Carbon footprint

What is a carbon footprint?

A carbon footprint is the total amount of greenhouse gases produced by an activity, product, person, or organisation, expressed as carbon dioxide equivalent (CO2e). It bundles different gases into one comparable number, so a flight, a factory, and a website can be measured on the same scale.

Footprints are usually split into three scopes. Scope 1 covers direct emissions, like a company's own vehicles. Scope 2 covers the energy a company buys, mainly electricity. Scope 3 covers everything else in the value chain, from suppliers to the way customers use a product, and it is usually the largest and hardest to measure. Digital products carry a real footprint too: every page load runs servers, networks, and devices that draw power. A single high-traffic website can emit more carbon over a year than several long-haul flights.

Measuring a footprint is the first step toward reducing it. Once the sources are clear, an organisation can cut emissions, switch to cleaner energy, and offset what remains. The credibility of any net zero or carbon neutral claim rests on how honestly the footprint behind it was counted.

Carbon footprint at Dallonses

As a certified B-corp, we account for our own footprint and treat the carbon cost of what we build as part of the work, not an afterthought. Software has emissions. Heavy pages, wasteful infrastructure, and over-provisioned servers all burn energy that someone pays for in carbon.

Our sustainable technology consulting helps clients measure and lower the footprint of their digital products: leaner code, efficient hosting, and architectures that scale down as well as up. Green hosting and right-sized infrastructure cut emissions and cost at the same time, so the business case and the climate case point the same direction. We would rather show a client a smaller real number than sell them a bigger offset.

Want to know the carbon cost of your digital product, and how to bring it down? Let's measure it.
