1 HFC and Global Warming Presented by Mohammad Reazuddin
Capacity Building Workshop on HFC Phase Down : An Initiative to Reduce Global Warming Date: 18 October 2016 Venue: The Daily Star Conference Room, Dhaka. HFC and Global Warming Presented by Mohammad Reazuddin

2 List of GHGs and ODSs GHGs ODSs Carbon dioxide CFCs Methane Halons
Fluorinated gases Methyl bromide Nitrous Oxide HCFCs Carbon tetrachloride

3 Amendments of Montreal Protocol
Who Controls What? ODSs Vienna Convention Montreal Protocol Amendments of Montreal Protocol Kigali Amendment GHGs UNFCCC Kyoto Protocol Paris Agreement

4 Interaction of GHGs and ODSs

5 Is there any interaction between climate protocols and ozone protocol?

6 How did Montreal Protocol attain the success?
Phasing out of CFCs and HCFC Now, replacing HCFCs by HFCs Ultimately it has saved the ozone layer but harming the climate

7 HFC are under now dual control

8 What are HFC and where they are used?
HFCs are hydro fluorocarbons. About 3,800 times more potent than CO2 with a lifetime of 14 years Uses Refrigeration and air-conditioning Foam Solvent Fire fighting Aerosol MDI etc.

9 Use of HFCs in Bangladesh
Domestic Refrigeration Manufacturing Commercial/Industrial Refrigeration Manufacturing Industrial air-conditioning including chillers Transport Refrigeration manufacturing Residential Air-conditioner manufacturing Commercial/ Industrial Chiller manufacturing Mobile Air-conditioner manufacturing Fire Extinguishers manufacturing Pharmaceutical Applications (MDIs) Service sector (for all applications)

10 Projections of HFCs Use

11 The potential threat of HFCs and global warming
Currently it is around 2% of total GHG emission in terms of CO2 equivalent Within next 20 to 30 years, it is projected to occupy around 20% of the total GHG emission, if HFC uses are continued as business usual

12 Climate friendly alternatives of HFCs and HCFCs
Hydrocarbons HFOs Not in kind technology Ammonia carbon dioxide etc.

13 Barriers and constraints
Technology transfer Capacity building Financing SMEs? MDI

14 Thanks
