California signed an agreement with major airlines to increase the use of sustainable aviation fuels, aiming to reach 200 million gallons by 2035 or about 40% of the state's air travel demand. The Hill reports: The California Air Resources Board (CARB) and Airlines for America (A4A) -- an industry trade group representing almost a dozen airlines -- pledged to increase the availability of sustainable aviation fuels statewide. Sustainable aviation fuels -- lower-carbon alternatives to petroleum-based jet fuels -- are typically made from nonpetroleum feedstocks, such as biomass or waste. At a San Francisco International Airport ceremony Wednesday, the partners committed (PDF) to using 200 million gallons of such fuels by 2035 -- an amount estimated to meet about 40 percent of travel demand within the state at that point, according to CARB. That quantity also represents a more than tenfold increase from current usage levels of these fuels, the agency added.

Among A4A member airlines are Alaska Airlines, American Airlines, Atlas Air Worldwide, Delta Air Lines, FedEx, Hawaiian Airlines, JetBlue Airways, Southwest Airlines, United Airlines and UPS, while Air Canada is an associate member. To achieve the 2035 goals, CARB and A4A said they plan to work together to identify, assess and prioritize necessary policy measures, such as incentivizing relevant investments and streamlining the permitting processes. A Sustainable Aviation Fuel Working Group, which will include government and industry stakeholders, will meet annually to both discuss progress and address barriers toward meeting these goals, the partners added. A public website will display updated information about the availability and use of conventional and sustainable fuels across California, while also providing details about state policies, according to the agreement.

An anonymous reader quotes a report from Ars Technica: More than 500 Amazon workers reportedly signed a letter to Amazon Web Services' (AWS) CEO this week, sharing their outrage over Amazon's upcoming return-to-office (RTO) policy that will force workers into offices five days per week. In September, Amazon announced that starting in 2025, workers will no longer be allowed to work remotely twice a week. At the time, Amazon CEO Andy Jassy said the move would make it easier for workers "to learn, model, practice, and strengthen our culture." Reuters reported today that it viewed a letter from a swath of workers sent to AWS chief Matt Garman on Wednesday regarding claims he reportedly made during an all-hands meeting this month. Garman reportedly told attendees that 9 out of 10 employees he spoke with support the five-day in-office work policy. The letter called the statements "inconsistent with the experiences of many employees" and "misrepresenting the realities of working at Amazon," Reuters reported. "We were appalled to hear the non-data-driven explanation you gave for Amazon imposing a five-day in-office mandate,'" the letter reportedly stated. [...]

In the letter, hundreds of Amazon workers reportedly lamented what they believe was a lack of third-party data shared in making the RTO policy. It said that Garman's statements "break the trust of your employees who have not only personal experience that shows the benefits of remote work but have seen the extensive data which supports that experience." The letter included stories from 12 anonymous employees about medical, familial, and other challenges that the new RTO policy could create. The letter also reportedly pointed out the obstacles that a five-day in-office work policy has on groups of protected workers, like those providing childcare. The new policy will not align with Amazon's "'Strive to be Earth's Best Employer' leadership principle,'" the letter said. In a statement, an Amazon spokesperson told Reuters that Amazon's benefits include commuter benefits, elder care, and subsidized parking fees.

An anonymous reader quotes a report from Behind the Black: According to a new very detailed engineering analysis into the causes of the collapse of the Arecibo radio telescope in Puerto Rico in 2020, the failure was caused first by a surprising interaction between the radio electronics of Arecibo and the traditional methods used to anchor the cables, and second by a failure of inspections to spot the problem as it became obvious.

The surprising engineering discovery is illustrated [here (PNG)]. The main antenna of Arecibo was suspended above the bowl below by three main cables. The figure shows the basic design of the system used to anchor the cable ends to their sockets. The end of the cable bunches would be inserted into the socket, spread apart, and then zinc would be poured in to fill the gap and then act as a plug and glue to hold the cables in place. According to the report, this system has been used for decades in many applications very successfully.

What the report found however was at Arecibo over time the cable bunch and zinc plug slowly began to pull out of the socket, what the report labels as "zinc creep." This was noted by inspectors, but dismissed as a concern because they still believed the engineering margins were still high enough to prevent failure at this point. In fact, this is exactly where the structure failed in 2020, with the first cable separating as shown in August 2020. The second cable did so in a similar manner in November 2020.

The report concluded that the "only hypothesis the committee could develop that provides a plausible but unprovable answer to all these questions and the observed socket failure pattern is that the socket zinc creep was unexpectedly accelerated in the Arecibo Telescope's uniquely powerful electromagnetic radiation environment. The Arecibo Telescope cables were suspended across the beam of 'the most powerful radio transmitter on Earth.'"

Heat-related deaths, food insecurity and the spread of infectious diseases caused by the climate crisis have reached record levels, according to a landmark report. The Guardian: The Lancet Countdown's ninth report on health and the climate breakdown reveals that people across the world face unprecedented threats to their health from the rapidly changing climate. "This year's stocktake of the imminent health threats of climate inaction reveals the most concerning findings yet," warned Dr Marina Romanello, executive director of the Lancet Countdown at University College London.

"Once again, last year broke climate change records with extreme heatwaves, deadly weather events, and devastating wildfires affecting people around the world. No individual or economy on the planet is immune [to] the health threats of climate change. The relentless expansion of fossil fuels and record-breaking greenhouse gas emissions compounds these dangerous health impacts, and is threatening to reverse the limited progress made so far and put a healthy future further out of reach."

The report finds that in 2023, extreme drought lasting at least one month affected 48% of the global land area, while people had to cope with an unprecedented 50 more days of health-threatening temperatures than would have been expected without the climate crisis. As a result, 151 million more people faced moderate or severe food insecurity, risking malnutrition and other harm to their health.

An anonymous reader quotes a report from the European Space Agency: White dots arranged in five clusters against a black background (PNG). This is the simulated extraterrestrial signal transmitted from Mars and deciphered by a father and a daughter on Earth after a year-long decoding effort. On June 7, 2024, media artist Daniela de Paulis received this simple, retro-looking image depicting five amino acids in her inbox. It was the solution to a cosmic puzzle beamed from ESA's ExoMars Trace Gas Orbiter (TGO) in May 2023, when the European spacecraft played alien as part of the multidisciplinary art project 'A Sign in Space.' After three radio astronomy observatories on Earth intercepted the signal, the challenge was first to extract the message from the raw data of the radio signal, and secondly to decode it. In just 10 days, a community of 5000 citizen scientists gathered online and managed to extract the signal. The second task took longer and required some visionary minds.

US citizens Ken and Keli Chaffin cracked the code following their intuition and running simulations for hours and days on end. The father and daughter team discovered that the message contained movement, suggesting some sort of cellular formation and life forms. Amino acids and proteins are the building blocks of life. Now that the cryptic signal has been deciphered, the quest for meaning begins. The interpretation of the message, like any art piece, remains open. Daniela crafted the message with a small group of astronomers and computer scientists, with support from ESA, the SETI Institute and the Green Bank Observatory. The artist and collaborators behind the project are now taking a step back and witnessing how citizen scientists are shaping the challenge on their own.

The concentration of planet-heating pollutants clogging the atmosphere hit record levels in 2023, the World Meteorological Organization (WMO) has said. From a report: It found carbon dioxide is accumulating faster than at any time in human history, with concentrations having risen by more than 10% in just two decades. "Another year, another record," said Celeste Saulo, secretary-general of the WMO. "This should set alarm bells ringing among decision makers." The increase was driven by humanity's "stubbornly high" burning of fossil fuels, the WMO found, and made worse by big wildfires and a possible drop in the ability of trees to absorb carbon. The concentration of CO2 reached 420 parts per million (ppm) in 2023, the scientists observed. The level of pollution is 51% greater than before the Industrial Revolution, when people began to burn large amounts of coal, oil and fossil gas.

Ars Technica's Stephen Clark reports: For those who follow NASA's human spaceflight program, a burning question for the last year-and-a-half has been what caused the Orion spacecraft's heat shield to crack and chip away during atmospheric reentry on the unpiloted Artemis I test flight in late 2022. Multiple NASA officials said Monday they now know the answer, but they're not telling. Instead, agency officials want to wait until more reviews are done to determine what this means for Artemis II, the Orion spacecraft's first crew mission around the Moon, officially scheduled for launch in September 2025.

"We have gotten to a root cause," said Lakiesha Hawkins, assistant deputy associate administrator for NASA's Moon to Mars program office, in response to a question from Ars on Monday at the Wernher von Braun Space Exploration Symposium. "We are having conversations within the agency to make sure that we have a good understanding of not only what's going on with the heat shield, but also next steps and how that actually applies to the course that we take for Artemis II," she said. "And we'll be in a position to be able to share where we are with that hopefully before the end of the year."

While the space program is far down the list of most voters' priorities, this means a decision and announcement on what will happen with Artemis II won't come until the post-election lame duck period in the waning weeks of the Biden administration, and likely Bill Nelson's tenure as NASA administrator. This is several months later than NASA officials expected to make a decision. The question here is whether NASA managers decide it is safe enough to fly the Orion heat shield as-is on Artemis II, or if it is too risky with people onboard. Artemis II will be a 10-day mission taking its four-person crew on a path around the far side of the Moon, then back to Earth. This will be the first time people travel to such distances since the Apollo program ended more than 50 years ago.

When SpaceX developed reusable boosters for its Falcon rockets, it helped cut costs of launches.

Now the Wall Street Journal reports that last week's first-time catch of "its huge Starship booster" could "extend SpaceX's cost advantages, especially in launches to low-Earth orbit, where SpaceX and others operate satellites." A fully and rapidly reusable Starship would push down SpaceX's costs by limiting the need to crank out new hardware and cutting downtime between flights, space industry executives say. Bain, the consulting firm, has estimated that Starship would reduce the cost of getting each kilogram to low-Earth orbit by 50 to 80 times... SpaceX's rocket peers are moving toward reusability, but they are behind the progress Musk's company has made.

- The huge booster that will power New Glenn, the orbital rocket Jeff Bezos' Blue Origin is developing, is designed to be reusable. That rocket is slated to launch for the first time next month.

- ULA, the rocket operator owned by Boeing and Lockheed Martin, is looking to recover the two engines that help power the first part of its new rocket, Vulcan Centaur. The parent company for Arianespace, whose new vehicle is powered by an expendable booster, has also invested in a startup developing a reusable booster.

- Last year, Rocket Lab USA used an engine that had flown before on a flight of its Electron rocket, and is working on a new vehicle, called Neutron, with a booster it could use again.

- Jason Kim, chief executive of Firefly Aerospace, said the reusable vehicle the Texas-based company is developing with Northrop Grumman would give launch customers more flexibility and better pricing. "It really comes down to the affordability and the schedule," Kim said in a recent interview.
"We need reusability for rockets, just like we have reusability for cars, for airplanes, for bicycles, for horses," Musk said in a video SpaceX posted earlier this year...

In Iceland, "a volcanic system has awoken after an 800-year slumber," according to a multimedia CNN Special Report. "But in another part of Iceland, scientists and engineers are hoping to harness magma's immense power to solve the planet's biggest problem..."

It all started in 2009 when Bjarni Pálsson, an engineer with Iceland's national power company, accidentally drilled into a magma chamber. "Armed with new technology and know-how, he is going back in..." The ambition of the geothermal experts and volcanologists that comprise the Krafla Magma Testbed is to convert the immense heat and pressure into a new "limitless" form of supercharged geothermal energy — a tantalizing prospect as the world struggles to end its relationship with planet-heating fossil fuels. "This has never been done before," said Hjalti Páll Ingólfsson, director of the Geothermal Research Cluster, which developed the project....

If all goes to plan, the first borehole will be completed in 2027 and will mark the first time anyone has ever implanted sensors directly into a magma chamber... If the first drilling experiment succeeds, the team will move onto the second borehole, due to be completed in 2029 — and this could be the global gamechanger. It's here the team will attempt to harness the intense heat of magma to produce a new kind of extreme geothermal energy, many times more powerful than conventional...

If they succeed, the implications could reverberate around the world, Ingólfsson said. There are an estimated 800 million people living within roughly 60 miles of an active volcano.
The report includes a map showing volcano sites around the earth where similar drilling could theoretically unleash the same intense magma-powered extreme geothermal energy.

Iceland's plan is to drill down 1.2 miles — about 2 kilometers — into a magma chamber that's around 1,800 Fahrenheit (nearly 1,000 degrees Celsius). The engineering feat "won't be easy," the article acknowledges. "But as humans heat the planet at record speed with fossil fuel pollution, there is increasing pressure to perform moonshot feats of engineering to save us from ourselves."

"We passed Berkeley air — just outdoor air — into the material to see how it would perform," says U.C. Berkeley chemistry professor Omar Yaghi, "and it was beautiful.

"It cleaned the air entirely of CO2," Yaghi says in an announcement from the university. "Everything."

SFGate calls it "a discovery that could help potentially mitigate the effects of climate change..." Yaghi's lab has worked on carbon capture since the 1990s and began work on these crystalline structures in 2005. The innovative substance has lots of tiny holes, making it "great for storing gases or liquids, much like a sponge holds water," Yaghi said... While it could take one to two years for the powder to be usable in large-scale applications, Yaghi co-founded Atoco, an Irvine company, to commercialize his research and expand it beyond just carbon capture and storage.
"Capturing carbon from the air just got easier," says the headline on the anouncement from the university, which explains why this technology is crucial: [T]oday's carbon capture technologies work well only for concentrated sources of carbon, such as power plant exhaust. The same methods cannot efficiently capture carbon dioxide from ambient air, where concentrations are hundreds of times lower than in flue gases. Yet direct air capture, or DAC, is being counted on to reverse the rise of CO2 levels, which have reached 426 parts per million, 50% higher than levels before the Industrial Revolution. Without it, according to the Intergovernmental Panel on Climate Change, we won't reach humanity's goal of limiting warming to 1.5 degreesC (2.7 degreesF) above preexisting global averages.

A new type of absorbing material developed by chemists at the University of California, Berkeley, could help get the world to negative emissions... According to Yaghi, the new material could be substituted easily into carbon capture systems already deployed or being piloted to remove CO2 from refinery emissions and capture atmospheric CO2 for storage underground. UC Berkeley graduate student Zihui Zhou, the paper's first author, said that a mere 200 grams of the material, a bit less than half a pound, can take up as much CO2 in a year — 20 kilograms (44 pounds) — as a tree.
Their research was published this week in the journal Nature.

And it's also interesting that they're using AI, according to the university's announcement: Yaghi is optimistic that artificial intelligence can help speed up the design of even better COFs and MOFs for carbon capture or other purposes, specifically by identifying the chemical conditions required to synthesize their crystalline structures. He is scientific director of a research center at UC Berkeley, the Bakar Institute of Digital Materials for the Planet (BIDMaP), which employs AI to develop cost-efficient, easily deployable versions of MOFs and COFs to help limit and address the impacts of climate change. "We're very, very excited about blending AI with the chemistry that we've been doing," he said.
Another potential use could be for harvesting water from desert air for drinking water, Yaghi told SFGate. But he seems very focused specifically on carbon capture.

"Another thing is that we need a strong determination among officials and industries to make carbon capture a high priority. Things have to change, but I believe that direct carbon capture from air is very doable."

"After safely splashing down on Earth as part of NASA's SpaceX Crew-8 mission Friday, a NASA astronaut experienced a medical issue," NASA reported Friday.

But today there's an update: After an overnight stay at Ascension Sacred Heart Pensacola in Florida, the NASA astronaut was released and returned to NASA's Johnson Space Center in Houston Saturday. The crew member is in good health and will resume normal post-flight reconditioning with other crew members.

As part of NASA's SpaceX Crew-8 mission [SpaceX's eighth crew-rotation mission to the ISS], the astronaut was one of four crewmates who safely splashed down aboard their SpaceX Dragon spacecraft near Pensacola on October 25. The crew members completed a 235-day mission, 232 days of which were spent aboard the International Space Station conducting scientific research.

To protect the crew member's medical privacy, specific details on the individual's condition and identity will not be shared.

Climate scientists who were mocked and gaslighted after speaking up about their fears for the future have said acknowledging strong emotions is vital to their work. From a report: The researchers said these feelings should not be suppressed in an attempt to reach supposed objectivity. Seeing climate experts' fears and opinions about the climate crisis as irrelevant suggests science is separate from society and ultimately weakens it, they said.

The researchers said they had been subject to ridicule by some scientists after taking part in a large Guardian survey of experts in May, during which they and many others expressed their feelings of extreme fear about future temperature rises and the world's failure to take sufficient action. They said they had been told they were not qualified to take part in this broad discussion of the climate crisis, were spreading doom and were not impartial.

However, the researchers said that embracing their emotions was necessary to do good science and was a spur to working towards better ways of tackling the climate crisis and the rapidly increasing damage being done to the world. They also said that those dismissing their fears as doom-laden and alarmist were speaking frequently from a position of privilege in western countries, with little direct experience of the effects of the climate crisis.

Scientists from 15 countries warned in an open letter that the potential collapse of the Atlantic Ocean's main circulation system (AMOC) has been "greatly underestimated" and could have devastating global impacts, according to oceanographer Stefan Rahmstorf who spoke to The Guardian. The AMOC system, which moves heat through the northern Atlantic and influences weather patterns across Europe, has shown signs of weakening over the past 60-70 years due to global warming, with indicators including a persistent cold spot in the northern Atlantic and record-low salt levels in seawater.

Rahmstorf, who heads the Earth system analysis department at Germany's Potsdam Institute for Climate Impact Research, estimates a 50% chance of the system reaching a critical tipping point this century, which could trigger severe consequences including regional cooling in northwestern Europe, shifting rainfall patterns, and rising sea levels.

Four astronauts splashed down in the Gulf of Mexico on Friday after their record ISS mission stretched to eight months due to Boeing capsule malfunctions and hurricane disruptions. The SpaceX Dragon capsule landed off Florida's coast before dawn, carrying NASA astronauts Matthew Dominick, Michael Barratt, Jeanette Epps and Russian cosmonaut Alexander Grebenkin.

Technical issues with Boeing's Starliner capsule in September, followed by Hurricane Milton and persistent rough seas, delayed their planned return by two months. The crew launched in March as part of NASA's commercial crew program. Their replacements include Boeing Starliner test pilots Butch Wilmore and Suni Williams, whose mission expanded from eight days to eight months, alongside two SpaceX-launched astronauts. The new crew will remain aboard the station until February.

An anonymous reader quotes a report from Reuters: The European Space Agency is in talks with SpaceX about the possibility of Elon Musk's space venture joining an international charter designed to reduce a growing swarm of debris in space, Director General Josef Aschbacher told Reuters. The 22-nation agency is spearheading one of several efforts to roll back the mass of space junk swirling round the planet from past missions that poses a risk to active satellites. Aschbacher said 110 countries or entities have joined ESA's Zero Debris charter, which aims to stop any new orbital garbage being generated by 2030.

Asked whether SpaceX, whose satellites now make up some two thirds of spacecraft active in low Earth orbit, had signed up, Aschbacher said: "Not yet, but we are in discussion with them... This is a charter that keeps evolving and... we will keep raising the topics because they are so fundamental." [...] There are currently 18,897 pieces of trackable space junk in orbit, according to Jonathan McDowell, a Harvard astronomer who tracks such objects. Space debris and junk are often used interchangeably, but some consider space junk to include inactive payloads and rocket bodies as well as debris, or errant shards of broken satellites. There are no international laws on debris, but countries and space agencies have begun in recent years to devise proposals and national rules for tackling the problem.

An anonymous reader quotes a report from New Scientist: As the world emerged from the lockdowns of the covid-19 pandemic, many countries promised to rebuild their economies in a climate-friendly fashion, amid hopes the recovery effort could accelerate the global journey to net-zero emissions. In reality, the opposite has happened. Instead of a "green recovery," global greenhouse gas emissions are rising much faster now than they did in the decade preceding the global pandemic. Emissions rose 1.3 percent to 57.1 gigatons of carbon dioxide equivalent in 2023. That is a far faster annual rate of growth than during the decade 2010-2019, when emissions grew on average 0.8 percent per year. In fact, global greenhouse gas emissions are now just below the 59.1 gigatons peak recorded in 2019.

All sources of greenhouse gas emissions except land use are rising, according to a report from the United Nations Global Environment Program (UNEP), as economies continued to rebound from covid-19. Emissions from road transport, leaks from oil and gas infrastructure such as pipelines and industrial emissions all grew rapidly in 2023, UNEP said, while aviation emissions grew 19.5 percent. Rising emissions means the world's opportunity to avert catastrophic climate change is shrinking, Inger Anderson at UNEP said in a statement. "Climate crunch time is here," she said. "I urge every nation: no more hot air, please."

AmiMoJo shares a report from Live Science: Scientists have demonstrated a new humanoid robot that can run at a top speed of just over 8 miles per hour (mph) -- or 3.6 meters per second (m/s) to be exact. This makes it the speediest machine of its kind built so far, albeit these speeds were only achieved with the help of added footwear. STAR1 is a bipedal robot built by the Chinese company Robot Era that's 5 feet 7 inches (171 centimeters) tall and weighs 143 pounds (65 kilograms).

Powered by high-torque motors and artificial intelligence (AI) algorithms, the footwear-donning STAR1 navigated different types of terrain, including grassland and gravel, while jogging on paved roads and earth, and sustained its top speed for 34 minutes. A top speed of 8 mph means it beat Unitree's H1 robot -- which set the previous speed record for a bipedal robot at 7.4 mph (3.3 m/s) in March 2024. Although STAR1 had the help of footwear, H1 was not technically jogging or running as its feet did not both leave the ground at once during transit. You can watch STAR1 racing through the Gobi Desert here.

Living in a pollution-free environment is a fundamental right, India's Supreme Court said on Wednesday as it urged authorities to address deteriorating air quality in the north of the country. From a report: India's capital Delhi recorded a "very poor" air quality index of 364 on Wednesday, according to the Central Pollution Control Board, which considers readings below 50 to be good. Swiss group IQAir rated Delhi the world's most polluted city in its live rankings. The city battles toxic air every winter and authorities say much of the smoke comes from farmers illegally burning paddy stubble to clear their fields in the neighbouring breadbasket states of Punjab and Haryana. The Supreme Court pulled up the governments of both states for taking "selective action" against stubble burning, saying penal provisions were not being properly implemented.

An anonymous reader quotes a report from Wired: When Canadian developer Peter Todd found out that a new HBO documentary, Money Electric: The Bitcoin Mystery, was set to identify him as Satoshi Nakamoto, the creator of Bitcoin, he was mostly just pissed. "This was clearly going to be a circus," Todd told WIRED in an email. The identity of the person -- or people -- who created Bitcoin has been the subject of speculation since December 2010, when they disappeared from public view. The mystery has proved all the more irresistible for the trove of bitcoin Satoshi is widely believed to have controlled, suspected to be worth many billions of dollars today. When the documentary was released on October 8, Todd joined a long line of alleged Satoshis.

Documentary maker Cullen Hoback, who in a previous film claimed to have identified the individual behind QAnon, laid out his theory to Todd on camera. The confrontation would become the climactic scene of the documentary. But Todd nonetheless claims he didn't see it coming; he alleges he was left with the impression the film was about the history of Bitcoin, not the identity of its creator. Since the documentary aired, Todd has repeatedly and categorically denied that he created Bitcoin: "For the record, I am not Satoshi," he alleges. "I think Cullen made the Satoshi accusation for marketing. He needed a way to get attention for his film."

For his part, Hoback remains confident in his conclusions. The various denials and deflections from Todd, he claims, are part of a grand and layered misdirection. "While of course we can't outright say he is Satoshi, I think that we make a very strong case," says Hoback. Whatever the truth, Todd will now bear the burden of having been unmasked as Satoshi. He has gone into hiding. [...] Todd expects that "continued harassment by crazy people" will become the indefinite status quo. But he says the potential personal safety implications are his chief concern -- and the reason he has gone into hiding. "Obviously, falsely claiming that ordinary people of ordinary wealth are extraordinarily rich exposes them to threats like robbery and kidnapping," says Todd. "Not only is the question dumb, it's dangerous. Satoshi obviously didn't want to be found, for good reasons, and no one should help people trying to find Satoshi." "I think the idea that it puts their life [at risk] is a little overblown," says Hoback. "This person is potentially on track to become the wealthiest on Earth."

"If countries are considering adopting this in their treasuries or making it legal tender, the idea that there's potentially this anonymous figure out there who controls one twentieth of the total supply of digital gold is pretty important."

Amazon has reached its goal set earlier this year to completely get rid of plastic air pillows at its warehouses by the end of the year. "As of October 2024, we've removed all plastic air pillows from our delivery packaging used at our global fulfillment centers," the e-commerce giant said in an October 9th blog post. The Verge reports: It's a welcome change following years of pressure from environmental groups to stop plastic pollution flooding into oceans. The company is still working to reduce the use of single-use plastics more broadly in its packaging. The most prolific type of plastic litter near coastlines is plastic film -- a material that makes up those once ubiquitous air pillows, according to Oceana. That film also happens to be the "deadliest" type of plastic pollution for large mammals like whales and dolphins that might ingest it, Oceana says.

The company swapped out plastic air pillows and single-use delivery bags for paper and cardboard alternatives in Europe in 2022. It also ditched plastic film packaging at its facilities in India in 2020. The US is Amazon's largest market, and the company hasn't managed to fully eliminate plastic packaging in North America just yet. It says it plans to reduce the amount of deliveries containing "Amazon-added plastic delivery packaging" in North America to just one-third of shipments by December, down from two-thirds in December 2023.
