The source gives the following explanation to the scenarios' levels:
If all countries followed the rated country鈥檚 approach, warming could be held below鈥攂ut not well below鈥2掳C for the 鈥淎lmost sufficient鈥 category. For the 鈥淚nsufficient鈥 category, the range is 2掳C to 3掳C, for the 鈥淗ighly Insufficient鈥 3掳C to 4掳C, and for 鈥淐ritically insufficient鈥 above 4掳C. Given that the overall rating is an aggregate of different elements, we do not provide a warming range for it.

GHG emissions projections in the UK 2022-2035, by scenario
Under the current policies and actions, and in an optimistic scenario, GHG emissions in the UK were forecast to fall to *** MtCO鈧俥 by 2035. This decrease is considered to be insufficient if the target of limiting global warming to *** degrees Celsius is to be achieved. In a scenario compatible with the *** degrees Celsius target, UK emissions would need to reach *** MtCO鈧俥 by 2035.
