Meetingall of these goals requires a bold transformation in all sectors including stationary, industrial, residential, and transportation with significant contributions from public agencies, private businesses and individuals.

Mobile sources and the fossil fuels that power them are the largest contributors to the formation of ozone, greenhouse gas emissions, fine particulate matter (PM2.5), and toxic diesel particulate matter. In California, they are responsible for approximately 80% of smog-forming nitrogen oxide (NOx) emissions. They also represent about 50% of greenhouse gas emissions when including emissions from fuel production, and more than 95% of toxic diesel particulate matter emissions. Zero-emission vehicles have no tailpipe emissions. When compared to diesel vehicles, they are two to five times more energy efficient, reduce dependence on petroleum, and reduce GHG emissions substantially.

The Advanced Clean Truck Regulation is part of a holistic approach to accelerate a large-scale reduction of tailpipe emissions focusing on zero-emission medium-and heavy-duty vehicles from Class 2b to Class 8. The regulation has two components including a manufacturer sales requirement, and a reporting requirement:

Today, electric drivetrains are well suited to operating in congested urban areas for stop-and-go driving where conventional engines are least efficient. Battery-electric and fuel-cell electric trucks, buses, and vans already are being used by fleets that operate locally and have predictable daily use where the trucks return to base to be charged or fueled.

There are more than 70 different models of zero-emission vans, trucks and buses that already are commercially available from several manufacturers. Most trucks and vans operate less than 100 miles per day and several zero-emission configurations are available to serve that need. As technology advances, zero-emission trucks will become suitable for more applications. Most major truck manufacturers have announced plans to introduce market ready zero-emission trucks in the near future.

In many cases, a fleet owner who also owns charging stations and charges trucks overnight can have little to no net electricity costs after the low carbon fuel standard credits in California are included.

Zero-emission trucks have higher upfront costs but have lower operating costs than conventional trucks. Today, the total cost of ownership in California can be comparable to conventional trucks for certain duty cycles without grants or rebates. As battery prices fall and technology continues to improve, the total cost of ownership is expected to become more favorable. Incentives are currently available to offset some or all of the higher vehicle capital costs and some of the early infrastructure costs to help fleets begin reducing tailpipe emissions from conventional internal combustion engine vehicles to zero-emission vehicles now.

Pollution from heavy-duty vehicles contributes to climate change and can exacerbate serious health issues such as respiratory and heart ailments, especially for the 72 million people in the United States who live close to truck freight routes and are more likely to be people of color or come from low-income households.

The first rulemaking of this Clean Trucks Plan is a final rule signed on December 20, 2022, which focuses on reducing emissions that form smog and soot and will apply to heavy-duty engines and vehicles beginning in model year 2027.

The second rulemaking is a final rule announced on March 20, 2024, which focuses on light- and medium-duty vehicles and addresses multi-pollutant emissions, including greenhouse gas emissions and emissions that form smog and soot, for model year 2027 and later commercial pickup trucks and vans.

These additional rulemakings take into consideration recent Congressional action, such as the Inflation Reduction Act of 2022, that the Agency anticipates will lead to greater application of zero-emission vehicle technologies.

The Concept S truck by MAN reduces fuel consumption by 25 percent compared to conventional 40-ton trucks. The integrated truck/trailer combination is aerodynamically designed to reduce drag. It also prevents cyclists from being dragged under the wheels. The front windshield greatly increases driver visibility and safety.

Project Drawdown's Efficient Trucks solution involves the use of selected technologies to reduce medium and large freight truck fuel usage. This solution replaces conventional trucking technologies and approaches.

The impact of trucks on greenhouse gas emissions is oversized. Trucking produces a majority of emissions in the freight industry, with heavy trucks using about 50 percent of all freight industry energy, and light trucks using 20 percent. Comprising just over 4 percent of vehicles in the US and 9 percent of total mileage, trucks consume more than 25 percent of fuel. Worldwide, road freight is responsible for about 6 percent of all emissions.

We defined the total addressable market for efficient trucks as the total worldwide freight demand to 2050. An efficient truck is one with a package of efficiency technologies providing around 40 percent efficiency improvement over conventional vehicles. We estimated current adoption of these technologies (defined as the amount of functional demand supplied in 2018) at 1.6 percent globally of all freight movement, driven in part by fuel efficiency and emissions standards for cleaner trucking.

We calculated impacts of increased adoption of the Efficient Trucks solution from 2020 to 2050 by comparing two growth scenarios with a reference scenario in which the market share was fixed at current levels.

We estimated the cost of upgrading to an efficient truck at US$25,943 and assumed the same as the difference in cost between an efficient truck and a conventional truck. Operating costs included only fuel costs for both the conventional and efficient truck. We derived them from 13 sources, including the IEA and ICCT.

Our results show that the long-haul heavy-truck industry could see a considerable return on investment by adopting typical fuel efficiency technologies. The relatively short payback periods of many fuel efficiency measures, combined with most trucks being commercially deployed on the road for more than a decade, ensure that fuel efficiency provides both greenhouse gas reductions and cost savings for the party paying for fuel. In addition, fuel efficiency helps reduce ambient air pollutants such as sulfur oxide, nitrous oxide, and particulate matter, which contribute to poor air quality. For these and other reasons, we expect adoption to be very high for these technologies. With variations in regulations, fuel costs, road quality, and truck models from region to region, solutions may be customized by country and truck operator.

The adoption of fuel-saving clean technologies offers commercial truck fleets clear potential to significantly reduce global greenhouse gas emissions while generating considerable cost savings. However, there is a critical need for policy guidance to help small operators realize the financial benefits of long-term investment in these technologies.

A truck or lorry is a motor vehicle designed to transport freight, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a "tractor".[1]

The majority of trucks currently in use are powered by diesel engines, although small- to medium-size trucks with gasoline engines exist in North America. The market-share of electrically powered trucks is growing rapidly, expected to reach 7% globally by 2027, and are already in service in various roles.[2] In the European Union, vehicles with a gross combination mass of up to 3.5 t (3.4 long tons; 3.9 short tons) are defined as light commercial vehicles, and those over as large goods vehicles.

Trucks and cars have a common ancestor: the steam-powered fardier Nicolas-Joseph Cugnot built in 1769.[citation needed] However, steam wagons were not common until the mid-19th century. The roads of the time, built for horse and carriages, limited these vehicles to very short hauls, usually from a factory to the nearest railway station. The first semi-trailer appeared in 1881,[citation needed] towed by a steam tractor manufactured by De Dion-Bouton. Steam-powered wagons were sold in France and the United States until the eve of World War I, and 1935 in the United Kingdom, when a change in road tax rules made them uneconomic against the new diesel lorries.

In 1895, Karl Benz designed and built the first internal combustion truck. Later that year some of Benz's trucks were modified to become busses by Netphener. A year later, in 1896, another internal combustion engine truck was built by Gottlieb Daimler, the Daimler Motor Lastwagen.[3] Other companies, such as Peugeot, Renault and Bssing, also built their own versions. The first truck in the United States was built by Autocar in 1899 and was available with 5 or 8 horsepower (4 or 6 kW) engines.[4] Another early American truck was built by George Eldridge of Des Moines, Iowa, in 1903. It was powered by an engine with two opposed cylinders, and had a chain drive[5] A 1903 Eldridge truck is displayed at the Iowa 80 Trucking Museum, Walcott, Iowa. Trucks of the era mostly used two-cylinder engines and had a carrying capacity of 1.5 to 2 t (3,300 to 4,400 lb). After World War I, several advances were made: electric starters, and 4, 6, and 8 cylinder engines.
