# Was Partisanship Good for the Environmental Movement?

*This is the third in a sequence of posts taken from my recent report:* [*Why Did Environmentalism Become Partisan?*](http://aiimpacts.org/wp-content/uploads/2023/04/Why-Did-Environmentalism-Become-Partisan-1.pdf)

Summary
-------

Rising partisanship did not make environmentalism more popular or politically effective. Instead, it saw flat or falling overall public opinion, fewer major legislative achievements, and fluctuating executive actions.

Public Opinion
--------------

One hypothesis is that partisanship was useful, or even necessary, for an issue to become popular. Maybe journalists never would have covered the story if it did not involve an exciting partisan contest. The public then might have never realized that this is a thing they could care about.

The polling data do not support this hypothesis.

The clearest data from McCright et al.[^oc14yb262p] Over 70% of both parties, and both ideologies, supported more government spending on the environment in 1990. Then, over the next 20 years, Republicans’ support for environmental spending fell dramatically while Democrat support remained roughly constant. These polls show declining overall support as partisanship increased.

The Gallup data is more ambiguous.[^hyfh842aec] It starts later, so it cannot show what was happening in the 1990s. For four different questions about global warming, Gallup shows roughly flat support from 2001-2021, although there have been fluctuations in the level of support.

Public opinion is not quite the same thing as public attention. Maybe partisanship increases how much people are talking about an issue, even if it has little impact on the support as measured in polls. As a proxy for public attention, I will use Google Book’s Ngram, which shows how frequently phrases appear in a corpus of English language books published each year.

For many environmental issues, there was a peak in the early 1990s. Public attention was growing prior to the issue becoming partisan and declining once the issue had become partisan. This might be because the environmental movement itself shifted focus away from these issues. ‘Pollution’ shows a similar peak around 1990, but also a larger peak in the early 1970s. ‘Climate change’ shows a somewhat different pattern: rapid growth before 1990, which then levels off until the mid-2000s, followed by resumed growth. It is possible to have increasing public attention while a topic is highly partisan, but for all of these environmental issues, public attention was flat or falling while partisanship was becoming established in the 1990s and early 2000s. Increasing partisanship does not seem to be a reliable way to attract public attention.

Republicans’ opposition to climate change does not seem to be a result of a lack of information. Two polls in swing states in 2011 indicated that Republicans and Democrats with less education, or who said they know little about climate change, have similar views. As education and knowledge increase, Democrats became more concerned about climate change, while Republicans became less concerned.[^iwcfcx6k1hm] This result is consistent with the overall trends: as time goes on, and people become more familiar with climate change, it exacerbates the partisan divide without increasing overall support.

Legislation
-----------

Many of the goals of environmentalism cannot be directly achieved by public opinion: they require new legislation.

To determine if partisanship has made it easier or harder to pass legislation, I investigated when pieces of major environmental legislation have been passed.

What counts as ‘major’ environmental legislation? 

The Congressional Research Service produced a summary of the “major statutes administered by the EPA” in 2013[^7kz3bh8jxdr] and the Library of Congress has a research guide about “significant legislation governing environmental law and policy.”[^bilb26nj4f6] Any law mentioned in either of these is included.[^w6qfnedmcj8] I categorize these laws as dealing with environmental impact statements, air pollution, water pollution, solid waste, toxic substances, or endangered species. All of these are domestic laws – treaties will be discussed below.

These laws often create the framework of U.S. environmental policy. Newer legislation might not need to create a new framework, and instead could be an amendment to the existing framework. In addition, some of these laws superseded earlier environmental legislation. To account for both of these possibilities, I turned to Wikipedia. The sidebar of the Wikipedia article for each of these laws has a list of “major amendments.” I include each of these as a piece of major environmental legislation, checking to make sure there is no double counting.[^5w7w6ejm20r] I also read the History section to check for any major precursors. Each law has a well-developed article. I trust their judgment for what counts as a “major amendment” and what precursors should be mentioned more than a search and categorization I might do specifically for this report.

A graph of the number of pieces of major environmental legislation and amendments since 1945 is shown in Figure 4, binned into 4 year intervals corresponding to presidential terms.

There was clearly more environmental legislation passed in the 1960s-80s than in earlier or later decades. The modern environmental movement began in the 1960s and became legislatively successful within the decade. The environmental movement became partisan in the 1990s, and stopped being as capable of passing major legislation. 

Treaties show a similar, if sparser, pattern. During the 1970s and 1980s, the Senate ratified four international environmental treaties unanimously.[^o0deen4chpi] The U.N. Framework Convention on Climate Change was also ratified using a division vote in 1992.[^o90kk9hn8cd] Between 1989 and 2001, the United States signed four environmental treaties which the Senate refused to ratify, including the Kyoto Protocol.[^2t6lmwiyhps] More recently, international environmental agreements have been structured so they do not require ratification from the Senate – like the Paris Climate Accords.[^je9h422dxp]

Increasing partisanship has made it more difficult for the environmental movement to pass its legislative agenda.

Executive Actions
-----------------

Environmental policy can also be enacted by the executive branch. When environmentalism is partisan, executive action fluctuates with broader political winds.[^kajs64o4r7] Over the medium-to-long term, it is unlikely that one political party will consistently win elections. Having bipartisan support for an issue results in more stable and reliable executive policies.[^l4ga9wf6jna]

This can be most clearly seen in international agreements. The Clinton administration negotiated the Kyoto Protocol, the Bush administration declared that they would not implement it, the Obama administration negotiated the Paris Accords, the Trump administration withdrew from them, and the Biden administration rejoined them.[^w13o6gcujql]

Much of the implementation of environmental policy occurs in the executive branch, especially the EPA. While Republican administrations have not been effective at reducing the size or budget of the EPA,[^jbx7jij7gr] they have chosen leaders who have closer ties to fossil fuel companies than to the environmental movement. Many of the details of how to enact policy are small enough to not be widely reported, but some are. Examples include changing rules for air pollution[^o6imlcqv0oj] or removing ‘climate change’ from the EPA’s website.[^snmfnk7nka] These changes can be reversed by future Democratic administrations, but the result is that environmental protections are not consistently applied.

Conclusion
----------

Environmentalism was a very successful movement from the 1960s-1980s. It convinced a majority of people in both parties of the importance of its concerns. It was effective at passing domestic legislation and negotiating international treaties. Presidents from both parties supported the movement.

The rise in partisanship starting in the 1990s was bad for environmentalism. Some presidential administrations are now hostile to the movement. Major legislation is still sometimes passed, but much less frequently than before. Overall public support did not increase as environmentalism became partisan.

The result of the vote is not recorded other than whether it passed. Treaties require 2/3 support of the Senate to be ratified, so it had to have had significant bipartisan support. Typically, division votes and voice votes are used when the result of the vote is not in doubt beforehand.About Voting. U.S. Senate.
