France, Italy and the Czech Republic are among eight countries pushing to weaken new EU emissions limits for cars, saying they are overly ambitious and unrealistic for automakers to hit. European Union countries and lawmakers are preparing to negotiate the Euro 7 regulation, which from 2025 would tighten vehicle emission limits for pollutants including nitrogen oxides and carbon monoxide. In a joint paper, sent to other EU members and seen by Reuters, the eight countries said parts of the law, including curbs on exhaust pipe emissions, should be scrapped entirely.
