UN Climate Change 2 years ago

Happy birthday COP! 🎂 It has been 30 years since the opening of COP1 in Berlin. These United Nations Climate Conferences – or COPs  - convening nearly all countries of the world have achieved a huge amount since then. Milestone agreements such as the Kyoto Protocol at COP3 in 1997 and the Paris Agreement at COP21 in 2015 as well as other historic decisions at COPs over the years have strengthened the world’s commitment to confront the global climate crisis, and protect people everywhere. Just think – without these agreements, we would be headed for up to 5° Celsius of global heating, which most of humanity could not survive. We're now headed for around 3°C, which is still disastrous, and climate impacts hit countries, economies and people harder every year. So we need much more progress still. 2025 is a critical year for climate action: Under the Paris Agreement, all countries need to submit new, more ambitious national climate plans this year, showing how they will cut emissions more strongly and protect people, infrastructure, businesses and communities. As André Aranha Corrêa do Lago, President-Designate for #COP30 this November in Brazil, urged the world earlier this month: We need a global mutirão—a collective effort—against climate change and leave our differences behind. Every minute counts on the road to COP30.  Solidarity is the only way.

Sustainable construction is moving from exemplar projects to market-wide system design, with clean steel emerging as a critical test for whole life carbon policy. A new study suggests the global shift to low-carbon steel could be achieved without raising consumer costs through a revenue-neutral policy model, strengthening the case for low embodied carbon materials in mainstream procurement.

For contractors, developers and public clients, the issue is no longer whether green building materials can perform, but how governments can de-risk low carbon construction materials, reduce the carbon footprint of construction and support net zero whole life carbon targets without shielding high-emission incumbents.

The UK retrofit agenda is becoming central to environmental sustainability in construction. The National Retrofit Hub’s call for a stronger framework comes as electricity and gas prices begin to decouple, improving the life cycle cost case for heat pumps, energy-efficient buildings and electrified homes.

Retrofit policy now needs consistent standards, skilled delivery capacity and consumer protection, backed by whole life carbon assessment, lifecycle assessment and better evidence on building lifecycle performance. Public support for requiring data centres to share waste heat with nearby homes signals a shift in sustainable urban development, treating rejected heat as green infrastructure rather than waste.

Climate adaptation is also reshaping sustainable building practices. GRAHAM’s appointment to deliver the Oxford Flood Alleviation Scheme highlights rising investment in resilience, while reports of roads melting in eastern England expose the environmental impact of construction decisions based on historic weather assumptions.

The built environment is being asked to cut embodied carbon in materials while improving durability against heat, flooding and infrastructure stress. The strongest response will combine sustainable building design, low carbon design, circular economy in construction, sustainable material specification, environmental product declarations (EPDs) and end-of-life reuse in construction. BREEAM, BREEAM v7 and other performance frameworks are likely to play a growing role as clients demand net zero carbon buildings, resource efficiency in construction and credible carbon footprint reduction across the full asset lifecycle.
