RENO —At an event marking the Raiders’ search for a possible Northern Nevada training camp site, Democratic gubernatorial hopeful Steve Sisolak took a few questions on his environmental stances and his voting record, which is the subject of a new negative TV ad from Republicans.

Here are some of the takeaways:

Plastic bag bans

Asked if he supported a ban on plastic bags, Sisolak said no.

“I understand that may have got some attention, but I'm not supportive of a ban on plastic bags,” he said.

A handful of Democratic lawmakers introduced a bill in the 2017 legislative session that would have required stores charge 10 cents for a single-use plastic bag over a four-year period, and then totally phase out the bags by 2022. After generating some buzz, the idea died without ever getting a hearing in the Democratic-controlled Legislature.

A bag ban is in place in California amid concerns that a proliferation of non-biodegradable plastic is threatening the environment as it disintegrates into smaller pieces and is consumed by animals.

Sisolak’s Republican opponent, Attorney General Adam Laxalt, has publicly taken aim at another movement to reduce plastic waste — straw bans. Laxalt included straw bans as part of a riff against California laws during a campaign speech in Reno in May, according to The Associated Press.

Renewable energy ballot question

Sisolak said he supports Question 6, a measure on the Nevada ballot this November that will require utility companies to draw at least 50 percent of their energy from renewable sources by 2030. A similar bill passed the Democratic Legislature but was vetoed by Gov. Brian Sandoval in 2017.

“I'd like to go further than 50 by 30,” Sisolak said. “I know Hawaii wants to go to 100. I don't know how realistic that is — don't want to set an unrealistic expectation but I think 50 by 30 is a beginning, not an end."

Raising taxes

The Republican Governors Association released a TV ad this week suggesting Sisolak would raise Nevadans’ taxes if elected based on a record of raising fees and a hotel tax during his tenure on the Clark County Commission.

His campaign said the ad was misleading. Asked why they described it that way, Sisolak said “I don't know what specifically they're saying.”

“I haven't seen the ad quite frankly, and my team might've commented on it -- I can ask [spokeswoman] Christina [Amestoy] what they said,” Sisolak said. “I try not to watch a lot of their ads. They've been extremely misleading up to this point.”

But he went on to defend his votes as a commissioner and his decisions during a decade on the Nevada Board of Regents, which oversees public colleges and universities.

“I've got 10 years' worth of history on the Clark County Commission and 10 years of history on the Board of Regents, and I'll stand by the votes that I've made,” he said. “I think we have low tuition in the state of Nevada compared to other states around the country. I monitor every fee or every increase before we had it, and if the RGA wants to say that we don't need more police officers on the street or that we don't need better roads, I mean, let 'em come right and say it. Let Adam Laxalt take a stand. I voted for more  public safety, I voted for better schools, I voted for increased road maintenance and building more roads and I'm proud of those votes.”

Laxalt has said he would sign a no-new-taxes pledge, and has said he supports repealing the Commerce Tax — a levy on businesses that make more than $4 million in Nevada revenue each year. Repealing the tax, however, would be a political longshot because Democrats are expected to control both chambers of the Legislature next year.
