GHG emissions are gases that trap heat in the atmosphere and contribute to global warming. Calculating emissions is crucial for businesses to understand their environmental impact. Emissions are categorized into three scopes: Scope 1 (direct), Scope 2 (indirect), and Scope 3 (difficult to quantify). Gathering accurate data is the first step, followed by applying emission factors to convert data to CO2e. Various resources and guides are available to assist in the calculation process. Third-party verification adds credibility. Overall, accurate measurement and continuous improvement are essential for effective GHG management.
