Dieselgate: Use of defeat devices in car pollution control

This procedure examines the widespread use of 'defeat devices' in diesel vehicles, which were designed to cheat emissions tests. It focuses on how these devices reduce the effectiveness of pollution control systems during normal driving, leading to higher nitrogen oxide emissions than legally permitted.

This affects automotive manufacturers and vehicle owners. It aims to ensure stricter compliance with air quality standards and hold car makers accountable for misleading pollution data.
