A carbon tax is a financial charge imposed on companies and individuals based on the amount of carbon dioxide (CO2) emissions they produce. The goal of this tax is to encourage businesses and consumers to reduce their carbon footprint by using cleaner energy sources and adopting more sustainable practices. By making fossil fuels more expensive, a carbon tax aims to promote environmental responsibility and combat climate change. The revenue generated from a carbon tax can be used to fund renewable energy projects, improve public transportation, or support communities affected by climate policies. Many countries and regions, including parts of Canada and Europe, have implemented carbon taxes as part of their efforts to meet climate change goals and reduce greenhouse gas emissions.
