Alan Guebert: Honesty, courage first steps in ag climate fight

Last May, the Canadian farm group National Farmers Union submitted a detailed response to the Canadian government’s earlier “Draft Greenhouse Gas Offset Credit System Regulations.”

The response, like the government request, went relatively unnoticed in U.S. ag circles.

It shouldn’t have because the 23-page reply by the 200,000-member National Farmers Union was as shocking in its brevity as it was bold its central tenet: “For the next two decades,” the union strongly urged, the nation should “shelve offset credit systems and emissions trading … and instead focus on actually reducing fossil fuel combustion and emissions.”

The reason, the report explained, was a second hard poke in Ottawa’s eye: “According to … expert analyses, offset systems should not be first-line measures. Instead, offsets should only be deployed after we achieve deep reductions in actual greenhouse gas emissions…”

In short, the National Farmers Union is saying, “everyone knows the key to reducing carbon in our atmosphere tomorrow is to stop putting carbon in our atmosphere today. So why are we talking about offsets and credits first?”

The bluntness of a national farm group saying what almost every soil and climate scientist knows to be true is refreshingly honest.

Any immediate, measurable impact farmers and ranchers anywhere might have on climate change will not be tied to building manure digesters on 5,000-cow dairies or nudging no-till corn acres a few percent in the coming decade.

Instead, every farm and ranch needs to be “reducing fossil fuel combustion and emissions” today.

The National Farmers Union doubled down on its reduce-now, sequester-later position in late March when it published a first-of-its-kind “comprehensive assessment of agricultural greenhouse gas emissions in Canada.” The report strongly supported reduction again.

The “assessment,” done by Darrin Qualman, a long-time National Farmers Union researcher and self-described “civilizational critic,” shows that carbon emissions by Canadian agriculture grew from 67 million metric tons in 1990 to 84 million metric tons in 2019. That rise, however, masks two untracked sources – one good, one bad – of carbon dioxide in Canadian agriculture.

First, “Emissions from nitrogen fertilizer production and use have nearly doubled since 1990” and, if current trends continue, will “nearly double again by 2050.”

In 2019, carbon dioxide emissions “related to nitrogen fertilizer…” were 22 million metric tons, or more than one-quarter, of Canadian ag’s total CO2 emissions.

Very few folks saw that coming.

Second, neither quantified how a massive shift in Canadian agriculture, the two-prong move away from nearly all tillage for both cropping and summer fallow, improved carbon sequestration. In short, the near-total adoption of no-till by Canadian farmers since 1990 sequestered an estimated 13 million metric tons of carbon dioxide in 2019.

That’s remarkable.

It’s also not enough, said Qualman in a telephone interview, “because Canada’s ag emissions continue to climb. Right now, our farmers and ranchers offset only about 7% of what all agriculture – from cattle to fertilizer dealers – emit, or less than 1% of the greenhouse gas emissions for all of Canada.”

To some, that might sound like a lot of blue sky for improvement, eh?

“Not really,” said Qualman, “because the basic math doesn’t work. If you’re sequestering 6 million tons (of carbon dioxide) a year and emitting 84 million tons, you’d be a net buyer of carbon credits, not a net seller, right?”

Right – if you’ve done the honest math of the actual problem.

In fact, if climate change requires all net CO2 emitters to cut output, farmers from Canada to Columbia to China would be net buyers of carbon credits, not net sellers.

That's just a fact, said the only ag energy analyst I know to have ever done the math for a country’s agriculture.

Despite the fact that “we’re running with scissors,” Qualman is optimistic that the world can avoid total climate disaster.

“If we repurposed our industrial capacity for, say, three or four years of World-War-II-style commitment, we could rapidly change our climate trajectory. Rapidly.”

The question isn’t if we can do it; the question, he offers, is if we have the courage to try.
