To cover this vast amount of ground, it discusses, at a high level, subjects ranging from observations of various parts of the climate system and climate modelling to the limits of economic assessments, the different pathways of greenhouse gas emissions considered, adaptation response strategies and methods of mitigation that include everything from from taxing greenhouse gas emissions to removing carbon dioxide directly from the atmosphere.

WCA believes that the pathway to zero emissions from coal starts with the deployment of high efficiency low emission coal technologies (HELE) and progresses to carbon capture use and storage (CCUS).
