Since becoming an implementing agency of the Multilateral Fund for the Implementation of the Montreal Protocol in 1992, UNIDO has completed around 1,400 projects to phase-out ozone-depleting substances in developing countries and economies in transition.
As a recipient of 20% of the budget of the Multilateral Fund, UNIDO has received US$849m to prepare and appraise investment project proposals and implement phase-out schedules at plant level.
UNIDO’s Montreal Protocol projects have helped phase out the use of more than a third of the consumption of ozone-depleting substances in the developing world. As a result, ozone levels began to recover in the 2000s. Now, the ozone hole is expected to reach pre-1980 levels by around 2075. The Montreal Protocol is considered the most successful international environmental agreement ever.
Fighting global warming
But the Montreal Protocol is not just saving the ozone layer. It is also a significant force against climate change, because many ozone-depleting substances also contribute to global warming.
By eliminating these substances, UNIDO has helped avoid the use and potential emission of 338 million tonnes of CO₂-equivalent per year as of 2015. This is equivalent to the CO₂ emissions of 99 coal-fired power plants or the CO₂ emissions of 71 million passenger cars driven in one year. To get an idea of the significance of this, think of Brazil where there are around 71 million cars on the road.
