From Grey to Green: Better Data to Finance Nature in Cities - State of Finance for Nature in Cities 2024

United Nations 2 years ago

The State of Finance for Nature in Cities 2024 report: From Grey to Green: Better data to finance nature in cities, highlights the need for better data and tools to help cities integrate Nature based Solutions (NbS) into their financial and planning frameworks. The report showcases how investments in urban nature can support cities in addressing climate change, biodiversity loss, and land degradation, with global NbS financing needing to rise from USD 200 billion to USD 542 billion by 2030. Through case studies and an innovative Urban NbS Framework, this report guides cities on how to track, budget, and scale their investments in nature, offering a path toward greener, more resilient urban futures.

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.
