‘There is also evidence linking air pollution with an increased vulnerability to the most severe impacts of COVID-19. This new data shows that the action I’m taking is already making a difference and saving lives. These figures prove without a doubt that the Low Emission Zone and Ultra Low Emission Zone are accelerating the shift to cleaner vehicles."

I cannot find the "new data shows that the action I’m taking is already making a 

difference and saving lives. ". Please can you send me the "new data" which shows the 

Mayor is "saving lives".
