| Abstract | Timely R & D investment in green technologies lowers mitigation costs with positive employment effects. Carbon revenues are sufficient to finance the additional R & D investment and generate economic benefits. Climate stabilization requires the deployment of several low-carbon options, some of which are still not available at large scale or are too costly. Governments will have to make important decisions on how to incentivize Research and Development (R & D). Yet, current assessments of climate neutrality typically do not include research-driven innovation. Here, we link two integrated assessment models to study R & D investment pathways consistent with climate stabilization and suggest a consistent financing scheme. We focus on five low-carbon technologies and on energy efficiency measures. We find that timely R & D investment in these technologies lowers mitigation costs and induces positive employment effects. Achieving 2 & DEG;C (1.5 & DEG;C) requires a global 18% (64%) increase in cumulative low-carbon R & D investment relative to the reference scenario by mid-century. We show that carbon revenues are sufficient to both finance the additional R & D investment requirements and generate economic benefits by reducing distortionary taxation, such as payroll taxes, thus enhancing job creation. |
