1991 UNEP Flexible and Rigid Foams Technical Options Report: Pursuant to Article (6) of the Montreal Protocol on Substances that Deplete the Ozone Layer under the Auspices of the United Nations Environment Programme - Final

This report offers a structured analysis by the Flexible and Rigid Foams Technical Options Committee under the Montreal Protocol framework. It evaluates the global consumption of chlorofluorocarbons (CFCs) in foam plastics, particularly in sectors such as building and appliance insulation, packaging, and cushioning. The document thoroughly investigates alternative technologies and blowing agents, such as HCFCs, HFCs, hydrocarbons, and carbon dioxide, identifying viable short-term and long-term replacements. It outlines technical challenges including toxicity, flammability, insulation efficiency, and environmental impact, and emphasizes the need for regulatory and economic alignment, especially in developing countries. The report reflects on progress made since 1986, forecasting that a near-total phaseout of CFCs is technically feasible by 1995, provided transitional alternatives are available. It also highlights regional disparities in technology adoption and recommends structured government-industry collaboration to ensure an efficient and sustainable transition away from ozone-depleting substances.
