The climate crisis demands action — and action is happening. This archive tracks real progress: policy wins, clean-energy milestones, community resilience, and scientific advances that show meaningful change is possible. Stories here come from every corner of the world.
Finland’s carbon tax, introduced in January 1990, was the first of its kind anywhere in the world. It started modestly at about €1.12 per tonne of CO₂, more a proof of concept than a heavy lever. Sweden followed the next year, and the idea gradually reshaped how governments think about pricing pollution.
The Montreal Protocol was signed on 16 September 1987, when diplomats from dozens of nations agreed to phase out the chemicals eating a hole in the ozone layer. It became the first UN treaty ever ratified by every country on Earth, and scientists now expect the ozone layer to fully recover by around 2040.
The world’s first wind farm spun to life in late 1980 on a New Hampshire hillside, where 20 small turbines fed electricity directly into the grid. Blades broke, towers stood just 60 feet tall, and the project was quietly dismantled within a couple of years. But the proof held, and a direct line runs from those struggling machines to today’s global wind industry.
Yasuní National Park was established in 1979, when Ecuador drew a boundary around roughly 10,000 square kilometers of Amazonian rainforest where the equator, Andes, and Amazon converge. A single hectare there holds more insect species than all of North America. The park remains home to the Huaorani and two uncontacted peoples who have lived there for generations.
Sweden’s CFC aerosol ban, announced on January 23, 1978, made it the first country to prohibit the ozone-destroying propellants — acting seven years before scientists discovered the Antarctic ozone hole. The decision rested on theory alone, and it helped set the template for the Montreal Protocol and one of humanity’s rare universal environmental agreements.
