Polls show that Pennsylvanians are concerned about a range of environmental issues, from clean water and wildlife conservation to global warming and renewable energy.
Relatively few public opinion surveys explore the environmental views of Pennsylvanians. Those that do show that most Pennsylvanians care about protecting the Commonwealth’s water, land, wildlife, and air. Majorities believe the government should limit pollution, protect public parks and forests, and lead the shift from fossil fuels to renewable energy sources.
This guide highlights the findings of recent polls pertaining to regulation, the function of government agencies, and climate change and energy issues. A companion guide, How Pennsylvanians View Government Funding of Conservation: An Overview of Polling and Voting Results, examines how the public views government investments in conservation.
Anglers and hunters, who are more likely to have conservative political views and/or identify as Republicans, express support for conservation. A 2015 poll  regarding the federal Clean Water Act found that 81% of registered Pennsylvania voters who identify as hunters and/or anglers support applying the Act to smaller headwater streams and wetlands, with nearly six in 10 (59%) indicating strong support. A large majority of Republicans (73%), independents (83%), and Democrats (95%) are all in favor.
This support makes sense considering that 85% of Pennsylvania voters who hunt or fish believe that protecting water quality and habitat is compatible with a strong economy, and that 78% view this application of the Clean Water Act as an “important safeguard” rather than a “burdensome regulation.”
A 2014 poll  found that Pennsylvanians view habitat loss and urban sprawl as the biggest threats to nongame wildlife in the state. A vast majority of respondents (92%) also believe that conserving threatened and endangered species is an important function of the Pennsylvania Game Commission and Fish and Boat Commission; 75% believe this is a “very” important function.
Data from the Yale Program on Climate Change Communication  shows that most Pennsylvania voters are concerned about global warming and its impact: 69% believe global warming is happening, and more than half (58%) report being “worried” about it. Philadelphia County has the highest percentage of worried voters (72%), while Bedford and Jefferson counties have the lowest (46%). Nearly seven in 10 voters statewide believe that global warming will harm future generations (69%) as well as plants and animals (68%).
Strong majorities of Pennsylvania voters think the government should combat global warming by reducing the pollution that causes it. Eighty-two percent support funding research into renewable energy sources, and 65% support laws requiring utilities to produce 20% electricity from renewable sources. Furthermore, 76% support regulating carbon dioxide as a pollutant, and 69% support strict carbon dioxide limits on existing coal-fired power plants.
A 2015 poll  found that 82% of Pennsylvania voters support the development of a state plan to reduce carbon pollution and increase clean energy and energy efficiency, including 30% who express “strong” support. Democrats (89%), Republicans (77%), and independents (73%) all agree on this state-level approach. If the governor implemented such a plan, only 7% would view them less favorably.
The same 2015 poll found that more than six in 10 Pennsylvania voters (61%) say that increased renewable energy will create jobs, compared to only 16% who think it will cost jobs. More voters (47%) believe clean energy will reduce energy costs than increase costs (33%). Nearly all voters (97%) support increases in energy efficiency, including 77% expressing “strong” support. Voters also overwhelmingly support solar (91%), wind (85%), and hydropower (84%). Relatively fewer voters (69%) support coal as an energy source, and relatively more (29%) oppose it.
Pennsylvania offers many opportunities for its residents to experience the outdoors. There are 121 state parks, comprised of more than 200,000 acres, as well as two million acres of state forest. Among Pennsylvanians, there is solid support for protecting these lands. A 2014 poll  found that 57% of Pennsylvania voters oppose natural gas extraction under state parks and forests, compared to 36% in favor. Responses broke along political lines to a greater degree than other conservation-related polls, with 71% of Democrats, 58% of independents, and 38% of Republicans in opposition.
