pollution

ML models are combining data from satellites, low-cost sensors, and weather systems to produce real-time air quality maps far more detailed than official monitoring networks.

The United States generates more plastic waste per capita than any large nation — 130 kg per person per year. But the Philippines, Indonesia, and India contribute the most plastic to the ocean. How you rank countries on plastic pollution depends entirely on whether you measure production, per-capita waste, or ocean contribution.

The world generated 62 million tonnes of e-waste in 2022 — a record. China produces the most e-waste in absolute terms (12 million tonnes). Norway and Iceland generate the most per capita. Only 22% of e-waste is formally recycled. E-waste contains $62 billion in recoverable precious metals annually.

Air quality is one of the most direct indicators of environmental health. This ranking shows which countries and territories breathe the cleanest air, which suffer the worst pollution, and why small islands keep beating industrial giants on the numbers.
