Speakers at the Clean Air Summit, held at City Hall yesterday, have called on the government to increase its efforts to ensure the UK has one hundred percent clean air by 2030.

Attendees of the conference, which included London Mayor Sadiq Kahn, business leaders, local politicians and members of the scientific community, have warned that failing to meet World Health Organisation (WHO) air quality targets will prolong a public health crisis, brought on by air pollution.

The environmental campaign group UK100, who organised the event, have also asked for an increase in council funding and autonomy for local initiatives designed to curb air pollution and climate change.

UK100 director, Polly Billington, speaking outside City Hall said, “nobody can escape the climate crisis so everybody needs to be able to act, but solutions will need to be designed around communities.”

One London community which has already declared a climate emergency is Hackney.

Cllr Jon Burke, the council’s leading environmental spokesman, claims his borough is leading the capital’s charge against climate change and air pollution.

Indeed, Hackney’s Homerton Hospital has cut its emissions by 15% in the last two years, and in the process retained its ‘Planet Mark’ status – a national award recognising hospitals which have reduced their annual emissions by 5% or more.

Hackney Council have also set a target of 45% decarbonisation by 2030 and Cllr Burke has pledged to reduce private vehicle ownership 25pc by the same year.
