Thriving lives within the means of our planet is not out of our reach. We see four major areas of opportunity for improving sustainability: food, cities, population, and energy.

How we meet one of our most basic need–food–is a powerful way to influence sustainability. Sourcing food locally and avoiding highly processed foods can lower the Ecological Footprint. Emphasizing plant-based diets and reducing animal protein can also have a major impact. Learn More

Eighty percent of the world population is expected to live in cities by 2050. Consequently, city planning and urban development strategies are instrumental to balancing the supply of natural capital and population’s demand. Examples include energy-efficient buildings and adequate public transportation. See how the Ecological Footprint approach is transforming Vancouver one neighborhood at a time.

Being committed to everyone living secure lives in a world of finite resources requires addressing population growth. Empowering women is essential for global sustainability. When women are respected as equal partners in the household and in the community, lower reproductive rates invariably ensue. Learn More

Decarbonizing the economy is our best possible chance to address climate change, and would improve the balance between our Ecological Footprint and the planet’s renewable natural resources. Per the 2015 Paris Accord on Climate, capping the global temperature rise at below 2°C implies keeping CO2e- atmospheric concentration below 450 parts per million (ppm). In 2016, the atmosphere contained 407 ppm CO2e-. The current carbon Footprint adds 2 ppm per year.
