Ralph Northam, has vowed to continue the process, although a separate proposal to link Virginia’s program with R.G.G.I. Economists have long argued that carbon pricing, either through a direct tax or cap-and-trade, can be an effective tool for reducing the greenhouse gas emissions warming the planet. states have fallen 40 percent since 2009 — faster than in the rest of the country — while electricity prices have declined 3.9 percent. Taken together, the states that either have or are considering carbon pricing accounted for roughly 21 percent of America’s carbon dioxide emissions in 2015.
