All 11 members of Massachusetts' congressional delegation received high marks for their votes on environment-related policies in 2017 -- ranking the state among the top in the country on such issues, the League of Conservation Voters announced this week.
The advocacy organization, which released its latest National Environmental Scorecard Tuesday, gave seven of the state's congressional lawmakers perfect scores in 2017.
Massachusetts' remaining four members of Congress, meanwhile, took "pro-environment" votes 89 percent of the time last year or more, the League found.
The 2017 scorecard, which the LCV cast as "the primary yardstick for evaluating the environmental records of every member of Congress," looks at how lawmakers voted on 19 issues in the U.S. Senate and 35 issues in the U.S. House of Representatives.
Those votes, the League noted, included ballots cast on Trump administration officials and judicial nominations, a GOP-backed tax overhaul package, regulatory changes and other standalone bills.
In the Senate, U.S. Sen. Elizabeth Warren was among more than two dozen Democrats who earned a perfect score of 100 percent for their "pro-environment action" in 2017, according to the LCV scorecard.
The League, meanwhile, gave U.S. Sen. Ed Markey a 95 percent score for 2017, noting that the Massachusetts Democrat was absent for a Feb. 3, 2017 vote on a resolution that it called an "assault on the anti-corruption rule for fossil fuel companies."
In the House, six members of the Massachusetts delegation also received perfect marks on the LCV's 2017 scorecard, including U.S. Reps. Richard Neal, D-Springfield; Jim McGovern, D-Worcester; Seth Moulton, D-Salem; Michael Capuano, D-Somerville; Stephen Lynch, D-South Boston; and Bill Keating, D-Bourne.
Congresswoman Niki Tsongas, D-Lowell, and U.S. Rep. Joe Kennedy III, D-Brookline, meanwhile, saw respective scores of 91 and 94 percent after missing a handful of votes on bills cited in the LCV's scorecard.
The League gave U.S. Rep. Katherine Clark, D-Melrose, a score of 89 percent for missing votes on various environment-related measures used to craft a lawmaker's score.
The group, however, noted that the congresswoman entered a statement into the Congressional Record clarifying how she would have voted on one of the pieces of legislation -- a position which LCV said "would have been scored as pro-environment."
The representatives' scores helped Massachusetts' House delegation rank second in the country behind Rhode Island on environmental issues. It tied Delaware, New Hampshire and Vermont with an average score of 97 percent.
The Massachusetts lawmakers' high marks came despite what the LCV Senior Vice President for Government Affairs Tiernan Sittenfeld cast as Republican congressional leaders' refusal "to stand up to President (Donald) Trump's extreme anti-environmental agenda and his attacks on our air, water, land and wildlife."
The League noted that 124 House and 46 Senate Republicans received marks of 0 percent on the 2017 scorecard. By contrast, 27 Senate and 84 House Democrats earned perfect scores on the LCV scorecard.
On average, House Republicans received a score of 5 percent, compared to their Democratic counterparts' average score of 94 percent. Senate Republicans averaged even lower, at just 1 percent, while Democrats voted "pro-environment" an average of 93 percent of the time, the scorecard found.
The League has published its annual National Environmental Scorecard, which officials said "represents the consensus of experts from about 20 respected environmental and conservation organizations," every year since 1970.
