Learning by climbing steps. Part of an Information Kit to assist developing countries to raise awareness on ozone depletion and protection, this publication shows ODS Officers how to plan focused efforts aimed at both the public and industry to help them be aware of ozone issues. A five-step planning cycle is presented, with specific examples of how each step should be done. Although this publication is intended mainly for National Ozone Units, it could also be useful to others who wish to initiate awareness raising activities on ozone depletion.
