Green Bond

A Green Bond is a debt security issued by a government, municipality, development bank, or corporation that commits to using 100 percent of the net proceeds to finance or refinance projects with defined environmental or climate benefits, subject to ongoing reporting that confirms the funds were used as stated.

What is a Green Bond?

The Green Bond market emerged from the EIB's Climate Awareness Bond in 2007 and has grown into a multi-trillion-dollar asset class. The International Capital Market Association's (ICMA) Green Bond Principles establish the voluntary market standard: proceeds must be allocated to an eligible green project category, the issuer must define a process for evaluating and selecting those projects, proceeds must be tracked in a dedicated account, and the issuer must report annually on allocation and environmental impact.

Development banks are major issuers. The World Bank, EIB, ADB, AfDB, and EBRD all issue green bonds and use the proceeds to finance climate and environmental projects in their lending portfolios. When a green bond finances a project, the downstream procurement for that project inherits the issuer's environmental reporting obligations, so suppliers may face additional monitoring and reporting requirements. The link between a green bond and a procurement notice is indirect but real: climate-finance derived from green-bond proceeds flows into project budgets that generate tenders for goods, works, and consulting services.

Why Green Bond matters for bidders

A supplier does not bid on a green bond itself, but knowing that a project is green-bond-financed tells you several things. The procuring entity has committed to external reporting on environmental impact, which means they are more likely to include environmental-criteria-in-evaluation and require measurable environmental performance milestones in the contract. Suppliers with certified green credentials, environmental reporting capability, or experience on other green-bond-financed projects can use this context to frame their proposals in terms the evaluating team recognises. Reference specific environmental outcomes, not just compliant processes.

FAQ

What is the difference between a green bond and a sustainability bond?

A green bond restricts proceeds to environmental and climate projects. A sustainability bond uses proceeds for a mix of green and social projects. A social bond restricts proceeds to social projects only.

Do suppliers need to do anything differently on green-bond-financed projects?

Not in the bidding process itself, but during contract execution suppliers may be required to provide data that allows the procuring entity to report on environmental outcomes to bond investors.

Which development banks are the largest green-bond issuers?

The EIB, World Bank, ADB, and AfDB are consistently among the largest multilateral green-bond issuers, collectively raising tens of billions of dollars annually.
