Total estimated carbon footprint
0 kgCOâ‚‚e / year
Indicative ball-park estimate based on the DPC Carbon Footprint Calculation Tool v1.0. Record sources, assumptions, and confidence levels to document the quality of every input.
Breakdown
Relative contribution of each category to the total carbon footprint.
Summary by preservation activity
On-premise and networking emissions are mapped to DPC preservation activities.
| Preservation activity | On premise | Networking | Total |
|---|---|---|---|
| Total | 0 | 0 | 0 |
General information
Calculation identity and reporting-period basis.
DPC v1.0 parity. Networking uses the
365/12 factor exactly as implemented in the official v1.0 workbook. Website visits and downloads are annual inputs.On-premise data centres & servers
Enter server/storage data and review automatically calculated results. Scroll the table horizontally when needed.
| Function | Machine | Country | Make / model | Idle W | Max W | Util. % | Server W | Storage TB | Mean storage (Wh/TBh) | Storage W | PUE | Energy kWh/yr | Grid kgCOâ‚‚e/kWh | Carbon kgCOâ‚‚e | Source | Confidence | Notes |

How are these figures calculated?
Server power = Idle + (Max − Idle) × UtilisationStorage power = Storage capacity × Storage intensityEnergy = (Server + Storage) × 24 × 365 ÷ 1000 × PUECarbon = Energy × Grid factorServices provided in the cloud
DPC v1.0 provides exactly two cloud inputs: Data Centres/Servers and Networking. Enter the annual kgCOâ‚‚e figure reported or estimated for each service.
| Use | Description | Value (kgCOâ‚‚e/year) | Source | Data Confidence | Notes |
|---|
Cloud providers may bundle embodied carbon into their figures. Record the source, confidence, and any relevant assumptions or limitations in Notes, as in the v1.0 workbook.
Networking
Transmitted + received data are converted to GB, energy use, and emissions.
| Function | Machine | TX MB/day | RX MB/day | kWh/GB | Grid kgCOâ‚‚e/kWh | Data GB | Energy kWh | Carbon kgCOâ‚‚e | Source | Confidence | Notes |

Website Use
Estimate page and download data transfer for website use.
Travel
Enter travel emissions from an external calculator. Use either tCOâ‚‚e or kgCOâ‚‚e for each journey.
| Date of travel | Description (journey - from - to) | Mode of transport | tCOâ‚‚e | kgCOâ‚‚e | Source | Notes |
|---|
If you enter tCOâ‚‚e, the calculator converts it to kgCOâ‚‚e by multiplying by 1,000. If your source already provides kgCOâ‚‚e, enter that value directly instead.
Grid Factors
Reference factors copied from the DPC v1.0 workbook. On Premise rows automatically use a matching country factor; the field remains editable for countries or factors you add yourself.
| Country | Raw value | Units | Converted kgCOâ‚‚e/kWh | Source | Link |
|---|
Cloud Factors
Reference proxy data copied from the DPC v1.0 workbook for AWS, Google Cloud Platform, and Microsoft Azure.
AWS Data Centres
| AWS Region | Country | NERC Region | Emissions factor (tCOâ‚‚e/kWh) | Emissions source |
|---|
Google Cloud Platform
| Google Cloud Region | Location | CFE (%) | Grid carbon intensity (gCOâ‚‚eq/kWh) | Grid carbon intensity (tCOâ‚‚e/kWh) |
|---|
Microsoft Azure
| MS Azure Region | Location | NERC Region | Emissions factor (tCOâ‚‚e/kWh) | Emissions source |

Methodology & provenance
Principles for using the calculator while preserving research-data traceability.
Use actual data when available
Prioritise measured data or provider reports before using estimates or proxies.
Record the source
Source, Confidence, and Notes fields are provided for each major component.
Match the v1.0 workbook
Networking preserves the official workbook formula, including its 365/12 factor.
Interpret results as estimates
Results are ball-park estimates, not formal emissions reporting or a GHG audit.
