Rename to carbon budget?

I think this is the more common name. Two of the criteria on Wikipedia:article titles is to have a recognizable and natural name, and I think carbon budget is superior in both regards. Using a Google search indicates that carbon budget has 816,000 hits, while emissions budget has 47,500. In terms of English, the current title is a tat bit awkward, in the sense that the first word is a plural and plurals don't work well as an adjective. Femke Nijsse (talk) 15:40, 30 April 2019 (UTC)[reply]

Maybe. (a) I agree carbon budget is more common, (b) there are other types of emissions unrelated to global warming, and (c) many greenhouse gases are carbon-based (CO2, CH4, HFC, PFC; biggest exception is N2O). However the term Global carbon budget now redirects to Carbon cycle, so it would be best to ask people on that page what they think. Maybe carbon budget and global carbon budget need to go to a disambiguation page and keep emissions budget here? Otherwise emissions budget and carbon cycle need headnotes pointing to each other. Numbersinstitute (talk) 23:13, 30 April 2019 (UTC)[reply]

I've asked on that page. I think a disambiguation page isn't necessary, as I've not seen carbon budget used to describe the concept of global carbon budget. The terms seem quite well seperated on Google at least. A headnote might be an idea though. Femke Nijsse (talk) 17:04, 2 May 2019 (UTC)[reply]

I agree carbon budget has become the much more common name. Are we ready to rename? SaffyLane (talk) 12:40, 17 July 2021 (UTC)[reply]

Done by "TheAafi" as there was a redirect with history - hatnote added Chidgk1 (talk) 17:26, 17 August 2021 (UTC)[reply]

Removed text block about CDR

I've removed this text block about CDR as I felt this didn't fit here (as it could blow out this article big time if we now explain everything to do with reducing GHG emissions etc.). Instead, I've added an excerpt for climate change mitigation which is the key concept to ensure one stays within one's carbon budget, right?:

Carbon dioxide removal

In order to keep global emissions within a carbon budget, global CO₂ emissions need to decline to net zero. The Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6) highlights that the deployment of carbon dioxide removal (CDR) measures is unavoidable if net zero CO₂ emissions are to be achieved.^[1] These CDR measures are required to counterbalance hard-to-abate residual emissions.^[1] The IPCC assessment further highlights that "the scale and timing of deployment will depend on the trajectories of gross emission reductions in different sectors".^[1]

CDR can fulfil "thee different complementary roles" according to the IPCC, always in addition to "deep, rapid, and sustained emission reductions":^[1] First, CDR can lower net CO₂ or net greenhouse gas emissions in the near-term; second, it can counterbalance residual emissions from sectors for which currently no other reduction measures have been identified or for which these are considered too expensive or difficult to implement (e.g., emissions from agriculture, aviation, shipping, industrial processes) in order to help reach net zero CO₂ or net zero greenhouse emissions in the mid-term; and third, CDR can be used to achieve net negative CO₂ or greenhouse gas emissions in the long-term, if deployed at levels exceeding annual residual emissions.^[1] EMsmile (talk) 08:12, 10 May 2023 (UTC)[reply]

New first sentence of the lead

I've changed the first sentence of the lead to be broader: A carbon budget is a concept used in climate policy to help set emissions reduction targets in a fair and effective way. I used Chat-GPT to help me come up with this. What do people think of this new first sentence? EMsmile (talk) 08:14, 10 May 2023 (UTC)[reply]

Update the Scenarios Chart

Wondered if somebody wants to update the chart to the numbers of 2023, now that they are released. Onyru (talk) 00:05, 8 January 2024 (UTC)[reply]
