Air Pollution Still Plagues Nearly Half of Americans

1 month 3 weeks ago
An anonymous reader quotes a report from NPR: Air in the U.S. has gotten cleaner for decades, adding years to people's lives and preventing millions of asthma attacks, but nearly half of Americans still live with unhealthy air pollution, a new report finds. The report comes as the Trump administration is considering rolling back some key air quality regulations. Air quality across the country has improved dramatically since regulations like the Clean Air Act were put in place in the 1970s to govern sources of pollution like coal-fired power plants and emissions from diesel trucks. Despite that progress, the air is still unhealthy and polluted in many parts of the country. In 2023, nearly half of the country's inhabitants -- 156 million people -- lived in places heavy in smog or soot pollution that harms their lungs, hearts, and brains, according to the newest edition of the American Lung Association's State of the Air report. "Both these types of pollution cause people to die. They shorten life expectancy and drive increases in asthma rates," says Mary Rice, a pulmonologist at Harvard University. Pollution levels vary widely across the country, the report finds, with the worst soot pollution, averaged over the whole year, centered on California cities like Fresno and Bakersfield. Ozone pollution is highest in the Los Angeles region. Phoenix, Arizona, and Dallas, Texas, also rank in the top 10 most smog-heavy cities. Nationwide, people of color are about twice as likely to live somewhere with high soot and ozone pollution as white Americans. "The Clean Air Act is one of the greatest success stories in our country," says Rice. NPR notes that the law requires the EPA to revisit the science every five years, reassessing what health researchers have learned about the risks of breathing in poor air and adjusting the regulations accordingly. "So the air quality standards have kept pace with the science over time, and levels of fine particulate matter have declined over the last 50-plus years," Rice says. "As a result, life expectancy is longer, and asthma rates have gone down." [...] "We are best equipped to protect our health when we have all the information, like weather and air quality," she says.

Waymo Reports 250,000 Paid Robotaxi Rides Per Week In US

1 month 3 weeks ago
Waymo is now providing over 250,000 paid robotaxi rides per week in the U.S., up from 200,000 in February, as it expands into cities like Austin and grows partnerships with Uber and automakers. CNBC reports: "We can't possibly do it all ourselves," said Pichai on a call with analysts for Alphabet's first-quarter earnings. Pichai noted that Waymo has not entirely defined its long-term business model, and there is "future optionality around personal ownership" of vehicles equipped with Waymo's self-driving technology. The company is also exploring the ways it can scale up its operations, he said. The 250,000 paid rides per week are up from 200,000 in February, before Waymo opened in Austin and expanded in the San Francisco Bay Area in March. Waymo, which is part of Alphabet's Other Bets segment, is already running its commercial, driverless ride-hailing services in the San Francisco, Los Angeles, Phoenix and Austin regions.

US Agency To Ease Self-Driving Vehicle Deployment Hurdles, Retain Reporting Rules

1 month 3 weeks ago
The Trump administration introduced a new framework to expedite self-driving vehicle deployment by reducing regulatory hurdles, while maintaining mandatory safety incident reporting. NHTSA is also expanding its exemption program, allowing domestically produced autonomous vehicles lacking traditional safety controls to operate on U.S. roads. Reuters reports: The Trump administration said Thursday it aims to speed up the deployment of self-driving vehicles but will maintain rules requiring reporting of safety incidents involving advanced vehicles. U.S. Transportation Secretary Sean Duffy on Thursday released a new framework to boost autonomous vehicles. "This administration understands that we're in a race with China to out-innovate, and the stakes couldn't be higher," Duffy said. "Our new framework will slash red tape." The National Highway Traffic Safety Administration said it will expand a program to exempt some self-driving vehicles from all safety requirements and will streamline but continue its requirement that vehicles equipped with certain advanced driver assistance systems or self-driving systems report safety incidents. NHTSA is expanding its Automated Vehicle Exemption Program to now include domestically produced vehicles that will allow companies to operate non-compliant imported vehicles on U.S. roads. It is currently only open to foreign assembled models.
