While impact investing has become a buzzword in global development in recent years, the concept and practice had been around for decades before the sector even had a name. To take one perhaps under-recognized example, Mennonite Economic Development Associates (MEDA) was launched as an investment club in 1953, when a group of North American Mennonite business people joined together to support the development of businesses in Paraguay, Uruguay and Argentina.
ESG investing is when one uses environmental, social and governance (ESG) criteria during the portfolio construction and/or analysis processes. ESG investing came out of the field of socially responsible investing (SRI).
Arguably, SRI can be used as an umbrella term for many buzz terms: ESG investing, impact investing, ethical investing, values based investing, green investing, among others. The important similarity is they approach investing through some form of environmental, social, or corporate governance perspective.
