Executive summary of the World Meteorological Organization's 1994 "My assessment is from reading people like Fred Singer," he said. The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970, Crutzen first showed that nitrogen Environmental effects of ozone depletion: 1998 assessment Introduction The Montreal Protocol on Substances that Deplete the Ozone Layer requires periodic assessments of available scientific, environmental, technical and economic information. The assessments shall be made at least every four years. Assessments were made in 1989, 1991, 1994, and A Guide to Life Cycle Assessment of Buildings 9 Executive Summary: The Future of Building Life Cycle Assessment in Practice Summary As the architectural and construction industries increasingly emphasize sustainability, more comprehensive methods are being developed to evaluate and reduce environmental impacts buildings.
