Candidate for governor Maura Healey on Sunday denied she’s abandoning some of her boldness to avoid making a campaign misstep and promised to help create a “whole climate corridor” in Massachusetts to help the world move away from fossil fuels and toward renewable energy.

During an interview on WCVB’s “On The Record” program Healey, a Democrat who is winding down her second term as attorney general, also declined to say if she supported removing a 1986 voter law that is leading to nearly $3 billion in tax refunds this fall.

On the topic of energy and climate change, Massachusetts has a law designed to achieve net-zero greenhouse gas emissions by 2050 and co-host Ed Harding asked if that was soon enough or if Massachusetts should do better.

Healey didn’t say whether 2050 was soon enough and said the state “has been really aggressive” and “we need to continue to be aggressive in this space.”

She said a lot of technology enabling the transition from fossil fuels to renewable energy is being developed in Massachusetts, creating an opportunity to create a “whole climate corridor” here.

“We ought to take advantage of that,” she said. “We ought to use that to harness manufacturing to create great, great jobs and there are so many jobs that are available in this space. It’s the now, it’s the future and Massachusetts should take advantage of it. And as governor, I promise I will be really competitive on this.”

On taxes, Healey reaffirmed her support for a constitutional amendment authorizing a 4 percent surtax on annual household income above $1 million, a change that could generate $1.3 billion a year in new revenue.

“This is a really targeted measure that’s going to affect less than one percent of the population here in Massachusetts,” she said.

Income surtax opponents warn that while it is intended to generate new revenue exclusively for education and transportation, the Legislature could also reduce spending in those areas that is tied to existing revenues.

When co-host Janet Wu pressed Healey to commit to spending surtax revenue on transportation and education “in addition” to other revenues for those purposes, Healey said, “I don’t really understand the debate there Janet. I mean, my office and I had to look at this. And it’s pretty clear under the law that, should the voters act and pass Question 1, that that money would go towards infrastructure, transportation and education.”

“In addition to what’s being spent right now?” Wu responded.

“In addition,” Healey said. “That’s right.”

Some Democrats have sharply criticized the 1986 law (Chapter 62F) that’s leading to the historic tax refunds, which will flow in the largest numbers to some of the state’s highest earners.

Wu asked Healey if that voter law should be removed or stay in place. “I’m not sure about that,” Healey said. “I mean, ultimately, it’d be up to the Legislature to decide.”

Asked if popular Republican Gov. Charlie Baker would be “the model” for the type of governor Healey would be, the attorney general said she had “high regard and respect for the way that Governor Baker has led.”

“Obviously, the next governor will have to put her own mark on government and the administration,” she said. “But I’ll tell you, I’m going to continue with what’s working and look to fix what isn’t.”

Wu capped the interview by asking Healey, who leads Republican opponent Geoff Diehl in the polls, whether she has abandoned her boldness as attorney general in order to avoid missteps that could lose her votes.

“No,” said Healey, a former pro basketball player. “I was an athlete and as any athlete, the last thing you do is play it safe.” She later added, “Yeah, you just gotta play. You always play like you’re 17 points behind and the surest way to lose any sport and any game is to play it safe. You just have to be who you are.”
