Robert Redford is calling Alberta oil "the dirtiest oil on the planet."

Just days after singer Neil Young publicly denounced the Alberta oilsands, Redford appears in a video attack on the Keystone XL pipeline as part of a new climate change campaign.

The video is just one of several put out Monday by the National Resources Defense Council (NRDC) on DemandCleanPower.org, an activist website aimed at collecting petition signatures against the Keystone XL pipeline.

“Developing the Canadian tarsands is destroying our great northern forest at a terrifying rate. It is producing enough carbon pollution to wreak havoc with our climate for decades to come. And the pipelines that carry this toxic tarsands fuel are a direct threat to our own drinking water supplies,” Redford, a longtime anti-oilsands activist, says in the video.

He adds that Alberta oil is, "great for oil companies, but it is killing our planet.”

Redford is well known for his on-going crusade against Calgary-based TransCanada Corp.'s Keystone XL pipeline.

In 2011 he appeared in a three-minute video on the New York Times' website, speaking out against the pipeline that, if built, would travel through several U.S. states.

Redford has also written at length about the destruction he believes the pipeline would cause in a series of blog posts for The Huffington Post.

"We already know that tar sands development causes more carbon pollution than conventional oil. And now a slew of experts from industry insiders to financial analysts all agree that the Keystone XL is the linchpin for Big Oil's plan to more than triple tar sands production over the next 20 years -- and the climate disruption that will follow," he wrote in a post published today.

"...The Obama administration can help North America solve our climate problem is by rejecting the Keystone XL tar sands pipeline and calling on the Canadian government to cap tar sands production," he continues.

Celebrities Carole King, Juila Louis-Dreyfus and Robert F. Kennedy, Jr., also recorded videos for NRDC's campaign.

Prominent People Who Oppose Keystone XL Pipeline

"Tell President Obama to reject the climate-destroying, Keystone XL tar sands pipeline and lead the way to a clean energy future instead," reads the website's call to action.

President Barack Obama has not decided whether to grant approval to the pipeline. The decision is likely to come sometime next year.
