Major Milestones in the Development of Solstice yf refrigerant

 HFO1234yf History
Date Major Milestones
16 September 1987 The signatory states of the UN sign the " Montreal Protocol ". It aims to prevent emissions that harm the earth's ozone layer.
1 January 1989 The "Montreal Protocol " comes into effect.
11 December 1997 The signatory states of the UN adopt the " Kyoto Protocol ". The industrial nations commit themselves to reduce emissions of greenhouse gases until 2012 by 5.2 percent below 1990's level.
8 March 2000 The EU Commission's European Climate Change Program intensifies the efforts to implement the " Kyoto Protocol ". Working groups discuss options , auto vehicle air conditioning comes into focus.
10 October 2000 The EU Environment Council requests from the EU-Commission to consider measures to reduce emissions of F-Gases (fluorinated greenhouse gases) in auto vehicle air conditioning.
2003 The European Commission approves HFC-152a, R744 and other refrigerants as possible new refrigerants for motor vehicle air conditioning.
16 February 2006 Honeywell presents new, climate-friendly refrigerants.
17 May 2006 The EU directive on air conditioning systems in motor vehicles (2006/40/EG," MAC-directive ") imposes strict requirements on refrigerants applied. Only refrigerants with a Global Warming Potential (GWP) of less than 150 will be approved for use in mobile systems.
4 July 2006 The EU F-Gas Regulation (EU regulation no. 842/2006) and the MAC-directive of the European Parliament and Council on emissions of F-Gases in auto vehicle air conditioning and on amending directive 70/156/EWG come into effect.
14 February 2007 Honeywell and DuPont introduce new refrigerants with low GWP at the annual " Alternative Refrigerant Winter Meeting " of the German Association of the Automotive Industry (VDA).
13 February 2008 Honeywell and DuPont present the new and market-ready Solstice yf refrigerant at the annual VDA " Alternative Refrigerant Winter Meeting ".
1 December 2008 The registration process of Honeywell's new low global warming potential refrigerant for REACH begins. REACH, the new EU chemicals regulation, requires that chemical substances on their own and in preparations have to be registered to the European Chemicals Agency (ECHA).
8 December 2008 Honeywell's low-global-warming-potential refrigerant is endorsed by the renowned SAE's (International Society of Automobile Engineers) International Cooperative Research Program for use in vehicles: "... offering greatest potential to meet environmental and consumer needs".
1 January 2009 After intensive testing of R744, SAE's International Cooperative Research Program prioritizes Honeywell's new low global warming potential refrigerant over R744 as the refrigerant for practical use in vehicles.
28 May 2009 The German Association of the Automotive Industry (VDA) demands a global standard for refrigerants.
4 August 2009 Honeywell's new low global warming potential refrigerant is intensively tested by the Japanese Ministries of Health, Labour and Welfare, Economy, Trade and Industry and of the Environment and approved for practical use.
13 October 2009 The US Environmental Protection Agency (EPA) accepts Honeywell's new low global warming potential refrigerant in its SNAP-program for use as low GWP-refrigerant in auto vehicle air conditioning.
5 January 2010 The European Patent Office grants Honeywell the patent for the new low-GWP refrigerant for auto vehicle air conditioning.
20 May 2010 Honeywell and DuPont announce a joint venture to manufacture the new low GWP refrigerant.
23 July 2010 GM chooses to use Solstice yf refrigerant in cars of its U.S. brands Cadillac, Chevrolet, Buick and GMC from 2013 on.
28 February 2011 EPA approves Honeywell's new low global warming potential refrigerant for use in auto vehicle air conditioning. EPA's SNAP report criticizes the tests conducted by the German Bundesanstalt für Materialforschung und -prüfung BAM (Federal Institute for Materials Research and Testing) for not fully revealing the test set-up. Thus, tests cannot really be judged scientifically, EPA notes.
