- Find deeper guidance for each scope and calculation method
What is a corporate carbon footprint?
A Corporate Carbon Footprint (CCF) is a comprehensive inventory of all greenhouse gas emissions your organization is responsible for. It typically covers one calendar or fiscal year. CCFs are structured using the GHG Protocol Corporate Accounting and Reporting Standard , which organizes emissions into three scopes:
| Scope | Description | Examples |
|---|---|---|
| Scope 1 | Direct emissions from sources owned or controlled by the organization | Fuel combustion in boilers, furnaces, and company vehicles |
| Scope 2 | Indirect emissions from purchased energy | Purchased electricity, district heating, cooling, and steam |
| Scope 3 | All other indirect emissions in the value chain | Business travel, purchased goods, freight, employee commuting, investments |
Choosing your approach
Before picking a tool, consider a few things. Are you working on this alone, or will multiple people contribute activity data across your organization? How often do you need these calculations: once a year for annual reporting, or more regularly as part of an ongoing process? What technical resources do you have available: a sustainability team comfortable in spreadsheets, or developers who can build and automate integrations? And what does your data look like — structured records you already manage, or unstructured inputs like invoices and spend reports?
Use the table below to match your situation to the right product.
| If you want to… | Reporting frequency | Technical skills | Use |
|---|---|---|---|
| Calculate without coding, using guided templates | Annual or one-off | No coding required | Bulk Calculators in Data Studio |
| Work in your existing spreadsheets | Annual or quarterly | Familiar with Excel or Google Sheets formulas | Excel Add-in / Google Sheets Extension |
| Automate, integrate into a product, or process at scale | Ongoing / high volume | API / coding required | Climatiq API with an integration into your analytics tools |
Note that Climatiq is not an out-of-the-box CCF solution. It is a highly flexible toolbox. It provides accurate, up-to-date emission factors and calculation options across all scopes, which organizations use as the calculation layer within their own workflows, reporting tools, and systems. Climatiq does not provide data visualization, aggregation dashboards, or report export — it gives you the tools to calculate accurately, and you build the reporting layer around it. Most implementations require some setup or customization to fit your data and processes.
Choose the tool that best fits your team and workflow:
No-code platform for sustainability teams. Use Bulk Calculators to upload activity data by emission category and receive CO2e results — no coding required.
Calculate scope emissions directly from spreadsheet data. Ideal for sustainability teams and consultants managing annual activity datasets in Excel.
The same no-code calculation capability in Google Sheets. Use Climatiq formulas to calculate and aggregate scope emissions across your activity data.
For teams building CCF tools or processing large volumes of data. Access all scope endpoints (estimate, energy, travel, freight, and procurement) via a single REST API.
Your journey
Define your reporting boundary
Decide which parts of your business to include in the footprint — which legal entities, locations, and operations are in scope, and which reporting year you are covering. If you need guidance on how to draw the boundary, the GHG Protocol recommends three approaches: equity share, financial control, or operational control. Note any activities or categories you are leaving out and the reason why.
Choose your Climatiq tool
Based on your team setup and workflow, select the tool you will use from the options above. Your choice affects how you will need to structure and format your activity data in the next step. For example, Data Studio’s Bulk Calculators use category-specific upload templates, while the API expects structured JSON payloads.
Collect and align your activity data
Gather fuel consumption records (Scope 1), energy bills and grid region (Scope 2), and Scope 3 inputs such as travel records, spend data by category, freight volumes, and supplier information. Align the data to the format and categories your chosen tool expects.
Calculate emissions by scope
Work through Scope 1, Scope 2, and your material Scope 3 categories using your chosen tool. For most organizations the most significant Scope 3 categories are 3.1 (purchased goods and services), 3.6 (business travel), 3.4/3.9 (freight), and 3.3 (upstream energy). See the supporting resources below for methodology guides for each.
Aggregate, validate, and report
Sum CO2e results across all scopes. Review for completeness and flag any significant data gaps or estimation uncertainties. Document your methodology, emission factors used, activity data sources, and any assumptions. This documentation is required for CSRD, CDP, and third-party assurance.
