Is Netflix Bad for the Environment? How Streaming Video Contributes to Climate Change
Sending dozens of emails a day, making a quick call on WhatsApp, uploading some photos to the cloud, watching a short viral clip on YouTube: It's all part of the digital daily life around the world. For the individual, it may be "just one photo" or "just a few minutes of video," but, taken together, our collective internet traffic contributes enormously to climate change.
Everything a computer, tablet or smartphone does requires electricity. And, to generate that electricity, the world still predominantly uses fossil fuels — which produce carbon dioxide and contribute to heat-trapping greenhouse gases.
Digital technologies have even surpassed the aerospace industry in terms of carbon emissions. While aviation's share of global CO2 emissions is estimated to be around 2.5%, and rising, nearly 4% of all CO2 emissions can now be attributed to global data transfer and the necessary infrastructure, according to a recent study by Paris-based think tank The Shift Project. The NGO is researching ways to redesign the world's economy so that it runs on renewable energy.
"Limited Energy Resources"
The calculations include both the energy costs of creating IT infrastructure and the actual use of that infrastructure — with the latter consuming 10 percentage points more electricity than the production of all equipment and technology combined.
According to a projection by IT giant Cisco, by 2022 around 60% of the world's population will be online, with video making up more than 80 percent of all internet traffic. Maxime Efoui-Hess, an energy and environmental expert at The Shift Project and author of the study, said we need to urgently reconsider the future of internet use and think about cutting back.
"We have limited energy resources," he said, pointing out that even if we make the shift to renewables now, "the internet is a worldwide thing, so it would require every country in the world to be powered by renewable energy." But he said that goal remains impossible in such a short time, meaning we can't let internet usage grow as rapidly as it has to this point.
The largest share of that growth is now video traffic: 80% of all data transferred online is video data, with nearly 60% of that being online video, meaning streaming videos stored on a server and viewed remotely, via sites like Netflix, YouTube or Vimeo.
The problem: transferring videos online is data-intensive. In 2018, online video traffic was responsible for more than 300 million tons of CO2, equivalent to what a country the size of Spain releases in a year — for all sectors combined. The higher a video's resolution, the more data that's required. Ten hours of high-definition film consumes more bits and bytes than all the English-language articles in Wikipedia put together, according to The Shift Project.
The way we consume videos and movies has also changed radically. In the past, films told a story with moving pictures and music; today, online videos are primarily used to hook a person's attention for as long as possible. "It moves, and there's sound, and that's attractive to our brain," said Efoui-Hess. "But it can lead to addictive behavior."
Platforms like YouTube, Facebook and Netflix have increasingly exploited this biological preference, he said. The autoplay function lets videos start automatically, without sound and with subtitles, making information even easier to consume. "That's just the way to make you watch the whole video — and it works."
Last Mile is Crucial
Can this growing hunger for videos be satisfied, in a way that spares the climate? Or do we have to go without our favorite streaming TV series and films? Efoui-Hess points out that it would indeed be better to watch something on a standard TV broadcast — analogue broadcasting also consumes electricity, but the data is only transmitted over a limited geographical area, rather than halfway around the world, as is the case with streaming video.
Lutz Stobbe, who researches the environmental impact of information and telecommunications technology at the Fraunhofer Institute for Reliability and Microintegration in Berlin, said when it comes to data transfer, the last mile is crucial — as in, what specific technology is used to bring the data to the consumer.
Mobile data transfer uses the most electricity. Basic transmission loss, solid structures like buildings, vegetation and atmospheric conditions — in other words, weather — can weaken electromagnetic waves and led to buffering videos. For that reason, the transmission signal needs to be boosted, especially when the signal is being routed over long distances through old copper cables.
"The power amplifiers have a low electrical efficiency, which means that about half of the energy used for data transmission is lost as heat," said Stobbe. "The most efficient transmission technology is fiber-optic cables, which transmit signals by light."
Germans, for example, mainly surf the internet via copper cables; as of 2017, just over 2% of all broadband connections in the country used fiber-optic cables. By contrast, the mobile communication network is being expanded on a massive scale.
To help save on energy, Stobbe is currently working on something known as edge computing, in which the desired data is stored locally, closer to the consumer in places like data centers in major cities. That way, it doesn't have to travel as far to get to where it's going.
Stobbe said those hoping for next-generation devices and processes to be more energy-efficient will be disappointed. When it comes to technology, energy efficiency hasn't improved significantly in the last decade. That's why it's best to use your older devices as long as possible, he said.
What remains are small tweaks to our daily routine. "This is what's called digital hygiene," said Stobbe. "Do you really need to upload 25 images of the same thing to the cloud? Every photo, every video is constantly backed up, for safety reasons, and that consumes energy every time. If instead you delete a few things here and there, you can save energy."
Efoui-Hess is also an advocate of small changes. "Use Wi-Fi, not mobile networks, watch on the smallest screen you can — and high-definition video on a smartphone aren't really necessary," he said, pointing out that watching high-definition videos on a smartphone over a mobile network uses the most electricity, and consequently is the worst for the climate.
To raise awareness of the impact everyday digital life has on the climate, The Shift Project has developed a CO2 calculator browser add-on that measures the emissions generated by internet activity. Nevertheless, the NGO doesn't place the responsibility solely on the end user; it believes the issue should be an important part of the political agenda. But so far, neither governments nor international institutions have recognized the problem, let alone made any efforts to bring about change.

As we reach the official end of hurricane season, 2020 will be one for the record books. Looking back at these long, surprising, sometimes downright crazy past six months (seven if you count when the first named storms actually started forming), there are many noteworthy statistics and patterns that drive home the significance of this hurricane season, and the ways climate change may have contributed to it.

An unprecedented climate lawsuit brought by six Portuguese youths is to be fast-tracked at Europe's highest court, it was announced today.
The European Court of Human Rights said the case, which accuses 33 European nations of violating the applicants' right to life by disregarding the climate emergency, would be granted priority status due to the "importance and urgency of the issues raised."
‘Protect Our Future’<p>Cláudia Agostinho (21), Catarina Mota (20), Martim Agostinho (17), Sofia Oliveira (15), André Oliveira (12) and Mariana Agostinho (8) are <a href="https://www.desmogblog.com/2020/09/03/youth-climate-lawsuit-portugal-33-european-countries" target="_blank">bringing the case</a> with nonprofit law firm Global Legal Action Network (<span style="background-color: initial;">GLAN</span>), arguing that none of the countries have sufficiently ambitious targets to cut their emissions.</p><p>Portugal recently sweltered through its <a href="https://www.ipma.pt/pt/media/noticias/news.detail.jsp?f=/pt/media/noticias/textos/resumo-clima-julho-20.html" target="_blank">hottest July in 90 years</a> and has seen a rise in devastating heatwaves and wildfires over recent years due to rising temperatures. Four of the applicants live in Leiria, one of the regions worst-hit by the forest fires that killed more than 120 people in 2017. </p><p>Responding to the development, André Oliveira, 12, said: "It gives me lots of hope to know that the judges in the European Court of Human Rights recognise the urgency of our case." </p><p>"But what I'd like the most would be for European governments to immediately do what the scientists say is necessary to protect our future. Until they do this, we will keep on fighting with more determination than ever."</p>
‘Highly Significant'<p>The decision represents a "highly significant" step, <a href="https://www.glanlaw.org/about-us" target="_blank">GLAN</a> Director Dr. Gearóid Ó Cuinn said in a <a href="https://youth4climatejustice.org/" target="_blank">press release</a>.</p><p>"This is an appropriate response from the Court given the scale and imminence of the threat these young people face from the climate emergency," he added. </p><p>By suing the 33 countries all together, the youths aim to compel these national governments to act more aggressively on climate through a single court order, which would potentially be more effective than pursuing separate lawsuits or lobbying policymakers in each country.</p><p>If successful, the defendant countries would be legally bound not only to ramp up emissions cuts, but also to tackle overseas contributions to climate change including those of their multinational enterprises.</p>
‘Major Hurdle’<p>The <a href="https://youth4climatejustice.org/the-case/" target="_blank" rel="noopener noreferrer">countries targeted</a> include all of the European Union member states as well as Norway, Russia, Switzerland, Turkey, Ukraine and the United Kingdom, none of which are currently aligned with <a href="https://www.ecowatch.com/tag/paris-agreement">Paris agreement</a> target to limit global temperature rise to well below 2 degrees C (3.6 degrees F) and pursue a limit of 1.5 degrees C (2.7 degrees F).<a href="https://climateactiontracker.org/countries/" target="_blank" rel="noopener noreferrer"> </a></p><p><a href="https://climateactiontracker.org/countries/" target="_blank" rel="noopener noreferrer">Climate Action Tracker rates</a> most of Europe as "insufficient" in terms of its emissions reduction policies based on the Paris target, while Ukraine, Turkey and Russia are assessed as "critically insufficient" – meaning they are on track for a warming of 4 degrees C or higher.</p><p>The European Union has pledged to slash its emissions by <a href="https://ec.europa.eu/clima/policies/eu-climate-action/2030_ctp_en" target="_blank" rel="noopener noreferrer">at least 55 percent by 2030</a>.
