In 2022, women hold a record 145 seats in Congress. Despite major gains in the past decade, women are still significantly underrepresented in federal policymaking. By some estimates, it could take a 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 27 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.
Research in the European Journal of Political Economy 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 and a 2019 study in the Review of Policy Research both found that women in Western parliaments were more likely to support environmental legislation than men.
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 and looks further into the past. After comparing annual LCV scores each year from 1972-2021, 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.

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 1972-2021 is 69.3 while men’s is 45.6.
Within each political party, this pattern persists, although the discrepancy is less pronounced. The average scores of Democratic women surpass those of Democratic men in nearly every year since 1972 and their average is much higher: 87.7 vs 70.1. Since 2003, the scores of Republican women in the House have roughly tracked Republican men’s scores, but their overall average since 1972 is 24 compared to men’s 19.5.

Women’s Environmental Voting Records in the Senate
Just as in the House of Representatives, women’s average LCV score in the Senate since 1972 is higher than men’s overall (67.8 vs 45.5) and within each party (D: 85.7 vs 70.1; R: 30.3 vs 19.8). Year by year, the picture is more complicated, primarily because comparatively few women 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.

Big surprise: Big oil isn’t walking the walk when it comes to tackling climate change. But fossil fuel giants have awarded bonuses to top execs based on supposedly making progress toward climate goals. I’ve called for an SEC investigation. https://t.co/37BLxYEQKv

It’s no coincidence that our most toxic industries are often next door to low-income communities.

While those industries get rich, these communities are suffering from higher rates of asthma, cancer and COVID.
I intro'd the Environmental Justice For All Act to help change that. pic.twitter.com/z23BM1X7Ds
“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.”
