What We Do

We evaluate and verify how clients approach the impact in impact investing based on accepted industry standards. BlueMark’s verification services are designed to strengthen confidence in investors’ impact practices and results. Our services are structured around two key pillars of accountability for impact:

  • Impact Management Practice: the systems and processes used by an investor or company to manage their impact
  • Impact Performance: the reporting approach used by an investor or company to communicate their impact strategy, goals and results

The market’s understanding of what constitutes strong impact management practice has advanced considerably in recent years, thanks to standards like the Operating Principles for Impact Management and SDG Impact as well as the field-building work of the Impact Management Project. While standards for impact performance reporting are still in development, there are a number of foundational frameworks that BlueMark draws on to provide clients a diagnostic assessment of the quality and completeness of their impact performance reporting.

In the coming years, we expect the market will evolve towards disclosure and reporting standards for investors and companies that combine elements of both practice and performance and that BlueMark’s services will evolve accordingly.

Overview of BlueMark’s Impact Verification Services

BlueMark’s verification services are relevant for asset managers, asset allocators, and companies. Our verification approach is designed to be highly efficient for clients and our engagements are typically conducted over four to six weeks. The BlueMark verification process starts with document collection and interviews. The BlueMark team then conducts an in-depth assessment of the information provided. Finally, each engagement results in a publishable independent verifier statement as well as a detailed report for the client’s internal use including custom insights, recommendations, and benchmark analyses where applicable.

We analyze the compliance, quality, and depth of a client’s impact management systems and processes against key market standards.

Our mandate verification is a rigorous ex-ante evaluation of an investor or company’s impact strategy.

We evaluate the clarity of an investor’s impact thesis, its alignment with goal-setting and metrics standards, and the strength of supporting evidence.

Our reporting verification is a thorough analysis of an investor or company’s ex-post impact performance results.

We evaluate the relevance, comparability, balance, and reliability of a client’s reported impact information.

Our Verification Methodology

We developed our verification methodology to meet the growing investor demand and market expectation for greater reliability and credibility in the impact label, especially as impact claims are more closely scrutinized by a range of stakeholders. Our approach to verification is designed to bring three specific benefits to the impact investing market:



By evaluating whether impact investors’ practices and performance are aligned to accepted market standards


By encouraging transparency, adoption of industry best practices, and shared learning that continuously raises the bar for performance


By establishing benchmarks and ratings that allow stakeholders to compare different approaches to impact investing on a consistent basis

We believe these three benefits are essential to scaling the impact investing industry with integrity and are embedded in how we approach each verification assignment. We draw on a number of impact investing industry standards in conducting our verifications, including those below:

We also draw on several financial regulations, including:

EBRD has been doing impact investing for more than two decades, but we knew there was more we could learn about how to improve our impact management system. BlueMark brought extensive experience and a well-regarded approach to verification that quickly and effectively assessed the policies, processes and tools that we use for impact management. The BlueMark verification process confirmed several areas of strength, but also highlighted specific areas where EBRD could go further, going beyond simple compliance to benchmarking our impact performance against other industry leaders in impact investing and better positioning us to attract more private impact capital for development.

On May 13th, 2021, BlueMark welcomed impact investing leaders and experts for a virtual event on How to Be an Impact Leader, which featured a conversation on the importance of benchmarking and how a shared understanding of opportunities and challenges can advance the field. Speakers included: Tomi Amosun (Summit Africa), Elizabeth Boggs-Davidsen (U.S. International Development Finance Corporation), Cecilia Chao (Bain Capital Double Impact), Maria Kozloski (The Rockefeller Foundation), and Jeremy Rogers (Big Society Capital).



In 2018 KKR launched its first dedicated impact investing fund, KKR Global Impact, and, in April 2019, became a founding Signatory to the Operating Principles for Impact Management. The firm recognized that any credible impact investor would need a rigorous approach to assessing and managing impact, and embraced the idea of disclosure and independent verification of its impact management system. In an IFC report, New Insights Into the Practice of Impact Investing, KKR said that the firm “believed that impact accountability is key to scaling the impact investing industry” – not just for the sake of disclosure, “but rather using disclosure and verification to help drive continuous improvement.”

KKR engaged BlueMark to perform the assessment and shared findings that assessed progress to date and provided recommendations on how to further build on the Fund’s work. Given that the external assessment occurred early in the life of KKR’s strategy, the Fund was able to use BlueMark’s insights to help inform the development of its impact management processes, post-investment. For example, KKR built additional impact management considerations into its existing Portfolio Management Committee materials to revisit a transaction’s impact thesis and risks over time and, in 2019, completed an assurance readiness exercise to evaluate its data management and controls procedures.
