Volkswagen has admitted to cheating on emissions tests of some of its diesel vehicles. The full story has not yet been made public, but Volkswagen seems not to be an isolated case. There are indications of widespread gaming of emissions testing in the European automobile industry, with regulators and governments turning a blind eye to cheats and being reluctant to introduce testing procedures that would measure actual emissions in real-world conditions.
There are some parallels with the estimation of emissions in the natural gas industry in British Columbia, where officially-sanctioned emissions rates are far lower than in other jurisdictions, compliance inspections are non-existent and methodologies do not include state-of-the art field measurements.
