The environment is a hot topic on the campaign trail.

Critics of Governor Rick Scott plan to spend millions attacking his stance on climate change.

A group of environmentalists went to the Florida Capitol Monday demanding that Scott come up with a federally-mandated plan to cut Florida's greenhouse gas emissions by 38 percent within 15 years.

So far, the governor hasn't done it, which is why the petitions are being dropped off now, two weeks before Election Day.

The not-so-subtle message: protecting the environment takes leadership, and Bay area environmentalist Susan Glickman said Florida's not getting it from Scott.

“I think when they find elected officials that are siding with the big polluters, the big monopoly utilities and giving them rate increases while they're raising people's electric bills, I think that gets people pretty mad, and that's what we've seen here,” said Glickman.

In a tight race, every issue can count, including the environment.

Both Republicans and Democrats agree there are votes to be hand, but they're taking different approaches to winning them.

In his fight to hold onto the governor's mansion, Scott is pledging one billion dollars in new green investments. Just what those investments would be and where the money would come from, Scott hasn't said.

But he does say his record on the environment is strong.

“Our Division of Emergency Management has spent about $130-million, I think, the last three years in dealing with flooding around our coast, if you look at the money we've put into the Everglades, the money we're putting into Indian River Lagoon, we're trying to do everything we can to protect our environment,” he said.

Still, critics say if that were true, Scott would be cracking down on utility companies.

Instead, whether it's over the air or now, in his own office, the governor's facing election season outrage over climate change.

The man behind those TV attack ads is a billionaire environmentalist from California. He plans to spend $10 million on ads against Scott.
