Dietz, S.; Bowen, A.; Doda, B.; Gambhir, A.; Warren, R. (2018): The Economics of 1.5°C Climate Change. In: Annu. Rev. Environ. Resour. 43 (1). DOI: 10.1146/annurev-environ-102017-025817.
„Setting off with higher emissions will make 1.5°C unattainable quickly without recourse to expensive large-scale carbon dioxide removal (CDR), or solar radiation management (SRM), which can be cheap but poses ambiguous risks society seems unwilling to take. Carbon pricing could reduce mitigation costs substantially compared with ramping up the current patchwork of regulatory instruments. Nonetheless, a mix of policies is justified and technology-specific approaches may be required. It is particularly important to step up mitigation finance to developing countries, where emissions abatement is relatively cheap.“
