction.
Canada’s support for tropical forest protection also reinforces scrutiny of timber and renewable building materials. Nature-based carbon policy may increase demand for responsibly sourced green building materials and low embodied carbon materials, while raising expectations for sustainable material specification, environmental product declarations (EPDs) and clearer evidence on embodied carbon in materials. The direction of travel favours life cycle thinking in construction, circular economy principles and circular construction strategies, including resource efficiency in construction and end-of-life reuse in construction.
Reports of weaker Australian construction and commercial-property sentiment are economically relevant but do not amount to sustainable construction news on their own. They do suggest a tougher financing environment for developers seeking to fund energy-efficient buildings, green infrastructure and higher standards such as BREEAM and BREEAM v7. The core challenge remains unchanged: decarbonising the built environment is becoming unavoidable, yet whole life carbon, life cycle cost and building lifecycle performance are still too often treated as optional when credit conditions tighten.
