Legislators open doors to CO2 Technology

The Environmental Protection Agency is successfully working to remove barriers for CO2 (R744) in the US, while the European Commission reconfirmed once again the phase out of HFC-134a in cars as from 2011 on, it emerged from the SAE Refrigerant Symposium.

Speaking at the SAE Alternate Refrigerant Systems Symposium in Phoenix, USA, public authorities from the US, California, and the EU have reconfirmed their political will to reduce HFC-134a emissions from car air conditioning. They also raise the bar for any proposed alternative refrigerant, thus opening the door to sustainable solutions, such as R744.

US: Removing CO2 barriers on the federal and state level

The US Environmental Protection Agency (EPA) has reported great success in removing obstacles for the final approval of CO2 under the SNAP (Significant New Alternatives Policy) programme. SNAP proposes environmentally safe refrigerants in car air conditioning. After CO2 was listed as an acceptable alternative earlier this year, the EPA has now reconfirmed to recommend its use in the SNAP final rule, to be published by the end of this summer.

The EPA now estimates that the remaining state bans will be lifted by the end of 2007, making the use of CO2 in all states possible.

Joachim Wiesmüller, speaking on behalf of Europe's carmakers at the SAE event, urged the EPA to speed up the whole process and allow for an early use of CO2 in the US without restrictions.

EU stays firm on 2011 deadline for HFC-134a phase out

The European Commission has strongly reconfirmed 2011 as the starting date for a phase out of HFC-134a in all new cars sold in the EU. Agnieszka Kozakiewicz, representing the Commission, has thus underlined that there is no intention to amend the date as requested by the car industry.

California: Emissions reduction tools put pressure on HFC-134a

In California, transport accounts for 41% of all greenhouse gas (GHG) emissions. The state has therefore put forward progressive legislation to put pressure on the car industry to reduce GHG emissions. While the state is still waiting for a waiver from the EPA to enforce strict emission rules for cars, the California Air Resources Board (CARB) is moving to restrict the use of HFC-134a in car air conditioning. The latest proposal seeks to ban the sale of canned HFC-134a and any non-professional servicing of systems containing the high global warming refrigerant. CARB will now hold a public consultation to define more early action measures against greenhouse gas emissions by 2009.
