15.1 Trends in Public Environmental Attitudes and Behaviors

Public opinion on environmental issues has fluctuated over time, with peaks often coinciding with major events. Long-term trends show increased concern since the 1960s, but partisan polarization has grown in recent decades, with Democrats generally expressing higher concern.

Various factors influence environmental attitudes, including demographics, personal values, and social norms. Public opinion can shape policy by creating political pressure, but there's often a gap between stated attitudes and actual behaviors, highlighting the need for targeted interventions.

1 of 3

• Public opinion on environmental issues has fluctuated over the past several decades
• Periods of heightened concern often coincide with major environmental events or crises
  • Publication of Silent Spring (1962) raised awareness of pesticide impacts on wildlife
  • Cuyahoga River fire (1969) highlighted the problem of industrial water pollution
  • Exxon Valdez oil spill (1989) drew attention to the risks of oil drilling and transportation

Long-term Trends in Environmental Attitudes

• Long-term trends show a general increase in environmental concern since the 1960s
  • Concern for issues like air and water pollution, climate change, and conservation has grown
• Level of concern may vary depending on the specific issue and time period
  • Climate change concern has risen sharply in recent years (2000s-2020s)
  • Conservation issues like endangered species protection saw higher concern in the 1970s-1990s

Partisan Polarization on Environmental Issues

• Partisan polarization on environmental issues has increased in recent decades
• Democrats and liberals express higher levels of concern about environmental problems
  • More likely to prioritize environmental protection over economic growth
  • Stronger support for government regulations to address environmental issues
• Republicans and conservatives express lower levels of concern and support for environmental measures
  • Tend to prioritize economic growth and development over environmental protection
  • More skeptical of government regulations and interventions in environmental policy

Tracking Changes in Environmental Opinion

• Changes in public opinion on environmental issues over time can be tracked through repeated surveys and polling
• Gallup Environmental Poll and General Social Survey ask consistent questions across multiple years or decades
  • Allows for analysis of long-term trends and shifts in environmental attitudes
• Other organizations (Pew Research Center, Yale Program on Climate Change Communication) also conduct regular surveys on environmental issues

Factors Influencing Environmental Attitudes

Demographic Factors

• Age: Younger individuals tend to express greater concern for the environment
  • Millennials and Gen Z more likely to prioritize environmental issues than older generations
• Gender: Females tend to express greater concern for the environment than males
  • Women more likely to support environmental protection measures and engage in pro-environmental behaviors
• Education level: More educated individuals tend to express greater concern for the environment
  • Higher levels of scientific knowledge and understanding of environmental issues
• Political ideology: Liberals tend to express greater concern for the environment than conservatives
  • Reflects partisan polarization on environmental issues

Personal Values and Experiences

• Personal values and beliefs can shape individuals' environmental attitudes and behaviors
  • Altruism (concern for others) and biospherism (concern for the environment) associated with greater environmental concern
  • Egoism (self-interest) associated with lower environmental concern
• Direct experiences with environmental problems can increase concern and motivation to act
  • Living in an area affected by air or water pollution
  • Experiencing the impacts of climate change (extreme weather events, sea-level rise)

Social Norms and Structural Factors

• Social norms and peer influence can shape individuals' environmental attitudes and behaviors
  • People more likely to express concern and engage in pro-environmental behaviors if they perceive these as socially desirable or common among peers
• Structural factors can facilitate or constrain individuals' ability to engage in pro-environmental behaviors
  • Availability and convenience of recycling programs, public transportation, energy-efficient products
  • Cost and accessibility of sustainable choices (organic food, electric vehicles)

Public Opinion's Impact on Policy

Shaping the Political Context

• Public opinion can influence environmental policy decisions by shaping the political context
• Policymakers more likely to prioritize environmental issues and support protection measures when they perceive strong public concern or demand for action
  • Rise of federal environmental legislation in the 1970s (Clean Air Act, Clean Water Act) followed period of heightened public concern

Support for Specific Policies

• High levels of public support for specific environmental policies can increase the likelihood of adoption and implementation
  • Renewable energy mandates (state-level Renewable Portfolio Standards)
  • Carbon pricing (cap-and-trade programs, carbon taxes)
  • Conservation measures (protected areas, endangered species protections)

Organized Opposition and Political Obstacles

• Organized public opposition to environmental policies can create political obstacles to adoption and implementation
  • Protests or lobbying efforts by industry groups (fossil fuel companies opposing climate regulations)
  • Local communities opposing land-use restrictions or renewable energy projects (NIMBY-ism)
• Opposition can hinder progress even in the face of broad public support for environmental action

Varying Influence Across Levels of Government

• Impact of public opinion on environmental policy decisions may vary depending on the level of government and specific policy arena
• Public opinion has a more direct influence on actions of elected officials at local and state level
  • Constituents' concerns and demands shape policymakers' priorities and voting behavior
• At the federal level, organized interest groups and institutional factors may play a larger role
  • Lobbying by industry groups and environmental organizations
  • Partisan dynamics and political calculations in Congress

Stated Attitudes vs Actual Behaviors

The Value-Action Gap

• The "value-action gap" refers to the discrepancy between individuals' stated environmental attitudes and their actual behaviors
• Many people express high levels of concern for the environment but fail to consistently engage in pro-environmental behaviors
  • Professing support for reducing carbon emissions but continuing to drive gas-powered vehicles
  • Expressing concern about plastic pollution but regularly using single-use plastic products

Situational and Psychological Barriers

• Situational factors can lead individuals to engage in behaviors inconsistent with their stated attitudes
  • Cost (sustainable products often more expensive)
  • Convenience (driving more convenient than public transportation in many areas)
  • Social pressure (conforming to unsustainable norms or practices)
• Psychological barriers can prevent individuals from translating attitudes into action
  • Denial or minimization of environmental problems
  • Perceived lack of control or efficacy in addressing large-scale issues
  • Optimism bias (underestimating personal environmental impact)

Narrowing the Attitude-Behavior Gap

• The attitude-behavior gap can be narrowed through interventions that address barriers to pro-environmental behavior
• Providing incentives for sustainable choices
  • Subsidies for electric vehicles or energy-efficient appliances
  • Rewards programs for recycling or using public transportation
• Increasing availability and convenience of pro-environmental options
  • Expanding recycling programs and facilities
  • Improving public transportation infrastructure and accessibility
• Using social norms and peer influence to encourage behavior change
  • Highlighting prevalence of pro-environmental behaviors in the community
  • Leveraging social networks to spread sustainable practices

Measuring Actual Environmental Behaviors

• Measuring actual environmental behaviors can provide a more accurate assessment of individuals' environmental impact than relying solely on stated attitudes
• Examples of measurable behaviors:
  • Energy consumption (electricity and gas usage)
  • Transportation choices (vehicle miles traveled, public transit use)
  • Recycling rates (percentage of waste recycled)
  • Consumer choices (purchases of sustainable products)
• Identifying target areas for behavior change interventions
  • Focusing on high-impact behaviors with large attitude-behavior gaps
  • Tailoring interventions to specific barriers and motivations for different behaviors and populations
