Cities only cover 2% of the world’s land surface, but activities within their boundaries consume over 75% of the planet’s material resources.

With the expansion of urban areas, the world’s material consumption is expected to grow from 41.1 billion tonnes in 2010 to about 89 billion tonnes by 2050.

In today’s graphic, we use data from the UN International Resource Panel to visualize the material impact of global urbanization.

How Material Consumption is Calculated

Today, more than 4.3 billion people or 55% of the world’s population live in urban settings, and the number is expected to rise to 80% by 2050.

Every year, the world produces an immense amount of materials in order to supply the continuous construction of human-built environments.

To calculate how much we use to build our cities, the UN uses the Domestic Material Consumption (DMC), a measure of all raw materials extracted from the domestic territory per year, plus all physical imports, minus all physical exports.

Generally, the material consumption is highly uneven across the different world regions. In terms of material footprint, the world’s wealthiest countries consume 10 times as much as the poorest and twice the global average.

Based on the total urban DMC, Eastern Asia leads the world (Read more...)
