Climate Bonds Certification surges past USD300bn milestone in 2023: driving green finance forward

Expanding scope from energy to infrastructure: Certification for individual debt instruments to whole entities: one global standard applicable across diverse jurisdictions, sectors, and instruments for a greener future

By the close of 2023, Certified Climate Bonds have reached USD 300 billion, reflecting the Climate Bonds Standard and Certification Scheme’s role in setting benchmarks for climate investment.

This figure extends over 16 sectors and 20 types of debt instruments (inlcuding bonds, project bonds, securitisation bonds, loans, green deposits, green repos, commercial paper, CRA, RMBS, sukuk, revolving credit facilities, convertible bonds, covered bonds, private placement, to name a few), highlighting the broad applicability and growth of the Climate Bonds Standard.

The Climate Bonds Standard, with certifications in 52 countries from 294 issuers, covers an extensive array of climate-focused debt instruments. This includes sovereign and sub-sovereign bonds, prominent banks, and major issuers in sectors such as transport, energy, buildings, and water, reflecting its broad sectoral adoption.


2023: Expansion of Climate Bonds Standard with Version 4.0 and Beyond

Building on the momentum of reaching USD 300 billion milestone in certified bonds, 2023 was a landmark year for the Climate Bonds Standard. The release of Standard Version 4.0 marked a significant 'structural expansion' of our certification scheme. This evolution has broadened the scope far beyond traditional debt instruments such as green bonds and sustainability-linked bonds (SLBs). For the first time, entire company entities can now be certified, revolutionising the way organisations can demonstrate their green credentials. For the first time, companies as a whole can achieve certification, ensuring their entire operations adhere to the best practice standards in the market.

This holistic approach provides investors with a more comprehensive assurance that their investments are not only supporting individual green projects but are also backing entities wholly committed to sustainable practices. This entity-wide certification serves as a robust indicator of genuine, across-the-board adherence to green principles, offering investors a higher level of confidence in the legitimacy and impact of their sustainable investments.

Moreover, 2023 saw the Climate Bonds Standard extend its reach not only across various debt instruments and entity certification but also into more diverse sectors. This included hard-to-abate sectors like Cement, Chemicals, Hydrogen, and Steel, which are critical to global decarbonisation efforts. In addition, we are gearing up to introduce new criteria for Deforestation and Conversion FreeAgri-Crop and LivestockElectrical Utilities and Critical Raw Materials.

This expansion reflects our commitment to continuously evolving and adapting to the needs of a rapidly changing global environment, ensuring that the Climate Bonds Standard remains at the forefront of sustainable finance.
