As global leaders come together during #ClimateWeekNYC to fulfill and increase commitments for reducing carbon emissions, transportation and energy sectors of the economy are a key focus, and advanced diesel technology is already delivering substantial benefits.聽鈥淲hile there is tremendous focus on zero emission technologies for the future, no technology has done more to reduce greenhouse gas emissions today than advanced diesel technology,鈥� said Allen Schaeffer, executive director of the Diesel Technology Forum, a not-for-profit educational group.听听
鈥淭oday diesel engines are delivering substantial benefits to society in the form of efficient and clean power. Thanks to sustained research and investment from leading manufacturers, suppliers and fuel producers, advanced diesel engines have undergone a fundamental transformation in environmental performance while boosting energy efficiency.
鈥淩esearch commissioned by the Diesel Technology Forum confirms that the majority of these significant benefits will be delivered by more efficient diesel trucks, as 80 percent of truck sales by 2030 will still be diesel. New and more efficient commercial diesel trucks on the road in the U.S. since 2007 have already saved nearly 20 billion gallons of fuel and eliminated 202 million metric tons of greenhouse gas emissions (2007 and 2020).聽 These more efficient trucks will have eliminated the same emissions as taking 43 million cars off the road for a year.鈥�
The U.S. Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) further estimate that the Commercial Vehicle Fuel Economy and Greenhouse Gas Reduction Standards Phase 1 rules saved 270 million tons of CO2 and 530 million barrels of oil between 2014 and 2018, and that the Phase 2 rules will save another one billion tons of CO2 and nearly two billion barrels of oil between 2021 and 2027.
鈥淲hile zero-emissions solutions for some applications are planned for the future, few are available today, and analysts predict that diesel engines are expected to continue to dominate the trucking sector well beyond the 2030 timeframe. 聽Even as manufacturers are working to develop new power options such as battery-storage/electrification and hydrogen, the adoption of these solutions at market scale could be well into the future, according to many analysts. 聽This underscores the importance of continued innovation, investment and progress in advanced diesel engines to sustain progress toward meeting national and international climate and clean air goals,鈥� noted Schaeffer.
鈥淭he use of advanced renewable biofuels in diesel engines is growing and is an important opportunity that leverages existing vehicle technology and infrastructure while also delivering meaningful greenhouse gas emissions reductions. 聽In California in 2019, diesel engines using biodiesel and renewable diesel fuels have reduced five times the greenhouse gas emissions than all electric vehicles in that state combined.聽 Low-carbon fuel policies in California and those being considered in other regions, are realizing the cost savings and other benefits of using these fuels compared to zero emission vehicle alternatives that require considerable infrastructure investments and new vehicles to fully realize their benefits.
鈥淭he diverse nature and significance of the challenge to reduce global greenhouse gas emissions dictates that it is not a one-size fits all problem, but instead one where many solutions will be needed. 聽An effective climate policy is also one that balances near term strategies for greenhouse gas emissions reductions alongside investments in future zero-emissions solutions. 聽The advanced generation of diesel technology is part of the technologies that will help meet the climate challenge.鈥�
