Green Bonds Certification

The Carbon Trust is the leading expert in assessing green projects and can provide a credible independent view to help inform decision-making in connection with green bonds.

Green Bonds are created to fund new and existing projects that have positive environmental and climate benefits. Proceeds from these bonds are earmarked for projects that address the issue of climate change or have other environmental benefits. Investment projects may include renewable energy, low carbon buildings, industrial energy efficiency, waste management, transport improvements or water management.

Climate Bond Certified

There’s a growing demand for independent assessments of green bonds by a recognised leader in the field of carbon reduction and environmental sustainability. This demand is led by the need to provide credibility and confidence that investments in green bonds have a genuine environmental benefit.

The Carbon Trust is the leading expert in assessing green projects and can provide a credible independent view to help inform decision-making in connection with green bonds. We can help you develop a framework for assessing the environmental impact of green projects and provide a comprehensive assessment and report on the green credentials and impact of projects.


Green bonds offer a range of benefits, not least of which is that they allow corporate bonds to be linked with low carbon activities of the issuer.

A liquid market of impactful green bonds also allows investors to:

  • Proactively hedge against future environmental and climate change risks
  • Publicly declare their appetite for green deal-flow
  • Signal their willingness to invest in the green economy.


We can help you

  • Review your sustainability strategy and the “green” nature of investments
  • Analyse green projects and help you define suitable green investments
  • Develop a methodology to analyse the green impact against suitable KPIs
  • Ensure you have the right tools to develop or analyse the green elements of bonds and track their environmental performance
  • Provide opinions in connection with recognised green bond standards

Carbon Trust Certification is acknowledged as a leading provider of independent assurance and certification services that recognise real achievements in sustainability. Having developed the world’s first certification for organisational greenhouse gas emissions, we offer authoritative advice and verification of green bonds that provides confidence to issuers and investors alike.

The global transition to a low carbon economy is going to require very significant amounts of capital. To make this money available it is going to be critical to engage with the financial sector and develop investment products that have a genuine impact on climate change. Independent verification of bonds to external standards is a real step forward in this process, so we are pleased to be working with the Climate Bonds Initiative to help advance this important new area.

Morgan Jones, Associate Director of Certification, Carbon Trust

To address climate change, we need to ensure capital flows to green projects at scale and speed. The rapid growth of the green bond market has proven that there is strong investor demand for investment in climate change related assets. Now we need to generate more investment opportunities that can address climate change and meet investor demand, which will mean green bond issuance in the $ trillions. The Carbon Trust has a fantastic reputation for its work in sustainable assets. Now, as a licensed verifier under the Climate Bonds Standard, I am delighted that it is bringing that expertise to this urgent and growing market.
