"A commonly held belief among investors is that impact investing-adding environmental, social or governance criteria to the investment selection process-will require a trade-off in performance. Though this may have been true in the early days of impact investing, the space has evolved significantly in the last decade.
In this paper, we will evaluate current impact investing by examining:
- What impact investing is and how it has evolved to be a viable investment approach
- How investors can maintain returns in their portfolios while investing for impact
- How impact investing can be used to identify risks and opportunities in the market
- Historical returns from a range of impact investments
- How investors can start accessing the impact investing marketplace today"

"This report from Oxfam and Sumerian Partners questions some of the assumptions around impact investment and highlights the experience of enterprises contributing to poverty reduction so that they might be better served by the field. It argues that the sector risks being discredited due to rising, unrealistic expectations about financial returns."

"The world is on the brink of a revolution in how we solve society's toughest problems. The force driving this revolution is "impact investing", which harnesses entrepreneurship, innovation and capital to power social progress. This report, Impact Investing: The Invisible Heart of Markets - Harnessing the power of entrepreneurship, innovation and capital for public good, examines what is needed to catalyse the growth of a global market for impact investment. It makes recommendations that can be implemented across Taskforce countries and beyond to deliver better social outcomes and improve millions of lives across the world. The report calls on governments and the financial sector to take action to unleash $1 trillion of private sector impact investment to tackle social problems."

"The study reviews the current state of impact investments in Singapore and Hong Kong, particularly those that have engaged with foundations. It further looks at the trends and challenges of the impact investment sector before presenting a list of recommendations."

"This research note asserts that impact investment, which is intended to create positive social or environmental impact beyond financial return, constitutes a new asset class. The report also includes the first large-scale data analysis of return expectations from more than 1,000 impact investments and compares them to established benchmarks for emerging and developed market debt and equity returns. We hope this report helps to advance a broader understanding of impact investing as an appropriate and economically effective way to complement government and philanthropy in solving the world's greatest problems at scale."

"Unitus Seed Fund has published a guide that has combined the methodology and approach the organization applied to designing to an impact measurement framework and consists of templates by sector for multiple types of businesses that can be downloaded for use."

"The following document presents five case studies to demonstrate how a diverse group of organizations have developed sound impact measurement practices, including how the seven guidelines are being applied in the organization, as well as the organization’s impact measurement practices, the contextual factors that shaped their impact measurement approach, how they involved key stakeholders along the way, and key “impact measurement lessons.” These case studies – which are highly diverse in nature – aim to help investors and investees translate the seven guidelines for impact measurement into an impact measurement approach that is right for them."

"This handbook provides investors, businesses and private sector development practitioners with an overview of tools and methods for effective and appropriately tailored data collection for impact measurement and management. It builds on the recognition that the methods of larger, independent impact evaluations of, for example, government-funded programmes rarely lend themselves well to a private sector context. In reviewing select private sector-relevant tools and methods, it draws out how such tools can deliver impact insights while often feeding valuable business intelligence back into companies."

"Impact Investing: A Framework for Policy Design and Analysis represents a framework for thinking about the role government policy can play in creating an enabling environment for impact investing. The report answers the question, "How can policymakers, investors, and civil society better develop and analyze impact investing policies?"

This report presents three tools in order to lay the groundwork for future research: a model for locating the role of government in impact investing markets; a set of criteria that offer a practical starting point for the design and evaluation of policy; and sixteen case studies that provide detailed insight into a range of policies around the world."

"Impact assessment is a key component of managing an impact investment portfolio, and many investors today are building methodologies that bring value
beyond simply reporting outcomes.

For many investors, the impact goal is the common thread across a portfolio of various sector, geography and instrument types and this diversification can make choosing an impact assessment methodology challenging. As such, the process for developing a methodology is often an iterative one, refined with experience and data over time.

To help inform that iterative process, this research presents sixty-eight case studies from twenty-one leading impact investors that share best practice and
debated viewpoints on impact assessment along the investment process."
