In 1987, the world came together to tackle one of the greatest environmental challenges of our time: the depletion of the Earth’s ozone layer. United by a shared goal, 197 nations, both big and small, developed and developing, enacted the Montreal Protocol, rewriting history.

The groundbreaking treaty, which called on all countries to phase out the production and consumption of ozone-depleting substances (ODS), required firm international commitment, stepwise progress, and steady leadership. To pave the way, the Multilateral Fund (MLF) was established in 1991 to assist developing countries in meeting their Montreal Protocol obligations through strategic project investments, technical guidance and capacity building.

For over 30 years, MLF has led developing nations - and the world - in the transition away from ODS, and more recently, hydrofluorocarbons (HFCs). This effort has not only protected the ozone layer but also significantly curbed greenhouse gases contributing to global warming. By amplifying its positive impact, MLF is driving progress on Sustainable Development Goals (SDGs) ranging from climate action and sustainable innovation to human well-being and gender equality.

In solidarity with its international partners, MLF is steering both people and the planet toward a safer, healthier, and more prosperous future.

Replenishment

The Multilateral Fund is replenished every three years with a decision taken by the Meeting of the Parties to the Montreal Protocol. Parties agree on the level of replenishment for the Fund based on a report by the Technology and Economic Assessment Panel which assesses the needs of the developing countries to comply with the obligations under the Montreal Protocol. The Panel was established in 1990 as the technology and economics advisory body to the Montreal Protocol parties.
