New data shows that Oregon is meeting its goal to halt the growth of carbon emissions.
The Department of Environmental Quality says carbon emissions in Oregon declined by 8 percent between 2005 and 2010.
Researchers tell The Statesman Journal newspaper that the changes are due in part to a higher use of fuel-efficient cars and other clean technology.
Oregonians may also have cut back on their energy use due to the recession.
The report also compared emissions per capita between Oregon, Washington and California.
Although all three states are below the national average, Oregon's rates are the highest among the three.
The Oregon Legislature passed a law in 2007 setting new goals for the state's carbon emissions.
The state hopes to reduce emissions to 10 percent below 1990 levels by the year 2020 and to 75 percent below those levels by 2050.
