Transcripción del resumen original del autor: This report from Study Group IGM2 is focusing on the role of natural gas compared to other energies and the meaning and influence of climate change policies on marketing activities. IGM as well as a number of IGU delegations were contacted by questionnaires and in a second step were interviewed by an international research institute. The final report refers to the following subjects: – perspectives of energy policies such as national climate protection policies and energy taxes, – emissions trading and joint implementation, – natural gas and appliance technologies such as condensing appliances and combined heat and power and – marketing activities. The report illustrates that natural gas in most of the countries that participated in the study today is the second most important energy. And the share is expected to increase, e.g. in power generation. On the other hand we see a national climate protection programme in ¾ of the countries calling upon industry and private households to save greenhouse gases and to use energy more efficiently. This development should further promote natural gas in the future due to its advantages compared to other energies. Environmental aspects are of significant importance to the marketing work. This results e.g. in campaigns illustrating the energy efficiency of the wide range of gas appliances or the business field of natural gas vehicles that save pollutants and CO2. The report also explores common and coordinated marketing activities in general and approaches of the gas industry to cooperate with market partners.
