Total Equivalent Warming Impact or (TEWI)
TEWI
The Global Warming Potential (GWP) of refrigerants takes into account both their direct and indirect effects on global warming. Direct effects refer to the greenhouse gas emissions from the refrigerants themselves, while indirect effects involve the emissions associated with the energy used to produce and operate refrigeration systems. GWP provides a metric for comparing the climate impact of different refrigerants over a specified time frame, typically 100 years, allowing for informed decisions in refrigeration technology and policy.
Concurrent with the concern over ozone depletion is concern over global warming, which has generally been attributed to carbon dioxide emissions but also to emissions of certain refrigerants and methane.
Hydrocarbons, such as propane and isobutane, are considered to have the least impact on the environment as refrigerants. They have low Global Warming Potential (GWP) and Ozone Depleting Potential (ODP), making them more environmentally friendly options compared to other refrigerants like Trichlorofluoromethanes (CFCs) and Chlorodifluoromethanes (HCFCs).
Global warming is a direct threat to biodiversity because it can directly impact ecosystems through changes in temperature, precipitation patterns, and sea levels, which can result in habitat loss, shifts in species distributions, and increased extinction risks for many species.

Refrigerants must not be vented into the atmosphere because they are harmful to the environment. When released, they contribute to ozone depletion and global warming. Proper disposal or recycling of refrigerants is necessary to prevent adverse effects on the environment.
We can stop using CFC gases which are used in refrigerants and air conditioners which are responsible for its depletion. In this way we can stop global warming.
Eco-friendly refrigerants are substances used in refrigeration and air conditioning systems that have a lower impact on the environment. They have low global warming potential (GWP) and zero ozone depletion potential (ODP). Examples of eco-friendly refrigerants include hydrofluorocarbons (HFCs) with lower GWP, natural refrigerants like carbon dioxide (CO2), ammonia (NH3), and hydrocarbons like propane (R290) and butane (R600). These refrigerants help to reduce greenhouse gas emissions and protect the ozone layer.
Chlorine-free refrigerants are typically classified as hydrocarbons or natural refrigerants, such as R-290 (propane) or R-600a (isobutane). These alternatives are considered more environmentally friendly compared to traditional synthetic refrigerants that contain chlorine, such as CFCs and HCFCs. They have lower global warming potentials and ozone depletion potential.
Ozone depletion can be stopped by substitutuing refrigerants with some other gases. It will help stop Global Warming too.
Recovering refrigerant is necessary to prevent environmental harm because refrigerants can deplete the ozone layer and contribute to global warming. It is also required by law in many places to properly handle and dispose of refrigerants to protect the environment and public health.

The transportation industry is moving to new refrigerants with lower global warming potential (GWP) to mitigate the environmental impact of greenhouse gas emissions. These new refrigerants help reduce the industry's contribution to climate change by decreasing the amount of heat-trapping gases released into the atmosphere. Additionally, regulatory policies are pushing for the adoption of more environmentally friendly refrigerants in an effort to meet sustainability goals and reduce carbon footprint.
The newer refrigerant in use today is typically HFC (Hydrofluorocarbon) refrigerants such as R-410A or R-134a. These refrigerants have been introduced as alternatives to phased-out HCFCs and CFCs due to their lower impact on ozone depletion and global warming.
