Homework for Sept 25th: Reflection on finding a local climate friendly super market:
One of my actions was to do research on a climate friendly super market near me. Specifically, a super market that has sustainable refrigerant management, meaning that the store does not use HFC refrigerants. Truthfully, I had no grasp of the impact that refrigerants have on the environment until just now. After doing some reading, I'm shocked to hear that the use of Hydrofluorocarbons, which have a large impact on global warming, are used almost universally today. These HFC's were implemented as an alternative to chlorofluorocarbons and hydrochlorofluorocarbons, which deplete the ozone layer. While HFC's do not deplete the ozone layer, their usage, as well as their release during production or leakage, continues to contribute to global warming. While there are more economically friendly options, stores that use them are scarce. I was even more shocked to find that the climate friendly supermarket map shows that there are zero supermarkets on the island of Montreal that have replaced HFC's with natural refrigerants. The "What You Can Do" column of Project Drawdowns refrigerant management page recommends purchasing a high efficiency refrigerator if you're in the market or recycling units so that the refrigerant can recover, for those curious about how to help. Ultimately, there is not much I can do at the moment, other than making a post like this to spread awareness. I am not in the market to buy a refrigerator, nor am I getting rid of one. However now that I have learned more about the issues with HFC and leaks, I will be able to make a more educated decision when buying one in the future.
