The concept of net-zero carbon emissions has emerged from physical climate science.
However, it is operationalized through social, political and economic systems. We identify …

This review explains the science behind the drive for global net zero emissions and why this
is needed to halt the ongoing rise in global temperatures. We document how the concept of …

The remaining carbon budget (RCB), the net amount of CO 2 humans can still emit without
exceeding a chosen global warming limit, is often used to evaluate political action against …

ES 6: 3-5 Replace “It is unequivocal that emissions of the well-mixed greenhouse gases
(GHG) carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2 O) from human activities …

The Paris Agreement's goal of limiting the increase in global temperature to 1.5° or 2° C
above preindustrial levels requires rapid reductions in greenhouse gas emissions. Although …

Research reported during the past decade has shown that global warming is roughly
proportional to the total amount of carbon dioxide released into the atmosphere. This makes …

In the five years since the Paris Agreement, achieving net zero emissions has become a
defining frame for climate action. We review over 4000 countries, companies, and …

While cumulative carbon dioxide (CO2) emissions dominate anthropogenic warming over
centuries, temperatures over the coming decades are also strongly affected by short-lived …

Abstract The Paris Agreement has opened debate on whether limiting warming to 1.5° C is
compatible with current emission pledges and warming of about 0.9° C from the mid …

Carbon dioxide removal (CDR) is essential to deliver the climate objectives of the Paris
Agreement. Whilst several CDR pathways have been identified, they vary significantly in …
