What Is a Corporate Carbon Footprint?
A corporate carbon footprint measures the total greenhouse gas emissions a company releases into the atmosphere as a result of its activities. This calculation covers a broad range of activities — from energy consumption and supply chains to waste management and transportation. Calculating the corporate carbon footprint allows companies to understand their environmental impact, develop strategies to reduce it, and define sustainability targets. By measuring their corporate carbon footprint, companies can also meet reporting requirements, take aligned action, and avoid financial liabilities.
How Is a Corporate Carbon Footprint Calculated?
Calculating a corporate carbon footprint is a complex process. For this reason, companies that want to perform the calculation often work with third-party providers. Still, to see how these calculations work, we can break the process down into five core steps.
1. Defining the Scope
Before calculating their carbon footprint, companies must determine the emission sources that will be included. First, they need to decide which business units or facilities will be part of the calculation.
Next, the scope of the calculations is defined. These scopes are:
- Scope 1 (Direct Emissions): These are the direct emissions generated at a company's own facilities. Emissions from fossil fuels burned in the company's buildings or vehicles are examined under this scope.
- Scope 2 (Indirect Energy Emissions): These are emissions from energy the company consumes. They include emissions from the generation of any energy purchased, such as electricity.
- Scope 3 (Operational Emissions): These cover emissions from processes like supply chain, business travel, and waste management. Because it requires a wide range of data, it is the most challenging scope to calculate.
2. Data Collection
Before performing carbon footprint calculations, the most important step is data collection. This is a critical step to avoid errors in time-consuming calculations and to simplify them with well-classified data. In this step, mandatory inputs such as energy consumption, logistics data, waste and water management, and fuel consumption need to be listed in a reliable, categorized way.
3. Calculation with Emission Factors
Next, the collected data is multiplied by emission factors to calculate the carbon emissions. Emission factors are numerical coefficients that convert consumed fuels into CO2 equivalent. The formula is simple:
Carbon Footprint = Fuel Consumption x Emission Factor
Emission factors can be obtained from national or international sources. Which source to use depends on the authority or party to whom you are reporting. For example, factors can be taken from organizations such as the IPCC (Intergovernmental Panel on Climate Change) or the EPA (Environmental Protection Agency).
Different greenhouse gases have different levels of climate impact. For this reason, calculations are converted into CO2 equivalent to create a common language. For example, methane (CH4) is 25 times more potent as a greenhouse gas than CO2. In this conversion, each emitted greenhouse gas is multiplied by its global warming potential (GWP) to obtain the equivalent value.
4. Reporting and Analysis
Once emissions have been calculated, they are compiled into reports so that impacts can be more easily understood and analyzed. At this point, companies need to prepare reports in specific formats aligned with their own goals and the requirements of the parties to whom they're reporting. These can follow formats such as ISO 14064 or the GHG Protocol.
5. Reduction Strategies
Once calculation and reporting are complete, the next task for companies is regulatory compliance. To comply with regulations and avoid the carbon taxes that will increasingly enter our lives, companies need to reduce their carbon footprint. Based on the prepared reports, they need to develop reduction strategies such as improving energy efficiency, using renewable energy, and optimizing supply chain choices.
Conclusion
The corporate carbon footprint is a widely discussed topic today. What makes it so important is the sustainability regulations introduced by the EU and the UN as global warming has become a critical issue. While current regulations require companies to calculate their carbon footprint and present it in various forms, future updates will add financial obligations tied to the emissions covered in these calculations.
Above, we briefly explained how a corporate carbon footprint is calculated. However, along with calculation, topics like reporting, analysis, and reduction strategies require expertise from quality engineers as well as specialized environmental engineers. For this reason, companies that want to carry out these calculations typically either build a dedicated sustainability team or engage a third-party provider to work alongside their quality team.
