Please note that data provided on this page include measurements and estimations collected from SeenThis Emissions Dashboard based on the below assumption. For details, read more here.

1. SeenThis measures data transfer for creative delivery, fetched from CDN centers. 2. Emissions from data transfer of creative delivery in CO₂ equivalents (CO₂e) in metric units, including SeenThis scope 1 (direct fuel emissions), scope 2 (market-based energy emissions), scope 3 upstream (co-working space emissions, hosting, data center and CDN direct and embodied emissions), and scope 3 downstream emissions (network and end-user device direct and embodied emissions). SeenThis applies the distribution part of the SRI & Alliance Digitale framework to assess the carbon footprint of downstream emissions for creative delivery, as well as server emissions for conventional technology. The framework considers the full life cycle of creative delivery from server to end-user device, but excludes other sources of emissions that might be relevant to a cradle-to-grave assessment of online advertising. gPM refers to g CO2e per 1,000 impressions. 3. The estimated avoided impact is based on a comparison to running creatives of corresponding quality using conventional technology (video codec h264 main, mp4, no larger than 4MB; or static jpeg or png, no larger than 50-350 kB depending on dimensions, no additional compression if asset is under 150kB; assuming full download for uncached impressions). The equivalent emissions of other activities are listed as either or, not collectively, assuming 131 g CO2e per passenger km, 10.5 g CO2e to fully charge a depleted smartphone battery for 2 hours, or 285 g CO2e per passenger km and 1,765 km.
