Trusting a carbon footprint calculation involves ensuring it adheres to recognized standards, covers all relevant emission sources, uses accurate emission factors, is conducted by qualified entities, and has undergone verification. Implementing the calculation’s findings towards sustainability goals further validates its reliability.
What standards should a reliable carbon footprint calculation follow?
To determine the reliability of a carbon footprint calculation, first, check if it’s based on established standards. These standards, such as the Greenhouse Gas Protocol and ESRS E1 for organizational emissions and ISO 14067 for carbon footprint calculation of products, ensure consistency and thoroughness in accounting for emissions. A calculation not grounded in these standards could merely be an estimation, lacking the rigor and accountability required for accuracy.
How are relevant emission sources identified and accounted for?
Ensuring all relevant emission sources are included in the carbon footprint calculation is crucial. This encompasses direct emissions from owned or controlled sources, indirect emissions from the generation of purchased energy, and all other indirect emissions that occur in the value chain. Although sometimes believed otherwise, calculating indirect Scope 3 emissions generated in the value chain is not voluntary if the company complies with GHG Protocol standards. Missing out on any emission source can lead to underreporting and inaccuracies.
- Direct Emissions: Company vehicles, manufacturing processes (Scope 1)
- Indirect Emissions: Purchased electricity (Scope 2)
- Indirect Emissions from value chain: Purchased products and services, transportations, wastes, business travelling, etc. (Scope 3)
What process is involved in selecting the correct emission factors?
Selecting accurate emission factors is essential for a trustworthy carbon footprint calculation. Emission factors are coefficients that estimate the amount of gases released into the atmosphere as a result of various activities. They vary by region, activity type, and over time. Relying on outdated or inappropriate emission factors can skew results significantly.
Emissions calculations should primarily use emission factors based on primary data obtained from suppliers. If all primary factors are not available, average emission factors based on physical data are used. The last option is to use spend-based factors if no other options are available. The OpenCO2 emissions database contains approximately 8,000 up-to-date and expert-validated emission factors for companies’ needs.
Who is qualified to conduct a carbon footprint calculation?
The expertise of the individual or organization conducting the carbon footprint calculation greatly influences its reliability. Professionals with a background in environmental science, engineering, or a related field, and who are familiar with the applicable standards and methodologies, are best suited for this task.
What does verification entail for carbon footprint calculations?
Verification of a carbon footprint calculation by an independent third party ensures that the calculation has been conducted accurately and objectively. This process often involves a detailed review of the methodology, emission factors used, and the overall approach. The benefits of verification include increased reliability of calculations. Reliable calculations facilitate emission reductions and operational improvements. Independent verification provides unbiased confirmation of accuracy which can be important for various stakeholders in a company, such as customers or investors.
How should the results of a carbon footprint calculation be utilized?
The ultimate test of a carbon footprint calculation’s reliability is how its results are used to inform sustainability strategies. Actionable insights should lead to meaningful reductions in emissions through targeted strategies. The results of carbon footprint calculation can be used for:
- Product development
- Developing sustainable development strategies
- Setting reduction targets
Emissions accounting does not directly increase a company’s responsibility, but it does provide a baseline and information about where emissions originate and where they need to be reduced. Emissions reduction targets set by companies, such as SBTi targets, should be aligned with the Paris Agreement.
