NDCs cooling guide: Guidance for integrating the cooling sector into NDCs

United Nations 9 months ago

Cooling is one of the biggest untapped opportunities to deliver climate, health, and development gains together. While the sector already contributes seven per cent of global greenhouse gas emissions, and could double that share by 2050, over one billion people still lack access to life-saving cooling for health, food security, and medicine. This guide supports governments in confronting this challenge by integrating sustainable cooling into their Nationally Determined Contributions (NDCs). The NDC Cooling Guidelines offer a six-stage, step-by-step framework, supported by country case studies, to help policymakers assess hydrofluorocarbon and energy-related emissions, set sector-specific targets, and develop fully costed National Cooling Action Plans (NCAPs). The Guidelines emphasize Minimum Energy Performance Standards (MEPS), Kigali-compliant refrigerant phase-down, passive and nature-based solutions, as well as climate-responsive urban planning. These actions are underpinned by cross-ministerial coordination, a robust Measurement, Reporting, and Verification (MRV) system to track progress, and a strong focus on expanding equitable access. Together, they enable countries to integrate cooling measures into both adaptation and mitigation pathways. The NDC Cooling Guidelines were developed collaboratively by the UNEP Cool Coalition NDC Working Group, with contributions from the American University in Cairo; Climate and Clean Air Coalition (CCAC); Clean Cooling Collaborative (CCC); Collaborative Labeling and Appliance Standards Program (CLASP); Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) Proklima; the Ozone Secretariat; Sustainable Energy for All (SEforALL); United Nations Development Programme (UNDP); UNEP Copenhagen Climate Centre (UNEP-CCC); and UNEP United for Efficiency (U4E).

Westminster’s commitment to implement the Fingleton Review by 2027 has set a new direction for sustainable construction in the UK. The government’s plan to accelerate clean energy development and reduce dependence on fossil fuels promises a stronger pipeline for energy‑efficient buildings, green infrastructure and net zero carbon buildings. A dedicated infrastructure unit to fast‑track housing and major projects could stimulate private investment and support Whole Life Carbon Assessment at scale, improving building lifecycle performance and enabling more consistent delivery of low carbon design.

The policy shift signals that project speed will take precedence while environmental sustainability in construction must be safeguarded through credible environmental risk management. Developers implementing sustainable building design will need to integrate lifecycle assessment, life cycle cost analysis and sustainable material specification to meet both regulatory expectations and investor demands for accountability. The renewed focus on resource efficiency in construction aligns with circular construction strategies and end‑of‑life reuse in construction, reinforcing the circular economy in construction supply chains.

Geopolitical tension and record oil supply disruption underscore the urgency to decarbonise the built environment. The volatility of petrochemical‑based materials highlights the value of low embodied carbon materials, renewable building materials and eco‑design for buildings that reduce the carbon footprint of construction. Transitioning to carbon neutral construction supported by rigorous whole life carbon management can enhance resilience against energy price fluctuations and strengthen the competitiveness of green construction initiatives.

As the UK construction sector seeks to translate policy intent into delivery, success will hinge on embedding sustainable building practices and defensible whole life carbon strategies into every stage of design and procurement. Achieving environmental performance in line with BREEAM and the forthcoming BREEAM v7 framework will be critical for delivering truly net zero whole life carbon outcomes. Sustainable urban development and low‑impact construction can only be realised through transparent environmental product declarations (EPDs), robust life cycle thinking in construction and consistent carbon footprint reduction across all project phases.
