State Attorney General Eric Schneiderman is trying to hide ­e-mails about his support of a climate-change policy that’s being targeted by President Trump, a conservative group charged in Manhattan court Tuesday.

The organization, E&E Legal, sued Schneiderman last year claiming he led a group of AGs in silencing climate-change skeptics.

The group says Schneiderman is refusing to disclose documents that show collaboration with pro-climate change activists.

The AG is entitled to keep intra-office communication private, but must hand over information sent to outside parties. At issue is an Oct 2015 e-mail that Schneiderman’s aide Christina Harvey sent to her boss and an outside political consultant, Kristie Stiles.

E&E’s lawyer, Francis Menton, says the AG’s office waived any right to keeping the documents private by sending them to the operative. The AG’s lawyers say Harvey just wanted Stiles to print the e-mail, and didn’t intend for her to read it.

The judge said she’ll rule on the matter in the coming weeks.
