This document discusses the Canadian chemical industry and its efforts to reduce greenhouse gas emissions over the past few decades. It notes that the Canadian Chemical Producers' Association has been tracking emissions since 1992 and urged members to reduce emissions in 1994, before the Kyoto Protocol. Several chemical companies have significantly reduced their emissions through improved energy efficiency and innovative processes. However, the industry now faces challenges from high and volatile natural gas prices in North America, which make the industry less competitive globally and have led to some plant closures. The chemical industry argues it adds significant value to natural resources by transforming them into many important products.
