Reducing website carbon emissions by blocking ads

Blocking advertising on the web is not only good for increasing the speed and privacy of your own web browsing, but also good for the planet.

What is the environmental impact of visiting the homepage of a media site? What part do advertising, and analytics, play when it comes to the carbon footprint? We tried to answer these questions using GreenFrame, a solution we developed to measure the footprint of our own developments.

The results are insightful: up to 70% of the electricity consumption (and therefore carbon emissions) caused by visiting a French media site is triggered by advertisements and stats. Therefore, using an ad blocker even becomes an ecological gesture.


Overall we observe the same thing: the carbon footprint of a website decreases if there are no ads or trackers on the website. The difference is significant: Between 32% and 70% of the energy consumed by the browser and the network is due to monetization.

The websites analyzed generate between 70 and 130 million visits per month, and their work has therefore a real impact on the environment.

Reducing the consumption of one of these sites by only 10% (20mWh), per visit for a site with 100 million monthly visitors is equivalent to saving 24,000 kWh per year.

Naming heatwaves

I’m hoping other countries follow suit and bring some attention to heatwaves as human-caused extreme weather events.

The world’s first named heat wave hit Seville, Spain, this week, pushing temperatures past 110 degrees Fahrenheit and earning the most severe tier in the city’s new heat wave ranking system.

Heat wave “Zoe” has brought scorching temperatures to the southern part of the country for the last few days, particularly the region of Andalusia where Seville is located. Even in the evenings, the Spanish meteorological service recorded temperatures that hovered in the mid-80s in some areas — an extra stress on the human body, which relies on cooler nights to recover from high daytime heat.

Foregrounding externalities

I found this article via the excellent Sentiers, which I support as a member. It discusses the importance of making visible externalities — a term which is reasonably common in literature relating to economics and risk, but not general discourse.

An externality is “an indirect cost or benefit to an uninvolved third party that arises as an effect of another party’s (or parties’) activity”. In this case we’re talking about the cost of extracting materials from the ground and shipping them around the world.

The shipping container led to the highly sophisticated supply chains we see today, which has been extremely efficient in making, exploiting and creating a form of global labour and material arbitrage.

It is vital to the relocating and offshoring of production to places where the costs are far lower. But even more importantly it makes the consequences, or ‘externalities’, of production completely invisible to Western consumers.

What if we suddenly decided that we’re going to stop pretending those things don’t happen? What if we embrace the consequences of what it means to manufacture products and to build, and to price its full cost? If the sticker price included the full cost of everything we build, then suddenly making things locally and sourcing materials locally would become much more attractive.
