Knowledge Gaps and Policy Needs to Tackle Loss and Damage - Science for Adaptation Policy Brief #8

United Nations 1 year ago

The World Adaptation Science Programme Science-for-Adaptation Policy Brief on Knowledge Gaps and Policy Needs to Tackle Loss and Damage is the eighth issue in the series published by eight international agencies that form the World Adaptation Science Programme (WASP): UN Environment Programme (UNEP), the World Meteorological Organization (WMO), United Nations Framework Convention on Climate Change (UNFCCC), Intergovernmental Panel on Climate Change (IPCC), Global Environment Facility (GEF), Green Climate Fund (GCF), the United Nations University (UNU) and the United Nations Educational, Scientific and Cultural Organization (UNESCO). The Secretariat of the WASP is hosted at UNEP, Nairobi, Kenya. Loss and damage are increasingly mentioned in National Adaptation Plans and National Determined Contributions, but these documents say little about options to address loss and damage and largely miss non-economic loss and damage. How to avert, minimize and address loss and damage is still in question. This issue of the WASP policy brief discusses the foundation on multiple dimensions of the loss and damage, which is induced by inadequate action on climate change. It seeks to answer the following questions: What is the current state of knowledge and recognition of loss and damage in national policy? What are the key science gaps obstructing the effective implementation climate related loss and damage measures? What are the policy gaps and possible mechanisms to better address observed and projected loss and damage?

Digital regulation is reshaping sustainable construction through the UK’s new Digital Waste Tracking legislation, creating real-time accountability across the lifecycle of materials. This shift from rhetoric on the circular economy to verifiable operational systems reinforces circular economy in construction strategies and reduces the embodied carbon in materials that define much of the sector’s hidden footprint. By embedding data transparency into waste management, the policy aligns with life cycle thinking in construction and delivers measurable progress towards whole life carbon reduction. It transforms environmental sustainability in construction from principle to practice and prompts developers to rethink sustainable building practices around resource efficiency in construction and end-of-life reuse in construction.

Climate finance is emerging as the foundation for decarbonising the built environment. The £15 billion British International Investment strategy, including a £1.1 billion fund for coal transition, demonstrates a financial pivot toward net zero whole life carbon outcomes. Such investment supports the transition to carbon neutral construction and enables low carbon building programmes that combine life cycle cost control with sustainability performance. The move signals that public finance is prepared to underwrite industrial change, connecting sustainable building design with long-term value creation across the building lifecycle performance.

On a practical level, renewable energy infrastructure is now defining the power landscape for construction projects. Enviromena’s £825 million initiative to deliver a gigawatt of solar capacity highlights the integration of renewable building materials and low carbon construction materials into project planning. Decarbonised grids are lowering the carbon footprint of construction, enhancing the energy efficiency of both off-site operations and net zero carbon buildings. This reinforces eco-design for buildings based on lifecycle assessment and life cycle cost evaluation, strengthening sustainable material specification and encouraging green building products throughout the supply chain.

Europe’s Low Carbon Building Initiative is extending certification to renovation projects, turning sustainable design principles toward existing assets. The framework complements BREEAM and BREEAM V7 standards by prioritising embodied carbon assessment within refurbishment strategies and encouraging eco-friendly construction practices. Such mechanisms ensure that lifecycle assessment and whole life carbon assessment underpin decision-making even for retrofits, maximising returns through green infrastructure and low-impact construction. Reuse and adaptation of existing structures reduce the environmental impact of construction while promoting sustainable architecture consistent with net zero carbon commitments.

The sector is entering a stage of disciplined investment, data-driven oversight, and intolerance for wasted resources. Cleaner data streams, improved circular economy performance, and integration of low embodied carbon materials mark a decisive step toward sustainability in the built environment. Whole life carbon evaluation and sustainable construction frameworks are no longer optional aspirations but measurable realities guiding the future of the industry.
