Environment Statistics

By end of 2023 the world had 1,530 gigawatts of renewable power, yet air pollution still drives millions of deaths and only 9% of plastic packaging is recycled worldwide. This page connects the energy and climate transition with the impacts on health and materials so you can see where progress is fast, where it is stalled, and what is likely to follow.

Global CO2 emissions reached 51.9 gigatons in 2023 while renewable power capacity climbed to 1,530 gigawatts by the end of that same year. Air pollution remains a parallel crisis with WHO estimating that 99% of the world’s population breathes air above PM2.5 guideline limits in 2019. This post brings those tensions together through key environment statistics so you can see what is accelerating, what is stalling, and where policy and technology are making measurable differences.
