Carlos Moreno

Moreno proposed measuring the city in time rather than in area. If work, school, shopping, the doctor and leisure are fifteen minutes away on foot or by bike, a large share of compulsory journeys disappears, and with them congestion, emissions and lost hours.

Paris adopted it as a government programme and from there it spread to dozens of cities. It has also drawn two serious criticisms worth knowing: that it can make the neighbourhoods that achieve it more expensive, and that without affordable housing it becomes a privilege rather than a right.
