The NegaOctet database is composed of more than 500 data classified according to five levels of granularity:
- Level 0 - Basic data (including wafer)
- Level 1 - Digital components
- Level 2 - Equipment
- Level 3 - Systems
- Level 4 - Digital services
Each data is composed of an asset for manufacturing, distribution, use and end of life, for a total of 1,600 life cycle inventories (LCI). The database comes with:
- Configurators to dynamically assess the environmental impact of some equipment (excluding use phase)
- Good practice sheets to facilitate the use of data
The NegaOctet database is currently available in the EIME software or in Excel format.
Negaoctet research work has made it possible to:
- To have homogeneous multi-criteria data to assess the environmental impact of a digital service
- To carry out data consolidation and development work at all levels of the digital industry: components, equipment, networks, data centers
- To carry out the evaluations on all the PEF criteria and to carry out the standardization and weighting of the indicators to present the interest of the multi-criteria
- Evaluate the MIPS indicator (resource consumption indicator)
Wafer & Digital components
Our components have a high level of precision. The production of silicon wafers is at the heart of the impacts of semiconductors taking into account the following level of parameterization:
- Die surface
- Number of masks
- Engraving level
The impacts of LCD and OLED screens take into account the CSR reports of major manufacturers.
Ready-to-use equipment is available, such as: computers, tablets, smartphones, TV boxes, etc. as well as connected objects (sensors, thermostats, connected speakers, etc.).
Configurable models have been created to study the environmental impact of IT equipment according to the technical characteristics that have the most influence, namely:
- Storage capacity
The NegaOctet database includes a first set of data on the environmental impact of fixed and mobile networks covering:
- The access network
- The aggregation network
- The backbone
The geographical coverages studied are France and Europe.
Data center modeling is based on:
- Approach combining PUE and integration of the impacts associated with the building and the equipment of the technical environment.
- Configuration of servers and technical equipment according to technical criteria: CPU, RAM, storage, load rate.

Evaluate your digital services with EIME software
Base Impacts® version
From the NegaOctet project, 55 data were developed specifically for the Base Empreinte® (open access). This data covers different levels of a digital service:
- Digital services: Email Sending, Video Streaming, File Transfer, Cloud Data Storage, Web Conferencing, Web Query
- Terminal equipment: Desktop and laptop computer, tablet, smartphone, computer screen, television, external hard drive, external SSD, USB key, internet box, connected watch, connected thermostat, industry sensor
- Fixed and mobile network: impact of transporting 1 GB
- Datacenter equipment: impact of server and virtual machines
These data are compatible with ADEME's product category rules (PCR). More information on MinumEco.
