PORT ANGELES — Olympic Climate Action and Carbon Washington are sponsoring two Port Angeles events in support of Initiative 732 for a Revenue-Neutral Carbon Tax, featuring the initiative’s principal author, Yoram Bauman.

Carbon Washington is a grass-roots campaign seeking to put Initiative 732 on the 2016 ballot.

I-732 would institute a revenue-neutral carbon tax in Washington state, using revenue from a tax on fossil fuels to reduce existing taxes.

Carbon Washington is working primarily through volunteers to collect 315,000 signatures by December.

Bauman, Carbon Washington founder and executive committee member and I-732’s principal author, will speak at the Elwha Klallam Heritage Center, 401 E. First St. in Port Angeles, tonight (Sunday).

He will speak from 6:30 p.m. to 8:30 p.m. on “Climate Change — It’s No Joke: An Evening of Fun, Fossil-Fuel Fungibility and Fundraising with Yoram Bauman.”

There is no charge, though the event is intended as a political fundraiser.

On Monday, he will speak to the Port Angeles Regional Chamber of Commerce during its luncheon meeting at noon in the Red Lion Hotel banquet room, 221 N. Lincoln St.

“Why a Carbon Tax Would Be Good for Our Local Community — Let Us Count the Ways” is the title of his speech.

Chamber lunch rules apply; attendees must buy lunch for $15 or drinks only for $3.
