Hawaii is ahead most other states in accomplishing President Barack Obama's goals to cut carbon levels.
The Obama administration announced a plan Monday to cut carbon dioxide emissions from power plants by 30 percent by 2030.
Under the proposal, Hawaii would have to reduce its emissions rate by about 15 percent by 2030.
Hawaii has already embarked on an initiative to achieve 70 percent clean energy by 2030, with 30 percent from efficiency measures and 40 percent coming from locally generated renewable sources.
Most states tend to have higher rates of emissions from coal power plants and other fossil fuel sources.
Power plant emissions are the largest source of greenhouse gases in the country.
Hawaiian Electric Company issued a statement in response to the changes:
“At the Hawaiian Electric Companies, we’re very committed to reducing greenhouse gas emissions from electricity production in our islands. We support the goals of our nation’s environmental laws and have long been focused on achieving our state’s clean energy goals, which are among the most aggressive in the nation. We’re reviewing the EPA’s proposed rule to determine how they would apply to our specific situation in Hawai‘i. It’s important to note that we’ve already been making steady strides in this area. In fact, our three utilities reduced our greenhouse gas emissions by more than 22 percent between EPA’s 2005 baseline year and 2013.”
