Sometimes people are surprised when the Circular Economy is mentioned in context of addressing our looming climate change problems.
Here  is a basic introduction to the answer.
I picked out these quotes:
"...the transition to renewable energy can only address 55% of emissions; the remaining 45% comes from producing..."
Although the exact percentages depend on complex measurements and so will vary - the key principle is vital.
"Today, the world produces over 2 billion tonnes of solid waste, and that’s expected to grow to 3.4 billion tonnes by 2050..."
The ways and amount we currently consume (esp in the richer countries) is a key underlying cause of climate change. And a regenerative Circular Economy offers a way to rethink that consumption.
