Comparison: GHG protocol vs ISO 14064

There are two globally used and accepted protocols for GHG calculation, verification, and reporting - GHG protocol and ISO 14064.

The GHG Protocol and ISO 14064 are two distinct but related frameworks for measuring and managing greenhouse gas (GHG) emissions and carbon footprints. They are often used in conjunction to help organizations and governments address climate change and sustainability issues.

Here are the key differences between the two:

In summary, the GHG Protocol is a more business-oriented, practical tool for measuring and reporting GHG emissions. At the same time, ISO 14064 is a set of international standards that offer a more structured and rigorous approach to GHG accounting, verification, and project-based emissions reduction. Organizations may choose to use one or both of these frameworks depending on their specific needs and goals in addressing climate change and sustainability.

Both the GHG Protocol and ISO 14064 address Scope 3 emissions, which are indirect greenhouse gas emissions associated with an organization's value chain. While the core concept of Scope 3 emissions is consistent between the two frameworks, there may be some differences in how the emissions categories are defined or categorized. However, it's important to note that the GHG Protocol and ISO 14064 are complementary and can be used together, and they both provide a common basis for categorizing and reporting Scope 3 emissions.

While these categories are generally consistent between the GHG Protocol and ISO 14064, there may be subtle differences in how emissions are classified or reported. It's essential for organizations to carefully review the specific guidance provided by each framework to ensure they are reporting Scope 3 emissions accurately and in line with their reporting objectives. Additionally, both frameworks may evolve over time, so it's a good practice to refer to the latest versions and guidelines for the most up-to-date information.

Conclusion

When determining which standard to follow for GHG accounting and management, there are several factors to consider, such as purpose, scope, audience, resources, and preferences. The GHG Protocol is a comprehensive and detailed standard that covers all aspects of GHG accounting and management and is aligned with most voluntary and mandatory reporting programs. Alternatively, ISO 14064 is a more generic and concise standard that focuses on the requirements and specifications for GHG quantification, monitoring, reporting, and verification. Both standards are compatible and complementary; you can use the GHG Protocol to identify and calculate your GHG emissions and removals, then use the ISO 14064 to report and verify them.
