Alberta's environment minister says Swedish climate activist Greta Thunberg "doesn't understand" the province, and signalled the government won't be laying out the welcome mat for the 16-year-old's upcoming visit.

Speaking to reporters outside the Alberta Legislature on Tuesday, Environment Minister Jason Nixon said Thunberg hasn't reached out to the UCP government, and the government has no plans to contact her.

"I do hope that if she does come to our beautiful province, she takes the time to talk to our state-of-the-art industry partners, who are working tirelessly to continue to produce the most ethical and environmentally friendly oil and gas products in the world," Nixon said.

"When you look at some of Ms. Thunberg's comments, she doesn't understand our province," Nixon said later, adding Thunberg needs to realize that Alberta must be an active partner in any global climate-change strategy.

On Saturday, Thunberg announced on Twitter she will travel to Alberta after a series of appearances in the United States.

Heading north again. Now follows a few days of well needed rest while enjoying the spectacular nature of Wyoming, Idaho and Montana.

Edmonton Mayor Don Iveson used the same medium Tuesday morning to extend a welcome to the climate activist.

"I'd love to invite you to [Edmonton's] city hall to discuss the Edmonton Declaration and some of the environmentally friendly projects we're working on," Iveson tweeted to her.

"Regardless of where you visit, I wish you nothing but the best."

NDP Leader Rachel Notley said that while she doesn't agree with every idea Thunberg proposes, she agrees "we need to move forward with concrete strategies to reduce our emissions."

She also said the UCP government must "stop distracting from the fact that people across the world are concerned about climate change."

"We need to be leaders; we don't need to be cowards."
