SEATTLE -

A new city report finds that Seattle's core greenhouse gas emissions dropped by 6 percent between 2008 and 2014 even as the city's population grew by 13 percent.

The report released Wednesday says nearly 3.5 million metric tons of carbon emissions were released in 2014 from transportation, building energy and waste management -- areas where local government policies have the most influence.

Emissions from transportation made up two-thirds of that total. Between 2008 and 2014, emissions from driving declined by 2 percent as residents traveled fewer miles and used more fuel-efficient vehicles. Emissions from energy use in buildings also dropped 13 percent in that time.

City official Jessica Finn Coven says the numbers show Seattle can grow its economy while also reducing climate pollution. But she says more must be done to meet the 2030 goal to cut emissions by 58 percent from 2008 levels.
