In both the United States and Canada, activism against tar sands, pipelines and climate change has soared in recent years.
But while President Obama has encouraged citizens to "stand up and speak up" to demand change on energy, Canadian Prime Minister Stephen Harper's administration has tried to silence critics of pro-tar sands policies.
In the most recent evidence, seven influential environmental organizations have become the subject of rigorous audits by the Canada Revenue Agency.
Activists allege that the scrutiny is an attempt by the Harper administration to subdue tar sands opponents as decision time looms for pipelines needed to bring Alberta's landlocked oil to market—the Texas-bound Keystone XL and the Northern Gateway to the Pacific Coast of British Columbia.
"Canadians are starting to understand that the government has overstepped and overreached in its attacks against environmentalists and scientists," said Tzeporah Berman, a Vancouver-based environmentalist and co-founder of the activist group ForestEthics. "We're seeing a growing grassroots movement as a result. … People are angry."
The prime minister's office directed requests for comment to the Canadian Revenue Agency (CRA). Noël Carisse, a spokesman for CRA, said that since 2012 "the CRA has conducted additional review activities focused on political activities. Audits are being conducted in addition to our regular audit activities, and will include charities from across the entire spectrum of charitable activity."
The revenue agency is auditing the environmentalists for possible abuse of their nonprofit charitable status, which exempts them from paying taxes and allows donors to claim contributions as tax deductions. Canadian law states that nonprofits can only use 10 percent of their resources for political advocacy work. The CRA is investigating whether the groups exceeded this limit.
For decades, Canadian nonprofits interpreted political advocacy to mean they couldn't endorse candidates or elected officials. Like in the United States for tax-exempt organizations, support for or criticism of government policy was customary.
"They are seemingly reinterpreting what they perceive as being political activity," said Tim Gray, executive director of Environmental Defence, one of the green groups being audited. "It is a shifting landscape."
If the CRA determines that the organizations passed their annual political advocacy limit, they could lose their charitable tax status, forcing them to pay taxes and potentially driving away donors. That could cause some of the groups to shutter their doors, Gray and Berman said.
In addition to Environmental Defence, other groups being investigated include the David Suzuki Foundation, Tides Canada, West Coast Environmental Law, the Pembina Foundation, Equiterre and the Ecology Action Centre, according to the CBC, which first reported the audits.
The targeted groups have been instrumental in raising public awareness about the impacts of tar sands development on the environment and climate. They stoked a grassroots movement that helped delay the Northern Gateway pipeline in Canada and, together with U.S. environmentalists, helped make the Keystone XL a climate red line for Obama.
Environmental organizations appear to be bearing the brunt of the recent investigations.
While most of the groups are still under review by the agency and are therefore staying mum, Gray said his organization received its results from the CRA.
"They told us that basically everything we do is no longer charitable," he said. The group immediately filed an appeal. If rejected, Gray said he is unsure what that will mean for his organization's future.
Across the Border
The audits are the latest in a string of attacks on environmentalists and scientists in recent years by a Harper government that has made oil sands expansion a centerpiece of its economic agenda. Since Harper took office in 2006, production of Alberta's carbon-intensive tar sands crude has doubled, and Canada has set a goal to at least double it again in the years ahead.
Simultaneously, the conservative administration has cut funding for climate science research, shuttered environmental research labs and buried government reports highlighting the dangerous climate and environmental implications of runaway oil sands development. It has also muzzled its own scientists from speaking about the issue, cancelled thousands of environmental assessments for pipelines, oil sands mining and other development projects, and gutted 70 environmental protection laws in 2013 alone.
In 2012, the government listed environmentalists as a terrorist threat.
Amid the erosion of environmental law in Canada, across the border in the United States the Obama administration has sought to apply federal law to combating climate change. The centerpiece of this work is an historic regulation under the Clean Air Act to cut carbon pollution from the nation's coal plants.
