A previous version of a decision table is here:

Policy	Sector	Target	Action	Description
Renewable energy	Waterworks	0.5	Increase in use of renewable energy sources	50% of the energy requirements for hot water must come from renewable sources in case of new buildings or renovations of heating systems.
Renewable energy	Waterworks	0	BAU	The use of renewable energy sources doesn't change.
Energy efficiency	Building		New buildings are made energy efficient	Insulations of new buildings follow the requirements of whole Switzerland and new buildings must have a sunblind and thermal insulation for summer season.
Energy efficiency	Building		BAU	The energy efficiency of new buildings is not improved.
Incentive levy		0.05	5% levy on electricity bills.	5% Levy on each electricity bill for support (royalty) of modernising insulation of buildings (energy efficiency), renewable energy and pilot & demonstration buildings.
Incentive levy		0	BAU	There is no extra money for developing energy production and need.
Steering tax	Taxation		BAU	Mid 1990s the steering tax was introduced to the same amount as energy-prices reduction to avoid people wasting electricity.
Solar power advancement	Energy production		The increase of solar power in energy poduction.	Requires the regional energy supplier to accept an additional 2000 kWp of solar electricity annually at cost-covering prices and to feed this into its grid.
Solar power advancement	Energy production		BAU	No more solar power is used in energy production.

The strategy of Basel’s climate policy for GHG-reduction is predominantly an energy policy:

1.Use energy efficiently.

2.Advocate renewable energy.

3.Save energy. Sufficiency.

5 pillars of Basel-City’s energy policy

1. Conventional law

Buildings:
- Most stringent requirements in whole Switzerland regarding the insulation of new building (wall, roof, windows).
- 50% of the energy requirements for hot water must come from renewable sources in case of new buildings or renovations of heating systems
- New buildings must have a sunblind and thermal insulation for summer season
Industry:
- Large-scale electricity consumer in industry can be ask to do a safe-energy-analyse and do some ameliorations.
- etc.

2. An incentive levy

5% Levy on each electricity bill for support (royalty) of:
- Modernising insulation of buildings (energy efficiency)
- Renewable energy
- Pilot & Demonstration Buildings

3. A steering tax on electricity

Mid 1990s the steering tax was introduced to the same amount as energy-prices reduction to avoid people wasting electricity
The revenue is paid back; household-bonus & company-bonus

4.Advancement in solar power

Requires the regional energy supplier to accept an additional 2000 kWp of solar electricity annually at cost-covering prices and to feed this into its grid.

5. 2000-Watt-Society and Partnerships

A Project by the Canton of Basel-City and Novatlantis
Main focus of the 2000-watt-society:
- buildings
- mobility
  - “Near Zero Emission Vehicle"
  - “Clean Engine Vehicle“
  - Hydrogen-Driven Municipal Vehicle (hy.muve); a oxygen road sweeping vehicle
  - 100 ecological biogas taxis
  - e-mobility
    - Testing e-mobility
    - event packet for companies
    - carefree packet for companies and administration
    - e-sharing for private persons
    - Development strategy for e-bikes
    - Energy-tours www.energy-tours.bs.ch
- urban development
- carbon neutral administration
  - Effect as a prototype (paradigm)
  - Minergy P-Standard (shell and technical facilities) for new construction-buildings
  - Minergy Standard (shell) for renovation-buildings

Air pollution control with influence on GHG-reduction

Most important political instrument:

Clean air regulation of Switzerland
Clean air plan of Basel-City and Country

Clean air plan of Basel-city and country

Expamples with influence on GHG-reduction in target traffic:

Ecological motor vehicle tax
Tightening commercial control over parking space
Mobility management and agglomeration program (urban planning)
Public intensive infrastructures are obligated to decrease their traffic intensity
Regulations and limitations in prestressed air polluted city quarters

Infrastructure enhancing climate policy of Basel

Waste incinerator
- Integrated into the district heating. Function as a thermic power plant: 200,000 tons of waste supply our city with the power the equivalent of about 50,000 tons of oil.
- Equipped with the most effective smoke exhaust filter systems
Wood-fire power station
- Integrated into the district heating. Function as a thermic power plant.
- Substitutes about 11‘000 tons of oil
Aquifere of the community Riehen*
- A geothermal power station with deepgroundwater of 66 °C connected together with the block heat and power plant into the community heating of Riehen.
Deep heat mining project
- This project had to be stopped unfortunately because the drillings have caused an earthquake on 2006.
Electricity by the IWB
- Electricity in Basel is 100% renewable.
- 99 % is hydraulic energy.
- The rest is solar energy or wind power.
- Basel is not allowed to consume nuclear power because due to law

Most important shifts of climate change which are expected in Switzerland till 2050

In winter, fall and springtime temperature will increase around 2°C in summer around 3°C
Decrease of Rainfall in summer of 20% and increase of 10% in winter
Generally more heatwaves, dry periods, strong rainfalls and floods

The Canton Basel-Stadt is most affected by:

Heat wave hot-spot-effects in the City (“heat-island”)
Rising ground-water temperatures, which decreases the possibility to use ground-water only for cooling-process.
Rising temperatures of the river Rhein during heat-waves, which results that industry is not possible to cool their production-process with Rhein water (fish kill).

Key words

The climate change, Politics, Basel, Urgenche
