Carbon accounting is the process of identifying, calculating, organizing, and reporting an organization’s greenhouse gas emissions across direct operations, purchased energy, and the value chain.
A corporate greenhouse gas inventory typically groups emissions into Scope 1, Scope 2, and Scope 3. The inventory establishes a baseline for decisions, reduction planning, customer responses, reporting, and certifications. Good carbon accounting also documents boundaries, data sources, methods, assumptions, factors, exclusions, and changes so results can be explained and improved.
Scope 1 covers direct emissions from sources a company owns or controls; Scope 2 covers emissions associated with purchased electricity, steam, heat, or cooling; Scope 3 covers other indirect value-chain emissions.
Scope 3 can include purchased goods and services, capital goods, fuel- and energy-related activity, transportation, waste, business travel, employee commuting, leased assets, product use, and other upstream or downstream categories. Not every category is equally relevant to every company. Aclymate helps teams identify applicable sources, collect available data, estimate gaps, and improve the inventory over time.
Aclymate follows the GHG Protocol Corporate Accounting and Reporting Standard and uses recognized emissions factors from sources such as the EPA, IPCC, DEFRA, and other established databases.
The methodology connects business activity data to appropriate emissions factors and keeps results organized by scope, category, activity, location, supplier, or other relevant dimension. Methodology choices should be documented because factors, organizational boundaries, market-based electricity treatment, Scope 3 methods, and data quality can affect results. Customers seeking audit or assurance should confirm the required methodology and evidence with their verifier.
Spend-based accounting estimates emissions from dollars spent and industry-average factors, while activity-based accounting uses physical activity such as kilowatt-hours, gallons, miles, weight, or units.
Spend-based data is often the fastest way to establish a broad Scope 3 baseline from accounting records. Activity-based or supplier-specific data is usually more precise when reliable quantities and factors are available. Aclymate supports a practical progression: start with the data the company has, identify the largest or most important categories, and replace estimates with stronger data where the improvement matters.
Aclymate can use utility, fuel, vehicle, travel, freight, purchasing, accounting, supplier, product, facility, employee, waste, and other operational data.
Data can come from uploaded files, connected accounting or financial systems, utilities, ERP systems, travel and expense sources, supplier surveys, product records, and manual inputs. The best source depends on the emissions category and reporting purpose. Aclymate’s integration and services model helps customers locate, map, clean, and organize those inputs rather than leaving them to build the entire data pipeline alone.
Accuracy depends on data completeness, data quality, method selection, emissions factors, and how well the organizational and operational boundaries reflect the business.
Explorer intentionally provides a directional estimate for early-stage decisions. Navigator supports more complete carbon accounting and stronger data workflows. Aclymate One adds expert review, bookkeeping, and gap identification. No software can make incomplete source data precise by itself, so Aclymate emphasizes transparency, documentation, and progressive improvement. Independent assurance or audit is a separate engagement when required.
Aclymate is designed to identify missing data, preserve source information, document methodology, and distinguish directional estimates from more complete accounting.
A defensible inventory should explain organizational boundaries, reporting periods, source data, estimation methods, emission factors, exclusions, and material limitations. Explorer should clearly label its directional nature. Navigator and Aclymate One can support stronger source records and review, but independent assurance remains separate when required.
CO2e, or carbon-dioxide equivalent, converts the warming impact of different greenhouse gases into one comparable unit.
A carbon footprint can include carbon dioxide, methane, nitrous oxide, and other greenhouse gases. CO2e applies recognized global-warming potentials so organizations can aggregate those gases into a common measure. The selected factor set and reporting standard should be documented because methodologies can change over time.
