The University of California announced Tuesday that it has fully divested from all fossil fuels, the nation’s largest educational institution to do so as campaigns to fight climate change through investment strategies proliferate at campuses across the country.

The UC milestone capped a five-year effort to move the public research university system’s $126-billion portfolio into more environmentally sustainable investments, such as wind and solar energy. UC officials say their strategy is grounded in concerns about the planet’s future and in what makes financial sense.
