Researchers say eco-friendly democracies are likely just outsourcing their pollution

(CN) — Democratic nations often pride themselves on being environmentally responsible, but reality may be more complex and less flattering: while these countries may report lower pollution levels domestically, they’re often exporting their environmental impact to other nations.

Researchers say the toll of pollution offshoring on the planet is significant — and ironic, given the “green” image many democracies promote.

The authors of the study published Wednesday in the open-access journal PLOS Climate describe this dynamic as “externalizing the environmental costs of economic activity,” made possible through global trade, which transfers the “environmental burden” to exporting states.

A recent UN report highlights how democracies such as Germany and Japan frequently shift the production or consumption of pollution-intensive goods to countries like China.

As a result, while democracies maintain cleaner environments at home, the environmental burden is borne elsewhere.

“We provided one of the first systematic studies on how much pollution offshoring is associated with domestic emission levels in democracies,” the authors noted in a statement. “The main result is that pollution offshoring is linked significantly and substantively with lower greenhouse gas emissions ‘at home’ in democracies.”

The study builds on earlier research suggesting that democracies generally have better environmental records than authoritarian regimes. To test this, researchers Thomas Bernauer and Ella Henninger of ETH Zurich and Tobias Böhmelt of the University of Essex analyzed data from 161 countries between 1990 and 2015.

They examined a wide range of variables, including multi-regional trade data and greenhouse gas emissions like carbon dioxide and methane. Their goal was to determine whether democratic countries offshore more pollution and if that affects their domestic emissions levels.

They found that democracies are indeed more likely to outsource pollution-intensive activities.

“The association between democracy and pollution offshoring is positive and statistically significant,” the researchers say.

As a result, democratic countries record significantly lower emissions domestically — more than one metric ton per capita less than less democratic countries — while contributing to higher emissions abroad.

The researchers suggest that this pattern may arise because democracies tend to support free trade, value scientific input, and implement stricter environmental regulations at home. These factors encourage policymakers to maintain domestic air and water quality, even if it means outsourcing emissions elsewhere.

The authors say the research questions the moral high ground that democratic nations often claim when it comes to environmental protection.

They argue that high-income democracies, in particular, should reexamine their policies with a broader, global perspective — one that accounts for the full environmental cost of their consumption habits.

Future research will explore the role of geography in pollution offshoring and attempt to identify which specific pollutants are most commonly exported by democratic economies.
