Carbon pricing is expanding worldwide, affecting households, businesses, and industries. Our Carbon Tax Calculator helps you estimate your annual carbon tax liability based on your energy consumption, fuel use, and local tax rates. Whether you're budgeting for household expenses, planning business costs, or evaluating emission reduction strategies, understand exactly how carbon pricing impacts your bottom line.
A carbon tax is a fee placed on greenhouse gas emissions, typically charged per tonne of CO₂ equivalent. It creates a financial incentive to reduce emissions by making fossil fuel consumption more expensive. Carbon pricing comes in two main forms: direct carbon taxes (fixed price per tonne) and cap-and-trade systems (tradeable emission permits). As of 2024, over 70 jurisdictions worldwide have implemented carbon pricing, with rates ranging from $5 to over $130 per tonne CO₂.
Carbon Tax Formula
Tax = Emissions (tonnes CO₂e) × Tax Rate ($/tonne)Anticipate annual carbon tax costs for household or business financial planning.

A carbon tax sets a fixed price per tonne of CO₂, giving price certainty but variable emission reductions. Cap-and-trade sets a total emission limit and lets the market determine the price through tradeable permits, giving emission certainty but variable costs. Both create financial incentives to reduce emissions. Some jurisdictions use one or the other; some use both.
