REPORT

Key takeaways:

• Efforts to put a price on greenhouse gas emissions are growing, with carbon prices now in effect in all Canadian provinces as well as 12 U.S. states.
• Several North American carbon-pricing programs have been in effect for more than a decade. Evaluations show they have reduced energy use and emissions while also providing other benefits, including perhaps helping local economies (and certainly not appreciably harming them).
• While a price on carbon is an important strategy, to achieve long-term carbon-reduction goals, carbon pricing will need to be complemented by other approaches to reducing energy use and emissions.
