• 25 members
• Develop guideline on scope of
building passport (living document).
• Assess possible cross-task
cooperation on data relevant issues
(for example science-based targets).

4. Context

• What are the options for funding and
promoting/granting sustainable development?
• What information and evidence must be provided?
• Which instruments can be used to communicate
information from the architect/ designer/ urban
planner/sustainability assessor to the bank/funding
agency?

• GABC Work Area 5 will generate practical guidelines
for Building Passports to be presented at COP 26 in
Glasgow in 2021
• The work of the GABC will be accompanied by the
work of a wider task force around the topic
• Case studies are very welcome. If you feel you
have one, please get in touch!
