Real-world CO2 emissions from cars and vans in Europe are 20% higher than certification values
EU Commission finds real-world CO2 emissions from cars and vans in Europe greatly exceed lab certification values. Plug-in hybrids are not being charged as much as estimated.
US EPA MY 2027-2032 Heavy-Duty Phase 3 GHG Standards
The U.S. EPA has finalized the Phase 3 GHG rule specifying CO2 emission reductions from heavy-duty trucks and buses over MY 2027 – 2032.
US EPA MY 2027-2032 Light-Duty CO2 Standards
The EPA final rule will require a fleet averaged 50% reduction in CO2 emissions for light-duty vehicles, over MY 2027 – 2032.
Cummins latest 15L engine capable of meeting MY2027 EPA regulations
Cummins has announced the next generation X15 diesel engine with improved performance and meeting the MY 2027 EPA/CARB Low NOx regulations.

True total cost of ownership still a decade away
New study analyzes the cost of transition to electric vehicles in California, including socio-economic factors. The burden will shift to lower income groups in later years.
Summary of Oct 2023 CARB workshop for Tier 5 non-road standards
California is looking to reduce NOx emissions from non-road engines by 90% and enforce particulate filters on all engines. Here is a summary of the latest workshop to get stakeholder feedback on Tier 5 standards.
Heavy-Duty
CARB and EPA Low NOx Engines and Trucks Announced
Truck manufacturers are offering improved versions that meet California’s MY 2024 Low NOx standards. Here’s a comparison of the underlying after-treatment technologies.
Hybridization of heavy-duty vehicles for meeting European CO2 standards
A summary of a new study highlighting the role hybrids could play in meeting upcoming CO2 standards in Europe, and the implications for electric vehicle share.
Dinex outlines Technologies for Low NOx Non-Road engines
A potential technology pathway for meeting upcoming California low NOx standards for off-highway machinery was shown by Dinex at a recent conference.
Total Cost of Transportation Analysis for a Heavy-Duty Fleet
A new study shows that switching to a Class 8 truck can more than double the total cost of transportation. Here’s a summary.
ACT 2024 in pictures
The ACT Expo, 2024 covered all aspects of the latest technologies for commercial vehicles and provided a unique forum to discuss the “reality” on the ground for the energy transition. Here is a summary in pictures.
How much biofuels can we make, really ?
Lowering the carbon footprint of existing vehicles will require switching to low carbon fuels. The immediate question this raises, is “how much low carbon fuel can we make?” and, “doesn’t using biomass for fuels affect the food production?”
Summary of EV related U.S. Tariffs on Chinese Imports
The Biden Administration has announced significant new tariffs on a range of Chinese-made electric vehicles and related strategic components. Here is a summary.
