IIASA Energy, Climate, and Environment Program Director Keywan Riahi will talk about historical energy transformations and various energy and emission scenarios for the students of the Austrian Academy of Science (ÖAW).

In 2019, 84.3% of the world's energy demand was dependent on fossil sources such as coal, oil, and natural gas, and only 15.7% came from sources with low fossil CO2 emissions. Of this, 3.3% was wind and solar energy, and these two inexhaustible energy sources are expected to replace nearly all fossil fuels in the coming decades. Successful implementation of this almost insoluble task is a prerequisite for limiting global warming to a maximum of 1.5 °C and, in the more distant future, to the average temperature of the 20th century. However, profound technological changes in demand systems (mobility, housing, consumer goods and industry) are needed in order to meet these future energy and climate goals.

Together with Univ.-Prof. Dr. Georg Brasseur of the TU Graz, Riahi will hold a seminar on Energy transition and mobility about technological options, potentials, and costs of carbon removal, and will discuss the risks of the different measures with the aim to bring understanding for Europe's energy transition and future mobility among the participants.

For more information on the Seminar see the ÖAW page (in German).
