The EPA has decided to drastically cut potent greenhouse gases. The EPA says these chemicals, like hydro fluorocarbons (HFCs) and per fluorocarbons (PFCs), cause global warming by trapping heat in the Earth's atmosphere. HFCs are used in air conditioners and refrigerators, while PFCs are used in the foam of every airplane and car. There is a four year grace period for companies that use these chemicals to adapt. Many people believe this action is too late, as measures to combat global warming should have been put in place a long time ago. It aims to reduce HFC production and usage in the United States by 85 percent over the next 15 years as part of a global phase out to combat global warming. By 2050, it is predicted to reduce harmful emissions by the equivalent of 4.5 billion metric tons of CO2, which is equivalent to three years' worth of emissions from the US power sector. Over the next 30 years, switching to safer alternatives and more energy-efficient cooling systems is estimated to save more than $270 billion in costs and improve public health.

The EPA also plans on prohibiting the manufacturing of these chemicals within the U.S., but this ban doesn't take effect until 2023. This gives companies that currently use these chemicals five years to conform to the regulations. Many people have mixed opinions about this ban. Some think that it is a wonderful idea, while others are upset with these changes. It is giving companies years to adapt, but some people say this isn't enough time. Although the ban doesn't take effect until five years from now. Air conditioners could be a lot more efficient without these chemicals. Air conditioners use a lot of energy to produce enough cold air for a room, and many people think that if these chemicals are taken out of the picture, then these machines won't have to work as hard at cooling down an area.

This ban could bring about new technology that will help air conditioners work more efficiently. It could also lower the price of these machines, so more people can afford them. There are many positives to this ban, especially in regards to helping the environment. However, air conditioner companies are worried because they just aren't sure how they will be able to create these machines without these chemicals. It is still too early for them to know, but they are certainly thinking about it.
