A leading player in digital sustainability

An open-source, audited, multi-channel measurement methodology that integrates seamlessly into your ESG reporting.

Comprehensive measurement of your media and digital investments

A holistic measurement of your ecosystem based on the latest industry standards.

Our carbon measurement methodology aligns with industry standards.
  • Offline and digital media > Global Media Sustainability Framework v1.2.
  • Web eco-design > Afnor, RGESN, SWDM v4
  • Creative production > ISO 14067 and PAS 2050 standards.
  • Artificial Intelligence > Green Software Foundation Software Carbon Intensity (SCI) for AI, Ecologits
  • Cloud & Services > Green Software Foundation Software Carbon Intensity (SCI), Cloud Carbon Footprint

Measuring the carbon impact of our digital services: how does it work ?

The 3 main emission sources are data centers, transmission networks and user equipment.

In each case, our methodology accounts for 2 emission categories:

– Operational emissions: energy consumption across the full digital infrastructure

– Embodied emissions: emissions generated in the material extraction and manufacturing process of the infrastructure

How are your digital emissions calculated ?

Every digital activity consumes energy: data is stored on servers, transmitted over networks, and displayed on the user’s device. We measure this energy based on the volume of data transferred, then convert it into CO₂e according to the carbon intensity of electricity at each stage. The result: an accurate footprint of your digital activity.

CO2e emissions measurement

Advertising Campaign Measurement

  • Every ad impression consumes energy, which is converted into CO₂ based on the carbon intensity of the electricity where it is consumed.
  • Our measurement methodology enables an in-depth analysis of your emission sources by channel, campaign objective, format, creative assets, and more.
  • Our metrics allow you to track and manage the environmental efficiency of your campaigns over time.

Lifecycle of a media campaign

Sustainable Web Design

  • Every page view consumes energy (proportional to page weight, request count, and running scripts), which is converted into CO₂e based on the grid carbon intensity of both the hosting location and the user device.
  • Our measurement methodology enables a detailed analysis of your emission sources by page, template, asset type (media, third-party scripts), and user journey.
  • Our metrics allow you to guide the eco-design of your websites while improving user experience.

Optimizing for carbon efficiency speeds up page load time: a mere 0.1 second gain that can boost your conversion rate by 8%.

footsprint’s open-source, cross-channel measurement methodology is independently audited and aligned with major international standards and frameworks:

Offline & digital media: Global Media Sustainability Framework (GMSF v1.2), GHG Protocol, SRI, ADEME, Ad Net Zero, IAB Europe.

Web eco-design: AFNOR, RGESN, Sustainable Web Design Model (SWDM v4).

Creative production: ISO 14067 and PAS 2050.

Footsprint develops actionable performance indicators that can be directly used by media teams, such as:

– Carbon cost per click
– Carbon cost per conversion
– Carbon cost per 1,000 impressions
– Carbon cost per dollar/euro invested

This approach makes environmental impact an actionable media optimization criterion, helping teams improve campaign efficiency while reducing their carbon footprint.

Absolutely. Carbon data is available through our proprietary SaaS platform or can be directly integrated via API into your existing reporting solutions.

Web eco-design combines carbon footprint reduction with an improved user experience. Optimizing website efficiency can also improve page load times: a gain of just 0.1 seconds can increase conversion rates by up to 8%.

Our methodology assesses the energy consumed by digital activity, including data transferred, requests, scripts and file sizes and converts it into CO₂e based on the carbon intensity of electricity at each stage.

The methodology accounts for 3 sources of emissions across two categories:

Operational emissions: Energy consumption generated during the use of digital services.

Embodied emissions: Emissions associated with the extraction of raw materials and the manufacturing of infrastructure and end-user devices.
