Scope 1: Direct emissions from company-controlled sources (e.g., vehicles, heating systems).
Scope 2: Indirect emissions from purchased energy (e.g., electricity).
Scope 3: Indirect emissions across the value chain (e.g., supplier activities, product disposal).
Tools for Emissions Reporting
The Greenhouse Gas Protocol (GHGP) sets global standards for tracking emissions.
Platforms like neoeco automate emissions reporting by integrating financial data with carbon metrics, reducing errors and saving time.
Best Practices
Use reliable tools to measure Scope 1, 2, and 3 emissions.
Centralise documentation for audits.
Update methods as reporting standards evolve.
Key takeaway: Accurate emissions tracking and reporting are essential for B Corp certification. Tools like neoeco simplify the process and ensure compliance with global standards.
Greenhouse Gas (GHG) Baselining 101: Demystifying Scope 1, 2 & 3 Emissions Measurement
Scope 1, 2 & 3 Emissions in the B Corp Framework
The B Corp framework uses the Greenhouse Gas Protocol (GHG Protocol) to classify emissions into three categories, or "scopes." This system helps businesses identify their carbon sources and apply a standardised approach to measuring emissions.
Understanding these scopes is a key requirement for B Corp certification, as they form the basis of a company's climate strategy. Each scope captures a different type of emission, whether directly controlled by the business or influenced through its operations and supply chain. Let’s break these down, starting with Scope 1 emissions.
Scope 1: Direct Emissions
Scope 1 emissions come directly from sources that a company owns or controls.
These include things like company-operated vehicles, on-site heating systems, and industrial processes. For example, a fleet of delivery vans produces Scope 1 emissions through the combustion of diesel or petrol, while gas boilers used for heating also fall into this category. Manufacturing businesses typically report higher Scope 1 emissions due to energy-intensive operations, whereas service-based companies tend to have lower levels. Even small businesses with something as simple as a company car or a gas heating system need to account for these emissions.
Scope 2: Indirect Emissions from Purchased Energy
Scope 2 emissions are tied to the energy a business buys and uses, such as electricity. While these emissions occur at the power plant where the energy is generated, they are directly linked to the company's energy consumption.
For most businesses, electricity bills are the main source of Scope 2 emissions. The carbon intensity of these emissions depends on factors like the energy supplier and the mix of renewable versus non-renewable energy in the national grid. To lower Scope 2 emissions, businesses can switch to renewable energy tariffs or invest in on-site renewable energy systems, like solar panels.
Scope 3: Value Chain Emissions
Scope 3 emissions cover all other indirect emissions across a company’s entire value chain, both upstream (before the product or service reaches the company) and downstream (after it leaves).
Upstream emissions include those from purchased goods and services, business travel using third-party vehicles, employee commuting, and waste generated during operations. For instance, the carbon footprint of a business trip taken via commercial air travel is a type of upstream Scope 3 emission. Similarly, emissions from the production of office supplies, raw materials, or equipment fall into this category.
Downstream emissions, on the other hand, occur after a product or service leaves the company’s control. These include emissions from the transportation and distribution of products, the way customers use the product, and its disposal or recycling at the end of its life.
For service-based businesses, managing Scope 3 emissions can be particularly complex. However, tools like neoeco and other sustainability platforms simplify the process by categorising financial transactions directly linked to Scope 3 emissions. These platforms can integrate with financial systems to automatically identify which purchases contribute to Scope 3 and which energy costs are part of Scope 2, making the reporting process much more efficient.
Measuring emissions across all three scopes is vital for achieving B Corp certification, as it ensures a comprehensive view of a company’s carbon footprint.
Tools and Methods for Measuring and Reporting Emissions
To accurately report emissions, you need reliable tools and methods to measure and document your Scope 1, 2, and 3 carbon footprint. Below, we’ll look at the standard frameworks that form the backbone of effective emissions reporting.
Standard Methods for Emissions Reporting
The Greenhouse Gas Protocol (GHG Protocol) is the go-to framework for measuring Scope 1, 2, and 3 emissions. It provides a consistent methodology, ensuring your B Corp assessment aligns with internationally recognised standards.
For additional verification, ISO 14064 outlines requirements for assurance and validation of emissions data. This is especially important when external validation is needed for B Corp certification or regulatory compliance.
In the UK, businesses must also adhere to frameworks like the Streamlined Energy and Carbon Reporting (SECR) requirements and the UK Sustainability Reporting Standard (UK SRS). These frameworks build on the GHG Protocol but include specific disclosure rules for UK-based companies. Similarly, Australian businesses follow the Australian Sustainability Reporting Standards (ASRS 2).
Using these methodologies ensures consistency across organisations. When everyone measures emissions the same way, performance comparisons and progress tracking become more meaningful. However, manually implementing these standards can be labor-intensive and complex.
