The first thing that jumped out at me was the 12 million tonne (12 MtCO2) rise in emissions since last year's report.

Last week, the Canadian government released its annual greenhouse gas report, which now includes data for 2017.

In response to questions about the latest jump in emissions, Environment and Climate Change Minister Catherine McKenna sent a statement to National Observer saying: “Canada’s climate plan is working, and the overall trend in emissions is downward toward 2030.”

So, the oil & gas industry added another huge emissions burden -- and caused another lost year in the national climate fight — because that industry refuses to stop increasing its pollution.

Unsurprisingly, it was caused by a surge in the pollution from the oil & gas industry. Their Canadian emissions jumped 12 MtCO2 from last year’s report. Yep, that equals the entire national increase.

In practical terms, this means that policy makers need to figure out how to eliminate another 12 MtCO2 to meet Canada's climate targets. And now the country has one less year to pull it off. (Technically, the challenge actually got 13 MtCO2 harder because of a revision to the 2005 baseline starting point. See the end notes for geeky details). To give you a sense of scale, increasing Canada's climate challenge by 13 MtCO2 is equivalent to tossing another New Brunswick's worth of emissions onto the already huge pile that needs to be eliminated.

One thousand years might sound shocking but, actually, I've been low-balling the problem. If you look more closely at the emissions data, we would never reach Canada's climate targets.

And it will take nearly a thousand years to reach Canada's 2050 target level. So, grab your calendar and pencil in a "We Did It!" celebration party for the year 2961 AD.

Sure, that is technically a "downward" trend. But, as my chart on the right shows, it is so foot-draggingly slow that it will take two centuries for Canada to reach its Paris target at that pace.

We now have twelve years of data — covering 2005 to 2017. At this half-way point, emissions have only declined by two per cent.

As most people know, countries pledged a 2030 climate target as part of the global Paris Agreement. The Trudeau government pledged to meet a goal already set by Stephen Harper for a 30 per cent reduction from 2005.

Okay, let's take a look at the "overall trend in emissions" towards Canada's 2030 target.

For example, since 2005 the industry's climate pollution in Canada has been rising an average of two per cent per year.

Because the oil & gas industry has its own "overall trend" when it comes to emitting climate pollution. And its emissions trend has been rapidly and relentlessly upwards for as long as Canada has been keeping records.

I've added oil & gas industry emissions to my chart as an orange line.

As you can see, the oil & gas industry already pollutes fifty million tonnes more than the entire country’s 2050 climate target.

Oil & gas industry vs provinces

To further illustrate the overwhelming impact of this industry's surging pollution in Canada, I created the chart below using the newest data. It compares oil & gas industry emissions (orange line) to those from entire provinces (blue).

Back in 2005, Ontario emitted almost fifty million tonnes more than the oil & gas industry did.

Since then, Ontario cut emissions 22 per cent (mostly by closing its coal plants). Rapidly cutting emissions is exactly what the science says everyone must do to avoid a full-blown climate crisis.

In contrast, the oil & gas industry jacked up their climate pollution in Canada by 23 per cent.

That huge surge in emissions drove this one industry's pollution past the provincial totals from Quebec, British Columbia, Manitoba, Nova Scotia, PEI and Newfoundland & Labrador — combined.

It's an understatement to say that the oil & gas industry's climate pollution is out of control in Canada.

Canada's climate promises vs actions

I'll finish up with a quick walk down memory lane looking at Canada's long history of climate promises, and the emissions trends that emerged after each of them.

Our first stop is more than 30 years ago. It was 1988. Ronald Reagan was the U.S. President; the Soviet Union was still a thing; and Calgary hosted the Winter Olympics. That year, Prime Minister Mulroney set Canada's first climate target. The target required an average cut of one per cent per year.

So, how much climate pollution did Canada end up cutting?

As my next chart shows, Canada's emissions have risen by 116 million tonnes.

Then, twenty years ago, the Chretien government promised that Canada would cut climate pollution under the 1997 Kyoto Accord. Once again, that target required an average cut of one per cent per year. And once again, Canada increased its emissions instead.

Ten years ago, the Harper government promised that Canada would cut climate pollution by — yep, an average of one per cent per year, under the 2009 Copenhagen Accord. That same year the government also made a longer-term pledge — an average of two per cent per year through 2050. Canadian emissions kept growing.

And here's a friendly reminder that the country’s Copenhagen pledge comes due next year. If you’re wondering how close Canada is to meeting it, the new greenhouse gas report says we are polluting 110 million tonnes more than promised.

Finally, in 2016, the Trudeau government promised an average cut of two per cent per year under the Paris Agreement. As we saw at the top of the article, emissions have gone up.

Foot-dragging means steeper and steeper cuts

Clearly, Canada has a long history of promising to clean up its pollution while doing the exact opposite. The consequences are starting to bite.

One of these consequences is an increasingly energized and dangerous climate system — droughts and refugees, people dying in heat waves or dying in their cars trying to escape hellish wildfires, collapsing forests, rising ocean acidification, destabilized fisheries, bigger floods, stronger storms, rising seas, an extinction crisis….

Another consequence that gets too-little attention is that we've squandered the chance to cut emissions back gradually. Notice in the chart above how the pace of the promised cuts has doubled. Because the government didn’t implement policies to cut back at one per cent per year during the decades when we had the chance, Canadians are now facing cuts of two per cent per year to meet our targets.

The unrelenting laws of mathematics mean that foot-dragging will make the challenge steeper and steeper over time. For example, if Canadian emissions are still at 2017 levels in 2020, Canadians will need to cut three per cent per year just to hit the meagre “Harper targets” we codified in the Paris agreement. That's triple the pace needed to meet the Kyoto and Copenhagen targets when they were first pledged.

Past trends vs future projections

This article has looked at past emissions trends. And for good reason. Past polluting behaviour has been a perfect predictor of whether Canada would honour each new climate promise. So far, I haven't seen action from the oil & gas industry or strong-enough climate policies to make me think this round will be any different.

However, some folks might also want to look at the future projections published by the federal government. These are based on economic computer models that try to include the impact of all current and proposed climate policies. Hey, I'm one of those people, too. If that sounds interesting to you, I've got another article that surveys the most recent years of future projections.

Spoiler alert — it's titled "Canada's climate gap widens again."

GEEKY END NOTES

Here are some details on revisions from the latest emissions report that were discussed above.

• The 2005 baseline year was revised from 732 MtCO2 to 730 MtCO2. Canada's climate targets are based on a percentage reduction from 2005 levels. A result of lowering this baseline number is that the final targets numbers will fall a bit as well. In this case, Canada's 2030 Paris target dropped about 1 MtCO2, to 511 MtCO2.

• The 2016 national emissions were revised up by 4 MtCO2 -- from 704 MtCO2 to 708 MtCO2.

• The 2016 Oil & Gas industry emissions were also revised up by 4 MtCO2 -- from 183 MtCO2 to 187 MtCO2.

Canada’s climate pledges

Here are the details on Canada's climate pledges.

In 1988 emissions were ~600 MtCO2. That year the Mulroney government set Canada's first climate target. It targeted a 20% cut by 2005. A 20% cut in 17 years is roughly 1% per year.

In 1997 emissions were 687 MtCO2. That year the Chretien government set a target under the Kyoto Accord for 6% cut below 1990 by 2012. That worked out to an 18% cut below current levels at the time, over the next 15 years. This is roughly 1% per year average.

In 2009 emissions were 682 MtCO2. That year, the Harper government set a target under the Copenhagen Accord for a 17% cut below 2005 by 2020. That worked out to a 11% cut below current levels at the time, over the next 11 years. That is 1% per year average. That same year, the Harper government also committed to a 2050 target that was 80% below 2005 levels. That worked out to a 79% cut over current levels at the time, over the next 41 years. This is roughly 2% per year on average.

In 2016 emissions were 708 MtCO2. That year the Trudeau government set a target under the Paris Agreement for a 30% cut below 2005 by 2030. That worked out to a 28% cut below current levels at the time, over the next 14 years. That is roughly 2% per year on average.

In 2017 emissions were 716 MtCO2.

If emissions in 2020 are still at that level, then meeting the Paris target will require cutting emissions 28% in ten years. That’s 3% per year average. Another three years of foot-dragging after that would require cutting 4% per year on average to reach the target.
