Political polarization has emerged as a significant barrier to effective climate action, with new research suggesting that heightened partisan hostility correlates with increased carbon dioxide (CO2) emissions from power plants.A recent study conducted by researchers at the University of Colorado Boulder highlights how deepening political divides can hinder democracies' ability to manage climate change effectively.

colorado.eduThe study, published in the American Sociological Review, examined 20,115 fossil-fueled power plants across 92 democratic countries.It specifically focused on levels of "affective polarization," which refers to the intense animosity and distrust between opposing political parties.The findings indicate that as affective polarization rises, democracies struggle to enforce climate regulations, leading to significantly higher CO2 emissions from power plants.

colorado.eduGrant, the study's senior author, notes that in countries with high levels of affective polarization, such as Poland, CO2 emissions were nearly 8% above average.In contrast, Uruguay, with lower polarization, had emissions 11% below average.

colorado.eduThis pattern is particularly concerning given the increasing urgency of climate change.The US ranks high on the affective polarization scale and exhibits above-average emissions, reflecting a broader trend where political division hampers progress on climate goals.

csis.orgAchieving these ambitious climate goals will require unprecedented investments and significant changes across all sectors of the economy.Transitioning to renewable energy sources and enhancing energy efficiency are essential steps toward reducing emissions.
