2023 Report to the Committee of Permanent Representatives on Private Sector Engagement Tackling the three planetary environmental crises requires a transformative shift in markets, sectors and systems. This means ambitious action from the private sector is critical, and that is why the United Nations Environment Programme (UNEP) is seeking to build wider and deeper collaborations that have impact with lasting solutions. UNEP would like to update the Committee of Permanent Representatives on its engagement with the private sector. This report sets out the evolving policy context that highlights the role of the private sector in addressing the three planetary environmental crises; the pressure on business to act; how UNEP has refined its approach to private sector engagement including the due diligence process; how we are strengthening collaborations with other United Nations (UN) agencies and others.
Construction’s shift to sustainability continues to draw attention as financing models increasingly support change across the supply chain. Lincoln CDM Services has adopted invoice finance to strengthen collaboration between contractors and suppliers, ensuring delivery of sustainable building practices. Stable funding is proving as critical as low carbon construction materials or energy-efficient buildings, safeguarding long-term adoption of sustainable building design.
Concerns over waste management are intensifying, with industry experts warning that construction and demolition waste could stall progress toward net zero Whole Life Carbon. The lack of clear policy and delayed investment is restricting recycling and reuse, undermining circular economy in construction efforts. Greater focus on end-of-life reuse in construction and resource efficiency in construction is now seen as essential to protect achievement of carbon footprint reduction goals.
Repurposing of outdated fossil fuel infrastructure in the US and Europe highlights potential pathways for the sector. Projects converting coal plants into data centre energy hubs illustrate how circular construction strategies can bring new value to redundant assets. This approach reduces embodied carbon in materials, cuts the carbon footprint of construction, and reinforces sustainable construction as a driver of wider decarbonising the built environment efforts.
Urban development continues to be shaped by transport planning, with the Energy Saving Trust publishing guidance for local authorities to advance low carbon design strategies. Sustainable urban development requires integration of mobility solutions with eco-design for buildings and green infrastructure. These measures influence building lifecycle performance and provide opportunities for net zero carbon buildings through coordinated planning.
Architectural projects are also driving awareness of environmental sustainability in construction. The planned Sustainability Hall in Taipei from architect Tadao Ando demonstrates how sustainable architecture can combine sustainable material specification with cultural value. It reinforces the role of sustainable building design in shaping public understanding of Whole Life Carbon Assessment and sustainable design.
Across these developments, industry leaders emphasise the need for lifecycle assessment and life cycle thinking in construction to ensure transparent benchmarks. From embodied carbon measurement to life cycle cost analysis, the sector is defining pathways toward carbon neutral construction. The alignment of finance, design innovation, and circular economy strategies is demonstrating that green construction and eco-friendly construction are becoming both achievable and commercially sustainable.
