Headlines successful the tally up to Cop26 person promised caller technologies, including electric cars, flying taxis and heat pumps to lukewarm our homes. But we tin bash much – starting with the streets astir us.

Jon Burke, a decarbonisation argumentation consultant, has likened the backstage centrifugal conveyance to an invasive species. It grows to dominate our transport systems, choking retired alternatives, and erodes the divers societal cloth of neighbourhoods. While electrical vehicles volition trim climate-changing emissions and exhaust pollution, they volition not relieve our congested roads and volition not tackle air contamination from tyres, brakes and roadworthy wear.

Redesigning our villages, towns and cities to favour walking and cycling tin assistance the climate crisis, aerial contamination and the municipality noise that plagues the lives of truthful galore people, arsenic good arsenic improving our wellness done regular exercise. This goes beyond debates connected rhythm lanes and low-traffic neighbourhoods. Cities astir the globe including Sydney, Portland, Paris and present galore successful China, are embracing the “15-minute city”. This places shops, schools, wellness centres and the mundane necessities of beingness wrong an casual walk, rhythm oregon nationalist transport trip, reducing the request for car usage and location deliveries.

A study from Barcelona’s Institute for Global Health adds to grounds connected the benefits from reclaiming the municipality abstraction devoted to traffic.

Much-quoted probe from the 1980s recovered that betterment from country could beryllium helped simply by seeing trees from the infirmary window. More caller studies person recovered that people unrecorded longer and person fewer bosom problems if they person greenish spaces successful their neighbourhoods. The World Health Organization (WHO) truthful recommends that we person entree to 0.5 hectares of nationalist greenish space – astir two-thirds of a shot pitch – wrong 300 metres of our homes.

The Barcelona researchers looked astatine outer images of much than 1,000 European cities. They recovered that 62% of radical were surviving successful areas with little greenish abstraction than recommended. Meeting the WHO recommendations could forestall 43,000 aboriginal deaths a twelvemonth crossed 31 European countries studied.

Mark Nieuwenhuijsen, who led the research, said: “Any greenery that tin beryllium introduced is good: greenish roofs and vertical gardens, greenish schoolhouse yards, greenish corridors, thoroughfare trees, parkland and pouch parks, assemblage gardens and different measures specified arsenic rerouting traffic, digging up asphalt and replacing it with greenish space, crossed the board.”

Globally more than 50% of radical unrecorded successful cities. In the UK it is 80%. Pathways towards healthy, low-pollution and low-carbon cities should beryllium a precedence for the forthcoming Cop26.
