This flexibility meant that the protocol could be modified to introduce stricter controls: more ozone-depleting substances added to the checklist and requiring a full exit instead of a partial exit. The modest start-up also fostered greater confidence in the process. 1.116 Two of the four areas were unable to provide documentation of conservation outcomes. The other two sites provided results on the dynamics of major animal and vegetation populations and on the state of wetland habitats. One of these sites recently compiled its results information to identify gaps and guide the future update of its management plan. The Montreal Protocol also provided a stable framework for industry to plan for research and innovation over the long term. It was a happy coincidence that there are benefits for the industry to turn away from the ODS. CFCs were old, well-patented technologies. The shift to newer, cheap formulations, with less potential or non-depleting potential for the ozone layer, has benefited the environment and industry. In November 1982, the secretariat of the United Nations Environment Programme drafted a document for the ad hoc working group of legal and technical experts for the development of a Global Framework Convention for the Protection of the Ozone Layer, which sets out alternative structures for protocols or annexes to the draft convention (UNEP/WG.78/11).
Subsequently, Finland, Norway and Sweden presented a draft annex on control measures, limiting and reducing the use and emissions of hydrochlorofluorocarbons to protect the ozone layer (UNEP/WG.94/4), which, in its revised version, has accepted the codification of the proposed control measures as a protocol and not in an annex as previously planned (UNEP/WG.94/5, p. 9 and 41). A revised text of the draft protocol was therefore submitted to the ad hoc working group (UNEP/WG.94/9). The draft protocol was re-revised at subsequent meetings of the ad hoc working group (UNEP/WG.94/12, WG.110/CRP.1 and UNEP/IG.53/4, Appendix III). 1.48 What we looked at. We examined whether Environment Canada knew how well Canada would achieve the estimated reduction in NOx and VOC emissions, as indicated in the Ozone Annex. In addition, we reviewed related information on Canada`s environmental impact or the results of emissions reductions. 1.78 Recommendation. Transport Canada should define environmental performance and meet the expectations that marine oil pollution prevention and monitoring programs can reasonably meet.
