carbon emissions

The Department of Energy says idling for more than ten seconds burns more fuel and produces more CO-2 than shutting off and restarting your engine. A 2021 traffic signal report says drivers in Nevada spend more time idling at red lights than drivers in any other state. Nationwide, Americans spend 6.8 percent of each trip at red lights, accounting for…

Tim Menard says artificial intelligence can unclog our roads and reduce red light idling. He started LYT, a cloud-based platform that integrates drivers’ navigation data with a city’s network of traffic signals, analyzes traffic flow, and adjusts traffic light timing accordingly. LX News Storyteller Peter Hull spoke to Menard to learn more about his company, and how it can impact...

Which path will the world take? While some warming is guaranteed, there are still changes that can be made to decrease world carbon emissions and slow the impact of climate change. NBCLX climate storyteller Chase Cain breaks down what we should do next.

While organizations make notable progress on reducing the harmful effects of their operations, experts say sustainability claims can be overstated and mask underlying problems.

Many of the world’s largest companies are failing to take significant enough steps to meet their pledges to vastly reduce the impact of their greenhouse gas emissions in the decades ahead

The ocean around Antarctica is doing its best to help Earth’s atmosphere, and it turns out it’s doing a better job than previously thought. A new NASA-sponsored study says the Southern Ocean is a very effective “carbon sink,” meaning the water absorbs much more carbon from the air than it releases. Researcher Matthew Long explains more about the...

Many states in the U.S. are coming to the conclusion that solar, wind and other renewable power sources might not be enough to keep the lights on as they seek to dramatically cut their use of fossil fuels

Let’s face it. Flying usually sucks. Air travel is also contributing to climate change in a pretty significant way. And that sucks for us and the planet. But what if it didn’t? I could tell the flight I was on was a bit different. First, the flight attendants were using real glassware in coach. And second, their boss, United...

President Joe Biden has signed an executive order to make the federal government carbon-neutral by 2050, with a 65% reduction in planet-warming greenhouse gas emissions by 2030 and an all-electric fleet of cars and trucks five years later.

The world’s top two carbon polluters, China and the United States, have pledged to increase cooperation on climate action in a joint declaration at U.N. climate talks in Glasgow

Global carbon pollution this year has bounced back to almost 2019 levels, after a drop during pandemic lockdowns

The Supreme Court said Friday it will consider whether one of the federal government’s plans for reducing greenhouse gases goes too far. The court agreed to take up a challenge from coal companies and energy-producing states, led by West Virginia, that say the Environmental Protection Agency was exceeding its authority to limit carbon emissions. They’re appealing a lower court’s ruling that restored some...

The state’s largest city has a new ordinance on its books that Mayor Kim Janey’s office is calling “the single most impactful initiative to curb Boston’s carbon emissions.” Janey on Tuesday afternoon signed the City of Boston Building Emissions Reduction and Disclosure Ordinance, which sets emissions targets and reporting requirements for buildings greater than or equal to 20,000 square...

America’s climate summit propelled the world forward on a path toward limiting the worst of global warming

Teen climate activist Greta Thunberg testified Thursday at a Congressional committee hearing on the environment and called out the U.S. for being “biggest emitter in history.”

Alexandria Ocasio-Cortez and Ed Markey continue to promote the Green New Deal, and President Joe Biden announced a commitment to reduce carbon emissions. Energy policy analyst Hal Harvey tells LX we’re at an environmental turning point.

As we approach Earth Day, NBCLX storyteller Cody Broadway asked three experts to imagine what a carbon neutral future would look like, and how the U.S. would get there. Changes would have to come to the auto industry and home heating, among other things – but we’ll also have to figure out who will pay for the shifts in our...

Facilities can filter carbon from air molecules like filtering a glass of water. They’re called Direct Air Capture (DAC) systems and not only can they remove CO2 from ambient air, but they can also assist with storing carbon safely underground.

Massachusetts Gov. Charlie Baker signed a sweeping climate change bill into law Friday, ending months of negotiations as the legislation shuttled back and forth between the Democratic-controlled Legislature and the Republican governor. Baker and lawmakers have both hailed a key goal of the new law — creating a net-zero greenhouse gas emission limit by 2050. “This bill puts us on…

The huge pandemic relief and spending bill includes billions of dollars to promote clean energy such as wind and solar power.
