The Circular Economy
How rethinking production and consumption -- from 'take-make-waste' to circular systems -- could reduce emissions and resource depletion.
From Linear to Circular
The modern economy operates on a linear model: extract raw materials, manufacture products, use them, and discard them as waste. This 'take-make-waste' system generates roughly 2 billion tonnes of municipal solid waste annually, and the material extraction it requires accounts for roughly half of global greenhouse gas emissions when including processing and manufacturing.
The circular economy offers an alternative: design products for longevity, reuse, repair, and recycling so that materials circulate within the economy rather than flowing to landfills. The Ellen MacArthur Foundation, a leading proponent, estimates that circular strategies in key sectors -- cement, steel, plastics, aluminum, food -- could reduce global emissions by 9.3 billion tonnes per year by 2050, roughly 40% of the reduction needed.
