SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Retirement Investments for a 
Sustainable Economy Act of 2018'' or the ``RISE Act of 2018''.

SEC. 2. SENSE OF CONGRESS.

    It is the sense of Congress that--
            (1) continued inaction by the Federal Government with 
        respect to addressing climate change poses a significant threat 
        to the growth and stability of the economy and population of 
        the United States;
            (2) pension and retirement funds are vulnerable to distinct 
        risks relating to climate change, including--
                    (A) climate impact risks, including sea level rise, 
                heat waves, desertification, ocean acidification, 
                flooding, drought, extreme weather, and wildfires;
                    (B) carbon-constrained demand risks, including 
                stranded carbon assets, which financial institutions 
                have estimated as having a value of 
                $100,000,000,000,000; and
                    (C) climate liability risks, including from 
                evolving interpretations of fiduciary and tortious 
                duties of care; and
            (3) assessing the potential impact of climate-related risks 
        on national and international financial systems, including 
        retirement savings accounts and pensions, is an urgent concern.

                determined by dividing the aggregate market value of 
                all shares of that stock by the aggregate market value 
                of all shares of all stocks included in the index 
                selected under subparagraph (A); and
                    ``(iii) to ensure that no investment in the

                fuel entity.''.

SEC. 4. GOVERNMENT ACCOUNTABILITY OFFICE REPORT.

    (a) Definition.--In this section, the term ``fossil fuel entity'' 
has the meaning given the term in section 8438(a) of title 5, United 
States Code, as amended by this Act.
    (b) Report.--Not later than 1 year after the date of enactment of 
this Act, the Comptroller General of the United States shall submit to 
Congress a report that--
            (1) analyzes, as of that date of enactment--
                    (A) the proportion of the stocks, bonds, and other 
                obligations held by the Thrift Savings Fund that are 
                stocks, bonds, or other obligations of a fossil fuel 
                entity; and
                    (B) the effect on individuals holding accounts in 
                the Thrift Savings Fund of the Thrift Savings Fund 
                holding stocks, bonds, or other obligations of fossil 
                fuel entities under the climate policies that would be 
                needed to limit global temperature increase to 2 
                degrees Celsius, given technology that is available and 
                economically feasible as of that date of enactment; and
            (2) provides a plan and mechanism that would allow the 
        Federal Retirement Thrift Investment Board to divest from 
        fossil fuel entities to prevent or mitigate any negative 
        investment risk on individuals holding accounts in the Thrift 
        Savings Fund.
