Jakarta, CNBC Indonesia – Are you the type of person who is shy to open the camera during the Zoom Meeting? Calm down, it turns out that your nature can help save the Earth. Because according to a study, turning off video calls can reduce gas emissions.
Research from Yale University, Purdue and MIT states that this step can reduce carbon footprint by up to 96% and gas emissions by up to 86%, quoted by IFL Science, Tuesday (19/1/2021).
Researchers say that the pandemic that forces activities to online has indeed reduced carbon emissions in terms of travel. But it turns out that the increasing use of the internet also has environmental impacts.
For information, before a number of countries did lockdown (lockdown) the carbon footprint for the internet has increased to around 3.7% of greenhouse gas emissions. Meanwhile data center electricity usage is 1% of global energy use.
Meanwhile, since March last year, internet usage in a number of countries increased by 20%. If the trend continues, it is assumed to fill 300 thousand Olympic swimming pools, covering an area in Los Angeles and requiring 115,229 square kilometers of forest to sequester carbon.
In its report, Zoom was ranked second in the maximum carbon footprint after Netflix. Apart from these two services, there are Tiktok, WhatsApp and Facebook which also emit high carbon gas from their use.
Researchers also have a powerful way to save the planet by adjusting their use of these services.
For example, when Zoom Meeting is to turn off the camera. The report suggests that if 1 million users did this it would reduce 9,023 tonnes of carbon emissions.
Meanwhile, streaming service users can change the image quality. The research team said 70 users changing from HD to SD would reduce 2.5 million tons per month.
“Small activities such as turning off video during virtual meetings, reducing the image quality of streaming services, lowering gaming time, limiting social media time, deleting email and non-essential content on cloud services or canceling subscriptions from email lists can significantly reduce the carbon footprint of usage. the internet, “said the research team.
