The international conference on natural refrigerants to bring together policy makers, the finance community, and industry experts to discuss the huge potential of CO2, ammonia, and hydrocarbons as HFC-free cooling and heating solutions. A milestone on the way to Post-Kyoto Protocol talks in Copenhagen. Supported by an EU-funded project.Some highlights: * A Policy Vision: Policy makers from different countries and non-governmental organisations will present their view on how to overcome barriers to natural refrigerants at the national and international level. * A Workshop for each Refrigerant: For each of the three refrigerants CO2, ammonia and hydrocarbons, dedicated workshop sessions will present case studies of real-life experience with heating and cooling applications, as well as market trends. * A Word from Investors: Atmosphere 2009 will invite key players from the investment community to outline financial opportunities for a wider use of natural refrigerants. * A Call for Action: Before the official start of Atmosphere 2009, "Recommendations for Copenhagen" to consider natural refrigerants on global environmental policy agendas will be presented during a Sunday reception. The document will speak with one voice on behalf of all proponents of CO2, ammonia and hydrocarbons. It will be handed over to decision makers in Copenhagen. * A Manual for CO2: Seven partners from the academia and the industry have joined forces under the EU-funded project NARECO2 to develop the most comprehensive manual on the operation and safe handling of CO2 systems available in the EU to date. The book will be handed out to all Atmosphere 2009 participants.
