The Greenhouse Gas (GHG) Protocol is a comprehensive global framework crucial for measuring and managing greenhouse gas emissions. Launched in 1998 by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), its primary goal is to offer a standardized approach for corporations and organizations to measure and manage their emissions effectively. This enables them to fully grasp and minimize their climate impact. The Protocol has recently risen in prominence due to an increased awareness of climate change and the pressing demand for immediate action. More organizations are pledging allegiance to sustainability, emphasizing the need for transparency and accountability regarding their environmental contributions. As a result, the GHG Protocol has become an essential instrument in the global crusade against climate change, fostering consistent and comparable emissions reporting that fuels effective climate action strategies. 

GHG Protocol Emission 2 is a critical component of the Global Greenhouse Gas Protocol, designed to provide a clear framework for measuring and managing emissions. This section of the protocol is vital for organizations aiming to understand their environmental impact and comply with global standards. Through its detailed methodology and compliance guidelines, GHG Protocol Emission 2 plays a crucial role in the global effort to mitigate climate change. 

In this blog, we are going to explore the intricacies of Scope 2 emissions, focusing on how organizations can accurately measure, report, and ultimately reduce their indirect greenhouse gas emissions. 

Understanding GHG Protocol Emission 2 

GHG Protocol Emission 2 includes emissions from the consumption of purchased electricity, steam, heating, and cooling. For numerous corporations, the procurement of electricity accounts for a substantial portion of their greenhouse gas emissions and presents a prime opportunity for emission reduction. By including Scope 2 in their evaluations, companies can effectively gauge the risks and benefits related to shifts in electricity costs and greenhouse gas emission expenses. 

GHG Protocol Emission 2, when compared to other GHG Protocol scopes, offers a distinct set of challenges and opportunities. Unlike Scope 1 emissions, where companies have direct control, Scope 2 emissions compel companies to collaborate with suppliers and utility providers. This interaction paves the way for substantial sustainability improvements, notably through adopting renewable energy practices and energy efficiency initiatives. In contrast, Scope 1 emissions are directly produced by the company, and Scope 3 emissions, which include all other indirect emissions that occur in a company’s value chain, also present their own unique challenges in measurement and management, further emphasizing the complexity and potential of Scope 2 for driving sustainable change. 

Scope and Coverage 

The GHG Protocol includes the measurement and reporting of six primary greenhouse gases (GHGs) as defined by the Kyoto Protocol and commonly referred to as “Kyoto gases.” These gases are crucial contributors to global warming and climate change. Here’s an explanation of each greenhouse gas included in the protocol:

1. Carbon Dioxide (CO2): CO2 is the most prevalent greenhouse gas emitted by human activities, primarily through the combustion of fossil fuels such as coal, oil, and natural gas. It is also released through deforestation and other land-use changes.

2. Methane (CH4): CH4 is emitted during the production and transport of coal, oil, and natural gas. It is also produced by livestock digestion, agricultural activities, landfills, and the decay of organic waste in anaerobic conditions.

3. Nitrous Oxide (N2O): N2O is emitted from agricultural and industrial activities, including fertilizer use, livestock manure management, combustion of fossil fuels, and certain industrial processes such as adipic acid production and wastewater treatment.

4. Hydrofluorocarbons (HFCs): HFCs are synthetic greenhouse gases used primarily in refrigeration, air conditioning, foam blowing, and other industrial applications as substitutes for ozone-depleting substances. They have high global warming potentials (GWPs) compared to CO2.

5. Perfluorocarbons (PFCs): PFCs are synthetic gases used in various industrial applications, including aluminum production, semiconductor manufacturing, and electronics production. They have extremely high GWPs and long atmospheric lifetimes.

6. Sulfur Hexafluoride (SF6): SF6 is a synthetic gas primarily used in electrical transmission and distribution equipment, such as circuit breakers and switchgear. It has a very high GWP and can remain in the atmosphere for thousands of years.

By accounting for these six greenhouse gases in emissions inventories and reporting, organizations can assess their contributions to climate change accurately and develop strategies to mitigate their impact on the environment.

Methodology and Calculation 

The methodology underpinning GHG Protocol Emission 2 emphasizes the calculation of carbon emissions from energy consumption. One of the key principles involves distinguishing between “market-based” and “location-based” approaches, allowing organizations to reflect the effect of contractual instruments (e.g., renewable energy purchases) in their reported emissions. 

Location-based Method (also known as Grid Average Method): 

• This method calculates emissions based on the average emissions intensity of the electricity grid where the organization operates. It considers the emissions associated with the generation of electricity consumed by the organization, without accounting for any specific purchasing decisions. 
• Calculation: Emissions are calculated using emission factors based on the average emissions intensity of electricity generation in the geographical region or grid where the organization is located. 
• Application: Suitable for organizations that do not have access to specific information about the sources of electricity they consume, or when detailed data on electricity purchases is unavailable.

Market-based Method (also known as Contractual Instruments Method): 

• This method calculates emissions based on the specific contractual instruments or renewable energy purchases made by the organization. It reflects the emissions associated with the actual sources of electricity consumed, taking into account any renewable energy certificates (RECs) or other market-based instruments. 
• Calculation: Emissions are calculated based on the emissions intensity associated with the specific sources of electricity purchased by the organization, considering any renewable energy purchases or offsets. 
• Application: Suitable for organizations that have access to detailed information about their electricity purchases and want to accurately reflect the environmental attributes of their energy consumption, including any renewable energy commitments. 

These two methodologies offer flexibility for organizations to choose the approach that best aligns with their data availability, reporting goals, and sustainability objectives. 

Calculating emissions under GHG Protocol Emission 2 involves several steps, including data collection on energy use, selection of the appropriate emission factors, and the application of relevant conversion factors. The process is meticulous, demanding accuracy and transparency to ensure the integrity of the carbon inventory. 

• Consistency and Accuracy: The calculation process prioritizes consistency and accuracy to ensure that emissions data is reliable and comparable over time. Consistent methodologies and data sources are essential for meaningful emissions tracking and reporting. 
• Emission Factors: Emission factors are fundamental in emission calculations. These factors represent the amount of greenhouse gases emitted per unit of activity or energy consumption. They are typically expressed in terms of CO2 equivalent (CO2e) and vary based on factors such as fuel type, energy source, and emission control technologies. 
• Global Warming Potentials (GWPs): GWPs are used to account for the varying potency of different greenhouse gases in contributing to global warming over specific time periods. For example, methane (CH4) has a higher GWP than carbon dioxide (CO2) over a shorter time horizon, reflecting its stronger heat-trapping potential. 
• Activity Data: Accurate activity data, such as energy consumption, fuel usage, production output, or vehicle mileage, is crucial for emission calculations. Organizations must collect and maintain detailed records of their activities to support emissions quantification. 

Compliance and Reporting 

Compliance with GHG Protocol Emission 2 entails adhering to standardized methodologies for calculating and reporting greenhouse gas emissions. This includes comprehensive coverage of emissions across Scope 1, Scope 2, and potentially Scope 3 sources. Organizations must maintain accurate data integrity and undergo quality assurance procedures to validate emission data. Timely reporting and transparent disclosure of emissions data and methodologies are essential for accountability and stakeholder understanding. Compliance may also involve meeting regulatory requirements and demonstrating continuous improvement in emissions management practices. Overall, adherence to GHG Protocol Emission 2 standards enhances transparency, credibility, and accountability in emissions reporting, supporting sustainable business practices and environmental responsibility.
