Assessing capacity to deploy direct air capture technology at the country level – an expert and information entropy comparative analysis

Environmental Research Communications, 2023
An ever-dwindling carbon budget, resulting in temperature rise of 1.5 °C above pre-industrial levels projected between 2030–2035, has generated a necessity to explore climate mitigation technologies such as direct air capture (DAC).
