Cactus Event: Energy Sufficiency in Catching Up EconomiesCactus

1. April 2022 - Energy Sufficiency in Catching Up Economies

Energy sufficiency as the missing driver on the way to carbon neutrality in catching up economies

Web seminar : 01 April from 10:00 to 11:30am CET

While energy efficiency policies have become mainstream in OECD countries, energy consumption is still increasing, so that there is still a long way to go to reconcile with 1.5 degrees compatible pathways. In Central and Eastern Europe, energy consumption levels are catching-up rapidly, leading the way for emerging economies worldwide. Energy sufficiency is key to address this increase of energy consumption, and can act as a key complement to efficiency and renewables on the path to carbon neutrality, but also to a deeper environmental sustainability beyond just climate aspects.

In the framework of the CACTUS project and on the sides of the 2022 Berlin Energy Transition Dialogue, the négaWatt Association, Fraunhofer ISI, the REKK Foundation and the Lithuanian Energy Institute are inviting you to their web seminar.

In this session, experience from designing scenario pathways based on sufficiency, efficiency and renewables from Germany and France will be complemented by examples on the integration of sufficiency from the CACTUS project in Hungary and Lithuania and from scientific literature and global models aiming at 1.5°C target and submitted to the IPCC. Solutions will be presented and discussed to integrate sufficiency into climate and energy scenario models and strategies and of European countries and beyond.

The webinar will take place back to back with a presentation of the EnSu energy sufficiency policy database, providing for a comprehensive sufficiency BETD side-event session.
