Countries have successfully reduced harmful atmospheric gases

Researchers have detected a significant decrease in hydrochlorofluorocarbons in the atmosphere, marking progress in global efforts to protect the ozone layer and mitigate climate change.

Sarah Kaplan reports for The Washington Post.

In short:

Atmospheric levels of hydrochlorofluorocarbons (HCFCs), harmful gases from air conditioning and refrigeration, have significantly dropped since peaking in 2021.
The decline follows the 1987 Montreal Protocol, which phased out ozone-depleting substances like HCFCs.
Researchers expect HCFC levels to return to 1980 levels by 2080, highlighting the success of international cooperation.

Key quote:

“This milestone is a testament to the power of international cooperation.”

— Avipsa Mahapatra, director of the Environmental Investigation Agency’s climate campaign

Why this matters:

Reducing HCFCs shows that coordinated global policies can effectively tackle environmental issues. This success offers hope and a model for addressing climate change challenges, which are crucial as greenhouse gas emissions continue to rise.
