* Michigan / USA - Trucks have made remarkably little progress in reducing emissions
--- New cars, pickups, and SUVs sold in the U.S. have become remarkably more fuel-efficient, and their contributions to the national carbon footprint have declined significantly. In 1990, these vehicles represented 15.6 percent of total emissions in the U.S.; in 2014 they made up just 16.1 percent, according to a new report by Michael Sivak and Brandon Schoettle, researchers at the University of Michigan’s Transportation Research Institute... Transportation still has a long way to go in reducing emissions. That becomes abundantly clear when considering the growing impact of medium- and heavy-duty vehicles. According to the same report, the share of total U.S. emissions from long-haul trucks, garbage trucks, ambulances and other types of five-ton-and-up mammoths has increased steadily and substantially, from 3.6 percent in 1990 to 6 percent in 2014. Absolute emissions from passenger vehicles leveled off over that period, but absolute emissions from heavier-duty trucks soared to 76 percent... As Julian Spector reported for CityLab in May, some engineers and entrepreneurs are beginning to confront the challenge, with innovations in battery technology, streamlined design, and calls for updated regulations around truck size and weight. With efficiency in heavy-duty vehicles astoundingly low as is, “even small improvements... can have a big effect on overall emissions,” Spector wrote...

* Maryland / USA - 41% of nation’s commercial trucks use clean diesel engines
--- More than 40 percent of all medium- and heavy-duty diesel commercial trucks in operation in the United States — 4 million of 9.5 million diesel trucks — are now equipped with newer technology clean diesel engines, according to a new Diesel Technology Forum (DTF) analysis... The report includes IHS Automotive vehicles in operation representing Class 3-8 diesel trucks from Model Year 2007 through 2015 in all 50 states and the District of Columbia. Beginning in 2007, all heavy-duty diesel trucks sold had to meet particulate emissions levels of no more than 0.01 grams per brake horse-power hour (g/HP-hr.) — a level near zero... Allen Schaeffer, executive director of the Diesel Technology Forum said, there are now four states – Indiana, Utah, Oklahoma and Texas – where more than 50 percent of the registered diesel trucks are the newer cleaner trucks. And in 2015, Oregon had the largest increase in the nation of newer diesel truck registrations with a 35 percent increase over 2014... California has the largest fleet of commercial truck registrations on an absolute number basis; however, it ranks near the bottom for adoption of newer trucks on a percentage basis, based on the analysis... In December 2000, EPA promulgated a rule that established stringent standards designed to reduce emissions from on-road heavy-duty trucks and buses by up to 95 percent and to cut the allowable levels of sulfur in diesel fuel by 97 percent by 2010. To achieve these new standards, the new clean diesel system relies on an efficient engine and combustion system utilizing the most advanced fuel-injection, turbocharging and engine management strategies coupled with advanced emissions controls and after-treatment technologies including particulate filters and selective catalytic reduction (SCR) systems, all running on ultra-low sulfur diesel fuel...

** Belgium - EU to introduce CO2 emission limits for trucks
--- The European Commission will propose limits for the first time on CO2 emissions from trucks and will also set new fuel efficiency standards for cars and vans from 2020, according to a draft document seen by Reuters... The European Union currently has no limits on truck emissions, unlike other countries such as the United States, China, Japan and Canada, which already have truck fuel efficiency standards... The European Union has a limit of 95 grams of CO2 per kilometer (g/km) by 2021 for cars and vans but has so far not done the same for trucks, which are responsible for around a quarter of road transport emissions and that share of emissions could increase by 2030, according to the Commission... In Europe, the industry, which includes manufacturers Daimler, Renault and Volkswagen, has resisted targets for trucks on the grounds that their different shapes and sizes make a "one-size-fits-all" approach to limiting CO2 emissions difficult and that fuel efficiency has already helped lower their carbon footprint... To prepare the ground for the new limits the Commission will propose a law on the certification of CO2 emissions and fuel consumption of new trucks - namely a CO2 test procedure - as well as a law on monitoring and reporting trucks' fuel consumption... In the United States, standards on truck emissions could lead to a 33 percent reduction of fuel consumption rates from 2010 levels, according to researchers...
