Carbon sequestration is not a successful strategy

Due to:

loss of efficiency

• 8-14% points

storage problems

• leakages

• long term observation necessary

public protest

• no acceptance for pipelines and on shore storage reservoirs

Conclusion

For a secure and economic energy supply are necessary:

• long term calculable energy prices

• free allocation of certificates for 14 years for new entries

• fuel specific CO2 benchmark

• increase of the cap for JI/CDM projects in case of high percentage of auctioning

• energy mix consisting of

• gas

• coal

• nuclear

• renewables
