What is carbon tax?
Summary
The carbon tax is a tax applied to CO2 emissions, aimed at encouraging businesses and individuals to reduce their carbon footprint. Based on the "polluter pays" principle, it promotes the use of renewable energy. It also helps finance energy transition projects.

Definition of the carbon tax
The carbon tax is an environmental tax based on the polluter-pays principle, applied to CO2 emissions resulting from the combustion of fossil fuels (oil, gas, coal). Its goal is to encourage businesses and consumers to reduce their emissions by integrating the cost of carbon into products and services. Unlike the emissions trading system, where a global cap is set and emission rights are traded, the carbon tax imposes a fixed cost per ton of CO2 emitted.
Objectives of the carbon tax
The carbon tax has several key objectives in the fight against climate change:
Reduction of CO2 emissions: By imposing a cost on emissions, the carbon tax encourages businesses and individuals to lower their carbon footprint.
Incentive for the use of renewable energy: It promotes the transition to cleaner energy sources, such as solar and wind.
Energy efficiency: By increasing the cost of fossil fuels, the carbon tax encourages improvements in energy efficiency across all sectors.
Stimulation of technological innovation: It drives the development of low-carbon technologies to reduce emissions sustainably.
How the carbon tax works
The carbon tax is applied to fossil fuels (oil, gas, coal) based on the amount of carbon dioxide (CO2) emitted when they are used. It is calculated based on a price per ton of CO2 emitted, set by governments. For example, in Europe, the tax amount is determined in euros per ton of CO2. The revenue generated by this tax is collected by tax authorities and is used to fund environmental projects or support the energy transition.
The carbon tax around the world
Several countries have implemented a carbon tax, including Sweden, Canada, and France. In Sweden, the carbon tax is one of the highest in the world, at over €110 per ton of CO2, leading to a significant reduction in emissions. Canada has introduced a tax that varies by province, while France implemented a progressive tax until 2018, before suspending it due to social tensions. Results show a decrease in emissions in countries that have adopted this measure, but the economic and social impact depends on the accompanying measures implemented.
Advantages and disadvantages of the carbon tax
Advantages of the carbon tax:
- Economic efficiency: The carbon tax is an effective tool for reducing emissions by assigning a cost to CO2-related pollution.
- Revenue generation: It helps fund environmental projects such as renewable energy and green initiatives.
- Signal: The tax sends a signal to businesses and consumers, encouraging them to adopt more eco-friendly behaviors by promoting more sustainable energy choices and low-carbon technological innovations.
Disadvantages of the carbon tax:
- Impact on purchasing power: The carbon tax can increase energy costs, disproportionately affecting low-income households.
- Risk of relocation: Industries might relocate production to countries without a carbon tax, potentially leading to local job losses.
- Administrative complexity: Implementing the tax requires significant administrative management and can lead to additional costs for monitoring and enforcement.
Impact of the carbon tax on businesses and consumers
To adapt to the carbon tax, businesses must improve their energy efficiency, innovate in low-carbon technologies, and adjust their business models to incorporate more sustainable practices. This adaptation often leads to higher prices for goods and services for consumers, due to the additional costs associated with taxing CO2 emissions. To limit the impact on households and vulnerable sectors, accompanying measures such as financial assistance, exemptions, or compensations are often put in place.
How does the carbon tax contribute to the energy transition?
The carbon tax contributes to the energy transition by generating revenue that can be reinvested in green projects, such as the development of renewable energy (solar, wind) and improving energy efficiency. By raising the cost of fossil fuels, it encourages businesses and consumers to change their behaviors, favoring low-carbon solutions. This tax helps achieve national and international climate goals, such as those of the Paris Agreement, by reducing greenhouse gas emissions and accelerating the energy transition toward a more sustainable model.
