The aftermath of the recent election has sparked discussions about how the change in administration will impact various economic sectors, including the trucking industry. Despite the forecasts, two undeniable facts remain: heavy-duty trucks and buses currently have a negative impact on the health and well-being of communities nationwide, and the most effective way to reduce global warming emissions and health impacts in the freight sector is through heavy-duty battery-powered electric trucks powered by a decarbonized grid.
If you are concerned about the consequences of decisions made by your local school board regarding school buses, or if you want to understand the health costs and emissions of the delivery trucks in your area, the Union of Concerned Scientists (UCS) has the answers. A new tool has been developed by UCS to compare different types of trucks, providing detailed insights into cleaning up the freight sector.
The analysis conducted by UCS considered a range of factors when evaluating various truck and fueling infrastructure options. This included different types of trucks such as delivery vans, garbage trucks, school buses, and tractor-trailers, as well as different powertrain types and energy sources. Additionally, the analysis looked at different model years and energy futures, including a baseline scenario and a decarbonized grid scenario.
To calculate the impact of each truck, UCS considered both total global warming emissions and total health impacts related to the use of the vehicles over their lifetime. Health impacts were estimated using the EPA’s COBRA model, which takes into account air quality modeling and population data to assess the incidence of health issues related to truck emissions.
The results of the analysis consistently showed that battery-electric trucks had the lowest global warming emissions and generally had the lowest public health impacts across all scenarios. Even in cases where battery-electric trucks were not the top choice for health impacts, they were not far behind. In comparison, hydrogen fuel cell trucks emitted significantly more global warming emissions over their lifetime, especially when the hydrogen was derived from natural gas.
The UCS tool allows users to explore the data themselves and make informed decisions about advocating for cleaner transportation solutions in their communities. With the need for sustainable and healthy transportation options becoming increasingly urgent, having access to reliable data is crucial for making informed choices that benefit both the environment and public health.
