The 2014 UNEP Ozone Assessment Environmental Effects Assessment Panel of the Montreal Protocol An update 25th Meeting of the Parties to the Protocol Bangkok, Thailand EEAP Co-chairs Nigel Paul (Lancaster University, UK) Janet Bornman (Curtin University, Australia) Min Shao (Peking University, China) October 24, 2013 25th Meeting of the Parties, Bangkok 1
The Parties Request (Decision XXIII/13) Terms of reference for the 2013 EEAP report Effects of ultraviolet radiation reaching the biosphere and how those effects relate to physical, biological and environmental processes. Adverse effects of ultraviolet radiation on human health, including cancers, eye damage, infectious and other diseases and the beneficial effects of ultraviolet radiation. Effects on the biodiversity and functioning of ecosystems, including the delivery of ecosystem services such as food production. Effects of ultraviolet radiation on materials, including materials used in building construction. Risks to human health and the environment from substances that affect the ozone layer. a) b) c) d) e) October 24, 2013 25th Meeting of the Parties, Bangkok 2

2014 Contents: The Birds-Eye View Key ongoing issues Quantitative relationships between change in ozone change, and change in UV radiation as it affects humans and ecosystems Balance of contrasting effects, within organisms (e.g. positive and negative effects of UV on human health), and ecosystems. What is new in science Improved understanding of the fundamental mechanisms of responses. Interactions with other elements of environmental change Key requests from the Parties to the Protocol October 24, 2013 25th Meeting of the Parties, Bangkok 4
