The state Assembly passed the bill last week.
Cuomo tossed a last-minute curveball, asking the state's Solicitor General Barbara Underwood to review the measure for possible safety concerns - threatening to veto it if he did not like her assessment, the Post noted.
Democratic Gov. Andrew Cuomo called it the nation's best plan to address climate change.

Many Republicans in NY opposed the measure, which was passed after Republican President Donald Trump moved to crack down on illegal immigration on several fronts.
Proof of legal status is required for Real IDs, and the Department of Homeland Security has ruled that it would allow states to issue non-compliant driver's licenses to applicants for whom "lawful presence is not determined". "If this bill is enacted and challenged in court, we will vigorously defend it". "This is the right step forward for NY state as we continue to advocate for comprehensive immigration reform on the federal level".
"This is not about driver's licenses, this is about law and order and the United States" right to defend the sanctity and sovereignty of our borders, ' said Sen. Opponents, however, say the measure will encourage illegal immigration and undermine the law.
New York Republican Chairman Nick Langworthy in a statement said the bill was one of several measures demonstrating the state's Democrats "are in lockstep with leftist radicals and could care less about the priorities of taxpaying New Yorkers".

USA Today reported that advocates say the new law will allow those workers to obtain "insurance and avoid the threat of deportation if they are pulled over". "The key to this bill is not the political intent but the legal effect". Eliot Spitzer's 2007 push for "illegal licenses", and a Siena College poll recently found that 53 percent of New Yorkers oppose it, with just 41 percent in favor.
Democrats supporting the measure argue that illegal aliens learn to drive, and get tested and insured as a result, adding to overall road safety for all.
