10. SBAT Target setting feature

11. Loss of biocapacity
• Biocapacity: The capacity of ecosystems to produce
useful biological materials and to absorb waste
materials generated by humans, using current
management schemes and extraction technologies.
Global Footprint Network

12. Recognising the benefits of biodiversity
United Nations Convention on Biological Diversity

13. Sustainable Building Assessment Tool:
Future Considerations
Increased emphasis on Biocapacity
• Promoting the use of grown materials
• Supporting the integration of ecosystems into development in order to
support local ecosystem services as well as the provision of food, health
and livelihoods
• Drawing on local indigenous knowledge
• Ensuring that local communities are involved in development and benefit
from this
Linked measures and positive feedback loops
• Demonstrate how addressing biocapacity can lead to improved social and
economic benefits
• Indicate how positive feedback loops could work: increasing biocapacity
leads to social and economic benefits, leads to reduced environmental
impacts, leads to improved biocapacity..
