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.

Climate change continued its relentless march in 2020, which is on track to be one of the three warmest years on record. 2011-2020 will be the warmest decade on record, with the warmest six years all being since 2015, according to the World Meteorological Organization.

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 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.

Ozone pollution has increased in Delhi-NCR this summer compared to last year, an analysis by the Centre for Science and Environment, Delhi, has found.

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.

Union Environment Minister released the India Cooling Action Plan (ICAP) that seeks to provide an integrated approach towards cooling and related areas including reduction in the cooling demand, in order to reduce emissions.

The Assessment documents the advances in scientific understanding of ozone depletion reflecting the thinking of the many international scientific experts who have contributed to its preparation and review. These advances add to the scientific basis for decisions made by the Parties to the Montreal Protocol.
