Carbon footprint

Business & organization calculator

A screening-level greenhouse-gas inventory organized by the GHG Protocol: direct emissions (Scope 1), purchased energy (Scope 2) and selected value-chain categories (Scope 3).

Organization and reporting boundary

Choose the period and which operations you include. Enter data only for operations inside the boundary you choose, and use the same boundary every year.

Organization name (optional, appears only on your printout)

Reporting year

Consolidation approach

Most small and mid-sized organizations use operational control. Under equity share, enter only your share of each operation’s activity.

Size metrics for intensity (optional)

Value chain (Scope 3)

The GHG Protocol defines 15 Scope 3 categories. For each, say whether you will assess it, whether it is not relevant to your organization, or leave it as not assessed. Results always show all 15 so gaps stay visible.

1. Purchased goods and services

No calculation method in this version (these usually need spend-based or supplier data); it will be shown as not assessed.

2. Capital goods

No calculation method in this version (these usually need spend-based or supplier data); it will be shown as not assessed.

3. Fuel- and energy-related activities

4. Upstream transportation and distribution

5. Waste generated in operations

6. Business travel

7. Employee commuting

8. Upstream leased assets
