U.S. commercial trucks are getting greener thanks to wider adoption of the newest clean diesel technologies, according to research from the Diesel Technology Forum, released October 22.

The newest near-zero emissions diesel truck engines make up nearly half of the U.S. fleet, the research shows. Of the nearly 11-million diesel-powered commercial trucks on the road—from box delivery trucks to 18-wheelers—43% are powered by the newest, cleanest diesel engines. That's double the number of clean-diesel-powered trucks in 2015 and a nearly 7% increase between December 2017 and July 2019, the researchers said.

These new technologies have eliminated 126 million metric tons of carbon dioxide (CO2), 18 million metric tons of nitrogen oxides (NOx), and 1 million metric tons of particulate matter (PM) since 2007, the researchers said. They have also saved 12.4 billion gallons of diesel fuel and 296 million barrels of crude oil in that time, according to the research.

"As more of America's commercial trucks rely on the newest, cleanest diesel technologies, greater air quality and fuel savings benefits are being realized by communities across the country," Allen Schaeffer, executive director of the Diesel Technology Forum, said in a statement announcing the research. "... the emissions and fuel savings attributable to new-generation diesel engines in commercial trucks is astounding: they equate to making 26 million cars all-electric, eliminating the PM emissions from all U.S. cars for 33 years, achieving carbon sequestration in a forest roughly the size of Texas, or creating a 27,000-turbine wind farm on land four times the size of Washington, D.C.—all benefits achieved thanks to the increasing adoption of the newest generation of advanced diesel engines."

The Diesel Technology Forum projects even greater environmental gains ahead. By 2030, savings are estimated to grow to 1.3 billion metric tons of CO2, 73 million metric tons of NOx, 4 million metric tons of PM, 130 billion gallons of diesel, and 33.1 billion barrels of crude oil, the research showed.

The Diesel Technology Forum analyzed 2018-2019 U.S. data for Class 3-8 vehicles, provided by research firm IHS Markit, for its October report.

North American manufacturers embrace “factory of the future”

Manufacturing enterprises in North America are breaking with tradition to harness the power of artificial intelligence (AI) and machine learning (ML) as they seek to compete amid new technologies, consumer demands, and economic shifts, according to a report from the research and advisory firm Information Services Group (ISG).

That changing landscape is forcing companies to adapt or replace their traditional approaches to product design and production. Specifically, many are changing the way they run factories by optimizing supply chains, increasing sustainability, and integrating after-sales services into their business models.

chart of women's portion of transport and storage jobs

Women hold only 12% of transportation and storage jobs worldwide

Women are significantly underrepresented in the global transport sector workforce, comprising only 12% of transportation and storage workers worldwide as they face hurdles such as unfavorable workplace policies and significant gender gaps in operational, technical and leadership roles, a study from the World Bank Group shows.

This underrepresentation limits diverse perspectives in service design and decision-making, negatively affects businesses and undermines economic growth, according to the report, “Addressing Barriers to Women’s Participation in Transport.” The paper—which covers global trends and provides in-depth analysis of the women’s role in the transport sector in Europe and Central Asia (ECA) and Middle East and North Africa (MENA)—was prepared jointly by the World Bank Group, the Asian Development Bank (ADB), the German Agency for International Cooperation (GIZ), the European Investment Bank (EIB), and the International Transport Forum (ITF).

How clever is that chatbot?

Oh, you work in logistics, too? Then you’ve probably met my friends Truedi, Lumi, and Roger.

No, you haven’t swapped business cards with those guys or eaten appetizers together at a trade-show social hour. But the chances are good that you’ve had conversations with them. That’s because they’re the online chatbots “employed” by three companies operating in the supply chain arena—TrueCommerce, Blue Yonder, and Truckstop. And there’s more where they came from. A number of other logistics-focused companies—like ChargePoint, Packsize, FedEx, and Inspectorio—have also jumped in the game.

Experts: U.S. companies need strategies to pay costs of Trump tariffs

With the hourglass dwindling before steep tariffs threatened by the new Trump Administration will impose new taxes on U.S. companies importing goods from abroad, organizations need to deploy strategies to handle those spiraling costs.

American companies with far-flung supply chains have been hanging for weeks in a “wait-and-see” situation to learn if they will have to pay increased fees to U.S. Customs and Border Enforcement agents for every container they import from certain nations. After paying those levies, companies face the stark choice of either cutting their own profit margins or passing the increased cost on to U.S. consumers in the form of higher prices.
