A digital carbon footprint represents the total amount of carbon dioxide equivalent (CO2e) attributable to the lifetime manufacture, use and end-of-life of the digital products and services we use.
This includes the products we buy, such as laptops and mobile phones, and also the services we consume, including streaming video services and online shopping.
Our digital carbon footprints extend across internet connected devices, but also to other devices and services that enable our digital lifestyles, e.g. TVs, computer monitors, asset tracking tags and peripheral USB cables.
The lifetime CO2e of a product or service is typically split into two high-level categories; embodied emissions and operational emissions.
- Embodied emissions are those that are generated in the manufacture, storage and shipping of the items.
- Operational emissions are those generated in the lifetime use of the product or service.
The split between the two is typically 80% embodied, 20% operational as highlighted in a couple of quote in the slide below…
