Water is vital to human and planetary health and the internationally agreed goals that back it, including the 2030 Agenda for Sustainable Development, the Kunming-Montreal Global Biodiversity Framework, the Sendai Framework and the Paris Agreement. Yet the triple planetary crisis – the crisis of climate change, nature and biodiversity loss and pollution and waste – is affecting the availability, distribution, quality and quantity of water. Despite water being essential for human health, food security, energy supplies, sustaining cities, and ecosystems and on the front lines of the triple planetary crisis of climate change, biodiversity loss, and pollution, SDG 6 is alarmingly off-track. For most of the SDG 6 Indicators, the current rate of progress is not fast enough to close the gap before 2030. In some cases, progress is even relapsing. The new mid-term status reports for SDG 6 indicators: 6.3.2, 6.5.1, and 6.6.1 found that if the priorities under SDG 6 are to be achieved by 2030, action on these indicators needs to be accelerated four times faster. These priorities can be ensured if adequate investments are made towards institutions, infrastructure, information, and innovation, where concerted action and institutional coherence is required, and new ideas, tools, and solutions are developed that draw from existing knowledge and indigenous practices. Working with partners within the framework of the UN-Water led Integrated Monitoring Initiative for SDG 6, UNEP officially launched reports, in August 2021, on the three SDG 6 indicators for which it is custodian. These indicator reports are: SDG 6.3.2 – Progress on Ambient Water Quality with a special focus on Health SDG 6.5.1 – Progress on the Implementation of Integrated Water Resources Management with special focus on Climate Change SDG 6.6.1 – Progress on Water-related Ecosystems with a special focus on Biodiversity A key underlying message from these reports is that existing efforts to protect and restore water-related ecosystems must be urgently scaled up and accelerated. Progress Reports can also be found on UN-Water's SDG 6 Progress Reports page
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.
