Climate change: Future international action
NZ commitment under the Kyoto Protocol
– key issues for consideration
from the perspective of the Montreal Protocol
Janet F. Bornman, International Global Change Institute, IGCI University of Waikato
UNEP: Environmental Effects Assessment Panel, EEAP
Co-chairs: Janet F. Bornman, Xiaoyan Tang, Jan van der Leun
Assessment of effects of O3 depletion & climate change interaction on:Ozone and UV changes – Health – Terrestrial ecosystemsAquatic ecosystems – Biogeochemical cycles Air Quality – Materials
1974: emissions of CFCs (chlorofluorocarbons) were depleting the stratospheric ozone layer
1980s: thinning of the ozone layer over Antarctica
- “ozone hole”
Thinning has occurred over every continent
1987: production of controlled ODS
- more than 1.8 million tonnes/year
2005: - reduced to 83,000 tonnes
16 September 1987
24 countries signed the initial MP on substances that deplete the ozone layer
Today, twenty years later
191 countries have ratified the MP
-committed to meeting strict time-bound reduction obligations for each of the ca 100 substances controlled by the Protocol
Today: 95% reduction achieved
The work of the MP is not yet finished
Predictions for full recovery to pre-1980 levels rely on assumptions of full implementation of the MP
“The Montreal Protocol is working. The concentrations of ozone depleting substances in the atmosphere are now decreasing”
beyond 2012 learn from the MP?
Assessment panels on science, environmental effects, technology and economic issues
- independent assessments
- Responding also to specific inquiries by the MP Parties
Since 1990, provided support to developing countries to enable them to meet their reduction obligations under the Protocol
Not often thought of as a partner!
Includes an Implementation Committee
- works together with countries facing difficulties to manage action plans with time specific benchmarks for helping countries come into compliance with the MP
Definite deadlines for developed and developing countries
Allowance for ”critical use exemptions”, but with time limits
The Montreal ProtocolKyoto Protocolis working. The concentrations of CO2 ozone depleting substances in the atmosphere are now decreasing
