Since GHG emissions come from a variety of sources throughout the US economy, it only follows that climate change mitigation will likewise depend on a variety of technologies and solutions. For instance, in the electricity sector –which researchers estimate contributes about one-third of all national GHG emissions – GHG emission reductions could arise from strategies, such as the development of renewable sources, improving efficiencies, and lessening demand. By contrast, in the industrial sector, GHG emissions can be reduced by new technologies that impact industrial processes, such as steel and cement production.
