You search on Google once and you may have unexpected CO2 emissions

Eating, sleeping, entertainment …… Every day we live in the world, we are all contributing the same thing to this earth —carbon emissions.

Just as the more obvious industrial production, vehicle exhaust, etc., the high-frequency behavior that we are doing every day, has hardly caught our attention. Its effect seems too weak.


An environmental artist named Joana Moll does not seem to think so. According to her many years of research and observation, Google, one of the most influential websites in the world, has become the main global carbon emission that can compete with countries like America, China and India.

to this end,Moore specifically set up a project called CO2GLEIs used to provide a more direct visualization of the carbon dioxide emissions that people use when using Google.

When we click thisWeb pageAt the time, only one line of text was displayed on a white background: Google has already emitted XX kilograms of carbon dioxide when you open this page. Among them, "XX" is a real-time rolling number that represents the ever-increasing carbon emissions.


Maybe it's because it's not intuitive enough to show numbers. Moore also didAnother page. On top of that, the amount of CO2 emitted by Google's search operations every second is equal to the number of rows of trees; rather, how many trees are needed to offset the CO2 emitted by these operations.


The industry once had such a calculationEach transfer of 1GB of data consumes almost 13 kilowatt hours of electricity, which is equivalent to 707 kilograms of carbon dioxide emissions.

So Moore's estimate, given that Google's webpage capacity is about 2MB, it handles nearly 47,000 visit requests per second, which means that Google pages generate almost 500 kilograms of CO2 emissions every second.


In 2009, GoogleHas been announcedThe amount of carbon dioxide emitted per one search operation is 0.2 g; however, in the statistics of the carbon footprint of environmental research institutes, this figure is between 1 kg and 10 kg.

A Google spokesperson afterRepresented in replyMoore's calculation method is not accurate, she may just be to raise everyone's attention to the network carbon emissions. In fact, the CO2 emissions generated by each user using all of Google’s services within a month is about the same as the one mile they drive.


However, such comparisons cannot erase the "contribution" of these Internet services to global carbon emissions. Just like Google, technology giants such as Apple, Amazon, and Facebook are all major players in generating carbon emissions. Even if they don't have as much traditional emissions equipment as other industries, the facilities that support them for daily operations still generate large amounts of carbon dioxide.


according tostatisticsThe carbon emissions generated by Facebook in 2016 are almost equivalent to the emissions of 77.5 million households in the United States.

This has indeed become a hidden problem that cannot be ignored. When we enjoy convenient and efficient Internet services, we also need to pay attention to the negative effects they bring.

Today, more and more Internet companies are realizing this problem. Both Google and Apple mentioned earlier have given plans to continuously reduce the company’s carbon emissions; they claim to convert all their offices, retail stores, and data centers worldwide to use 100% renewable energy. .
