» Efficient use of energy harbors large savings potential: “The demand for electricity in Germany can be reduced by 12 percent by the year 2020. It is both technically and economically feasible and requires, in addition to concerted efforts to exploit renewable energies, drastic energy savings measures and increasing energy efficiency.
This would coincide with a considerable abatement of climate-damaging carbon dioxide (CO2) emissions of 80 percent in 2050 as compared to 1990. These are the findings of a study carried out by the Federal Environmental Agency on behalf of the Federal Ministry for the Environment.”
According to the Federal Environmental Agency, the impact on health and the environment of particulate matter and NOx emissions make it necessary to further reduce waste gas caps of diesel engine vehicles. The technology to do so is already available. The UBA has issued a recommendation on how to modify the caps for particulate matter and NOx in effect as of 2005, namely EURO 4 for passenger cars and EUROIV/V for commercial vehicles.
The UBA’s recommendation is: a EURO 5 particulate cap for passenger cars of .0025 g/km should correspond to an emissions reduction of 90 percent as compared to the EURO 4 cap. The NOx cap of .08 g/km for diesel passenger cars would correspond to the cap for Otto engine passenger cars in effect starting in 2005 with EURO 4.
