Greta Thunberg pass in your nation to protest Climate change

[The united American-Isreali empire]

I doubt she would like it. I put the economy first and the population in general is armed very well. With at the bareimium all serve in emergency defence forces.

[New Tussia]

New Tussia has a good approach to Climate Change in general. But, Greta would not be very welcomed due to the fact that she is vegan and meat-eating is large in the Tussian culture.
New Tussia is already very good with its environmental beauty, weather conditions, eco-friendlism, and many other facts.
She would not be very welcomed because Tussia views her as a brainwashed kid used as a political tool. Plus, we are already far on the path to prevent climate change. Cars aren't even used all that much except for far-travel, the police, and the military.

[Cartoonia]

Greta Thunberg would be seem as another crazy leftist, whom are frowned upon in Cartoonia. Climate Change is a concern, but not the top priority of the current administration. if she were to talk at Cartoon House, she would be met with rolling eyes and murmuring.if anything, she’d be persuaded by the Eco-Revolutionary party and the Jonestown Liberal party. If she does try to pull a wise one on industry, she will be held in a holding area until she is decided by both the Cartoon government and the government of Sweden.

[Nuroblav]

Greta Thunberg would probably receive a fairly standard welcome, like every other foreigner. Thunberg has some support from some Estantinese - many view her as an activist with good goals but wrong solutions to the problem.

[The Reasonable]

As our government is committed to combating climate change, she will find a receptive audience in the Meritocratic State of the Reasonable. She will be invited to a brief meeting with the National Governor and the National Board of Regents, who will ask for her perspective on how to solve the issue. Whether the government adopts all of her proposals will be another matter, but we will do our best to balance environmentalism with economic growth.

[The New Dog Nation]

We would immediately question how a human was able to actually enter our universe, as, despite our best efforts, we have not been able to replicate the disaster that teleported us here in the first place. She wouldn't have much to complain about here when it relates to climate change, as strict environmental standards have been followed here since before our nation was even founded mostly out of a fear that environmental impacts may have, in part, lead to the teleportation disaster in the first place.

[Deacarsia]

So how would your nation react to Greta's improvised visit ? How your citizen react to this government, how your government react ? and etc. How green is nation?

She would be run out of town on a rail. The citizens universally disapprove of her, as does the government. There are no environmental laws in Deacarsia beyond the enforcement of property rights.

[Pilipinas and Malaya]

If she happened to land in the country, she’d be invited for a speech in front of both houses to advance the government’s current de-carbonising and climate change combat platform. She will probably inspire political movements across many urban areas to accelerate current plans, which will probably not be possible because much of our states rely on such sources though constant advocation is made and being heeded to combat it.

[Champagne Socialist Sharifistan]

She would receive a peerage and be offered a meal at the Royal Palace.

[Nulvelith]

Our citizens are likely to snicker from behind closed doors. To her face, they will point out of the city, at the vast frozen expanse of glaciers and ice storms, and ask her where all this green she speaks of is. Then they'll take her downstairs, to the geothermal reactors and the nuclear power plants, and point at those. The entire rest of her visit will consist entirely of people blankly staring at her and wondering what sort of parents spoil a child so much that they let her go raise a ruckus across most of the world; and what sort of world they live in that would require such a child to fill the role.

[Bykhia]

Most of the citizens would offer their support and the President would probably stage a photo op or two but turnouts to her actual appearance would be fairly low. Also, I would be unsure how Greta Thunberg would be able to enter Bykhia in the first place...
