A lot of the information in this article is old, bad, outdated, and wrong, and generally in ways that makes things seem worse than they actually are. In some cases with some bizarre omissions.

For example, it's peculiar that there's an entire section singling out and talking about 2007 and talking about how much emissions rose that year...but strangely doesn't mention that it's the year that US emissions peaked. It's peculiar that reference 4 used to justify that is a dead link...that from looking at the URL, I'm not sure it was ever valid. It appears to be a generic 'search result not found' page. It's peculiar that there's an image showing CO2 levels from the Mauna Loa observatory, even though that observatory is about 2500 miles from the continental United States. It's peculiar that the top few paragraphs are very, very selectively quoting individual years and talking about 2005 predictions for 2012...when here we are in 2018. That's really old data, and a lot of it hasn't played out as predicted. Why does the opening paragraph compare current emissions to 1990? You pretty much have to go back that far to find a year when emissions were lower. It looks like it's being selectively chosen to try to present US emissions as rising, when they're not, and actually the US has been one of the leading counties in the entire world in terms of emissions reductions for roughly the past 10 years.

"In 2017, US had largest decline in CO2 emissions in the world for 9th time this century"

https://www.eia.gov/environment/emissions/carbon/

"Emissions have declined in 7 out of the past 10 years, and energy‐related CO2 emissions in 2017 were 849 MMmt (14%) below 2005 levels"

https://www.c2es.org/content/u-s-emissions/

"Emissions increased by 5.1 percent between 1990 and 2015 but are down 12.4 percent from the 2007 peak."

It starts at 1990 because that is the international start year for all countries - see UNFCCC or Paris Agreement Chidgk1 (talk) 15:34, 30 June 2021 (UTC)Reply[reply]

I see the EPA has pie charts for the standard IPCC sectors and for economic sectors. I want to do a pie chart for economic sectors for another country where I know the figures for IPCC sector. Any idea how I can convert from IPCC sector to economic sector? I could not figure it out from the EPA website. How does the EPA calculate the figures for economic sectors do you know? Or should I ask them directly? Chidgk1 (talk) 07:01, 4 September 2021 (UTC)Reply[reply]

JetGreen40 - you seem to know a lot about the USA - do you know whether this "economic sector" measurement is some USA specific thing or if not how can I calculate it for another country where I have the IPCC figures? There is info at https://ourworldindata.org/emissions-by-sector but that only goes up to 2016 and I have not yet found out how they calculated it. For example how do the EPA work out that "commercial" is 6.9% of the total? Chidgk1 (talk) 11:06, 9 December 2021 (UTC)Reply[reply]

I'm not entirely sure whether it is a USA-specific thing, but this EPA report on the GHG emissions inventory provides some useful information. Specifically, see Box 2-1 on page 2-32 for their methodology. JetGreen40 (talk) 22:46, 9 December 2021 (UTC)Reply[reply]

Thanks - by the way you can remove the "update" tag when you think a section is up to date. Chidgk1 (talk) 14:48, 11 December 2021 (UTC)Reply[reply]

I've added new sources and information in the "Mitigation" section. I'm happy to go ahead and remove the update tag unless anyone else would like to add further updates. JetGreen40 (talk) 22:12, 3 January 2022 (UTC)Reply[reply]

Chidgk1 - Do you think this section is current enough to remove the tag? Thanks, JetGreen40 (talk) 00:07, 11 January 2022 (UTC)Reply[reply]

No objections - you know best. Someone can always add a new tag if the BBB is passed Chidgk1 (talk) 07:34, 12 January 2022 (UTC)Reply[reply]

So as the social cost of carbon does not cover damages to other countries https://www.theguardian.com/us-news/2022/feb/12/trump-judge-biden-climate-metric-greenhouse-gases presumably other countries would be within WTO rules to impose a carbon tariff on US exports? Chidgk1 (talk) 12:26, 13 February 2022 (UTC)Reply[reply]

Maybe one of you Americans could add details of how it is calculated? Chidgk1 (talk) 12:41, 13 February 2022 (UTC)Reply[reply]

I am proposing to move all the mitigation content to climate change in the United States to make it more consistent with the structure we are using for the other climate change in country X articles. Also the climate change in the United States does have a section about mitigation already, so now we have mitigation content spread over two articles. See also here for the proposed standard structure of the articles in the group "climate change in country X". Pinging User:Chidgk1. I've also just proposed the same at the China GHGE article. EMsmile (talk) 18:43, 28 November 2022 (UTC)Reply[reply]

Another reason for my proposal is that mitigation is about more than just GHGE reductions. It's also about enhancing carbon sinks. Hence, it fits better in the climate change articles rather than in the GHGE emission articles. EMsmile (talk) 18:43, 28 November 2022 (UTC)Reply[reply]
