Stratospheric ozone (O3) losses and consequent increases in surface ultraviolet (UV) radiation remain a health concern due to close association with skin cancers and cataracts. This study estimated how emissions of ozone‐depleting substances (ODS) affect, via O3 reductions, surface UV radiation and associated health impacts in Australia compared to the United States. We used climatological atmospheric data and the U.S. Environmental Protection Agency's Atmospheric Health Effects Framework (AHEF) model to estimate these effects for historic and projected ODS emissions.

Sir/Madam,

The Ozone Secretariat is pleased to attach herein, for your kind attention, a letter from the Executive Secretary on the General Trust Fund for Financing Activities on Research and Systematic Observations Relevant to the Vienna Convention: Call for project proposals.

Kindly note that the translated versions of this letter in French and Spanish will be sent to the relevant parties in due course.

Please accept, Sir/Madam, the assurances of my highest consideration.

TheMontreal Protocol on Substances thatDeplete theOzone Layer has greatly restricted the global production and consumption of long-lived ozonedepleting substances (ODS).However,ODS used or consumed as feedstocks in the manufacture of other chemicals are excluded from restrictions. This exclusion was based on the assumption that emission rates of feedstocks were only 0.5% of the amount produced and that feedstock production would decline in the future, with remaining emissions too small to significantly affect the stratospheric ozone or its recovery. In sharp contrast, feedstock emissions are now assessed as being substantially higher (typically 3.6% of production), and feedstock production and use has been rising rather than falling.
