When it comes to corporate sustainability, Scope 2 emissions are often one of the most straightforward areas to tackle. These emissions, which stem from purchased electricity, heating, and cooling, are a key part of any organisation’s carbon footprint. By understanding how Scope 2 emissions work, businesses can identify clear opportunities to decarbonise and improve their environmental impact.
Here we will break down the essentials of Scope 2 emissions, explore the nuances of accounting methods, and highlight actionable strategies for reduction.
What Are Scope 2 Emissions?
Scope 2 emissions are indirect greenhouse gas (GHG) emissions generated by the production of energy that an organisation purchases and consumes. This includes electricity, heating, cooling, and steam sourced from external providers. While these emissions don’t occur directly within a company’s operations, they are a critical part of its overall carbon footprint.
For example, if your business purchases electricity from a grid powered by fossil fuels, the emissions from generating that electricity are classified as Scope 2. These emissions are distinct from Scope 1 (direct emissions from owned or controlled sources) and Scope 3 (indirect emissions from the value chain).
Understanding Scope 2 is essential because it’s often one of the easiest emission categories to measure and address, thanks to the availability of data and market-based solutions.
Market-Based vs. Location-Based Accounting
One of the most important aspects of Scope 2 emissions is how they are calculated. The Greenhouse Gas Protocol outlines two distinct approaches:
1. Location-Based Accounting
This method calculates emissions based on the average emissions intensity of the local grid where energy consumption occurs. It reflects the energy mix of the region (e.g., coal, natural gas, renewables) and provides a standardised view of emissions.
For instance, if your office is in a region where the grid is 70% powered by coal, your location-based emissions will reflect that high-carbon energy mix
2. Market-Based Accounting
This approach accounts for emissions based on the specific energy products a company purchases. If your organisation buys renewable energy certificates (RECs) or contracts directly with a green energy provider, your market-based emissions could be significantly lower than the location-based calculation.
Both methods have their place in reporting, but market-based accounting offers businesses a way to actively reduce their Scope 2 footprint by choosing cleaner energy sources.
Emission Factors and Energy Mix
Emission factors are central to calculating Scope 2 emissions. These factors represent the amount of GHG emissions produced per unit of energy consumed (e.g., kilograms of CO2 per kilowatt-hour).
The energy mix of a region or provider heavily influences these factors. A grid powered predominantly by renewable sources like wind, solar, or hydroelectric will have a much lower emission factor than one reliant on coal or natural gas.
For businesses, understanding emission factors is crucial for identifying high-impact areas and prioritising energy efficiency or renewable energy procurement. Tools like the International Energy Agency’s (IEA) emissions database or national grid reports can provide reliable emission factor data.
Green Electricity and Certificates
One of the most effective ways to reduce Scope 2 emissions is by purchasing green electricity or renewable energy certificates (RECs). These instruments allow businesses to support renewable energy generation and claim the associated environmental benefits.
Guarantees of Origin (GOs)
In Europe, Guarantees of Origin (GOs) certify that a specific amount of electricity was generated from renewable sources. By purchasing GOs, companies can match their energy consumption with renewable generation, reducing their market-based Scope 2 emissions.
Renewable Energy Certificates (RECs)
In the United States, RECs serve a similar purpose. Each REC represents one megawatt-hour (MWh) of renewable energy generated and delivered to the grid. By buying RECs, businesses can effectively offset their electricity consumption with renewable energy.
Power Purchase Agreements (PPAs)
For organisations looking for a more direct approach, power purchase agreements (PPAs) allow them to contract directly with renewable energy producers. This not only reduces emissions but also provides financial support for new renewable projects.
Investing in green electricity and certificates is a practical way to decarbonise Scope 2 emissions, but it’s essential to ensure transparency and credibility in reporting.
Opportunities for Reduction and Reporting Clarity
Reducing Scope 2 emissions doesn’t have to be complicated. Here are some actionable steps businesses can take:
1. Energy Efficiency
Improving energy efficiency is often the easiest and most cost-effective way to reduce emissions. Upgrading to energy-efficient lighting, HVAC systems, and equipment can significantly lower electricity consumption.
2. Switch to Renewable Energy
Transitioning to renewable energy sources, either through direct procurement or certificates, is a powerful way to cut emissions. Evaluate options like GOs, RECs, or PPAs based on your region and energy needs.
3. On-Site Renewable Generation
Installing on-site renewable energy systems, such as solar panels, can provide a direct and visible reduction in Scope 2 emissions. While this requires upfront investment, it offers long-term savings and energy independence.
4. Engage Suppliers
If your organisation operates in leased spaces, work with landlords or facility managers to advocate for renewable energy procurement. Collaborative efforts can amplify impact.
5. Transparent Reporting
Clear and accurate reporting is essential for building trust with stakeholders. Use both location-based and market-based methods to provide a comprehensive view of your emissions. Ensure that any claims about renewable energy use are backed by credible certificates or agreements.
The Bottom Line
Scope 2 emissions represent a significant opportunity for businesses to make meaningful progress toward decarbonisation. By understanding the basics of purchased energy, leveraging market-based solutions, and investing in renewable energy, organisations can reduce their carbon footprint while meeting stakeholder expectations.
For ESG and sustainability professionals, Scope 2 is a manageable and impactful area to address and can deliver both environmental and reputational benefits.
