Electronic waste has grown to record levels. Here’s why that’s a huge problem

The numbers are staggering. In 2022, the world generated 62 million metric tons of electronic waste, also known as “e-waste,” according to the United Nations Global E-waste Monitor released Wednesday.

Often, water systems are used to cool the equipment and keep it functioning. Water transports the heat generated in the data centers into cooling towers to help it escape the building, similar to how the human body uses sweat to keep cool, according to Shaolei Ren, an associate professor at UC Riverside.



After a lengthy court battle, the Oregonian newspaper forced Google to disclose how much its data centers were using in The Dalles, about 80 miles east of Portland; it turned out to be nearly a quarter of all the water available in the town, the documents revealed.

In July, Google released its most recent environmental report, showing its carbon emission footprint rose by 48 percent, largely due to AI and data centers. It also replenished only 18 percent of the water it consumed — a far cry from the 120 percent it has set as a goal by 2030. “Google has a long-standing commitment to sustainability, guided by our ambitious goals—which includes achieving net-zero emissions by 2030,” said Mara Harris, a spokesperson for Google.

Measuring the impact of digital solutions on the climate

 https://digital-strategy.ec.europa.eu/en/news/measuring-impact-digital-solutions-climate 


The European Green Digital Coalition has published new methodologies to measure the net impact of digital solutions on the climate.

The publications consist of 3 documents:

  1. Net Carbon Impact Assessment Methodology for ICT Solutions, including sector specific methodologies
  2. Real Life Case Studies
  3. Deployment Guidelines

The Net Carbon Impact Assessment Methodology for ICT Solutions lies at the core of the EGDC publications. It contains requirements for comparing scenarios with and without ICT solutions in a given context, allowing us to accurately quantify the positive contribution and direct footprint – in CO2 equivalent  of a specific digital solution.

It is complemented by sector-specific methodologies illustrating the practical application of each requirement for 6 sectors: energy, construction/buildings, smart cities, agriculture, transport and manufacturing.

The real-life case studies in all 6 sectors helped to refine and illustrate the impact of the methodologies. They were collected from EGDC members and stakeholders deploying ICT solutions. These include cloud-based tools for the energy management in buildings, 5G-enabled manufacturing and agriculture, smart energy and smart city platforms, and more.

Finally, the deployment guidelines were drawn up to enhance the understanding of the deployment of ICT solutions in different sectors. They include guidance on optimising their positive impact on the climate, and minimising negative consequences.

The European Commission proposed a Green Deal Industrial Plan to support its goal of achieving climate-neutrality by 2050 while enhancing the competitiveness of Europe’s net-zero industry.

A key pillar of the plan is ensuring the EU has access to technology, products and solutions that are key to transitioning to net-zero. These include photovoltaic cells, wind turbines, batteries, hydrogen electrolysers, carbon capture, storage equipment and more. Such products and solutions also represent a major source of economic growth and quality jobs in Europe.

Now to meet its goals, the software giant will have to make serious progress very quickly in gaining access to green steel and concrete and less carbon-intensive chips

Technical difficulties

When Microsoft Corp. pledged four years ago to remove more carbon than it emits by the end of the decade, it was one of the most ambitious and comprehensive plans to tackle climate change. Now the software giant's relentless push to be the global leader in artificial intelligence is putting that goal in peril.

The Seattle-based company’s total planet-warming impact is about 30% higher today than it was in 2020, according to the latest sustainability report published Wednesday. That makes getting to below zero by 2030 even harder than it was when it announced its carbon-negative goal.

Now to meet its goals, the software giant will have to make serious progress very quickly in gaining access to green steel and concrete and less carbon-intensive chips, said Brad Smith, president of Microsoft, in an exclusive interview with Bloomberg Green. “In 2020, we unveiled what we called our carbon moonshot. That was before the explosion in artificial intelligence,” he said. “So in many ways the moon is five times as far away as it was in 2020, if you just think of our own forecast for the expansion of AI and its electrical needs.”

Microsoft’s predicament is one of the first concrete examples of how the pursuit of AI is colliding with efforts to cut emissions. Choosing to capitalize on its early lead in the new market for generative AI has made Microsoft the most valuable company in the world, but its leaders also acknowledge keeping up with demand will mean investing more heavily in polluting assets.

AI products are power hungry and data-processing heavy. That first increases the workload of existing centers, which increases energy use. But such is the demand that, to keep up, Microsoft has to also build new data centers. That requires carbon-intensive cement, steel and microchips.

The tech giant plans to spend more than $50 billion between July 2023 and June of this year on expanding its data centers to meet rising demand for AI products. That number for the next 12 months, starting in July, is expected to be even higher, Chief Financial Officer Amy Hood said in an interview last month. Since February, the company has touted new data center projects in Wisconsin, Thailand, Indonesia, Spain, Germany and Japan.

Smith believes the good AI can do for the world will outweigh its environmental impact. “We fundamentally believe that the answer is not to slow down the expansion of AI but to speed up the work needed to make it more environmentally friendly,” said Smith. “I guarantee there’s one way to fail: It’s to give up.”

Small but growing

1.5%
Data centers around the world currently comprise about this share of global electricity use, according to the International Energy Agency. But this may go up as AI requires more energy than other forms of computing.

AI is responsible for a massive and growing amount of planet-warming carbon emissions, but just how much is hard for some researchers to tally.

Attempts to improve resilience to extreme heat across India have often been equally ill-conceived, despite a death toll estimated at more than 24,000 since 1992. Inconsistent or incomplete planning, a lack of funding, and the failure to make timely preparations to shield a population of 1.4 billion are leaving communities vulnerable as periods of extreme temperatures become more frequent, longer in duration and affect a wider sweep of the country.

In Kolkata, one of the most vulnerable cities in the world to temperature extremes, local officials are now examining potential solutions to combat urban heat —  from the addition of more trees to the use of porous concrete.

Yet, heat is rising fast. Several regions across India will see as many as 11 heat wave days this month compared to 3 in a typical year, while maximum temperatures in recent weeks have already touched 47.2C in the nation’s east, according to the India Meteorological Department. Those extremes come amid a national election during which high temperatures are being cited as among factors for lower voter turnout.

Our brains are feeling the heat. Conditions like dementia, epilepsy and depression could spread and worsen in severity as the world heats up, according to new research. 

The race for climate solutions continues. The Biden administration is seeking to bolster US solar manufacturers with a suite of policies that it says will help foster a deeper domestic supply chain for panels.

After 14 years as a member of Parliament for the UK’s Conservative Party, Chris Skidmore quit the government in January — an act of protest over Prime Minister Rishi Sunak’s decision to allow new oil and gas licenses. Skidmore says the party has lost its way on climate issues, costing the UK jobs, human lives and opportunities for growth. On this week’s Zero, Skidmore talks about how he tackled climate risks while in office, and why a vote for Conservatives no longer makes sense for anyone who cares about the environment.
