Exploring nature-positive buildings. Understanding the role of buildings in the transition to a nature-positive future
The Role of the Built Environment
The built environment sector plays a crucial role in achieving a nature-positive future. It is responsible for nearly 30% of global biodiversity loss, 50% of raw materials extraction, 40% of waste generation, and 40% of CO2 emissions.
Projected Waste Generation
By 2025, the construction industry is projected to produce 2.2 billion tonnes of waste each year. Approximately 77 million tonnes (35%) of this waste will end up in landfills annually.
Research on Nature Impacts
To address these issues, the World Business Council for Sustainable Development (WBCSD), in collaboration with its members and Arup, has launched research on the nature impacts of buildings throughout their lifecycle. The report, Exploring Nature Positive Buildings, provides essential steps for real estate developers and building designers.
Key Messages for Developers
The report outlines four key messages for reducing the ecological footprint of buildings:
- Think Global
Acknowledge the significant impacts of material extraction and processing, which occur far from the building site. - Consider Whole Lifecycle
Assess the embodied nature impacts of a building throughout its entire life, alongside on-site impacts. - Take Immediate Action
Implement actionable steps now, such as adopting circular economy principles to minimise raw material extraction. - Engage with the Value Chain
Collaborate across the sector to better understand nature impacts. Work together to change standards, advocate for policy changes, and drive meaningful progress.
Conclusion
By following these guidelines, the built environment sector can contribute significantly to a sustainable and nature-positive future.
