Intentionally removing carbon from the atmosphere with negative emission technologies (NETs) will be important to achieve net-zero emissions by mid-century and to limit global warming to 2 °C or even 1.5 °C (IPCC 2018). Model scenarios that consider NETs as part of mitigation pathways are...

Assessing climate policies that involve temporary overshoot of temperature targets requires an accurate representation of carbon cycle and climate dynamics. Here, we compare temperature overshoot climate policies obtained with the dynamic integrated climate–economy (DICE) integrated assessment...

Ocean alkalinity enhancement (OAE) deliberately modifies the chemistry of the surface ocean to enhance the uptake of atmospheric CO 2 . The chemical efficiency of OAE (the amount of CO 2 sequestered per unit of alkalinity added) depends, among other factors, on the background state of the...

This paper reviews quantitative estimates of the economic and environmental benefits from different forms of international co-ordination on carbon pricing based on economic modelling studies. Forms of international co-ordination include: harmonising carbon prices (e.g. through linking carbon...
