Green bond refinancing and impact claims for a building retrofit
A Hong Kong property owner plans a HKD 1.5 billion green bond. Use of proceeds is 60% to refinance chillers installed in 2023, 25% for new lighting and building automation, and 15% for general working capital. The chiller project cost HKD 900 million and cut the building's energy intensity by 18% against a 2019 baseline. The new lighting and controls will cost HKD 375 million and are expected to cut electricity use by a further 9%. The building remains connected to the local grid. The issuer wants to report 'avoided emissions' for the entire building using a market-based grid factor and to count the chiller savings from 2023 onwards, even though the project was completed before the bond. The bond proceeds for working capital will be used for payroll and supplier payments. The issuer's adviser says refinancing is common and the bond can still be called green if the overall story is positive.
1. Assess the eligibility of each use-of-proceeds category and the overall green bond label.
Read the worked answer
The new lighting and building automation are clearly eligible as energy-efficiency improvements. The chiller refinancing can be eligible under the Green Bond Principles if the project meets the issuer's eligibility criteria, has a clear environmental benefit and falls within a disclosed lookback period. Because the chillers were installed in 2023, the issuer must disclose the lookback period and confirm the project is still operating and not already refinanced by another green instrument. The 15% working capital for payroll and supplier payments is not eligible. A bond with a material non-eligible tranche should not be marketed as a pure green bond. The issuer should either downsize the bond to the eligible amount, substitute other eligible projects for the working capital portion, or label it as a sustainability bond with clear allocation. Calling the whole bond green because the overall story is positive is not sufficient.
2. Evaluate the proposed impact reporting, including additionality and avoided emissions.

The issuer should report project-level impacts, not the entire building's avoided emissions. The chiller project was completed before the bond, so the bond does not create the 2023 savings; refinancing can still be eligible, but the impact claim must not imply new additionality. Counting savings from 2023 onwards may double count if the baseline already reflects the chillers or if the building's energy intensity changed for other reasons. The lighting and controls should report actual electricity savings against a verified baseline, with assumptions on operating hours and occupancy. For emissions, the issuer should use a location-based grid factor unless it has contractual instruments that justify a market-based factor. It should disclose kWh saved, tCO2e avoided, methodology, boundary and any rebound effects. Third-party verification would strengthen credibility.
3. How should the issuer structure allocation and reporting to avoid greenwashing risk?
Read the worked answer
The issuer should set up a ring-fenced ledger and allocate only the HKD 1.275 billion of eligible expenditure unless it identifies additional eligible projects. It should disclose the split between refinancing and new financing, the lookback period and the selection criteria. Annual allocation reports should show proceeds received, allocated, unallocated and temporarily invested. Impact reports should cover each project, the baseline, methodology, actual versus expected savings and assurance. The working capital tranche should be removed or clearly separated in a non-green tranche. The issuer should obtain a second-party opinion on the framework and an annual limited assurance review. It should avoid phrases such as 'carbon neutral building' or 'net-zero bond' unless those claims are separately substantiated. Clear boundaries and honest treatment of refinancing are more defensible than an optimistic overall narrative.
