Global greenhouse-gas emissions are still rising: when will they peak?

"Global fossil-fuel emissions are likely to hit yet another record high this year, scientists announced today at the COP30 UN climate summit in Belém, Brazil, but there are signs that the world is approaching a peak. Indeed, some researchers argue that carbon dioxide emissions might have already begun to decline, and many think that overall greenhouse-gas emissions (including methane, nitrous oxide and fluorinated gases) could begin to decline by the end of the decade."

"Emissions among the major industrialized countries, which are responsible for the bulk of historical emissions, have been falling for more than two decades (see Which regions emit the most greenhouse gases?). However, they are rising nearly everywhere else. Although much of the focus tends to fall on rapidly developing juggernauts such as India and China, the growth is widespread a"

Global fossil-fuel emissions are projected to reach a record level this year, with CO2 from fossil fuels and cement rising 1.1% to about 38.1 billion tonnes. Factoring in a projected drop in deforestation and other land-use changes could yield a slight decline in overall carbon emissions, but substantial uncertainty remains. Projections do not place a global emissions inflection point until around 2030, although emissions appear to be flattening in some areas. Total greenhouse-gas emissions are roughly 10% higher than a decade ago and remain far above levels consistent with limiting warming to 1.5°C. Emissions have fallen in major industrialized countries but are increasing across most other regions, including rapid growth in countries such as India and China.
