National postal companies Swiss Post and Austrian Post have committed to electrify their delivery fleets by 2030. The company already operates the largest electric vehicle fleet in the country and will switch more than 9,000 vehicles to electric as part of EV100. Austrian Post is the largest logistics business in Austria.
I recently read a brilliant book, Malcolm Gladwells, Revenge of the Tipping Point that alerted me to the fact that just five per cent of the passenger vehicles on the road produce more than half of all the pollution in the air. Pollution would drop by the same amount as the 10 per cent shift.
When fully implemented, the e-trucks will reduce Danfoss’ scope 1 and 2 emissions in Denmark by 10-15% with the added benefit of next to zero noise and air pollution, thereby ensuring an improved working climate for drivers. With this transformation, Danfoss will be the first company in Denmark to have a 24-hour truck in operation.

The combination of both increased the efficiency to 33%.
Heavy-duty trucks can emit drastically higher levels of pollution when not equipped with required emissions controls. Transport companies must comply with California’s rule to improve air quality and protect adjacent schools and communities from breathing these toxic pollutants.

In the pilot, Boulder will connect one of its electric fleet vehicles to the V2B charging system, which also connects to the recreation center’s electricity system. The fleet car will charge at night, when building energy demand is low, and discharge the battery to the recreation center during the day, when the building’s demand peaks.
into locally produced, renewable hydrogen for Hyzon’s fleet of zero-emission commercial vehicles. 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases) added—it is actually evacuated from the process so there is zero combustion inside the rotary reformer.

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. —Saliba et al.
The report also assesses compliance performance for individual automakers and for the US fleet as a whole with the greenhouse gas emissions standards for light-duty vehicles. Since MY 2004, fuel economy and CO 2 emissions have improved in eleven out of thirteen years. Estimated Real-World CO 2 and Fuel Economy. Source: EPA.
Separately, the Board adopted amendments to improve its Enhanced Fleet Modernization Program (EFMP), or ‘car scrap,’ program. The EFMP’s successful retirement-only component incentivizes California motorists to voluntarily retire older, higher polluting vehicles and light- and medium-duty trucks.
Methane, the key component in natural gas, is usually just burned for heat, combining with oxygen in the atmosphere to form carbon dioxide, the predominant greenhouse gas. Fuel-cell vehicle fleet operators can take advantage of distributed manufacturing and strategic siting of refueling stations.
Southern California Edison has set fleet electrification goals for 2030: 100% of its light-duty vehicles, 30% of medium-duty vehicles, 8% of heavy-duty vehicles, and 60% of forklifts.

A fleet of second-generation FLXdrives will be commercialized and could enter supply chain routes in the next few years. —Eric Gebhardt, Wabtec Chief Technology Officer.
Proponents claim that if renewable electricity is used and CO 2 is captured from the air, then the e-gasoline and e-diesel are climate-neutral fuels that will also reduce pollution. A 10% blend was chosen due to existing fleet and EN228 standard compatibility. However, said T&E, particle pollution was far from eliminated.
mile pipeline that will bring the carbon-neutral renewable natural gas into the SoCalGas distribution system. Up to 320 of CR&R’s recycling and waste collection vehicles operating in Southern California will use this zero-carbon fuel. The trucks are being fueled from special storage trailers while SoCalGas completes a 1.4-mile

As on a volumetric basis, diesel contains more carbon than gasoline, the tax on diesel fuel would increase. However, because diesel-powered cars are more fuel-efficient, some authors argue that dieselization of the passenger car fleet should be increased to decrease CO 2 emissions.
The primary regulated air pollutants (criteria pollutants) are particulate matter (PM), nitrogen oxides (NO x ), carbon monoxide (CO) and volatile organic compounds (VOCs). Hydrocarbons are key precursors to two priority air pollutants, ozone and particulate matter. —Dunmore et al. Dunmore et al. Dunmore et al.
