As global leaders gathered in Brazil for COP30 to discuss measures to limit climate change, expert suggestions are emerging for the engagement of community-based efforts in climate policies.
Experts emphasize that while individual efforts may seem small, joining community-based initiatives can significantly amplify impact and create meaningful change.
Leah Stokes, a professor of environmental politics and public policy at the University of California, Santa Barbara, explains that acting collectively allows people to expand their influence beyond what one person can achieve alone.
One of the most effective ways to influence climate policy in a democratic country is through voting, which allows citizens to select officials who determine system-level policies that affect environmental outcomes.
Anthony Leiserowitz, director of the Yale Program on Climate Change Communication, notes that elected officials set budgets, write laws, and make decisions that have far-reaching implications for climate action, including funding priorities and environmental regulations.
The U.S. has demonstrated the impact of elections on climate policy, withdrawing from the Paris Agreement twice after voters elected leaders who deprioritized climate action.
Even a single vote can matter, especially in close elections, influencing federal, state, and local decisions that shape public transit, energy infrastructure, and policies promoting cleaner technologies.
Engaging directly with elected officials is another important strategy, either by calling representatives or attending public meetings where policy decisions are debated and made.
Many local, state, and federal agencies hold public hearings that are under-attended, giving individuals a chance to make an outsized impact on decisions affecting energy systems, zoning, and environmental approvals.
Stokes emphasizes that local action, such as participating in hearings or permit processes for solar and renewable energy projects, can drive substantial change in communities, complementing broader national and international efforts.
Volunteering with organizations that share your values allows individuals to support campaigns, legal actions, or advocacy initiatives, thereby increasing the collective impact on climate-related issues.
Leiserowitz notes that social, political, and economic systems often shift not simply because of rational arguments but because constituents demand change, and volunteering helps build that constituency.
Even large-scale ambitions, such as expanding high-speed rail or transitioning to cleaner energy, become more feasible when individuals contribute to organized efforts, signaling to others that engagement is worthwhile and inspiring further participation.
Research indicates that seeing others take action provides hope and motivation, reinforcing the effectiveness of community involvement in driving climate solutions and creating lasting change at multiple levels of society.
By combining voting, direct engagement, local initiatives, and volunteerism, individuals can collectively influence climate policies and contribute to tangible improvements in sustainability, demonstrating that personal action, when multiplied across communities, can be highly consequential.
