Passenger cars and the 1.5°C climate target: the role of propulsion technologies, CO2 limits and real-world energy demand
To stay within the 1.5°C climate target, the global CO2 emissions after 2018 should not exceed 383 Gt. Proportionally distributed, this relates to about 109 Mt for the Swiss passenger cars, which implies the need to reduce current emission levels rapidly to zero. Reducing demand has the advantage of fast implementation, but is limited in reduction potential. As long as individual motorized transportation exists, the only way to reach zero emissions is through technological change. But which technologies hold the largest decarbonization potentials? The talk presents results from the SCCER Mobility Strategic Guidance project, which show the role of powertrain electrification. After having identified the desired technologies, the challenge is to introduce them into the national fleet to stay within the CO2 budget. A tool for policy maker to promote alternative technologies are emission limits for new passenger cars. The question is: Are the current limits stringent enough? Furthermore, these limits address type approval values, which are known to differ from on-road operation for conventional cars, but also for alternative technologies. Results from a conducted field study with alternatively propelled cars will be shown and an approach how to estimate this emission gap, which is relevant for the CO2 budget.
