CO₂ Tax Rates by Country

The countries that implemented tax on CO2 and the tax rates imposed are as follows, and these rates are also subject to change over time. Below are some approximate figures and structures to give you an idea:

European Countries

• Sweden: One of the highest carbon tax rates in the world, around €115 per tonne of CO2 as of 2020.
• Norway: Varies by sector but ranges from €23 to €64 per tonne of CO2.
• Finland: Approximately €62 per tonne of CO2 as of 2020.
• Denmark: Roughly €24 per tonne of CO2 as of 2020.
• Switzerland: About €85 per tonne of CO2 as of 2020.
• Ireland: €33.50 per tonne of CO2 as of 2021, with plans to raise it to €80 by 2030.
• France: Around €44.60 per tonne of CO2 as of 2018, but proposals to increase it were put on hold due to public protests.
• United Kingdom: The carbon price floor was at £18 per tonne of CO2 as of 2020.

North America

• Canada: Started at CAD 20 per tonne of CO2 in 2019 and plans to increase to CAD 170 by 2030.
• United States: Has no federal carbon tax, some states like California have cap-and-trade systems.

Other Countries

• South Africa: Around ZAR 120 (approximately €7) per tonne of CO2 as of 2019.
• Japan: Approximately JPY 289 (roughly €2.20) per tonne of CO2.
• Singapore: S$5 (about €3) per tonne of CO2, with plans to review and possibly increase to S$10-15 by 2023.
• New Zealand: Has an Emissions Trading Scheme, not a tax, but the price of emissions can vary—ranging from NZD 20 to NZD 50 per tonne of CO2.
• Iceland: About ISK 5,000 (roughly €32) per tonne of CO2 as of 2020.

Carbon Tax Rates by Country as of 2020-2021

These figures are approximate and can change over time due to inflation, political decisions, and other factors.

It's crucial to note that the impact of a carbon tax will be profound if spent exclusively towards CO2 mitigation and renewable sources and developing newer technologies.
