CO2 reduction scenario

To reduce CAU's carbon footprint to zero, various reduction strategies and scenarios are being developed for the fields of energy, mobility und operational processes. Unavoidable CO2 emissions must be ecologically compensated from a certain point in time.


Reduction of energy-related CO2 emissions

1. Reducing energy consumption
The initial internal target of reducing energy consumption by 10% by 2020 compared to 2013 has been achieved. Energy-related CO2 emissions have thus been reduced by around 5,000 tonnes per year.
2. Procurement of green electricity
In 2018, CAU started using green electricity from renewable energy sources for the main campus, and since 2020, also for the Technical Faculty. By purchasing green electricity, around 13,000 tonnes of greenhouse gas emissions were avoided since 2018. Since 2020, CO2 emissions could be reduced by an additional 3,000 tonnes.
3. Procurement of thermal energy

The CO2 emissions associated with district heating have been halved to around 3,500 tonnes per year with the commencement of operations at the new Kiel coastal power plant at the beginning of 2020. Consequently, the currently remaining energy-related CO2 emissions amount to around 4,000 tonnes.

Figure: The development of energy-related CO2 emissions (in tonnes) since 1995 and the savings achieved by 2020 (The value for 2020 is projected).
It is to be expected that by 2020, the CAU will succeed in reducing energy-related CO2 emissions by 85% compared to 1995. This means that the political CO2 reduction target has been exceeded by far, despite increasing student numbers.


Reduction of mobility-related CO2 emissions

In the 2014 mobility concept, the CO2 emissions of the daily commuter and business travel  for all CAU members were calculated to be 6,500 tonnes per year. 60% of these CO2 emissions were attributed to single car journeys. In order to reduce these quantities, two key points were defined:

1. Implementation of the mobility concept

The measures to promote cycling and the expansion of mobility services, as laid down in the mobility concept, should help to reduce car use by 16%. This could save 1,200 tonnes of CO2 emissions per year.


2. Connecting CAU to an efficient public transport system

The long-term goal is to connect the CAU to an efficient local public transport system which is already on the agenda of the Kiel city management with the so-called light rail system (external link to the state capital of Kiel, German page). This will further reduce the number of solo car journeys.


Reduction of operational CO2 emissions

So far, no information can be provided about the CO2 emissions caused by university operations.
