Maine is exceeding its emissions reduction goals, according to a new report from the state Department of Environmental Protection. The agency said Maine has reduced greenhouse gas emissions even as economic output increases.
As of 2021, Maine’s greenhouse gas emissions had fallen 30 percent below 1990 levels, according to the Department of Environmental Protection’s latest biennial emissions inventory released Tuesday. That puts the state ahead of schedule toward its goal of an 80 percent reduction by 2050, if current trends continue.
The department’s Stacy Knapp said the reductions indicate that Maine’s economy is transitioning to cleaner fuels, more efficient technology, and less carbon intensive industries.
“The point here is that Maine’s GDP continues to grow steadily, while at the same time, at least since the peak in 2002, our gross greenhouse gas emissions are decreasing,” she said.
Knapp said much of the emissions reduction can be linked to a decrease in petroleum fuel consumption. Maine’s overall energy consumption is also trending downward, according to the report.
And when accounting for the amount of carbon dioxide soaked up by the state’s forests, Knapp said Maine is close to achieving carbon neutrality — in other words, absorbing as much greenhouse gases as it emits.
“We are 91 percent percent of the way there,” Knapp said. “We are so close we can almost taste it.”
Knapp said that most of the state’s emissions still come from burning fossil fuels.
In recent years, Maine’s natural gas consumption has actually increased, largely to make up for reduced hydropower.
Transportation remains the state’s most polluting sector, according to the report, far outpacing emissions from residential, commercial and industrial uses. While emissions from the transportation sector have fallen slightly since 1990, they remain stubbornly high.
Knapp said while the big picture findings are encouraging, recent trends will need to continue for the state to achieve its long-term goals.
