The Biden administration on Tuesday announced stricter standards on smog-forming emissions from trucks, vans and buses starting in the 2027 model year, the first of several federal actions aimed at limiting vehicle pollution.
Medium and heavy-duty trucks represent only about 4% of vehicles in the U.S., but due to their larger size and greater travel distances, the vehicles consume more than 25% of total highway fuel and comprise nearly 30% of highway carbon emissions, according to the Department of Energy.
The new rules from the Environmental Protection Agency are the first update to clean air standards for heavy-duty vehicles in more than 20 years. The standards by 2045 will result in a 48% reduction in nitrogen oxide, a 28% reduction in benzene, a 23% reduction in volatile organic compounds and an 18% reduction in carbon monoxide, all of which can cause health issues for people.
The new rules will also help fight climate change. Nitrogen oxide is roughly 300 times as potent as carbon dioxide at warming the atmosphere and accounts for about 7% of all U.S. greenhouse gas emissions from human activity, according to the EPA.
The agency estimates the standards will result in up to 2,900 fewer premature deaths, 6,700 fewer hospital admissions and emergency department visits, 18,000 fewer cases of childhood asthma and $29 billion in annual net benefits by 2045.

Michael Regan, the administrator of the EPA, said that the actions would protect the health of 72 million people who live near truck freight routes in the U.S., including the most threatened populations in historically polluted communities.
“These rigorous standards, coupled with historic investments from the Inflation Reduction Act and the Bipartisan Infrastructure Law, will accelerate President Biden’s ambitious agenda to overhaul the nation’s trucking fleet, deliver cleaner air, and protect people and the planet,” Regan said in a statement.
Britt Carmon, the federal clean vehicles advocate at the Natural Resources Defense Council, said the new EPA standards fall short and the agency missed a critical opportunity to accelerate the shift to the cleanest vehicles.
“EPA now needs to move quickly to put in place the next round of standards that will accelerate the transition to zero-emitting trucks so that we can all be free from the tailpipe pollution that is harming our health and accelerating climate change,” Carmon said in a statement.
In the spring, the EPA is set to propose separate greenhouse gas standards for heavy-duty vehicles starting in the 2027 model year. The agency also said it will delay making a decision until early next year on California’s requests to set its own heavy-truck emissions rules.
Vickie Patton, general counsel for Environmental Defense Fund, praised the standards and urged the agency to quickly move forward to recognize state standards adopted by states like California that are aiming to phase out diesel fuel.
Jed Mandel, president of the Truck and Engine Manufacturers Association, an industry group, said the agency’s new standards are stringent and would be difficult to implement.
“Ultimately, the success or failure of this rule hinges on the willingness and ability of trucking fleets to invest in purchasing the new technology to replace their older, higher-emitting vehicles,” Mandel said in a statement.
The EPA’s standards will take effect 60 days after publication in the Federal Register.
Renewables and nuclear provided 40.9% of the world’s power generation in 2024, passing the 40% mark for the first time since the 1940s, according to a new global energy think tank Ember report.
Renewables added a record 858 TWh in 2024, 49% more than the previous high in 2022. Solar was the largest contributor for the third year running, adding 474 TWh to reach a share of 6.9%. Solar was the fastest-growing power source (+29%) for the 20th year in a row.
Solar has doubled in just three years, providing more than 2,000 TWh of electricity in 2024. Wind generation also grew to 8.1% of global electricity, while hydro – the single largest renewable source – remained steady at 14% of global electricity.
“Solar power has become the engine of the global energy transition,” said Phil MacDonald, Ember’s managing director. “Paired with battery storage, solar is set to be an unstoppable force. As the fastest-growing and largest source of new electricity, it is critical in meeting the world’s ever-increasing demand for electricity.”
Ember’s sixth annual Global Electricity Review, published today, provides the first comprehensive overview of the global power system in 2024 based on country-level data. It’s published alongside the world’s first open dataset on electricity generation in 2024, covering 88 countries that account for 93% of global electricity demand, as well as historical data for 215 countries.
What drove the rising power demand
The analysis finds that fossil fuels also saw a small 1.4% increase in 2024 due to surging electricity demand, pushing global power sector emissions up 1.6% to an all-time high.
Heatwaves were the main driver of the rise in fossil generation, accounting for almost a fifth (+0.7%) of the increase in global electricity demand in 2024 (+4.0%), mainly through additional use of cooling. Without these temperature effects, fossil fuel generation would have risen by only 0.2%, as clean electricity generation met 96% of the demand growth not caused by hotter temperatures.
“Amid the noise, it’s essential to focus on the real signal,” continued MacDonald. “Hotter weather drove the fossil generation increase in 2024, but we’re very unlikely to see a similar jump in 2025.”
Aside from weather effects, the increasing use of electricity for AI, data centers, EVs, and heat pumps is already contributing to global demand growth. Combined, the growing use of these technologies accounted for a 0.7% increase in global electricity demand in 2024, double what they contributed five years ago.
Clean power will grow faster than demand
Ember’s report shows that clean generation growth is set to outpace faster-rising demand in the coming years, marking the start of a permanent decline in fossil fuel generation. The current expected growth in clean generation would be sufficient to meet a demand increase of 4.1% per year to 2030, which is above expectations for demand growth.
“The world is watching how technologies like AI and EVs will drive electricity demand,” said MacDonald. “It’s clear that booming solar and wind are comfortably set to deliver, and those expecting fossil fuel generation to keep rising will be disappointed.”
Beyond emerging technologies, the growth trajectories of the world’s largest emerging economies will play a crucial role in defining the global outlook. More than half of the increase in solar generation in 2024 was in China, with its clean generation growth meeting 81% of its demand increase in 2024. India’s solar capacity additions in 2024 doubled compared to 2023. These two countries are at the forefront of the drive to clean power and will help tip the balance toward a decline in fossil generation at a global level.
Professor Xunpeng Shi, president of the International Society for Energy Transition Studies (ISETS), said: “The future of the global power system is being shaped in Asia, with China and India at the heart of the energy transition. Their increasing reliance on renewables to power demand growth marks a shift that will redefine the global power sector and accelerate the decline of fossil fuels.”

The next-gen LEAF is almost here, and it’s looking better than ever. This isn’t the electric hatch you are used to seeing. Nissan’s new LEAF EV has more range, a fresh crossover design, and yes, it can finally charge up at Tesla Superchargers with an NACS port. With the official reveal just around the corner, someone already spotted the new LEAF at a Tesla charger in Canada.
Nissan is launching the new LEAF in the US and Canada
A little over a week ago, we finally got our first look at the third-generation LEAF. Nissan’s iconic electric hatch has grown into a “sleek and spacious family-friendly crossover.”
The US and Canada will be the first to see the reimagined LEAF later this year. It will join the Ariya in Nissan’s North American EV lineup as it looks to spark growth in one of its most important markets.
Based on the CMF-EV platform, the same one underpinning the Ariya, Nissan promises the new LEAF will have “significant range improvements.” Although no other details were revealed, Nissan’s vehicle programs chief, Francois Bailly, told TopGear.com that it’s expected to have WLTP driving range of up to 373 miles (600 km).
It will likely be lower on the EPA scale, but anything even close to 300 miles would be a major improvement over the current 212 EPA-estimated miles offered on the 2025 LEAF SV Plus.
The next-gen LEAF will also be Nissan’s first EV to feature an integrated NACS charging port. With its official debut later this year, the new model is out for testing and was just caught testing at a Tesla Supercharger in Canada.
If you didn’t know what vehicle it is, the LEAF is hardly recognizable. The new image from KindelAuto gives us a closer look at the new crossover design. It almost looks like a Tesla sitting in front of the charger.
The new LEAF is one of 10 new and refreshed Nissan vehicles set to launch in the US and Canada. It will arrive later this year, followed by the fourth-gen Rogue in 2026, which will be available as a PHEV for the first time.
Nissan also plans to build a new “adventure-focused SUV” at its Canton, Mississippi, plant in late 2027. The teaser shows what appears to be a rugged electric Xterra. We’ll have to wait for more details on that one.
Nissan will reveal additional info about the upcoming LEAF mid-year. Check back soon for more updates.

The Port of Barcelona launched the Ecocat Tres, a highly efficient, all-electric commuter ferry powered by Molabo’s ARIES i50 electric motors.
Ecocat Tres is the latest zero-emission ferry in Bus Nàutic’s growing electric fleet, providing clean transportation between the Drassanes and Llevant wharves. In just its first three months, the Bus Nàutic service logged over 125,000 sustainable trips. Operated by ALSA and backed by the Port of Barcelona, the initiative offers locals and visitors an eco-friendly way to travel, cutting down on road congestion and air pollution in the bustling city.
Built by Spanish shipbuilder Metaltec Naval, Ecocat Tres is a 15-meter aluminum catamaran that carries up to 84 passengers. It even includes a rooftop deck, offering extra seating and a breezy ride across the port. The ferry runs every 15 to 30 minutes for at least 12 hours each day, with the entire trip taking about 10 minutes.
Under the deck are two powerful 48V Molabo ARIES i50 motors, enabling the electric ferry to hit a top speed of 12 knots. Cruising at its regular operational speed of 5 knots, Ecocat Tres can run efficiently for up to 21 hours on a single charge, making it highly reliable for daily commuters.
Molabo’s motors have a low-voltage setup, which makes them safer to maintain compared to traditional high-voltage electric systems. Passengers also enjoy a smoother, quieter ride thanks to significantly reduced noise and vibrations onboard. Azimut Marine supplied the full propulsion and energy system, which includes two ARIES 50 kW electric drives, 36 batteries providing a total of 216 kWh, fast chargers, and integrated solar panels. Impressively, solar power alone can cover up to 40% of the ferry’s energy needs.
Ecocat Tres will cut around 90 tons of CO2 emissions each year, making a positive impact on Barcelona’s ambitious climate goals.
Port of Barcelona president José Antonio Carbonell said, “This 100% electric, zero-emission passenger ferry is helping us reshape mobility in the port and accelerate the decarbonization of our operations.”
