Zero Waste UNEP UN-Habitat

The world is wasting food on a staggering scale.

Each year, humanity generates between 2.1 and 2.3 billion tonnes of municipal solid waste, squandering valuable resources that could be returned to our economy to reduce the demand for new virgin materials.

Waste pollution harms well-being and economies, and fuels climate change and biodiversity loss.

The International Day of Zero Waste champions and mobilizes efforts at all levels to promote zero-waste solutions and advance sustainable development.
