The European Union is developing new emissions standards that are aimed at decreasing pollution caused by motor vehicles. New emissions standards are rather widespread, however those being developed in Europe are some of the more stringent standards and many local municipalities are aiming at restricting pollution causing emissions even further. The typical effort behind these standards is to decrease the amount of diesel emissions caused by large long-haul trucks, vans, and buses. In fact, the European Union’s Mobility Package proposal calls for a 15 percent reduction of all CO2 emissions by 2025. Levels of emissions will be 30 percent lower than current 2021 goals by the year 2030. Specific targets for large vehicles, such as trucks and semis, are being developed currently and will be set in place sometime in 2018.
Currently, emissions goals cover small passenger vehicles as well as larger vehicles such as delivery vans. The problem with this approach is that the emissions produced by smaller vehicles can be limited by current technology very easily, however emissions produced by larger vehicles is more difficult to control. Large vehicles that travel short trips, such as delivery vans in municipal areas, may be good candidates for electric drivetrains because the range traveled during normal deliveries is on the order of several miles or less. Electric drivetrains produce no emissions, however the range of electric vehicles is limited to the capacity of the batteries, which can be expensive to produce.
For long-haul trucking, diesel will still be necessary for some time. Unfortunately, the cost of developing proper infrastructure, as well as unit development costs of batteries and electric drivetrains, will keep diesel as the front-runner for fueling long-range deliveries and cross-country shipping. Other transitional options away from diesel, such as natural gas or hydrogen power, are options that may be worth investigating to reduce emissions from long-range heavy equipment.
