Net zero refers to the concept of achieving a balance between the amount of greenhouse gases emitted and the amount removed from the atmosphere. This is typically achieved by reducing emissions as much as possible and offsetting any remaining emissions through activities such as planting trees or investing in renewable energy projects. Net zero is a key goal in the fight against climate change, as it aims to minimize the impact of human activities on the environment and limit the global temperature rise to less than 1.5 degrees Celsius. Many countries, companies, and organizations have set targets to achieve net zero emissions by a certain date, typically by mid-century.
