Emission budget and necessary emission reduction pathways to meet the two-degree target agreed in Paris Agreement without negative emissions, depending on the emission peak[1]

An emissions target or greenhouse gas emissions reduction target is the central policy instrument of international greenhouse gas emissions reduction politics and a key pillar of climate policy.[2][3][4][5][6][7]

An "emissions target" may be distinguished from an emissions budget, as an emissions target may be internationally or nationally set in accordance with objectives other than a specific global temperature. This includes targets created for their political palatability, rather than budgets scientifically determined to meet a specific temperature target.[8][9]
