Sustainability of the IZT 2014

In 2014, staff and management of the institute discussed and adopted a sustainability strategy. It stipulates how sustainability is interpreted and implemented in the IZT. Staff specifically identified four fields of action:

·         Sustainable Research

·         Economic Sustainability of the IZT

·         Good Working Conditions at the IZT

·         Environmental Management at IZT

Since 2013, the IZT presents ecological and social sustainability performance data of the Institute in the annual report in addition to the economic data. 


Final Energy Consumption

Final energy consumption of the IZT 2011-2014

The final energy consumption of the IZT consists to more than 80 percent of gas for heating purposes and to less than 20 percent of electricity consumption. In 2014 final energy consumption was significantly lower than the previous year (see figure). This was mainly due to the lower consumption of gas for heating purposes, which is at least partly due to the mild winter. Electricity consumption also fell compared to previous years. One reason for this is the gradual abolition of energy-intensive equipment at the end of its useful life (eg IT equipment, refrigeration).

Business trips

Business Trips of the IZT 2011-2014

The total number of kilometers traveled in 2014 was well below the level of previous years. Overall, there has been a downward trend since 2011. This is mainly due to a further decline in air travel in 2014. Compared to 2013, they fell by two-thirds. No long-distance flights have occurred at all. On the other hand, the kilometers traveled by train rose in 2014 by about 20 per cent (compared to the previous year).IZT staff travel more frequently by rail than before and use airplanes less frequently. This change of behavior is the result of a decline in the number of international projects in which the IZT participates. Furthermore, the sustainability reporting has an interesting effect at IZT: the first-time assessment and publication of the CO2 impacts of IZT, to which air travel significantly contributes, supported an increase in balancing the advantages and disadvantages of air travel and a renewed glance through the "sustainability glasses".

CO2 Emissions

CO2- Emissions of the IZT 2011-2013

CO2 emissions in 2014 were well below the previous year's level. The main reason for this is the reduction of emissions from air travel. Air travel in 2013 still accounted for well over half of the institute’s CO2 emissions , their share in 2014 is only about one quarter of total emissions. The CO2 contribution of the entire business travel sector also fell, from more than 60 percent to 50 percent of total emissions. The IZT's business trips and gas consumption (for heating purposes) are now equal in terms of their contributions to CO2 emissions (each 50%).

Social Affairs

Equal opportunities for women and men

Regarding social sustainability, the IZT 2014 reports on the Institute's contribution to equal opportunities for women and men in the workplace by means of two indicators. The share of women in the workforce indicates that the IZT still offers more jobs to men than women in 2014, but the share of female employees has increased to 45 percent since 2012. With regard to the proportion of women in management positions, it is essential that in 2014, for the first time since the institute was founded in 1981, women formally took up leadership positions . It must be noted that an additional management level was introduced below the executive board in 2014 as a result of restructuring the institute. The six heads of research, female and male senior researchers, are responsible for the scientific management of one of the three research clusters. Until 2013, the management of the institute consisted exclusively of the executive board.
