Event Information

About the Forum

This event portal provides comprehensive information and resources for participants of the 6th Forum on Long-term Energy Scenarios.

Government energy planners face evolving challenges in the global energy landscape, including integrating emerging technologies, managing geopolitical risks, and aligning planning with climate commitments and sustainable development goals.

Long-term energy scenarios (LTES) are critical tools for addressing these complexities, strengthening institutional processes, and guiding policymaking for resilient clean energy transitions.

IRENA's Global Network of Long-term Energy Scenarios (Global LTES Network) and Clean Energy Ministerial Initiative on LTES for the Clean Energy Transition provides a unique forum for government scenario practitioners to exchange insights, share experiences, and collaborate on advancing the clean energy transition.

Target Audience

Energy planners, government officials, energy industry representatives, intergovernmental agencies, and the scientific/climate community.
