United in Science 2024

United Nations 2 years ago

The science is clear – we are far off track from achieving global climate goals, threatening a sustainable future for all. The impacts of climate change and hazardous weather are reversing development gains and threatening the well-being of people and the planet, according to a new multi-agency report coordinated by the World Meteorological Organization (WMO).  Greenhouse gas concentrations are at record levels, fuelling temperature increase into the future.  The emissions gap between aspiration and reality remains high. Under current policies, there is a two thirds likelihood of global warming of up to 3 °C this century, says the United in Science report. Human-caused climate change has resulted in widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere. The year 2023 was the warmest on record by a large margin, with widespread extreme weather. This trend continued in the first half of 2024.  The United in Science offers much-needed grounds for hope. It explores how advances in natural and social sciences, new technologies and innovation enhance our understanding of the Earth system and could be game changers for climate change adaptation, disaster risk reduction and sustainable development.  International collaboration, comprehensive governance frameworks for integrated observing systems and innovative financing models are needed.

The latest developments in sustainable construction indicate that carbon management is becoming integral to building performance and supply chain resilience. The installation of Europe’s largest vanadium flow battery in East Sussex signals growing investment in grid‑scale energy storage systems designed to reduce the carbon footprint of construction and support energy‑efficient buildings. Integrating renewable building materials and low carbon construction materials with large‑scale energy storage reflects a clear shift toward whole life carbon assessment and lifecycle assessment approaches that underpin low carbon design and net zero carbon buildings. This alignment of technology and policy demonstrates environmental sustainability in construction moving beyond experimental stages into scalable models of eco‑friendly construction.

Essity’s £30 million recycled fibre facility in Northumberland highlights how circular economy initiatives are embedding life cycle thinking in construction. These circular construction strategies and resource efficiency in construction initiatives reinforce the circular economy in construction, promoting end‑of‑life reuse in construction and enabling sustainable material specification. By prioritising low embodied carbon materials and eco‑design for buildings, the sector is aligning with BREEAM and BREEAM v7 standards that measure whole life carbon performance and environmental impact of construction across the supply chain.

The industry now recognises that decarbonising the built environment depends on integrating energy systems, low carbon building materials, and data‑led whole life carbon methodologies. Reducing embodied carbon in materials and improving building lifecycle performance are transforming sustainable building design from policy aspiration into commercial practice. Green construction and sustainable building practices are becoming the foundation of sustainable urban development, where the net zero whole life carbon target defines both environmental sustainability and long‑term life cycle cost efficiency. Green building materials, green infrastructure and carbon neutral construction are driving this transition toward a credible, scalable model of sustainable design and carbon footprint reduction that aligns innovation with global sustainability goals.
