Socially responsible investing (SRI), or social investment, also known as sustainable, socially conscious, "green" or ethical investing, is any investment strategy which seeks to consider both financial return and social/environmental good to bring about social change regarded as positive by proponents.

Recently, it has also become known as "sustainable investing" or "responsible investing". There is also a subset of SRI known as "impact investing", devoted to the conscious creation of social impact through investment.

In general, socially responsible investors encourage corporate practices that they believe promote environmental stewardship, consumer protection, human rights, and racial or gender diversity.
