Ozone Treaty Could Slow Climate Change
By Stephen Leahy
MONTREAL, Sep 17 (IPS) – Delegates from 191 nations are in Montreal, Canada this week to celebrate and extend the world’s most successful environmental treaty, the Montreal Protocol to protect the ozone layer.
With 95 percent of the target chemicals now eliminated, there is strong support to accelerate the phase-out of newer ozone-depleting chemicals that are also powerful greenhouses gases.
In fact, many experts believe this meeting could do more to reduce greenhouse emissions than the more widely-publicised Kyoto Protocol.
Challenges do remain — the United States continues to use large amounts of methyl bromide, an ozone-depleting substance (ODS), and the economic booms in China and India have rapidly increased the numbers of air conditioners using replacement chemicals.
