A recent study published in Nature confirms that natural gas alone is not a bridge to reducing greenhouse gas emissions. The study finds that, “in the absence of new climate policies, increased supplies of natural gas may have little effect on CO2 emissions and could actually delay decarbonization of the global energy system.” An abundant supply of low cost natural gas competes with and replaces not only dirtier fuels, like coal and oil, but also cleaner resources such as wind, solar and efficiency.
The Nature study used energy-economic modeling to compare a “conventional” gas supply with an abundant” supply scenario, and found that expanding natural gas supplies is not a climate panacea: “Whether the goal is avoiding CO2 emissions or hastening the transition to an emissions-free energy system, a global gas boom is not a replacement for energy and climate policies.”
Abundant gas entrenches us more deeply in a high-emissions, climate-compromised future, unless accompanied by robust, additional policies ensuring greater efficiency and a swift transition to low-carbon energy. CLF’s groundbreaking 2014 settlement with Footprint Power, a proposed natural gas-fired power plant sited on the grounds of a closed coal-fired plant in Salem, MA, included binding annual emissions limits and a fixed retirement date of no later than 2050. These conditions tamp down our reliance on natural gas and align plant operation with the timely decarbonization of our energy system..
The Nature study corroborates something CLF has long argued – without strong climate policy, gas is just a bridge to more gas.
