Hill aides struggle to shun fossil fuel investments

Many of the congressional aides and federal agency staffers working to combat climate change are also investing for retirement in companies that are making the problem worse.

That's because the U.S. government only provides a few tax-deferred stock market investment options for its civil servants and uniformed service members through its Thrift Savings Plan, or TSP.

All of those funds appear to contain substantial holdings in businesses that produce or burn vast quantities of planet-warming fossil fuels, according to an analysis conducted for E&E News by As You Sow, a nonprofit that advocates for corporate environmental and social responsibility.
