If we reduce our Footprint from driving by 50% around the world and assume one-third of car miles are replaced by public transportation and the rest by biking and walking, Earth Overshoot Day would move back 11.5 days.
The global campaign for sustainability will be won, or lost, in cities.
Between 70% and 80% of all people are expected to live in urban areas by 2050.
Consequently, smart city planning and urban development strategies are instrumental to making sure there is enough natural capital and to avoid excessive human demand that would erode it. Examples include energy-efficient buildings, integrated zoning, compact cities, and effective options for people-powered and public transportation.
UN Sustainable Development Goal 11 Sustainable Cities and Communities features several 2030 targets, including:
- reduce the adverse per capita environmental impact of cities.
- provide access to safe, affordable, accessible and sustainable transport systems for all, notably by expanding public transport.
- enhance inclusive and sustainable urbanization and capacity for participatory, integrated and sustainable human settlement planning and management in all countries.
To be sustainable, development ultimately must also fit within our planet’s resource budget.
In particular, city planning can play a major role in shaping our need for cars. It matters because personal mobility makes up 17% of humanity’s carbon Footprint.
