When Women Lead

Women's Environmental Voting Records in Congress, 2006-2018

In 2014, women surpassed more than 100 seats in Congress for the first time in history; a symbolic milestone in the long struggle for women’s equality in US government. Today, in 2019, women hold 127 seats in Congress. Despite these gains, it will still take more than century at our current rate for our legislature to achieve equal representation.

Statistics conveyed by organizations like the Center for American Women in Politics and the Institute for Women’s Policy Research highlight this disparity: women comprise roughly 51 percent of the population and 53 percent of the electorate but only 24 percent of Congress. Women are not the only constituency impacted by unequal representation – our entire policymaking process suffers.

Since 2000, Rachel’s Network has made the case that gender disparity in government not only stymies equality, it has serious implications for environmental policy as well.


“We need to have more women in Congress — we need more consensus-builders, we need people who will listen more, who are less ego-driven and partisan. I really believe if you had 51 percent women in Congress, the whole dynamic would change.”

Senator Kirsten Gillibrand (D-NY)

In previous iterations of our report When Women Lead (in 2003 and 2011), we analyzed the voting records of federal legislators going as far back as 1983 using League of Conservation Voters (LCV) Environmental Scorecard data. We found that women in Congress vote for legislation supporting clean air, clean water, renewable energy, climate action, and public health much more often than their male counterparts (and similarly vote more often against legislation that would roll back these protections).

This update brings our analysis up to the present. After comparing annual LCV scores each year from 2006-2018, we again found that women legislators vote for environmental protections more often than their male counterparts in both the House and Senate.

Climate change, pollution, food and energy insecurity, chemical safety, and biodiversity loss have become urgent global concerns that threaten lives and livelihoods in the US. If we want to make progress on protecting the environment and public health, we should help elect more women to public office, and support them during their tenure.

Research from the European Journal of Political Economy found that female representation in national legislatures leads countries to adopt more stringent climate change policies. 

In a 2016 survey from the Pew Research Center, 57 percent of women in the US said that the environment was important to them in the next election, compared to 47 percent of men. Pew also found that women are more likely than men to say climate change is a major threat by a margin of 15 points.

Women’s Environmental Voting Records in the House of Representatives



Since 2006, women in the House of Representatives have consistently outvoted their male colleagues on environmental protection. The average LCV score of women in the House over the 13-year period was 70 compared to 43 among men. Women in the House of Representatives also outscored men in the House every year over the 13-year period studied.

Representative Doris Matsui (D-CA) helped secure over $300 million in American Recovery & Reinvestment Act funds for energy efficiency programs, research and development and job training, including $127.5 million for smart grid deployment.


Representative Elise Stefanik (R-NY) joined the House Climate Solutions Caucus in 2017 to develop policies addressing climate change. She also helped defeat an amendment to a Defense Department authorization bill that would have blocked a study on the impact that climate change is having on national security.

Representative Nydia Velázquez  (D-NY) has led efforts to ensure communities are more resilient to future weather catastrophes including $511 million in federal resources for flood and storm resiliency projects.

Women with Perfect Environmental Scores in the House in 2018

Seventy percent of the representatives earning perfect LCV scores (100) in the House in 2018 were women: Yvette Clarke (NY), Lois Frankel (FL), Brenda Jones (MI), Barbara Lee (CA), Grace Meng (NY), Nancy Pelosi (CA), Lucille Roybal-Allard (CA), Mary Scanlon (PA), Jan Schakowsky (IL), Nydia Velázquez (NY), Debbie Wasserman Schultz (FL), and Susan Wild (PA).

Women’s Environmental Voting Records in the Senate


The average LCV score of women Senators from 2006-2018 was 71 compared to 46 from their male counterparts. Women Senators also outscored men in the Senate every year over the 13-year period studied.

The Energy Policy Modernization Act of 2016 marked the first time the Senate passed a comprehensive energy bill since the Bush Administration. It was led by two women from across the aisle: Senators Lisa Murkowski (R-AK) and Maria Cantwell (D-WA).

Senator Maggie Hassan introduced the Energy Storage Tax Incentive and Deployment Act of 2019 to establish an investment tax credit for business and home use of clean energy storage.

Senator Susan Collins (R-ME) and Former Senator Olympia Snowe‘s (R-ME) matching lifetime scores of 63 and 65 put them near the 13-year average for all women senators. Both women voted for public land protections, water conservation, clean energy and climate change funding, and more.

Women with Perfect Environmental Scores in the Senate in 2018

While women comprised only 23 percent of the Senate in 2018, they made up 50 percent of the LCV scores of 100, with perfect votes from Tammy Baldwin (WI), Maria Cantwell (WA), Catherine Cortez Masto (NV), Kirsten Gillibrand (NY), Kamala Harris (CA), Margaret Hassan (NH), Mazie Hirono (HI), Amy Klobuchar (MN), Patty Murray (WA), Tina Smith (MN), Debbie Stabenow (MI), and Elizabeth Warren (MA).

“We’ve got to get more women to run. We need to be strategic and identify women to run in open seats at every level of leadership. And once those women are recruited, we need to make sure that they have the support, financial and otherwise, to be successful.”

Debbie Walsh, Director, Center for American Women and Politics
