Mastering Data Collection for Carbon Footprint Calculation

Calculating your organisation’s carbon footprint is a pivotal step toward sustainability. Accurate data collection, guided by the Greenhouse Gas (GHG) Protocol, ensures that your efforts are both effective and credible. This guide outlines the essentials of data collection for carbon footprint calculation, adhering to the principles of the GHG Protocol.

What is the GHG Protocol?

The GHG Protocol is the globally recognised standard for measuring and managing greenhouse gas emissions. It categorises emissions into three scopes:

• Scope 1: Direct emissions from owned or controlled sources, such as company vehicles or on-site fuel combustion.
• Scope 2: Indirect emissions from the generation of purchased electricity, steam, heating, and cooling consumed by the company.
• Scope 3: All other indirect emissions that occur in the value chain, including both upstream and downstream activities. This encompasses 15 categories, such as purchased goods and services, business travel, and waste disposal.

Principles of Data Collection According to the GHG Protocol

Effective data collection is underpinned by five key principles:

1. Relevance: Ensure the GHG inventory appropriately reflects the company’s emissions and serves the decision-making needs of users.
2. Completeness: Account for all emission sources within the chosen inventory boundary.
3. Consistency: Use consistent methodologies to allow for meaningful comparisons of emissions over time.
4. Transparency: Address all relevant issues in a factual and coherent manner, based on a clear audit trail.
5. Accuracy: Ensure that GHG emissions calculations are neither systematically over nor under actual emissions, and that uncertainties are reduced as far as practicable.

Steps in the Data Collection Process

1. Define Organisational and Operational Boundaries: Determine the scope of your GHG inventory by identifying which operations you own or control and decide on a consolidation approach (equity share, financial control, or operational control). If you are an NHS provider before 2027, you will only need to do a subset of your scope 3 emissions.
2. Identify Relevant Emission Sources: Categorise your emissions into Scope 1, 2, and 3. For many organisations, Scope 3 emissions represent the largest portion of their carbon footprint.
3. Collect Activity Data: Gather data on activities that result in GHG emissions. This includes:
   • Energy Consumption: Electricity, heating, and cooling usage.
   • Fuel Usage: Quantities of fuels consumed on-site or by company vehicles.
   • Transportation: Business travel distances and modes, employee commuting patterns.
   • Procurement: Details of purchased goods and services.
   • Waste Management: Volumes and disposal methods of waste generated.
4. Apply Emission Factors: Convert activity data into GHG emissions using appropriate emission factors. Ensure these factors are up-to-date and relevant to your region and sector.
5. Ensure Data Quality: Implement procedures for data validation and verification to maintain accuracy and reliability.

Common Challenges and Solutions

Accessing comprehensive data, particularly for Scope 3 emissions, can be a significant challenge. It’s essential to engage with suppliers and partners early in the process to facilitate data sharing. Where data is unprocessed or difficult to interpret, employing experts or leveraging technology can help extract meaningful insights from existing raw datasets.

Inconsistent data formats and varying measurement units can make analysis difficult and reduce the reliability of results. To mitigate this, standardising data collection templates and offering clear guidance to data providers is key. This ensures that the data you receive is both consistent and comparable.

When data is incomplete or unavailable, using proxy data or estimation methods may be necessary. However, it is important to do this with care. Any assumptions made should be clearly documented to maintain transparency. Reviewing how others in your sector have handled similar challenges can provide useful benchmarks, as comparability is critical for producing credible and useful results.

Leveraging Technology for Efficient Data Collection

Utilising specialised software can streamline the data collection process, enhance accuracy, and facilitate real-time monitoring. Automation reduces manual errors and allows for more efficient data management.

Conclusion

Accurate data collection is the foundation of effective carbon management. By adhering to the GHG Protocol’s principles and systematically addressing data collection challenges, organisations can develop a credible GHG inventory. This not only aids in regulatory compliance but also informs strategic decisions toward sustainability goals.
