Yes, there are standardised methodologies for calculating carbon footprints to ensure consistency and comparability. These methodologies ensure consistency in emission calculations, enable benchmarking, and enhance transparency in reporting, making it easier for businesses to measure and manage their carbon footprints effectively. Some widely recognised methodologies include:
- The Greenhouse Gas Protocol (GHGP): Developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), GHGP provides guidelines for calculating emissions across the three Scopes.
- ISO 14064: This international standard outlines principles and requirements for quantifying and reporting greenhouse gas emissions and removals.
- PAS 2050: A standard by the British Standards Institution (BSI) that focuses on product carbon footprint assessment.
- Carbon Trust Standard: This certification recognises organisations' efforts in measuring, managing, and reducing carbon emissions.
- Life Cycle Assessment (LCA): A comprehensive methodology that evaluates the environmental impact of products or activities, including carbon emissions.
