US reaches $1.5B settlement with Daimler AG over emissions cheating in Mercedes-Benz diesels; civil penalty of $875M

The US Environmental Protection Agency (EPA), USDepartment of Justice (DOJ), and California Air Resources Board (CARB) announced a proposed settlement with Daimler AG and its American subsidiary Mercedes-Benz USA, LLC resolving alleged violations of the Clean Air Act and California law associated with emissions cheating.

Under the proposed settlement, lodged with the US District Court for the District of Columbia, Daimler will recall and repair the emissions systems in Mercedes-Benz diesel vehicles sold in the United States between 2009 and 2016 and pay $875 million in civil penalties and roughly $70.3 million in other penalties.

The company will also extend the warranty period for certain parts in the repaired vehicles, perform projects to mitigate excess ozone-creating nitrogen oxides (NOx) emitted from the vehicles, and implement new internal audit procedures designed to prevent future emissions cheating.

The recall program and federal mitigation project are expected to cost the company about $436,000,000. The company will pay another $110,000,000 to fund mitigation projects in California (California will receive a total of $285.6 million). Taken together, the settlement is valued at about $1.5 billion.

Vehicle manufacturers are required by the Clean Air Act and federal regulations to apply for and receive a certificate of conformity from EPA before selling a new model year vehicle in the United States. As part of the application process, manufacturers must demonstrate through testing that a vehicle meets applicable emissions standards and disclose to EPA all auxiliary emission control devices (AECDs) and any defeat devices installed in the vehicle.

The settlement addresses allegations made in separate civil complaints filed by the US and CARB today in the District of Columbia that, from 2009 to 2016, Daimler manufactured, imported, and sold more than 250,000 diesel Sprinter vans and passenger cars with undisclosed AECDs and defeat devices programmed into the vehicles’ complex emissions control software. These devices cause the vehicles to produce compliant results during emissions testing. But when not running a test, the vehicles’ emissions controls can perform differently, and less effectively, resulting in an increase in NOx emissions above compliant levels.

EPA discovered the defeat devices in Daimler’s vehicles through testing conducted in the wake of the Volkswagen scandal at the National Vehicle and Fuel Emissions Laboratory. The agency found a number of AECDs in Daimler’s diesel vehicles that were not described in the application for the certificate of conformity that purportedly covers each vehicle.

The settlement requires Daimler to implement a recall and repair program to remove all defeat devices from the affected vehicles at no cost to consumers and bring the vehicles into compliance with applicable emissions standards under the Clean Air Act. The repair will consist of a software update and replacement of select hardware, which differs across models and model years.

Daimler must repair at least 85% of the affected passenger cars within two years and at least 85% of the affected vans within three years. The company must also offer an extended warranty covering all updated software and hardware, and it must test repaired vehicles each year for the next five years to ensure the vehicles continue to meet emissions standards over time. Daimler will face stiff penalties if any category of updated vehicles fails to meet applicable emissions standards or if it fails to meet the 85 percent recall rate for passenger cars or vans.

The settlement further requires Daimler to implement systemic corporate reforms to detect and try to eliminate violations in the future. This includes conducting significant testing on new diesel and gasoline motor vehicles using a portable emissions measurement system to assess compliance under real-world conditions, installing a robust whistleblower program, enhancing annual AECD and defeat device training for its employees, and performing internal audits subject to review and critique by an external compliance consultant.

Daimler must also replace 15 old locomotive engines with new, less-polluting engines to offset excess NOx emitted from its vehicles.

The proposed settlement is subject to a 30-day public comment period and court review and approval.

And all this time we were bombarded with PR about how clean and powerful diesels are...still believe it?

Yes...

- 100% of 270 diesel passenger vehicles type-approved at Euro 6d-temp have real-world-driving NOx emissions below RDE regulated levels (0.168 g/km), and many have near-zero NOx emissions, based on ACEA testing. Testing by ADAC reveals the some Euro 6d-Temp diesel cars have near zero NOx emissions in real-world testing, and one (MB C220d) has no measurable NOx emissions ( https://www.adac.de/rund-ums-fahrzeug/abgas-diesel-fahrverbote/abgasnorm/rde-messungen-cf-faktor/?redirectId=quer.rde%20messung ).

- PN measurements by Emissions Analytics shows newest diesel engines clean the air of particles (https://www.emissionsanalytics.com/news/2020/1/28/tyres-not-tailpipe).

- All 2018+ diesel passenger vehicles real-world tested by Emissions Analytics have CO emissions <0.125 g/km. That's >75% below the diesel Euro 6 standard (0.5 g/km), and almost 90% below the petrol Euro 6 standard (1.0 g/km). None of the 500+ diesels tested have failed to meet the Euro 6 diesel standard, regardless of model year. Meanwhile, several Euro 6 petrol vehicles failed to meet the 1.0 g/km petrol standard.

- The Advanced Collaborative Emissions Study (ACES), Phase 2, measured zero NMHC (VOC) emissions from U.S. 2010-compliant diesel truck engines under various test cycles. ACES 2 also revealed that over 300 unregulated emissions were 90%-100% below those measured from 2004 diesel truck engines (NiroPAH, Hopenes & Sterenes, Carbonyls, Metals & Elements, Elemental carbon, Dioxin & Furans were all reduced 100%, i.e., these emissions were not detected).

- A recent European Environmental Agency report concludes that passenger vehicles' GHG emissions in 2017 in Europe increased for the first time since monitoring started in 2010, thanks in part to the increased market share of petrol vehicles at the expense of decreased market share of diesel passenger vehicles. Petrol passenger vehicles produce 10% to 40% more GHG emissions than comparable diesel vehicles according to that report.

- Based on EPA in-use testing, 2019 Ram 1500 4X2 diesel pickup truck had no measurable THC, NMHC, CO, NOx, or PM exhaust emissions as tested on the HWY cycle by EPA itself. The 2020 Chevrolet Colorado 4X2 diesel pickup had <0.002 g/mi NMHC, <0.05 g/mi CO, <0.020 g/mi NOx (SULEV II = 0.020 g/mi), <0.0001 g/mi PM per EPA in-use testing in FTP and HWY test duty cycles.

How clean do diesel vehicles have to be before this demonization of diesel ICEV technology stops?
