#EllasLaw | Second reading of @GreenJennyJones's #CleanAirHRBill in @UKHouseofLords from 10am Friday 8 July HT @EllaRobertaFdn. It's about the #HumanRight to #CleanAir and meeting new @WHO guidelines asap. Follow this thread for live updates. Details here: cleanair.london/ellaslaw/
#EllasLaw | Ella Roberta Adoo Kissi-Debrah died tragically - aged nine - on 15 February 2013. #AirPollution was listed as one of the medical causes of death after a long campaign by her mother @EllaRobertaFdn won a second inquest cleanair.london/hot-topics/ell…
#EllasLaw | Coroner's 'Report to Prevent Future Deaths' said:

"@WHO guidelines should be seen as minimum requirements. Legally binding targets based on @WHO guidelines would reduce the number of deaths from air pollution in the UK"

@GreenJennyJones' #CleanAirHRBill does it!
