You need to have a consistent method to get accurate results – especially if you are going to rely on lots of different people to collect and interpret data.
Good sources of standards include:
• Greenhouse Gas Protocol
Free set of commonly used standards
• International Organization for Standardization, ISO 14064
Builds on many of the concepts introduced by the GHG Protocol
Detailed Explanation
This chunk emphasizes the importance of using a standardized method to measure and calculate carbon footprints. A consistent method ensures that everyone involved in data gathering and interpretation gets accurate and reliable results. The Greenhouse Gas Protocol is a widely recognized source that provides standards for measuring emissions, while ISO 14064 builds on these principles to ensure international consistency.
Examples & Analogies
Consider a recipe for baking a cake. If everyone in the kitchen uses the same recipe (method), the cake turns out the same every time. But if one person decides to use different ingredients or measurements, the cake might not taste good. Similarly, using a standard method for carbon footprint calculations ensures that the results are consistent and reliable across different organizations.
Establishment of Assessment Boundaries

You will need to define:
• Organizational boundaries
What parts of the organization are included? This can be complex for large organizations with many subsidiaries, joint ventures or leased assets.
• Operational boundaries
All scope 1 and scope 2 emissions should be included, but the organization can choose which scope 3 emissions to include.
When choosing a boundary try to take account of how your organization works, other reporting periods, legislative requirements, and the practicalities of data collection.
Detailed Explanation
Establishing assessment boundaries involves defining which parts of your organization and its emissions will be included in the carbon footprint calculation. Organizational boundaries clarify which entities (like subsidiaries or joint ventures) are to be considered, while operational boundaries focus on which types of emissions (Scope 1, 2, and optional Scope 3) will be measured. This step is crucial to ensure the measurements are relevant and accurate.
Examples & Analogies
Imagine a school district with multiple schools. When calculating the district's carbon footprint, the district officials need to decide whether to include just the high school or all the schools within the district. Just like in the school district, determining boundaries helps to clarify the scope of what you're measuring, ensuring a more accurate assessment.
