Criminal Charges Announced Over Multi-Year Fraud Scheme in a Carbon Credits Market

Par : EditorDavid
5 octobre 2024 à 19:34
This week the U.S. Attorney's Office for the Southern District of New York unsealed charges over a "scheme to commit fraud" in carbon markets, which they say fraudulently netted one company "tens of millions of dollars" worth of credits — which led to "securing an investment of over $100 million." MarketWatch reports: Ken Newcombe had spent years building a program to distribute more environmentally friendly cookstoves for free to rural communities in Africa and Southeast Asia. The benefit for his company, C-Quest Capital, would be the carbon credits it would receive in exchange for reducing the amount of fuel people burned in order to cook food — credits the company could then sell for a profit to big oil companies like BP. But when Newcombe tried to ramp up the program, federal prosecutors said in an indictment made public Wednesday, he quickly realized that the stoves wouldn't deliver the emissions savings he had promised investors. Rather than admit his mistake, he and his partners cooked the books instead, prosecutors said... That allowed them to obtain carbon credits worth tens of millions of dollars that they didn't deserve, prosecutors said. On the basis of the fraudulently gained credits, prosecutors said, C-Quest was able to secure $250 million in funding from an outside investor. "The alleged actions of the defendants and their co-conspirators risked undermining the integrity of [the global market for carbon credits], which is an important part of the fight against climate change," said Damian Williams, the U.S. attorney for the Southern District of New York. From announced by the U.S. Attorney's Office: U.S. Attorney Damian Williams said... "The alleged actions of the defendants and their co-conspirators risked undermining the integrity of that market, which is an important part of the fight against climate change. Protecting the sanctity and integrity of the financial markets continues to be a cornerstone initiative for this Office, and we will continue to be vigilant in rooting out fraud in the market for carbon credits...." While most carbon credits are created through, and trade in compliance markets, there is also a voluntary carbon market. Voluntary markets revolve around companies and entities that voluntarily set goals to reduce or offset their carbon emissions, often to align with goals from employees or shareholders. In voluntary markets, the credits are issued by non-governmental organizations, using standards for measuring emission reductions that they develop based on input from market participants, rather than on mandates from governments. The non-governmental organizations issue voluntary carbon credits to project developers that run projects that reduce emissions or remove greenhouse gases from the atmosphere. CQC was a for-profit company that ran projects to generate carbon credits — including a type of credit known as a voluntary carbon unit ("VCU") — by reducing emissions of greenhouse gases. CQC profited by selling VCUs it obtained, often to companies seeking to offset the impact of greenhouse gases they emit in the course of operating their businesses. The company itself was not charged due to "voluntary and timely self-disclosure of misconduct," according to the announcement, along with "full and proactive cooperation, timely and appropriate remediation, and agreement to cancel or void certain voluntary carbon units.

Plastic-Eating Bacteria Could Combat Pollution Problems, Scientists Hope

The Washington Post on scientists who "discovered that bacteria commonly found in wastewater can break down plastic to turn it into a food source, a finding that researchers hope could be a promising answer to combat one of Earth's major pollution problems." In a study published Thursday in Environmental Science and Technology, scientists laid out their examination of Comamonas testosteroni, a bacteria that grows on polyethylene terephthalate, or PET, a plastic commonly found in single-use food packaging and water bottles. PET makes up about 12 percent of global solid waste and 90 million tons of the plastic produced each year... Unlike most other bacteria, which thrive on sugar, C. testosteroni has a more refined palate, including chemically complex materials from plants and plastics that take longer to decompose. The researchers are the first to demonstrate not only that this bacteria can break down plastic, but they also illuminate exactly how they do it. Through six meticulous steps, involving complex imaging and gene editing techniques, the authors found that the bacteria first physically break down plastic by chewing it into smaller pieces. Then, they release enzymes — components of a cell that speed up chemical reactions — to chemically break down the plastic into a carbon-rich food source known as terephthalate... The bacteria take a few months to break down chunks of plastic, according to Rebecca Wilkes [a lead author on the study and postdoctoral researcher at the National Renewable Energy Laboratory]. As a result, if the bacteria are going to be efficient tools, a lot of optimization needs to take place to speed up the rate at which they decompose pollutants. One approach is to promote bacterial growth by providing them with an additional food source, such as a chemical known as acetate. A senior author on the study (and associate professor of civil and environmental engineering at Northwestern University) tells the Washington Post that "The machinery in environmental microbes is still a largely untapped potential for uncovering sustainable solutions we can exploit."

America's FCC Orders T-Mobile To Deliver Better Cybersecurity

Par : EditorDavid
5 octobre 2024 à 17:34
T-Mobile experienced three major data breaches in 2021, 2022, and 2023, according to CSO Online, "which impacted millions of its customers." After a series of investigations by America's Federal Communications Commission, T-Mobile agreed in court to a number of settlement conditions, including moving toward a "modern zero-trust architecture," designating a Chief Information Security Office, implementing phishing-resistant multifactor authentication, and adopting data minimization, data inventory, and data disposal processes designed to limit its collection and retention of customer information. Slashdot reader itwbennett writes: According to a consent decree published on Monday by the U.S. Federal Communications Commission, T-Mobile must pay a $15.75 million penalty and invest an equal amount "to strengthen its cybersecurity program, and develop and implement a compliance plan to protect consumers against similar data breaches in the future." "Implementing these practices will require significant — and long overdue — investments. To do so at T-Mobile's scale will likely require expenditures an order of magnitude greater than the civil penalty here,' the consent decree said. The article points out that order of magnitude greater than $15.75 million would be $157.5 million...

Akamai Warns CUPS Vulnerability Also Brings New Threat of DDoS Attacks

Par : EditorDavid
5 octobre 2024 à 16:34
Last week the Register warned "If you're running the Unix printing system CUPS, with cups-browsed present and enabled, you may be vulnerable to attacks that could lead to your computer being commandeered over the network or internet." (Although the CEO of cybersecurity platform watchTowr told them "the vulnerability impacts less than a single-digit percentage of all deployed internet-facing Linux systems.") But Tuesday generic (Slashdot reader #14,144) shared this new warning from Akamai: Akamai researchers have confirmed a new attack vector using CUPS that could be leveraged to stage distributed denial-of-service (DDoS) attacks. Research shows that, to begin the attack, the attacking system only needs to send a single packet to a vulnerable and exposed CUPS service with internet connectivity. The Akamai Security Intelligence and Response Team (SIRT) found that more than 198,000 devices are vulnerable to this attack vector and are accessible on the public internet; roughly 34% of those could be used for DDoS abuse (58,000+). Of the 58,000+ vulnerable devices, hundreds exhibited an "infinite loop" of requests. The limited resources required to initiate a successful attack highlights the danger: It would take an attacker mere seconds to co-opt every vulnerable CUPS service currently exposed on the internet and cost the attacker less than a single US cent on modern hyperscaler platforms.

Will Hurricanes Prompt More Purchases of Electric Cars?

Par : EditorDavid
5 octobre 2024 à 15:34
Days after a hurricane struck America's southeast, Florida's state's fire marshall "confirmed 16 lithium-ion battery fires related to storm surge," according to local news reports. "Officials said six of those fires are associated with electric vehicles and they are working with fire departments statewide to gather more data." (Earlier this year America's federal transportation safety agency estimated that after a 2022 hurricane "about 36 EVs caught on fire. In several instances, the fire erupted while the impacted EVs were being towed on their flatbed trailers.") But Tuesday, when over 1 million Americans were without electricity, the Atlantic pointed out the other side of the story. "EV owners are using their cars to keep the lights on." When Hurricane Helene knocked out the power in Charlotte, North Carolina, on Friday, Dustin Baker, like many other people across the Southeast, turned to a backup power source. His just happened to be an electric pickup truck. Over the weekend, Baker ran extension cords from the back of his Ford F-150 Lightning, using the truck's battery to keep his refrigerator and freezer running. It worked so well that Baker became an energy Good Samaritan. "I ran another extension cord to my neighbor so they could run two refrigerators they have," he told me. Americans in hurricane territory have long kept diesel-powered generators as a way of life, but electric cars are a leap forward. An EV, at its most fundamental level, is just a big battery on wheels that can be used to power anything, not only the car itself. Some EVs pack enough juice to power a whole home for several days, or a few appliances for even longer. In the aftermath of Helene, as millions of Americans were left without power, many EV owners did just that. A vet clinic that had lost power used an electric F-150 to keep its medicines cold and continue seeing patients during the blackout. One Tesla Cybertruck owner used his car to power his home after his entire neighborhood lost power. One Louisiana man just ran cords straight from the outlets in the bed of his Tesla Cybertruck, according to the article. "We were able to run my internet router and TV, [plus] lamps, refrigerator, a window AC unit, and fans, as well as several phone, watch, and laptop chargers." Over the course of about 24 hours, he said, all of this activity ran his Cybertruck battery down from 99 percent to 80 percent... Bidirectional charging may prove to be the secret weapon that sells electrification to the South, which has generally remained far behind the West and the Northeast in electric-vehicle purchases. If EVs become widely seen as the best option for blackouts, they could entice not just the climate conscious but also the suburban dads in hurricane country with a core belief in prepping for anything. It will take a lot to overcome the widespread distrust of EVs and anxiety about a new technology, but our loathing of power outages just might do the trick. The article notes that Tesla has confirmed all its electric vehicles will support bidirectional charging by 2025.

"Can you believe that we've been demanding user freedom since 1985?" asks a new blog post at FSF.org: Today, we're celebrating our thirty-ninth anniversary, the "lace year," which represents the intertwined nature and strength of our relationship with the free software community. We wouldn't be here without you, and we are so grateful for everyone who has stood with us, advocating for a world where complete user freedom is the norm and not the exception. As we celebrate our anniversary and reflect on the past thirty-nine years, we feel inspired by how far we've come, not only as a movement but as an organization, and the changes that we've gone through. While we inevitably have challenges ahead, we feel encouraged and eager to take them on knowing that you'll be right there with us, working for a free future for everyone. Here's to many more years of fighting for user freedom! Their suggestions for celebrating include: Try a fully free distribution of GNU/Linux or help someone else give it a try Learn how to encrypt your emails and opt out of bulk surveillance Take a small step with big impact and swap out one nonfree program with one that's truly free If you have an Android phone, download F-Droid, which is a catalogue of hundreds of free software applications Wish us happy birthday on social media. [Which for the FSF is Mastodon, PeerTube, and GNU social.] Join a Free Software Directory (FSD) meeting, which we host every Friday from 16:00 to 19:00 UTC. Become an associate member or gift a membership to a friend Donate $39 to help support free software advocacy Print off stickers of our 39th birthday cake Change your desktop background to an early-2000s-cyberspace-inspired image of our former front desk.

Exxon Mobil's 'Advanced' Technique for Recycling Plastic? Burning It

Par : EditorDavid
30 septembre 2024 à 07:34
An anonymous reader shared this report from the Los Angeles Times: In recent years — as longstanding efforts to recycle plastics have faltered — Exxon Mobil has touted advanced recycling as a groundbreaking technology that will turn the tide on the plastic crisis. But despite its seemingly eco-friendly name, the attorney general's lawsuit denounced advanced recycling as a "public relations stunt" that largely involves superheating plastics to convert them into fuel. At Exxon Mobil's only "advanced recycling" facility in Baytown, Texas, only 8% of plastic is remade into new material, while the remaining 92% is processed into fuel that is later burned. [California attorney general Rob] Bonta's lawsuit seeks a court order to prohibit the company from describing the practice as "advanced recycling," arguing the vast majority of plastic is destroyed. Many environmental advocates and policy experts lauded the legal action as a major step toward ending greenwashing by Exxon Mobil — the world's largest producer of single-use plastic polymer... Advanced recycling, which is also called chemical recycling, is an umbrella term that typically involves heating or dissolving plastic waste to create fuel, chemicals and waxes — a fraction of which can be used to remake plastic. The most common techniques yield only 1% to 14% of the plastic waste, according to a 2023 study by the National Renewable Energy Laboratory. Exxon Mobil has largely used reclaimed plastic for fuel production while ramping up its virgin plastic production, according to Bonta. The executive director of California Communities Against Toxics complains Exxon Mobil's "advanced" recycling is "the same technology we've had since the Industrial Revolution... a blast furnace." (The article also quotes her as asking "How is that better than coal?") And a UCLA researcher who studied the issue blames misperceptions about plastic recycling on "an industry-backed misinformation campaign." He agrees that the reality is "having to burn more oil to turn that plastic back into oil, which you then burn." California's attorney general "alleges Exxon Mobil has had a patent for this technology since 1978, and the company is falsely rebranding it as 'new' and 'advanced'... It recently reemerged after the company learned that the term 'advanced recycling' resonated with members of the public..."

Could Atom-Sized Black Holes Be Detected in Our Solar System?

Par : EditorDavid
30 septembre 2024 à 03:39
Scientific American has surprising news about the possibility of black holes the size of an atom but containing the mass of an asteroid — the so-called "primordial black holes" formed after the birth of the universe which could solve the ongoing mystery of the missing dark matter. These atom-sized black holes "may fly through the inner solar system about once a decade, scientists say... And if they sneak by the moon or Mars, scientists should be able to detect them, a new study shows." If one of these black holes comes near a planet or large moon, it should push the body off course enough to be measurable by current instruments. "As it passes by, the planet starts to wobble," says Sarah R. Geller, a theoretical physicist now at the University of California, Santa Cruz, and co-author of the study, which was published on September 17 in Physical Review D. "The wobble will grow over a few years but eventually it will damp out and go back to zero." Study team member Tung X. Tran, then an undergraduate student at the Massachusetts Institute of Technology, built a computer model of the solar system to see how the distance between Earth and nearby solar system objects would change after a black hole flyby. He found that such an effect would be most noticeable for Mars, whose distance scientists know within about 10 centimeters. For a black hole in the middle of the mass range, "we found that after three years the signal would grow to between one to three meters," Tran says. "That's way above the threshold of precision that we can measure." The Earth-Mars distance is particularly well tracked because scientists have been sending generations of probes and landers to the Red Planet... In a coincidence, an independent team published a paper about its search for signs of primordial black holes flying near Earth in the same issue of Physical Review D. The researchers' simulations found that such signals could be detectable in orbital data from Global Navigation Satellite Systems, as well as gravimeters that measure variations in Earth's gravitational field. "For decades physicists thought dark matter was likely to take the form of so-called weakly interacting massive particles (WIMPs)," the article points out. "Yet generations of ever more sensitive experiments meant to find these particles have come up empty." California astrophysicist Kevork Abazajian tells the site that now in the scientific community, "Primordial black holes are really gaining popularity."
