This document summarizes British Columbia's carbon tax, which was implemented in 2008 at $10 per tonne of CO2 emissions and increased steadily to $30 per tonne by 2012. The tax applies broadly and has raised billions in revenue, which has been returned to citizens. Analysis shows the tax has reduced emissions without harming the economy. While political and public support for the tax has grown, the next steps beyond maintaining the $30 per tonne rate are still under discussion, including potential increases and expansions recommended by an advisory panel. Key considerations for the future include affordability, competitiveness of industries, and lessons learned from the success so far.
