Mr. Kunert, what share of global oil consumption is made up of fuel consumption? Currently, over half of the world’s oil is used for transportation purposes, of which roughly four-fifths are used for road transport – which is the focus of our report. Roughly one-tenth (and increasing)... more

Dr. Belitz, how has investment in research and development, or R&D, in Germany developed in recent years? We analyzed investment in research and development over the past few decades and observed particularly strong growth after 2007. In fact, Germany has now almost met its target of investing... more

The transport sector - road transport, in particular - accounts for more than half of world oil consumption. In the future, the transport sector’s share of oil consumption will grow even more, primarily due to the increasing use of motor vehicles in developing and emerging countries. Road freight transport will also take on greater significance. And overall, gasoline - and, increasingly, diesel - will continue to dominate the fuel mix. A trend reversal in which road transport moves toward a more intensive use of alternative fuels such as liquefied petroleum gas (LPG) and natural gas, and alternative drive systems such as hybrid cars (HEVs) and battery electric vehicles (BEVs), still cannot be observed - despite government support. Given that gasoline and diesel will also be dominant in the future, additional efforts should be made to reduce CO2 emissions and improve the environmental friendliness of motor vehicle traffic. Given the deleterious environmental effects of diesel fuel, its preferential tax treatment should be abolished.

DIW Berlin has examined the effects of investment in research and development on economic growth in Germany and other OECD countries. Their results show that an increase of one percentage point in research and development spending in the economy as a whole leads to a short-term average increase in GDP growth of approximately 0.05 to 0.15 percentage points. The coefficient for Germany is at the upper end of that range. The analysis shows, however, that it is difficult to separate the effect of aggregate R&D into contributions from private- and public sector R&D. R&D investment in both sectors has seen strong growth in Germany in recent years, particularly when compared internationally. For a country that owes its prosperity largely to its research-intensive manufacturing sector and to production-related, knowledge-intensive services, research and development remains key to future growth. It is therefore essential that Germany does not ease up on its efforts to increase R&D investment.
