Germany finds truckers cheating to hide emissions

German authorities have identified hundreds of trucks "manipulated" to save their operators money by shutting off exhaust treatment systems, saying many more cheating vehicles could be at large on Europe's roads.

Of around 13,000 trucks whose "AdBlue" filter system was checked on German roads last year, 300 were "defective", a government answer to a parliamentary question from the Greens party seen Tuesday by AFP showed.

Of 132 such defects spotted since August last year, 84 could be traced back to deliberate manipulation rather than a technical fault, the government added -- a distinction not drawn in statistics collected before then.

Electronic devices available for around 100 euros ($112) allow users to deactivate the exhaust treatment system, allowing some trucking firms to make massive savings, daily Sueddeutsche Zeitung (SZ) reported after revealing the scheme.

But with their catalytic converters switched off, the trucks spew far more harmful pollutants.

"The fact that we are finding more manipulated systems than faulty ones is an alarm signal," Greens MP Stephan Kuehn said.

With time, "the parts needed for the cheating are becoming smaller and smaller and more sophisticated, and therefore more difficult to find" during spot checks, the government added.

The SZ reported that operators can save up to one-third of the costs of running a truck supposedly meeting the Euro 5 or 6 emissions standard by installing one of the boxes or modifying software -- an even harder-to-detect option.

Devices or software changes can enable cheating in a number of ways.

Some fool the engine control software into thinking the catalytic converter is still working, preventing a warning to the driver or an automatic reduction in performance.

Others produce fake readings for the outside temperature, triggering a system that deactivates exhaust treatment at below -11 Celsius (12.2 Fahrenheit).

Clusters of similar rule-breaking have been identified elsewhere in Europe, especially in Spain.

Without exhaust treatment, trucks emit far more nitrogen oxides (NOx), which studies have shown is linked to various respiratory and cardiovascular diseases.

Since Volkswagen admitted in 2015 to cheating emissions tests on 11 million vehicles worldwide, alarm has spread in Germany about levels of the gas in city air.

Federal, state and local governments are battling to prevent drivers of older diesel vehicles being banned from city centres as courts order a growing number of exclusion zones.

Germany reports first greenhouse emissions fall in five years
Berlin (AFP) April 2, 2019 - Germany said Tuesday it had reduced emissions of greenhouse gases signficantly for the first time in five years in 2018, although it has already abandoned self-imposed targets for the end of this decade.

Europe's largest economy -- which is haltingly transitioning away from coal and nuclear to cleaner energy forms -- lowered output of the gases by 4.2 percent year-on-year, environment minister Svenja Schulze said in a report.

A helping hand came from the unusually mild weather, which reduced the need for heating.

But Germany also "drew more energy from wind and the sun and less from coal, oil and gas," Schulze said.

It also achieved a slight reduction in emissions from transport.

In total, Germany pumped 868.7 million tonnes of greenhouse gases into the atmosphere, some 30.6 percent below levels in 1990 -- the year taken as a benchmark for its climate targets.

Last year, Chancellor Angela Merkel's fourth government officially gave up on the goal of slashing output by 40 percent by 2020.

Experts had long highlighted the goal as unachievable.

But Berlin still aims to cut greenhouse emissions by 55 percent by 2030 compared with 40 years before, with a long-term goal of zero net output by 2050.

"In the course of this year," minister Schulze aims to pass a far-reaching climate law with a "detailed road map" for energy production, taking into account a planned exit from coal power by 2038.

US investigating Kia, Hyundai over 'non-crash fires'
New York (AFP) April 2, 2019
US authorities said Monday that they have opened two separate investigations into automakers Kia and Hyundai after receiving more than 3,100 complaints of "non-crash fires" affecting vehicles from both manufacturers. The incidents are linked to one death and more than 100 injuries to date, according to the National Highway Traffic Safety Administration (NHTSA) road transport regulator. Nearly three million vehicles from the two manufacturers could be recalled after investigations that began on M ... read more
