For several years, progressive requirements for the reduction of global CO 2 output have already led to efforts in Europe, North America, Japan, China, Australia and other regions. The European automotive industry defined emission goals, which were eventually supplanted by binding legal requirements.
All economic regions share an intermediate milestone in 2015, targeting emission maxima between 125 and 180 g/km CO 2 . The most ambitious targets have been enforced by the EU, where a reduction in fleet emission to 95 g CO 2 per km is defined as upper limit until 2020 . Not far away are the U.S. standards of 54.5 mpg in 2025. Since the mandatory introduction of DRL functions for new vehicle types from 2011, lighting technology has also been introduced in the discussions.
