Carbon leakage is a term used to describe the increase in the global level of greenhouse gas emissions when businesses, particularly those in energy-intensive industries, relocate from countries with strict environmental policies to those with weaker or no such policies. This movement results in an unintended consequence where global emissions remain unchanged or even increase, countering the intended environmental benefits of stringent regulations.
Historical Context
The concept of carbon leakage emerged with the global push towards reducing greenhouse gas emissions in the late 20th century. It gained prominence during international climate negotiations such as the Kyoto Protocol (1997) and the Paris Agreement (2015), where differential commitments of countries led to concerns about competitiveness and relocation of industries.
Types/Categories of Carbon Leakage
- Short-Term Leakage: Immediate relocation of production activities to jurisdictions with lenient environmental regulations.
- Long-Term Leakage: Gradual shift in investment patterns and the establishment of new facilities in regions with less stringent environmental policies.
- Carbon Abatement Investment Leakage: Investment in low-carbon technologies and innovations in countries with less rigorous regulations due to lower costs.
Key Events
- Kyoto Protocol (1997): Highlighted initial concerns about carbon leakage as developed nations committed to stringent emission reduction targets.
- European Union Emission Trading Scheme (EU ETS) (2005): Implementation led to studies assessing the risk of carbon leakage for European industries.
- Paris Agreement (2015): Strengthened global focus on uniformity in emissions reduction commitments to mitigate carbon leakage.
Detailed Explanations
Mechanisms of Carbon Leakage
- Direct Leakage: Occurs when industries physically relocate production facilities.
- Indirect Leakage: Happens through changes in global market dynamics, such as changes in the price of fossil fuels, leading to increased consumption elsewhere.
Economic Models
Multi-Region Input-Output (MRIO) Models
MRIO models are used to trace emissions through supply chains across multiple regions, highlighting potential shifts in production and emissions.

Importance
Understanding and mitigating carbon leakage is crucial for global environmental policy as it ensures the effectiveness of national efforts in reducing emissions. It highlights the need for international cooperation and uniform policies to combat climate change effectively.
Applicability and Examples
Case Study: European Union
The EU ETS has faced concerns over carbon leakage, particularly in sectors like steel, cement, and aluminum. Measures such as free allocation of permits to at-risk industries and border carbon adjustments have been implemented to mitigate these risks.
Global Impact
Policies like the Carbon Border Adjustment Mechanism (CBAM) are being considered globally to address carbon leakage by leveling the playing field for domestic industries.
Considerations
- Policy Uniformity: Coordinated international efforts are essential to reduce disparities in environmental regulations.
- Innovation Incentives: Encouraging investment in low-carbon technologies globally can mitigate carbon leakage.
- Economic Competitiveness: Balancing stringent environmental policies with economic competitiveness is crucial to prevent industry relocations.
Related Terms with Definitions
- Carbon Border Adjustment Mechanism (CBAM): A policy tool to impose tariffs on imported goods based on their carbon content.
- Emission Trading Scheme (ETS): A market-based approach to controlling pollution by providing economic incentives for reducing emissions.
- Greenhouse Gas (GHG): Gases that trap heat in the atmosphere, contributing to global warming.
Comparisons
- Carbon Leakage vs. Carbon Offsetting: While carbon leakage refers to the unintended increase in emissions due to policy disparities, carbon offsetting involves compensating for emissions by investing in environmental projects.
Interesting Facts
- Studies suggest that the risk of carbon leakage varies significantly across sectors, with energy-intensive industries being more vulnerable.
- Carbon leakage can undermine the efficacy of regional climate policies and exacerbate global inequality in environmental impacts.
Inspirational Stories
- The EU’s proactive measures in combating carbon leakage through innovations in policy have inspired other regions to adopt similar mechanisms.
