The next building block for impact investing: quality impact reporting

The impact investing industry has matured over the past couple of years, especially when it comes to aligning investors around common standards for disciplined impact management practices.

The Operating Principles for Impact Management (OPIM) and the forthcoming SDG Impact Standards from UNDP, in particular, have created both clarity around the practices required to authentically integrate impact into each stage of the investment process and accountability for those practices through the encouragement or requirement of independent verification.

And yet with each advancement, another missing building block in the impact investment market is revealed. Attention has shifted to the imperative of impact performance reporting standards and, as with impact management practices, both clear standards and a mechanism for accountability are needed. Recent publications by leading sustainability and integrated reporting organizations like CDP, CDSB, GRI, IIRC and SASB; the IFRS Foundation; and the Global Impact Investing Network (GIIN) reflect efforts to define and harmonize both corporate and investor reporting standards. 

Impact performance reports today come in all sizes and flavors, reflecting a lack of clarity and consensus on what constitutes quality impact reporting as well as efforts by individual investors to convey their own “secret sauce.” The state of play makes it difficult for asset owners and allocators to interpret the impact performance of their investments, much less to compare one impact fund to another.

Investors are in search of a better approach to impact reporting that incorporates relevant impact goals and metrics along with the qualitative information needed to communicate a holistic, yet digestible, portrayal of the impact of their portfolios. 

While we collectively strive for more consistency and standardization, it’s important to keep in mind that robust reporting—whether on impact or financial performance—is both an art and a science, a balance of both qualitative and quantitative information. Impact reporting will always involve a degree of subjectivity, which makes the role of expert, third-party evaluation and verification critical to ensuring accountability, discipline, and comparability, three core pillars of BlueMark’s approach.

Introducing a way to verify impact reporting

In the absence of a universal or harmonized set of impact reporting standards, BlueMark has stepped up to introduce an impact reporting verification service to respond to market demand. We welcome feedback and comments from market practitioners as we seek to continue to refine our methodology to best meet the market’s needs.

Our approach draws on several leading foundational frameworks, including the GRI’s Sustainability Reporting Standards, OPIM, Impact Management Project, IRIS+, and the SDGs, and encompasses both quantitative and qualitative information necessary for a complete and insightful picture of impact performance.

BlueMark’s approach is organized around five key characteristics of high-quality impact reporting. We can think about these elements as divided between two categories: the reporting framework, on the one hand, and the impact performance report, on the other. While an investor’s actual impact report may focus most heavily on the latter, both levels of information are needed for completeness.

Framework-level:

  1. Context – Impact reporting should be supported by robust and clearly articulated portfolio-level and investment-level impact theories of change, including an analysis of the evidence base for the linkages between stated impact goals, assumptions, target outputs, and outcomes. The investor’s particular contribution to achieving impact should also be clearly developed. 
  2. Relevance – The relevance of impact goals to the SDGs and underlying SDG Targets should be clearly established, drawing on industry frameworks such as the Impact Management Project’s A, B, C classification scheme. In addition, the reporting should take care to identify the stakeholders – including customers, the environment, local communities, and workers – who experience the positive and negative impacts of the investment strategy.

Performance report-level:

  1. Comparability – An impact report should use objective and transparent impact indicators, drawn wherever possible from industry standards, that allow for the analysis of impact performance over time, relative to expectations, and relative to other organizations. The proportionality of reported impact results to the scale of the investment should also be considered. 
  2. Balance – An impact report should feature a discussion of both positive and negative impacts as well as impact and ESG risks. To achieve true balance, the report should also discuss instances of impact underperformance and unintended impacts and what lessons were learned as a result.
  3. Reliability – Impact data, which may come from both primary and secondary sources, should be collected and tracked in a way that drives data quality. Quality control practices should help to ensure that reported impact data is free of manipulation or errors and consistently defined and calculated.

We believe that impact reporting that incorporates these elements is worthy of a high mark, and we look forward to sharing specific examples in future articles.

Given the lack of common standards and dearth of historical impact performance reporting, even the most experienced impact investors are likely to have gaps or shortcomings in their reporting processes. Independent verification of these reports and the underlying systems can help spotlight areas of strength and where there is room for improvement, thereby providing LPs and other stakeholders with the assurance they need while also encouraging investors’ continued advancement towards best practices. 

We see the future of impact reporting evolving in much the same way as financial reporting, with third-party verifiers such as BlueMark playing an important role in bringing greater accountability, discipline, and comparability to the market. As impact investors become more comfortable with reporting on a variety of both quantitative and qualitative inputs, the bar of ‘performance’ and best practices will rise across the industry.
