What are the steps of ozone depletion?
- ODS released into atmosphere. 2. ODS drift to stratosphere. 3. UV radiation breaks down ODS, releasing chlorine/bromine. 4. Chlorine/bromine destroy ozone molecules.
What is the purpose of the Montreal Protocol?
International treaty to phase out the production and consumption of ozone-depleting substances (ODS).
What is the purpose of the Clean Air Act (USA)?
Federal law regulating ODS production and use, setting limits and phase-out requirements in the USA.
What is the purpose of the EU Regulation on ODS?
Sets limits on ODS within European Union member states, similar to the Clean Air Act in the USA.
How does reducing ODS consumption help?
Lowers the amount of ozone-depleting chemicals released into the atmosphere.
How does supporting ODS phase-out help?
Encourages policies that ban ODS and promotes ozone-friendly alternatives.
How does energy efficiency mitigate ozone depletion?
Reduces fossil fuel use, indirectly lowering ODS emissions.
