Range of measures and scenarios
The basis for all further deliberations is the desired scenario, aiming at a CO2 reduction of 30 % by 2005 (as compared to 2005) and the minimum scenario, with 2010 as target year and a first holding step in 2005.
The minimum scenario comprises a catalogue of measures, which goes beyond the currently foreseeable trend, but is still considered feasible under legal and political aspects, while the desired scenario contains further and stricter measures, which are to help to fulfil the target.
The established measures were assessed according to their
- CO2 reduction potential
- technical and legal feasibility.
Those environmental protection measures are taken, which have the highest CO2 reduction potentials using the available means. What must be permanently considered is the conflict between the protection of economic interests (especially the labour market, industry, social sustainability) and limited public funds on the one hand and the biggest possible environmental effect through appropriate measures on the other.
We must note here that not all environmentally friendly measures also serve to protect the climate. The example of the catalytic converter shows that its introduction has had no immediate effect on fuel consumption and CO2 emissions and therefore does not noticeably contribute to climate protection. The same is true for measures protecting sensitive areas (like residential areas), which might even lead to an increased vehicle mileage and can thus have counter-productive effects in terms of climate protection. Similar effects are expected in Stuttgart from certain energy conversion measures (combined heat and power systems, power generation).
The individual measures are listed, explained and summarized in special sheets. The lists contain in particular:
- A short description of the measure - What is to be done?
- The objective of the measure - What is to be achieved?
- The target groups whose energy consumption is to be reduced by the measure - Who is to be reached?
- The presentation of accompanying measures - What can additionally be done to support or intensify the effect of this measure?
- A list of the obstacles, which might delay or prevent the realization of this measure - Which obstacles must be overcome?
- The actors (can be identical with the target group) - Who is to get active or take the initiative to reach or motivate the target group?
- A presentation of the necessary steps - What is to be done?
- A rough assessment of the effort, priorities and period of implementation.
After the presentation of the measures, the resulting saving potentials for primary energy and CO2 are given for both the desired and the minimum scenario for the basic year 2010.
What is also listed is the amount of investments and supportive funds needed for the implementation of the measure as well as additional operating costs when indicated. These are taken as basic values for the assessment of the measure in terms of efficiency and cost-benefit-ratio.
