UN Climate Change 3 years ago

Exactly 30 years ago today, the world’s first intergovernmental treaty to address climate change came into force. 🌍 The United Nations Framework Convention on Climate Change (UNFCCC) was a remarkable achievement for its time. Back in 1994, the science on climate change was far less certain than it is today. The UNFCCC lifted a line from one of the most successful multilateral environmental treaties in history (the Montreal Protocol, in 1987): it bound member states to act in the interests of human safety even in the face of scientific uncertainty. Today, we are better off because of it. Since entering into force on 21 March 1994, the UNFCCC has provided the basis for international climate negotiations, including agreements such as the Kyoto Protocol (1997) and the Paris Agreement (2015). It has: ✅ set standards and advanced action on reducing emissions ✅ accelerated the development and deployment of renewable energy technologies ✅ mobilized the private sector and individuals to take action ✅ increased the accountability of those taking #ClimateAction ✅ helped countries adapt to the effects of climate change And, perhaps most importantly, the UNFCCC has proven that we can only succeed by working together. #ClimateLingo

Sustainable construction is shifting from voluntary ambition to core risk management. The UN’s warning that current pledges still imply about 2.8°C of warming strengthens the case for sustainable building design, whole life carbon assessment and life cycle cost modelling at the earliest project stage.

Post-drought subsidence risks show why climate resilience must sit beside embodied carbon, whole life carbon and building lifecycle performance, particularly where rewetting can shrink, swell or destabilise soils beneath foundations.

The redesigned £249m Bridgwater Tidal Barrier underlines the same point: green infrastructure must withstand flood risk, inflation and long-term operational pressures.

Decarbonising the built environment is moving into construction plant and site logistics. The Lower Thames Crossing is becoming a major test for hydrogen-powered equipment, with JCB and Toyota pursuing combustion and fuel-cell routes to reduce diesel dependence. The sector’s priority is no longer abstract net zero carbon messaging, but practical carbon footprint reduction across machinery, fuel supply and delivery. Stronger lifecycle assessment, resource efficiency in construction and low carbon design will be needed to prove real gains in the carbon footprint of construction.

Low-carbon heat and materials are gaining commercial weight. The National Geothermal Centre says the UK could unlock 10GW of geothermal heat by 2050, supporting energy-efficient buildings, low carbon building schemes and net zero carbon buildings where grid capacity is constrained. Holcim’s renovated Zug headquarters points to circular economy in construction, low carbon construction materials and sustainable material specification as boardroom-level priorities.

Claims around green concrete and green building products need robust environmental product declarations (EPDs), scrutiny of embodied carbon in materials and credible routes to end-of-life reuse in construction. BREEAM, BREEAM v7 and net zero whole life carbon standards will increasingly shape eco-design for buildings, circular construction strategies and environmental sustainability in construction.
