The Montreal Protocol shows what is possible when science, diplomacy, and business cooperate to implement international environmental agreements.

Global environmental problems are some of the most pressing issues that humanity is facing. There are few examples of success at resolving them; the fight to protect the ozone layer is one of them.

This publication is a collection of stories that celebrate the changing face of industry, reflecting on how the efforts supported by UNIDO to improve the environmental performance of the productive sector, have brought about sustainable solutions to other global challenges.

The demand of active cooling systems such as air conditioners and chillers is increasing rapidly. This leads to an increase in emissions of Chlorofluorocarbons (CFC) and Hydro-Chlorofluorocarbons (HCFC), which negatively impact the Earth's ozone layer.

The pre-monsoon cyclone Viyaru in the Bay of Bengal during May 2013 traversed a long track from 5°N to 22°N over 7 days with basin-wide response, which was well captured by the time series observations of OMNI buoy network along with satellite data.

The European Union (EU) has achieved its goals to phase out ozone-depleting substances under the Montreal Protocol. A new European Environment Agency (EEA) report shows that in 2018 the EU again destroyed or exported more ozone-depleting substances than it produced or imported.

We use 2010–2015 observations of atmospheric methane columns from the GOSAT satellite instrument in a global inverse analysis to improve estimates of methane emissions and their trends over the period, as well as the global concentration of tropospheric OH (the hydroxyl radical, methane's main sink) and its trend. Our inversion s

Clouds strongly modulate regional radiation balance and their evolution is profoundly influenced by circulations. This study uses 2001–16 satellite and reanalysis data together with regional model simulations to investigate the spring shortwave cloud radiative effect (SWCRE) and the associated circulations over so

Industries in north-eastern China have released large quantities of an ozone-depleting gas into the atmosphere in violation of an international treaty, scientists have said.

Japan’s weather bureau on Wednesday said the El Nino weather pattern appeared to be continuing, with an 80 percent chance it would stretch into the northern hemisphere summer.
