U.S Secretary of State John Kerry is expected to arrive in Rwanda today to join other more than 1,000 environmental protection delegates attending the ongoing 28th Meeting of the Parties to the Montreal Protocol.

Kerry will join in the discussions aimed at coming up with better legislation to ensure the protection of the ozone layer, particularly aiming to ensure the reduction of the use of hydrofluorocarbons (HFCs).

A successful amendment of the Montreal Protocol in Kigali would signal the world’s commitment to practical action towards achieving the goals of the Paris Agreement.

Once passed, the amendment would help the world avoid a 0.5°C global warming by the end of the century.

Experts also say that the passing of the amendment would help the world reduce the number of skin cancer cases by two million annually.

he Montreal Protocol on substances that deplete the ozone layer is widely regarded to be one of the most successful environmental treaties ever. It was the first treaty to achieve universal ratification.
