Environmental advocates are open to settling a case over the Climate Act, claiming that an October ruling from a state Supreme Court justice has caused energy costs to rise if the state Legislature does not extend the greenhouse gas reduction deadlines of New York's Climate Act. The ruling, which states that the Department of Environmental Conservation must comply with a statutory mandate to put forth rules to ensure New York reaches its targets of achieving a 40% reduction in greenhouse gas emissions by 2030, is pending appeal by New York Attorney General Letitia James. The state Energy Research and Development Authority has stated that to bring emissions down enough to meet the 2030 requirements of the climate Act, the state would need to implement a highly costly version of a cap-and-invest program. This program would place a price on carbon emissions and allocate funds to heavy industry, which heavy industry pays an additional amount to operate. However, there is no limit on how much it would cost to emit a ton of carbon, leaving fossil fuels like natural gas and gasoline very expensive.
