Does the phrase "put into effect" in the original sentence mean " in practice" or "practically"?
Gas percentage is likely to rise in coming years if carbon prices are put into effect.(Original sentence)
Gas percentage is likely to rise in coming years if carbon prices are inexpensive in practice.(right?)
Gas percentage is likely to rise in coming years if carbon prices are inexpensive practically.(right?)

In addition to this question, can I use "are gone into effect" or "are come into effect" instead of "are put into effect"?

Perhaps there must be error in my book....
Doesn't the phrase "put into effect" mean "in practice" or "practically" except for the sentences I mentioned?

"Put into effect" does not mean "practically" or "in practice." It means something has become active. Like "The smokers enjoyed their last indoor cigarette right before midnight, when the city's new smoking ban went into effect."

Thank you now I can understand the phrases.
Is it right to understand your sentence as below?

"The smokers enjoyed their last indoor cigarette right before midnight, and after the day the city's new smoking ban went into effect."

Oh, I have more question about this.
If I say the sentence

"The smokers enjoyed their last indoor cigarette right before midnight, when the city's new smoking ban went into effect.".
I maybe pause at the comma. But can I use the expression right above when I make a conversation with other people?
Or can this kind of sentence be used in the News on air?

At midnight the new law went into effect. At 11:59 PM it was legal to smoke inside. At 12 midnight, it was not. The law went into effect at midnight.

No. "When" does not translate to "and after the day."

[eggcracker]

No. "When" does not translate to "and after the day."

Thank you. Now I get at least how to understand the original sentence.
Incidentally, I've been schooled that I should translate the structure such as "~, when" , "~, who"
into the expressions like "~, and after that time", "~, and someone do something/~, and someone is something"
It's quite confusing. Would you give me some grammar rule if possible?

"The smokers enjoyed their last indoor cigarette right before midnight, when the city's new smoking ban went into effect."

In this case the "when" is to be understood like "...midnight, which was the time when the city's..."
