Multinational firms headquartered in countries with strict environmental policies often choose to conduct their most polluting activities in foreign countries with weaker policies. This is known as carbon leakage and is driven by tightened environmental policies in home countries that incentivize firms to pollute abroad. While firms based in countries with strict policies are more likely to export pollution abroad, they nevertheless produce fewer overall carbon emissions globally. This is because firms with good governance structures produce fewer emissions at home and export less pollution to foreign countries. However, this also creates incentives for firms to export their pollution abroad, and without a coordinated global effort, large multinationals will continue to circumvent strict environmental regulations.

What You'll Learn
Multinational firms headquartered in countries with strict environmental policies
Multinational companies headquartered in countries with tough environmental policies tend to locate their polluting factories in countries with more lax regulations. This phenomenon is known as "carbon leakage". While firms in countries with stringent environmental regulations emit less carbon dioxide overall, they are also more likely to export pollution to foreign countries with less strict environmental policies.
A study by Itzhak Ben-David of The Ohio State University's Fisher College of Business found that an increase in the environmental policy score from China (2.1) to Germany (5.5), suggesting stronger regulations, resulted in 44% lower global emissions. However, it also led to a 299% increase in foreign emissions compared to the companies' home countries. This demonstrates that while stricter environmental policies in one country can reduce global emissions, they can also push pollution to other nations with less stringent regulations.
The same study examined whether stricter policies "pushed" firms to pollute elsewhere or if lax regulations "pulled" firms to countries where it was easier to pollute. The results indicated that the environmental policies in the home country had a more significant influence on the firms' decisions. This suggests that it is the "'push' effect of strict domestic policies that drives firms to relocate their polluting activities rather than the "pull" effect of lenient foreign policies.
Firm-level governance also plays a role in this dynamic. Well-governed firms with strong governance structures are found to produce fewer emissions domestically and export fewer emissions to foreign countries when the home country has strict environmental policies. Good governance mechanisms may encourage managers to consider long-term value and push the firm towards production with lower emissions. On the other hand, firms with weak governance structures are more likely to export their polluting activities abroad to maximize profits and avoid the costs of complying with strict domestic regulations.
While individual countries' strict environmental policies can help reduce global CO2 emissions to a certain extent, they are not enough to curb the most damaging effects of climate change. Countries need to collaborate and take coordinated action to address this issue effectively and prevent multinational firms from circumventing regulations by exporting their pollution abroad.

Foreign countries with relatively weaker policies
Multinational firms headquartered in countries with strict environmental policies choose to conduct their polluting activities in foreign countries with relatively weaker policies. This is known as "carbon leakage", where firms from highly regulated home countries locate their CO2-intensive activities in countries with less stringent environmental regulations. This strategy is driven by tightened environmental policies in home countries that incentivize firms to seek more economical production methods abroad.
For example, highly polluting substances, such as cancer-causing benzene, are mixed into fuels before being exported to Africa. In most developed countries, the level of sulfur in diesel is around 10-15 parts per million. However, in ports like Amsterdam, Antwerp, and Rotterdam, diesel fuels are mixed to have sulfur content as high as 10,000 parts per million for export to African countries, where standards are lacking or outdated. Additionally, African countries often import used cars from Japan and Europe, including older vehicles that may no longer meet stringent environmental standards in their countries of origin.
Another example is the textile industry's impact on countries like Bangladesh. For every ton of finished jute yarn, 2.1 tons of CO2 are emitted locally into the atmosphere. Similarly, in Kenya, the processing of palm oil for export results in 1.8 tons of pollutants equivalent to dichlorobenzene for every ton produced, straining local soils.
Firms in pollution-intensive industries and those with poor corporate governance are more likely to export pollution to countries with weaker environmental policies. However, it is important to note that tightening environmental policies in home countries can push these firms to reduce their overall carbon emissions globally, even if they continue to export pollution.

Carbon leakage
The issue of carbon leakage is complex and multifaceted. It arises due to the interplay between international trade, climate policies, and the varying stringency of emissions regulations across countries. To address carbon leakage, various measures have been proposed, such as implementing a Carbon Border Adjustment Mechanism (CBAM) and providing free emission allowances to industries at risk of leakage. However, there is conflicting evidence regarding the effectiveness of these policies, and the term "carbon leakage" itself encompasses two related but distinct concepts, adding to the complexity of the issue.
The European Union, through the EU Emissions Trading System (EU ETS), recognizes the risk of carbon leakage in certain energy-intensive industries. To maintain the competitiveness of these industries, the EU provides free allowances to sectors deemed to be at significant risk of carbon leakage. These allowances are based on benchmarks and are intended to support industries in transitioning to more sustainable practices without incurring excessive costs.
Preventing carbon leakage requires global coordination and collaboration. While some countries may successfully reduce their emissions, the overall goal of mitigating climate change cannot be achieved if other countries experience a corresponding increase in emissions. It is essential to strike a balance between environmental protection and the economic competitiveness of industries to ensure a sustainable future for all.
Additionally, it is worth noting that carbon leakage is not solely driven by climate policy differences. The offshoring of emissions can also occur due to broader determinants of international trade and investment. Rich countries, for example, may consume goods produced in other countries, effectively offshoring their emissions. This highlights the importance of considering consumption-related emissions and the global supply chain in the fight against climate change.

Damage to freshwater or marine ecosystems
Multinational firms often choose to conduct their polluting activities in countries with weaker environmental policies. This strategy, known as "carbon leakage", allows them to avoid the costs associated with complying with stringent environmental regulations in their home countries. As a result, countries with lax environmental regulations become dumping grounds for pollution, suffering the consequences of degraded ecosystems and natural resources.
Freshwater and marine ecosystems are particularly vulnerable to the impacts of pollution. The majority of pollutants that enter the ocean, for instance, originate from human activities along coastlines and far inland. Nonpoint source pollution, such as runoff from farms, septic tanks, vehicles, and livestock ranches, is a significant contributor to ocean pollution. Point source pollution, such as oil or chemical spills, and discharge from faulty factories or water treatment systems, while less frequent, can have devastating impacts on aquatic ecosystems.
One of the most pressing issues in marine pollution is plastic waste. Plastic debris, including derelict fishing gear, poses a significant threat to marine life. Animals can become entangled in plastic debris, and smaller organisms may ingest microplastics, absorbing toxic chemicals into their tissues. These toxins then migrate up the food chain, eventually reaching humans. Plastic waste is long-lasting, with some items taking hundreds of years to decompose. As a result, plastic pollution has led to the formation of massive garbage patches in the ocean, such as the Pacific Garbage Patch, which spans approximately 1.6 million square kilometers between California and Hawaii.
Nutrient pollution, caused by the excessive use of fertilizers on farms, is another significant concern. The runoff of chemicals, such as nitrogen and phosphorus, into waterways that eventually flow into the ocean, promotes the growth of harmful algal blooms, or "red tides." These algal blooms can produce toxic effects, affecting marine life and sometimes even humans. When large amounts of algae sink and decompose, they deplete the oxygen supply available to healthy marine life, leading to the creation of dead zones.
Pollution also directly harms marine life, such as algae, jellyfish, sea cucumbers, fish, whales, seals, and stingrays, disrupting the delicate balance of aquatic ecosystems. Contaminants like heavy metals, oil spills, and pesticides can cause deformities and reproductive issues in fish and other aquatic organisms, even leading to death. Additionally, certain contaminants promote the growth of fungus, bacteria, and algae, which can overtake and impede the growth of naturally occurring plants that marine life depends on for survival.
To protect freshwater and marine ecosystems, collective action and global coordination of regulations on carbon dioxide emissions are necessary. Individual efforts, such as reducing plastic waste and proper waste management, are also crucial in mitigating the impacts of pollution on these fragile ecosystems.

Dirty fuels and vehicles in Africa
Multinational firms often release their carbon emissions in countries with weaker environmental policies. This phenomenon is known as carbon leakage. While strict environmental policies in a company's home country can help reduce overall CO2 emissions, they also create an incentive for firms to export their pollution abroad.
Africa is one of the regions that has suffered from the export of dirty fuels and old vehicles from western countries, particularly Europe. These dirty fuels and vehicles emit up to 100 times more small particulates, which can enter the bloodstream through the lungs and cause damage to the whole body, including the brain. Public Eye, an NGO, exposed how European trading companies were exploiting weak regulatory standards in West African countries, allowing for the export of fuels with sulfur levels up to 300 times higher than permitted in Europe.
In response, five West African countries—Nigeria, Benin, Togo, Ghana, and Cote d'Ivoire—have agreed to ban the import of dirty fuels from Europe and introduce strict standards for cleaner, low-sulfur diesel fuels and vehicle emissions. The Partnership for Clean Fuels and Vehicles (PCFV), a global public-private partnership hosted by UN Environment, has been instrumental in supporting countries in developing policies and standards to eliminate high-sulfur fuels and transition to cleaner alternatives.
While progress is being made, with 23 developing countries adopting low-sulfur diesel standards, the majority of countries still lack the necessary standards to prevent the dumping of dirty fuels and vehicles. It is essential for both the importer and exporter to take responsibility and work together to protect the health of citizens and the environment.

Frequently asked questions
Multinational firms headquartered in countries with strict environmental policies often choose to conduct their polluting activities in foreign countries with relatively weaker policies. This is known as "carbon leakage".
The consequences of exporting pollution can be detrimental to the environment and human health in the receiving country. For example, in Kenya, for every ton of palm oil processed for export, 1.8 tons of pollutants equivalent to dichlorobenzene are left in the environment, straining local soils.
Carbon leakage is driven by a combination of push and pull factors. The “push” factor is when firms export their polluting operations to foreign countries in response to tightened environmental regulations in their home countries. The "pull" factor is when firms are attracted to countries with lenient environmental policies and low enforcement.
Addressing exported pollution requires a coordinated global effort to combat climate change. Policy-makers should focus on curbing the ability of pollution-intensive industries to export pollution to countries with lax environmental regulations. Regional trade agreements can also help manage pollution caused by international trade by spreading responsibilities between buyers and sellers.
