The transition to cleaner on-road freight is more important now than ever before. As we continue to face the impacts of truck pollution on air quality and climate change, it is crucial to accelerate the adoption of zero-emission trucks (ZETs) in our transportation system. These vehicles, which emit no tailpipe pollution, are becoming more prevalent on the roads across the nation, thanks to advancements in technology and increased availability.
Just a few years ago, ZETs were mostly seen as concept vehicles with limited use. However, today, they are a common sight on the roads, delivering packages and goods to our doorsteps. This growth in the deployment of ZETs has been remarkable, but it has not happened without support. Regulations like California’s Advanced Clean Trucks rule (ACT) have played a key role in driving the availability and adoption of ZETs in the freight industry.
ACT sets clear market signals for manufacturers to produce more ZET models, for utilities and businesses to develop charging infrastructure, and for the supply chain industry to create components for these vehicles. By gradually increasing the share of zero-emission truck and bus models sold through 2035, ACT provides a roadmap for a cleaner and more sustainable future.
The compliance under ACT is determined by a credit system, where manufacturers are required to sell a certain percentage of ZETs each year. Manufacturers who exceed their annual requirement can generate surplus credits that can be traded with other manufacturers. This flexibility in compliance allows manufacturers to transition to cleaner vehicles at a pace that suits their operations.
The impact of ACT is already visible, with ZETs being deployed in states that have adopted the rule at a faster rate than non-adopting states. This accelerated transition to cleaner on-road freight is not only beneficial for reducing air pollution and greenhouse gas emissions but also for saving costs for fleet operators. ZETs offer significant fuel and maintenance savings compared to diesel trucks, making them a cost-effective choice for businesses.
Overall, ACT is paving the way for a more sustainable future for the freight industry. By creating clear market signals and providing feasible compliance pathways for manufacturers, ACT is driving the adoption of cleaner, more efficient vehicles that will benefit both our health and the environment. As we continue to move towards a cleaner transportation system, regulations like ACT will play a crucial role in shaping the future of on-road freight.
