CONGRESSIONAL VOTES ON BILLS

League of Conservation Voters has archives of congressional votes on environmental issues since 1971. Each year, LCV scores the voting records of individual members of Congress, which are detailed in their annual report. Their website includes those reports and interactive charts to explore the history of congressional voting on environmental issues.
