After EU officials called on the public to give up “HD” in March, British media BBC also rushed to call for more than half a year, but this time it was not domestic isolation that “crushed” the network. Not because the British government “blocked” Huawei. After 5G, the speed of the network is worrying, but to “reduce carbon emissions”. It seems clear and sincere, and the price of “environmental protection” is higher.

On December 3 local time, the BBC (British Broadcasting Corporation) published an article “Abandon High Definition and New Technologies to Address Climate Change”, citing a report by a Royal Society scientist saying that looking at “definition standard “(clear standard) Grade) The video can” slightly reduce carbon emissions “.
According to the report, “HD” mode of mobile video generates 8 times more carbon emissions than “SD” mode. Media streaming platforms and regulators should take steps to set the default definition of video playback to “SD.” .
According to the report, carbon emissions generated by digital technology represent 1.4% to 5.9% of total global emissions. If people are not looking at the screen while listening to music, they should turn off all videos. Such a small change can save around 5% of the carbon emissions of the media streaming platform.
Furthermore, the report also noted that if people can change the habit of changing their mobile phones every two years to once every four years, carbon emissions can also be greatly reduced. Because the carbon emissions in the production process represent half of the total emissions during all the use of electronic products (calculated in 2 years).
In light of this, the report asks people to buy more second-hand equipment and use cloud technology to store files.
but,The BBC admits that some of the data in the report is controversial.
At the end of the article, the BBC mentioned that the other author of the research report, Professor Corinne Le Querre from the University of East Anglia, admitted “To be honest, digital technology is only a small part of your carbon footprint compared to flying once a year.. Of course, hoarding less makes more sense. “
It is worth mentioning that the BBC reported in May this year thatDuring the period of COVID-19 home isolation, the average broadband speed in the UK dropped by 2%，Among them, Virgin Media, a local provider in the UK, fell 10%But the British Communications Office still feels that the broadband system is “holding up well”.
On the London Underground, which is basically covered by Virgin, Londoners who are disappointed in the speed of the internet generally choose to stay in a daze or read the newspaper.
Furthermore, according to a survey published by the British “Independent” in August this year, in 12 countries and regions, including Europe, America and Asia (excluding mainland China),The UK has the worst internet speed and the most unstable connection。
Compared to Saudi Arabia, number one on the list, 5G speed in the UK is more than 4 times slower. In terms of cooperation with China’s Huawei on 5G technology, the two countries are also worlds apart.
Here, Saudi Arabia has maintained close cooperation with Huawei to accelerate the realization of 100% national broadband coverage; There, the British government with the slowest internet speed also announced that “US sanctions raise security concerns”: after September 2021, the UK will be banned. Wireless operators install Huawei equipment on their high-speed 5G networks.
It is not an entrepreneur, but it also squeezes other high-tech countries that are conducive to people. The UK, which values the protection of the environment, has chosen “energy saving and emission reduction” in the name of asking the public to abandon technological expertise and return to the “standard definition”.
