Carbon offsetting is a way to balance out the carbon dioxide emissions produced by an individual, company, or activity. This is done by investing in projects that reduce or capture an equivalent amount of carbon dioxide from the atmosphere. Common projects include reforestation, renewable energy, and energy efficiency initiatives. By purchasing carbon offsets, people and organizations can take responsibility for their carbon footprint. For example, if a flight generates a certain amount of emissions, travelers can buy offsets to support projects that help reduce that same amount of carbon, effectively neutralizing their impact on the environment.
