Scope 3 GHG Emissions Inventory

Customized Professional Services Offerings

Understanding your company’s Scope 3 emissions is considered best practice for anyone looking to advance their sustainability initiatives, improve performance, and build credibility.

G&A’s GHG emissions methodology and calculations are aligned with the GHG Protocol Corporate and Accounting and Reporting Standard and the Corporate Value Chain (Scope 3) Standard, both of which are widely accepted global standardized frameworks to measure and manage GHG emissions from private and public sector organizations. By using these standards, G&A will ensure that the Scope 3 inventory is complete, accurate, and ready for assurance by an independent third party.

For most companies, Scope 3 emissions make up the majority of their total emissions footprint, which makes accounting for Scope 3 emissions an important step in completing a comprehensive corporate GHG emissions inventory. 

Measuring and reporting Scope 3 emissions will prepare you for compliance with existing and emerging regulations and allow you to respond to a variety of sustainability reporting frameworks.  

Our in-house ESG and sustainability reporting team can help you efficiently and effectively report the results of your greenhouse gas emission inventory under a variety of frameworks, including CDP, ISSB, GRI, TCFD, and prepare any applicable disclosures, such as California climate laws (SB 253 and AB 1305) and the SEC rule on climate-related disclosures.
