Carbon Accounting and Greenhouse Gas Inventory

A GHG inventory is a comprehensive accounting of an organization’s greenhouse gas emissions across Scope 1 (direct), Scope 2 (indirect from energy), and Scope 3 (value chain). It forms the foundation for climate strategy, regulatory compliance, and ESG reporting.

Any organization with sustainability goals, regulatory obligations (e.g., California SB 253, CSRD), or ESG reporting requirements (e.g., CDP, TCFD, SBTi) should develop a GHG inventory. It’s especially critical for organizations who need to meet investor or buyer requests for GHG emissions data and reduction targets.

SCS Consulting Services works across sectors including manufacturing, finance, agriculture, consumer goods, and more. Our team tailors GHG inventories to each client’s operations, emissions sources, and reporting needs.

• Scope 1 and 2 emissions calculation
• Scope 3 screening and hybrid inventories — using a mix of activity and proxy data
• Emissions factor sourcing and documentation
• Reporting outputs aligned with GHG Protocol, CDP, and SBTi
• Optional Inventory Management Plan (IMP)
• Optional emissions factor calculations through our LCA-based Product Carbon Footprinting services 

Timelines vary based on company size, data availability, and Scope 3 complexity. Most inventories are completed in 6-12 weeks, with faster turnarounds possible for focused Scope 1 and 2 assessments. 

Our consultants have decades of combined experience with GHG accounting and apply scientific rigor with practical, industry-specific insights. Our industry experts combine peer benchmarking, research, and the latest IPCC accounting protocols to identify initiatives that will maximize the return on investment given the emission hotspots identified in a comprehensive GHG emissions inventory.

In addition, SCS Consulting Services has the ability to go beyond the standard reporting of CO2e over a 100-year timeframe and can break out each greenhouse gas and super pollutant (methane, black carbon, etc.) to show how a reduction in each gas can impact near term heat and maximize your reductions per dollar of investment.

Our services meet global standards for credibility and transparency, reference the latest emissions factors, and follow the GHG Protocol. We also prepare outputs suitable for independent review and assurance. At every step of the way, we support our clients to provide accurate climate impact disclosures that align with regulatory requirements as well as standards and frameworks like IFRS S2, CSRD, GRI, TCFD, CDP, and SBTi.

No problem. SCS Consulting Services specializes in working with first-time reporters and can guide you through every step — from data collection to final reporting — with training and templates included. 

Each carbon footprint is unique based on company size, scopes being assessed and type of business or industry. To receive an estimate on what it would cost your organization to develop a carbon footprint, we recommend scheduling a meeting with us.
