Ban diesel cars in London

IPPR analysis says capital will eventually need to phase out diesel cars and buses in order to meet EU air pollution 
targets

“London’s air is both lethal and illegal,” said Harry Quilter-Pinner, researcher at IPPR. “This is a public health crisis and it should be ignored no longer. Only bold action will make the capital’s air safe to breathe again.”

He added: “[Our] analysis suggests Khan will ultimately need to phase out diesel cars and buses in order to reach legal compliance.”

This would require the cooperation of national government, as the mayor lacks the power to achieve this result alone. The report, entitled Lethal and Illegal, found that under the current air pollution regime, London would fail to meet its legal requirements on air quality until 2025 or later.
