NEW YORK (AP) — Instead of lending to just the government or some faceless corporation, what if your bond mutual fund also helped to vaccinate kids around the world? Or helped finance a clean-water project or solar-energy farm?

More mutual fund managers are seeking out bonds that not only do well but also promote a positive impact on the environment, society and corporate governance. It’s a concept called socially responsible investing, and it’s long been dominated by stock mutual funds. But a proliferation of “green bonds,” whose proceeds go toward projects with environmental benefits, and similar investments mean more bond funds are using a socially responsible lens.
