London Mayor's Office Accused of Trying to Silence Scientists Over Emissions Research

Private Correspondence Reveals Disappointment Over Findings

A controversy has erupted after it was revealed that London Mayor Sadiq Khan's office attempted to "silence" scientists who discovered that his ultra-low emission zone (ULEZ) had little impact on pollution. Private correspondence between his environment deputy Shirley Rodrigues and Imperial College Professor Frank Kelly showed that Rodrigues was "really disappointed" with the research findings.

ULEZ to be Expanded Across London

The ULEZ, which charges drivers £12.50 a day if their vehicle does not meet emissions standards, is set to be extended to cover all of London next week. However, a recent study by Imperial College found that the initial introduction of the ULEZ in 2019 resulted in a nitrogen oxide reduction of less than three percent.

Scientists Pressured to Issue Statement Contradicting Research

Despite the findings, Prof Kelly agreed to issue a statement, with the help of Rodrigues, claiming that the ULEZ had helped "dramatically to reduce air pollution." However, colleagues of Prof Kelly have expressed their full support for the original research, stating that they stand by it "100 percent".

Concerns Raised Over Relationship Between Mayor's Office and Scientists

Critics have raised concerns about an "alarmingly cosy relationship" between Mayor Khan's office and the scientists involved. Tory member of the Greater London Assembly, Peter Fortune, described the attempt to silence the scientists as "unacceptable". However, a spokesperson for Mayor Khan defended the collaboration, stating that it was "normal and proper" to work with experts to ensure the effectiveness of policies.
