Among this nation’s cities, the power of the purse to shape policy is perhaps the strongest in New York City, which has a pension fund worth more than $273 billion that it invests in industries that reflect the values of the city government. Earlier this year, Comptroller Scott Stringer invested $8 billion in projects related to the Green New Deal, which failed in Congress but was promoted by its progressive members. In line with its environmental vision, the city also divested $4 billion from fossil fuel companies.
