Abstract for: The Power of Self-reinforcing Feedback: With a little help from your EV friends in Norway
With EV sales rate exceeding 50%, Norwegian EV policy is seen as successful. Yet, with a CO2 tax level 10 times that of the EU trading system's, it is considered unaffordable by many. The policy experiment uses a global energy model where local EV uptake influences battery costs globally. Through lower battery costs, the CO2 impact of the policy influences EV - and photovoltaic electricity's uptake and thus CO2 emissions globally. Taking the power of this positive feedback loop into account, the global CO2 emissions reduction are 4.4 times higher than those in Norway and the CO2 cost only twice current EU levels.
