Have you ever read a greenhouse gas inventory?

@evan then my answer is no, but I skimmed over some and read only the results.
@grob that seems pretty legit! You can get a lot of information from a top-line scan or an executive summary.

@tarix29 that's awesome! Thanks for doing it.
@tarix29 agricultural emissions are tricky, too!

@grob also, consumption-based inventories are uncommon.

@evan how does industry self-reporting fit into the inventory?

@Django you took a lot of leaps ahead of me. I'm not sure what you're asking.
If you're asking whether self-reporting matters for corporate GHG inventories, the answer is yes. They're almost entirely self-reported afaik. They are also investor relevant information, so it's a big deal if you fake your reporting.

For local, provincial, and national inventories, it depends. A typical inventory uses some sort of activity data and multiplies it by an emissions factor. So, total number of vehicle kilometers traveled, times a factor representing emissions per kilometer, gives total emissions for transportation.

@Django especially for industrial emissions, climate data specialists have to collect data from industry (how much steel manufactured, how many cattle raised). For energy use, it's usually numbers reported by the energy companies. So, yes, corporate reporting plays a big part.

@Django if you're asking about the story you're sharing: that's not actually about a greenhouse gas inventory.

@evan thanks for the context above, I realized my knowledge gaps seeing your poll after reading that story yesterday.

@evan no leaps intended, I’m trying to understand the difference between the Inventory and the Federal dataset mentioned in the story.
“The federal dataset is built using a mix of modelling and real-life measurements regularly collected by Environment and Climate Change Canada (ECCC) researchers from sites across the country. Those data include emissions from the entire oil and gas supply chain — from extraction to distribution to final use or export — to paint a really complete story,"

@evan IIUC the federal dataset would be part of what is included in the National Inventory

@Django ah, I might have misread the story! I thought it was about emissions reductions from adding a new pipeline.
-

@Django "The industry wants Ottawa to rely on Alberta’s measurement of methane emissions rather than the federal government’s own measurements when it calculates reductions in methane in its deal over a new pipeline and other support for the industry."
So, it's about generally tracking fugitive emissions. I stand corrected!

@themediumkahuna does the university integrate the results into a climate action plan? And actually execute on that plan? That's pretty awesome.

@log they aren't going to be great.

@evan I believe I read one for my first year seminar in college, which was about the end of the world.

@BathysphereHat that's really interesting!

@evan It was a really cool class! We talked about a lot of different scenarios, from those completely outside humanity's control (like a near Earth supernova) to those very much within it. Climate change was naturally a big focus.

@PhoenixSerenity I didn't know that! Wow.

@PhoenixSerenity I didn't know that! Wow.
@evan We measured up in Arctic Circle & compared with Southern, more populated zones.
