Since taking office, Alberta Premier Rachel Notley has been very aggressive on the climate file. Attempting to remedy what she portrayed as a history of environmental negligence by her predecessors , the premier swiftly increased and expanded Alberta’s carbon tax, placed a hard cap on carbon dioxide emissions, set stiff targets for reducing methane emissions, declared an accelerated phase-out of coal power generation, and promised to replace much of that power with costlier wind or solar power generation.
