An inhaler that costs nearly $300 in the US goes for just $9 in Germany. What gives?

The US Senate voted to ratify the Kigali Amendment, agreeing on a bipartisan vote to phase down climate-warming HFCs. Now what?
Representatives of 175 countries voted to start developing a global treaty to reduce plastic waste. Treaties addressing mercury, long-range air pollution and ozone depletion offer some lessons.
HFCs keep refrigerators cool, but when these short-lived climate pollutants leak, they warm the planet.
When the current crisis passes, we must seize the opportunity to re-imagine, and to create, a different kind of future.
New research finds that chlorofluorocarbons (CFCs) and other ozone-depleting substances have boosted the effects of climate change in the Arctic.
Measurements and modelling have found nitrous oxide emissions, a greenhouse gas 265 times more potent than carbon dioxide, are significantly higher than previously reported.
For several years, emissions of CFCs have been rising, in apparent defiance of a global ban in place since 2010. A new global detective effort has traced the source to two eastern Chinese provinces.
Almost 30 years ago the world responded to the realisation that our ozone layer was in trouble. The resulting Montreal Protocol was a rare example of global cooperation, but there’s no room for complacency.
