Making mobility efficient

Efficient mobility means alternative drive systems and fuels and the use of efficient means of transport (e.g. local public transport),the introduction of mobility management and innovative information technologies. dena campaigns

for a reduction in carbon footprints among all users of road transport. But everyone will have to contribute in order to achieve greater efficiency. dena uses campaign pages like to provide initial information.

Building a practicable transport transition

Our climate and environment are suffering under the growing demand for mobility. This is why dena promotes alternative fuels and technologies as well as innovative mobility concepts, advocating energy-efficient structures within the transport sector.

In recent years, worldwide mobility has grown at a dizzying pace, especially in road transport and aviation. This has produced significant impairments in the quality of life due to greater environmental pollution and a rise in greenhouse gas emissions. 18 percent of emissions in Germany are produced in the transport sector. Road transport accounts for 95 percent of them. The challenge: mobility needs to become more sustainable and efficient in order to protect the environment and the climate and to improve quality of life.

The challenge of efficient mobility

We need to be mobile. But to ensure that it is more sustainable for society and the climate, mobility will have to become more networked and energy-efficient. Efficient drive systems, green fuels and optimised mobility of passengers and freight across the whole range of transport solutions will have to provide important contributions in this respect. But Germany is facing a grave challenge. Personal and freight transports have risen by over 50 percent since 1990. Nevertheless, the Federal Government wants to achieve a 10-percent reduction in energy consumption within the transport sector by 2020, compared with 2005. Current figures show that there has been a two percent rise in consumption. The situation in regard to CO2emissions is similar: Although the 2014 Action Programme on Climate Protection pencilled in a 7 to 10-million-tonne reduction in transport emissions in Germany by 2020, the momentary statistics indicate a rise of six million tonnes.

Achieving more together

A consistent emission avoidance strategy is needed in the transport sector in order to tackle these major challenges. The national and European frameworks must be adjusted to incentivise low-emission transport systems and make innovative mobility concepts more attractive.
dena is engaging with industry, politics and society to develop sustainable transport solutions and to share positive experiences in a process of constant dialogue with other nations.
Here, dena sees itself as a driver to improve fuels and technologies  and to increasingly move the carriage of persons and goods to energy-efficient and low-emission means of transport and transport systems.

  • The key facts on energy efficiency in buildings, 200 pages
  • Analyses, forecasts and scenarios are presented in clear charts and explained in bullet points
  • Range of topics: from residential and non-residential buildings to  owner and tenant structures  in  the context of political, economic and historical events

Energy-Efficient Building in China

dena has been developing and implementing energy-efficient construction projects in China since 2006. Advanced technology and experience gathered in Germany are adapted and transferred to the conditions in the respective region, using experts on the ground. The aim is to improve the market conditions for energy efficiency technologies, impart knowledge and establish concepts suitable for mass marketing of energy efficiency in China.


  • Project start: 2006
  • Since 2010, dena has launched 30 pilot projects
  • First efficient house standard introduced in Hebei in 2015
  • Partners: Construction ministries of both countries, the Center of Science and Technology of Construction (CSTC), the  Chinese Society for Urban Studies (CSUS), and various provinces, specialist associations, and German and Chinese companies.
