In 2026, women hold 150 seats in Congress. Despite major gains in the past decade, women are still significantly underrepresented in federal policymaking. By some estimates, it could take over a century at the 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 28 percent of Congress. Women of color currently hold 10 percent of seats in Congress despite comprising roughly 20 percent of the country’s population.
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.
Research in the European Journal of Political Economy (2019) found that female representation in national legislatures leads countries to adopt more stringent climate change policies. 91 countries were included in the study.
Similarly, a 2019 study in the Journal of Environmental Politics, a 2019 study in the Review of Policy Research, a 2022 study in the European Journal of Political Research, and a 2025 study in Kybernetes found that women’s political representation correlates with better environmental policies and outcomes.
In previous iterations of our report When Women Lead (in 2003 and 2011), we analyzed the voting records of federal legislators going back to 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, looks further into the past, and includes demographic breakdowns by race and ethnicity. After comparing annual LCV scores each year from 1972-2025, we found that women legislators—especially women of color legislators—vote for environmental protections more often than their male counterparts in both the House and Senate.
Climate change, pollution, food and energy justice, 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—especially women of color—to public office, and support them during their tenure.
Women’s Environmental Voting Records in the House of Representatives
In the US House of Representatives, women have had higher average environmental scores in every year that LCV has kept records. Women’s average annual score from 1972-2025 is 70 while men’s is 45.
Women of color have the highest combined average annual LCV score in the House in 2025 at 91 (see race and ethnicity breakdown here).
Within each political party, the gender discrepancy persists, although it’s less pronounced and shrinking in recent years. The average scores of Democratic women surpass those of Democratic men in nearly every year since 1972 and their average is much higher: 89 vs 71. Since 2003, the scores of Republican women in the House have roughly tracked Republican men’s scores, but their overall average since 1972 is 21 compared to men’s 18.

I was honored to join Cuyahoga County Executive Chris Ronayne, Cleveland Mayor Justin Bibb, and Cleveland Metroparks to break ground on the Euclid Beach Connector trail – supported with $850,000 secured by my office. This trail will expand Lake access – another win for NE Ohio!

“Environmentally minded voters, activists and interest groups should seriously consider the way their representatives’ gender may impact environmentalism and take seriously the role of gender equality in their governments.”
Women’s Environmental Voting Records in the Senate
Just as in the House of Representatives, women’s annual average LCV score in the Senate since 1972 is higher than men’s overall (67 vs 45) and within each party (D: 88 vs 72; R: 26 vs 19).
Year by year, the picture is more complicated, primarily because comparatively few women—and even less women of color—have served in the Senate. From 1973-1977, no women served at all, and until 1991, only 1 or 2 women served at any one time. To put it another way, pre-1991 averages account for the scores of 98-99 men vs 1 or 2 women. The large swings in LCV scores in earlier years are partly due to this small sample size. Meanwhile, only eight women of color have served in the Senate in its entire history. In 2025, women of color have the highest combined average annual LCV score of any group in the Senate at 98.
We owe our future generations breathable air, drinkable water, and a livable planet on which to live. Giving corporations a blank check to poison our water is just wrong.

It's hard not to be in awe of our beautiful planet after seeing the photos taken by Artemis II on their recent mission. Today, on Earth Day, as this regime attacks environmental protections, let these photos be a reminder of the importance of protecting our only home — Earth.

“[US] states under the leadership of female governors experience lower levels of CO2 emissions than those with male governors, indicating female leadership’s potential to promote environmental sustainability.”
Solutions
We can close the gender gap and make a difference for the environment by following these suggestions from fellow advocates:

Methodology
When Women Lead uses the following datasets:
1. The League of Conservation Voters (LCV) Scorecard, which compiles federal legislator votes on bills including clean air and water, energy, climate change, environmental justice, public health, public lands and wildlife conservation, democracy, worker protection, and spending for environmental programs (methodology here).
2. The Center for American Women & Politics (CAWP) tally of Women Officeholders by Race and Ethnicity (methodology here).
3. the @unitedstates project, a shared commons of data and tools for the United States.
