Gov. Chris Christie pulled New Jersey out of the Regional Greenhouse Gas Initiative (RGGI) last month, a move opposed by environmentalists and Democratic lawmakers. They are pushing legislation to rejoin the 10-state coalition, which is designed to develop a regional approach to curbing greenhouse gas emissions from power plants through a cap-and-trade program. In a bid to bolster their effort, Environment New Jersey released a report yesterday citing the benefits of the program.

120 million: Amount of carbon dioxide emissions released by power plants in 10 states that are members of the coalition.

30th: Where RGGI states would rank among nations in terms of amount of carbon dioxide emissions.

$1.89: Current floor-price per ton for carbon dioxide allowances.

$872 million: What has been raised for the states in 11 auctions held so far.

$440 million: What the states have invested in energy efficiency projects using proceeds from the auctions.

$2.6 billion: Estimated increase in gross state product (the total output of a state's economy) in member states through spending of RGGI funds.

$209.9 million: Estimated increase in gross state product in New Jersey through spending of RGGI funds.

184 million: The peak in carbon dioxide emissions in tons by the 10 states, which occurred in 2005.

$35 million: Total amount of money invested in clean energy in New Jersey from RGGI funds.

$90 million: Estimated energy savings in New Jersey through money spent on energy efficiency.

2 percent: What power plants in RGGI contribute to the national total of greenhouse gas emissions.
