Do you have any questions?

We support the measurement and reduction of the carbon footprint of your entire offline and digital marketing ecosystem: media campaigns (Search, Social, Display, Programmatic, TV, Outdoor), influencer marketing, eco-design of e-commerce websites, mobile applications, email marketing, AI, and training for your teams...
Our methodology takes into account the entire advertising distribution chain: volume of impressions, creative formats, platforms used, content storage consumption in data centers, data transfers, distribution networks, and the energy consumption of users' devices. We thus analyze the actual emissions generated by each campaign.
We assess emissions related to hosting, data storage, network transfers, displayed content (images, videos, scripts), and the energy consumption of devices used to access the site. This approach helps identify key areas for optimization.
Yes. Our results are designed to support your carbon reduction trajectories, ESG indicators, and extra-financial reporting processes. Our methodology is based on recognized standards and provides transparent, auditable, and actionable data for sustainability teams.
