The Climate Bonds Standard and Certification Scheme is a labelling scheme for Entities, Assets and Debt Instruments. Rigorous scientific criteria ensure that Certified investments in climate mitigation are consistent with the 1.5owarming limit in the Paris Agreement. The Scheme is used globally by bond issuers, governments, investors and the financial markets to prioritise investments which genuinely contribute to addressing climate change.

Buildings Upgrade


For an Buildings Upgrade project to qualify for Climate Bonds Certification, it has to achieve a CO2 emissions reduction target determined by the term of the bond. For a 5-year bond, the CO2 emissions reduction target is 30%. For a 30-year bond, the target is 50%. (see chart below)

For example, if a building currently emits 795tCO2/year and a 30 year bond will finance upgrades which are modelled to deliver a 180tCO2 saving from lighting related emissions and a 220tCO2 saving from HVAC related emissions, the percentage CO2 emissions reduction is 50% and the bond qualifies for Climate Bonds Certification.

When a bond is submitted for application for Certification, which involves building retrofits / upgrades, the Low Carbon Buildings Technical Working Group may need to review the proposed methodology for calculating the CO2 emissions reductions.

Further details on the Upgrade criteria are found in the menu on the right.

The chart below indicates the CO2 emissions targets for different bond terms from 5 years to 30 years.
