Certain sectors of the economy have characteristics that make them more amenable to early action – for example, those sectors which own major plant (e.g. plant that has substantial emissions from a single site) and are dominated by large organisations with access to substantial funds for investment, and which are subject to central regulation. These sectors may be able to address the challenge of deep reductions in emissions by modifying their plant or by substituting a different type of plant. Such changes may not be easy but these industries have the tools to make the changes if required.
