IB ESS 6.4.8 Montreal Protocol
Practise using ozone data to judge how the Montreal Protocol reduced ODS use and supported the projected recovery of stratospheric ozone.
How this is tested
- use ozone graphs to identify predicted recovery dates and changes after 2020
- evaluate Protocol success using CFC phase-out, global cooperation and delayed recovery
- explain how bans, substitutes and financial support reduced ozone-depleting substances
