Support is mounting for California, Washington state and the Canadian province of Quebec linking their carbon markets into one system, which would create the biggest mandatory market in North America.
Several businesses and green groups backed the potential merger in letters to Washington, which asked for feedback as it seeks to link up with California and Quebec.
The letters show the high stakes of the potential merger.
“The decision whether to pursue linkage will have far reaching consequences” for Washington’s ability to achieve its legally mandated greenhouse gas emissions cuts, environmental group Washington Conservation Action said in its letter. “It may also have profound applications for carbon markets on a national and international scale.”
