This one-day workshop took place on 19th May 2025 and brought together researchers working on the design, evaluation, and impact of climate policies aimed at fostering the development and diffusion of low-carbon technologies.
The shift toward a low-carbon economy calls for a combination of technological innovation, large-scale deployment, and well-designed public policies to guide and accelerate this transformation. In a context where technologies differ widely in their maturity and diffusion, climate policy plays a critical role in enabling systemic change.
This one-day conference gathered researchers working at the intersection of environmental economics, innovation policy, and energy transition. The program was structured into four thematic sessions that explored key aspects of the low-carbon transition.
The first session examined the diffusion of key mitigation technologies in hard-to-abate sectors.
Knut Einar Rosendhal (NMBU) presented an analysis of the complex interactions between emerging Direct Air Capture technologies and electricity market dynamics.
Jean-Pierre Ponssard (CNRS) considered the role of strategic interactions on the timing of adoption of Carbon Capture and Storage technologies in concentrated industries such as cement and steel.
The second session focused on the deployment of low-emission hydrogen.
Rind Alhage (PSE) examined how cross-sectoral dynamics between industrial material uses and energy applications can influence rollout pathways.
Albin Kasser’s (PSAE) presentation focused on climate policy design and the balance between technology neutrality and targeted instruments, for an efficient support of competing hydrogen technologies.
The third session explored the drivers of environmental innovation.
Stéphane Lemarié (GAEL) analyzed how different regulatory instruments, such as emissions standards, taxes, or quotas, influence the direction of innovation of biofuels between improved yield and cost reduction.
Eugénie Dugoua (LSE) empirically examined how public R&D funding influences the supply of new scientists in clean energy technologies.
The final session focused on industrial strategies for the green transition.
Juan Pablo Montero (PUC) considered the optimal design of Low Emission Zones, treating hybrids as transition technologies, stressing the importance of policy commitment.
Finally, Antoine Dechezlepretre (OECD) discussed how a coordinated mix of carbon pricing, innovation support, and infrastructure investment can accelerate the deployment of low-carbon technologies.
Together, these discussions highlighted the importance of aligning technological, economic, and institutional dimensions to meet the challenges of climate change mitigation.
