Answer 1

Answer:

D. Montreal Protocol

• The original Montreal Protocol, signed in 1987, was the first step in international efforts to protect stratospheric ozone.
• The London Amendment (1990) changed the ozone-depleting substances emission schedule by requiring the complete phaseout of CFCs, halons, and carbon tetrachloride by 2000 in developed countries, and by 2010 in developing countries.
• Methyl chloroform was also added to the list of controlled ozone-depleting substances, with phaseout in developed countries targeted in 2005, and in 2015 for developing countries.
