A recent study has revealed that multinational companies often establish their more polluting operations in countries with less stringent environmental regulations. This phenomenon, which may lead to what is termed “carbon leakage,” is when businesses shift emissions to nations with more relaxed policies, despite being headquartered in countries with strict environmental laws.
The research, conducted by scholars including Itzhak Ben-David, a finance professor at The Ohio State University, utilized a unique dataset provided by CDP, a non-profit organization. This data spanned from 2008 to 2015, detailing the carbon dioxide emissions of 1,970 public firms across 218 countries. The study, published in the journal Economic Policy, aimed to directly observe the influence of environmental policies on firms’ carbon emissions at a global level.
Using the World Economic Forum’s ratings on environmental policy strength, the study found that while stringent regulations do reduce a country’s emissions, they can also result in increased emissions in other countries. For instance, improving environmental policy scores akin to Germany’s standards is linked to a significant decrease in global emissions, yet it may also coincide with a rise in emissions abroad.
The investigation also looked into the dynamics of whether strict regulations in a company’s home country “push” pollution activities abroad or if lenient policies in other countries “pull” them in. The evidence pointed more towards a “push” effect.
The study highlighted industries with high pollution levels as the most likely to move their operations in response to strict home country regulations. It also noted a declining trend of emissions within a company’s home country, coupled with an increase in the number of countries where a firm operates and emits carbon dioxide.
The authors of the study call for international collaboration in environmental policy to maximize the effectiveness of emissions reduction efforts on a global scale.
