IRRI provides evidence-based market research and actionable insights into sustainable investment, its research value chain, issues of interest to investors and company-to-investor communications practices.

IRRI is a joint-venture between Institutional Investor Research and SRI-Connect to deliver market intelligence on the sustainable investment value chain. We conduct primary research (including the waterfront IRRI Survey) and publicise the work of others on the size of sustainable investment globally, the economics & dynamics of the sustainable investment research value chain, best and current practice in sustainable investor communications by companies and issues of priority interest to sustainable investors

We gather and present these insights free-to-air to support the efficient development of investment & research products and services that factor sustainability considerations into investment decision-making and capital allocation.

The programme

IRRI is a joint venture market research programme between II Research and SRI-Connect to improve understanding of the economics and dynamics of the sustainable investment value chain. Over the past 10 years the programme has delivered a series of ‘IRRI Surveys’ and delivered a number of bespoke market research projects.

The IRRI Survey

The IRRI Survey is the annual, globally-authoritative, 360° practitioner-based review of leadership and innovation in sustainable investment and corporate governance.

It recognises and rewards best practice in sustainable investment research and reports on trends, opinions and developments within sustainable investment and corporate governance research

Bespoke research

We also conduct bespoke research to help asset managers develop their investment research capacity, to inform the strategy development of research providers and to help companies communicate effectively on sustainability to investors

Numerous investment firms now conduct and publish research on the size, development and trends within ESG and sustainable investment.  We believe, however, that this is the only platform that gathers these different sources together into one place with the explicit objective of supporting the growth and evolution of the sustainable investment industry.

We fully welcome the breadth and diversity of such research, will always highlight sources and provide links to research that we do not conduct ourselves and invite anyone with research that they would like to be presented on this platform, to contact Mike Tyrrell.
