Explanation: Although ESG and SRI are similar concepts, they have different definitions.
ESG is a measure of a company's environmental (e.g. climate, waste, energy), social (human rights, labor and safety practices) and governance (transparency, diversity) record. ESG scores allow potential investors to gauge a company's commitment to socially responsible practices.
SRI stands for socially responsible investing. It is the practice of using negative and positive screens to determine what - and what not - to invest in. If an investor only wants to invest in companies with favorable ESG scores, or wants to ensure that she is not invested in tobacco or firearms, she is practicing socially responsible investing.
