Our goal

We want to increase the flow of public and private capital to address environmental and social challenges. Those capital flows are vital in achieving the transition to a net-zero carbon world, which should be inclusive and socially beneficial – a concept commonly referred to as a ‘just transition’. 

What we have done to achieve it

With the backing of a large group of leading investors and industry bodies, we developed a joint proposal for a UK Green+ Gilt, a sovereign bond combining social with environmental impact.

The coronavirus pandemic has shown that the need to address both the consequences of climate change and the social impact of a transition to a net-zero economy has never been more important. Our Green+ Gilt proposal argues that environmentally sound investments should also create high-quality jobs and skills and contribute to “levelling up” regional inequalities in the UK, with local solutions targeting deprived areas and communities.

Market appetite for bonds combining social with environmental impact

The proposal was developed in partnership with the Green Finance Institute and the London School of Economics’ Grantham Research Institute on Climate Change and the Environment, and with input from fixed income market participants. It also gained the support of 40 leading asset owners and managers, representing more than £10 trillion in assets, as well as influential professional bodies. In October 2020, shortly after the publication of our proposal, the UK government announced its plan to issue the first of a series of green bonds in 2021.

To build on the success of our Green+ work and help address the need for the sovereign green bond to deliver jobs, skills and levelling up, we have established a working group to develop robust and measurable metrics for these social impacts that could be used in the design process.


Our paper, “The Green+ Bond: How EU Sovereign and Corporate Issuers could deliver Green Sovereign Bonds with Social Co-Benefits”, co-authored with the LSE’s Grantham Research Institute, emphasises the strategic potential for a green sovereign bond with well-defined social and economic benefits to support the European Commission’s new Strategy for “financing the transition to a sustainable economy.”

In September 2021, the Institute submitted its response to the Financial Conduct Authority’s consultation papers CP21/17 and CP21/18 on enhancing climate-related disclosures. The Institute strongly welcomes these timely consultations and the FCA’s commitment to widening the applicability of its requirement to make climate-related disclosures.

In July 2021, the Platform on Sustainable Finance published its first draft report on a proposal for a social taxonomy, which assesses the merits of a social taxonomy in addition to the green taxonomy, and explores possible avenues to complement the existing taxonomy. The Institute strongly welcomes the EU’s foresight in developing a social taxonomy in addition to the green taxonomy and, in August 2021, the Institute submitted its response to the Platform’s consultation on the draft report. The document in this post outlines the key excerpts from our response.
