OTTAWA, June 20 (Reuters) - A Canadian oil industry

group has removed all content from its website, social media

pages, and other public messaging about environmental goals,

citing "significant uncertainty" over the federal government's

proposed anti-greenwashing rules.

On its website on Wednesday, the Pathways Alliance, a group

of six major oil sands firms, had said "Canada's oil sands are

on a path to reach net-zero emissions from operations,"

according to an archived copy.

By Thursday, the content on its website had been

replaced with a post about its concerns with Bill C-59, which

will implement the Liberal government's mid-year budget update

announced in November.

The bill was amended earlier this year to add

anti-greenwashing rules and has already cleared the lower House

of Commons and awaits passage by the unelected upper chamber of

the parliament.

"Imminent amendments to the Competition Act will create

significant uncertainty for Canadian companies that want to

communicate publicly about the work they are doing to improve

their environmental performance," the Pathways Alliance's

website now reads.

The alliance, which includes oil sands producers Suncor

Energy ( SU ), Imperial Oil ( IMO ), and Cenovus, did

not immediately respond to a request for further comment.

Climate advocacy group Environmental Defence said Pathways

Alliance's decision to take down content shows "they don't have

evidence to support the story they're selling."

Pathways, in its note, said specific guidance from Canada's

Competition Bureau may help direct its communications approach

in the future, and added that the group "remains committed to

the work we are doing."
