A Carbon Footprint is Impacted by Fugitive Refrigerant Gas Emissions
A Carbon Footprint is Impacted by Fugitive Refrigerant Gas Emissions
The United States and a host of other foreign countries are focusing on fugitive emission tracking for certain industries. The goal is to identify the amount of substances that are emitted into the atmosphere when a refrigerant gas leak occurs. This will give government officials at the EPA a better understanding of the amount of greenhouse gases harming the environment each year and contributing to global warming due to the ineffective management of refrigerant gases.
Fugitive emission takes place when an unexpected leak of a hazardous substance occurs in a system and the discharge is not contained in a vent, stack, or duct. This may be caused by a component failure, poor servicing, or a breakdown in some industrial process. When a system containing refrigerant leaks, these high global warming potential substances cause damage to the atmosphere. Certain refrigerant gases are not broken down in the atmosphere and end up entering the stratosphere and destroying the protective ozone layer over time.
Across the U.S. economy, refrigerant gases or fugitive emissions equal over 300K tons of carbon dioxide each year. Other countries have similar or worse outputs. Many environmental regulations, such as The Montreal and Kyoto Protocols, exist to reduce the escape of harmful substances, like refrigerants, into the atmosphere over time. There are additional goals to reduce the potential for global warming in the near future and to improve air quality in the long term by reducing the emissions refrigerant gases.
A select few refrigerant gases have multiple detrimental effects on the environment. Not only are they ozone depleting substances but they are also chemicals with a high global warming potential (GWP) which places them into the category of greenhouse gases which lead to global climate change. For many reasons, it is important to effectively monitor, track, and report refrigerant gas usage.
The EPA has finalized its rules pertaining to any fugitive emission occurrence, whether through evaporation or a leak. The regulations apply to several industries, including existing and newly constructed facilities with systems using refrigerant gas in their workplace heating and cooling systems. Other industries are industrial chemical manufacturing, electric services, pulp and paper mills, and petroleum refinancing.
Tracking fugitive refrigerant gases is required by facilities owning or operating HVAC-R systems or by manufacturers who produce them. The EPA has identified a number of dangerous compounds, among them chloroflurocarbons, hydrofluorocarbons, methyl bromide, halons, methyl chloroform, and carbon tetrachloride.
A particular concern for fugitive emission problems is with refrigerant gas, because it contains chloroflurocarbons and hydrofluorocarbons, two primary contributors to the weakening of the ozone layer and the increase in greenhouse gas volumes. Furthermore, refrigerant gas is used across many industries in refrigeration and cooling units, ventilation and air conditioning systems, and fire protection systems.
When a fugitive emission occurs, businesses are required to track the refrigerant leak rates and report annul refrigerant usage it to the EPA. One of the primary emissions scopes, fugitive refrigerant gas emissions are an integral part of an organizations carbon management requirements. Of the utmost importance is the determination of the HVAC-R system that is leaking and the capturing of the service event detail related to fixing the leak. Systems containing refrigerant gases must be inspected by EPA certified technicians and all service events must be logged when refrigerants are handled.
The new fugitive emission regulations provide a more standardized approach to thresholds identified by the U.S. Clean Air Act at the direction of the EPA. These include continuous monitoring, tracking of leaks, and reporting of leak repair, and containment.
Web applications and specialized tools can increase an organization’s efficiencies related to HVAC-R system maintenance, improve accuracy of refrigerant inventories thus saving money, and turn manual processes into a centralized, automated work flow. Development firms who specialize in the area. They ensure compliance and reduce the likelihood of substantial fines.

Planet – Sell Your Laptops
Planet – Sell Your Laptops
We’re in this environmental mess because humans have exploited the earth for personal gain. However, you can sell your laptops, get some grocery money and still help the planet.
Steer clear of the attitude that everything is disposable after a few uses; do your part and extract the most out of your electronics. In carelessly tossing away our possessions, we are the reason that one more thing spends an eternity in a landfill. Electronics, including laptops, are one of the most significant sources of toxic heavy metals, including cadmium, lead and mercury, leaking into the soil, according to the Environmental Protection Agency.
Pollutants do no simply stay within the confines of the landfills, but are transported through waterways and through the air. When toxic metals travel upward during evaporation, these toxins contribute to acid rain, spreading the heavy metals for miles. Dr. Lorris G. Cockerham, former professor at University of Arkansas and researcher, wrote that build up of toxic heavy metals in animals damages their vital functions and hinders growth in plants, therefore irrevocably harms ecosystems.
The heavy metals seep into waterways and into our water sources. These heavy metals can enter our body through the ingestion of contaminated water, harming our bodies. Even a low concentration can harm us, according to James Girard, author and professor at the American University.
A solution? Sell your laptops to a recycler. When you sell your laptops, the laptop parts find new life with computer repair shops and wholesalers, avoiding certain doom in a landfill. Selling laptops is an easy process for the average time-constrained American worker. Search for “sell laptops” on the Internet. Locate a recycling company who will accept the laptops you are selling. Lastly, look for the V logo that signifies the company is verified organization, not a Nigerian scam. Many business will offer an instant quote on their Web site for the laptop you are selling. Input the specifications of your laptop, follow directions and you have check or a PayPal payment for your laptops.
Make sure you choose a reputable company to sell your laptops to. Some companies boast a “green” philosophy, but actually ship laptops to landfills in developing countries. We all have a part in this green earth and many of us have take steps to follow the mantra, “reduce, reuse and recycle.” Many people think about selling their cans, bottles and such and don’t think about their computers. Do your part, keep our Earth Green and sell your laptop.

What it Really Is: Recycling
What it Really Is: Recycling
Recycling has become the catch all phrase often used in place of the 3 R’s. But in its truest form recycling means taking one thing and changing it, usually chemically, into another. This is not to say that recycling is without value; it is certainly better than putting the items in the bin where they will end up in landfills and leach chemicals into our ground water. It is though to say that before you place anything in the recycle bag, first consider if you could reduce or re-use it, because everything that ends up in the recycling bag will have to be altered before it can be used again. Even then it is cleaner to produce goods from recyclables than from raw materials.
Here are just a few reasons to make certain that after you have reduced the amount of waste your create and re-used as many things as possible that your family puts as many things as possible into the recycling bins:
- Recycling one aluminium can saves enough energy to run a TV for three hours — or the equivalent of a half a gallon of gasoline.
- Each ton (2000 pounds) of recycled paper can save 17 trees, 380 gallons of oil, three cubic yards of landfill space, 4000 kilowatts of energy, and 7000 gallons of water. This represents a 64% energy savings, a 58% water savings, and 60 pounds less of air pollution!
- The 17 trees saved (above) can absorb a total of 250 pounds of carbon dioxide from the air each year. Burning that same ton of paper would create 1500 pounds of carbon dioxide.
- Recycling plastic saves twice as much energy as burning it in an incinerator.
- The energy saved from recycling one glass bottle can run a 100-watt light bulb for four hours. It also causes 20% less air pollution and 50% less water pollution than when a new bottle is made from raw materials.
- A modern glass bottle would take 4000 years or more to decompose — and even longer if it’s in the landfill.
Today is the actually a great day to talk about recycling. Each Thursday the council sends around men to collect our recyclables. The council gives us re-usable sacks, which we can use to collect all paper, cardboard, tin cans, aluminium, glass bottles and jars and plastic bottles. Unfortunately, they do not over recycling for other plastics. As I have been writing this series of blogs that has been one thing that I have been especially mindful of: how much plastic packaging manufacturers use that cannot be recycled and that it is estimated takes over 500 years to decompose in landfills.
But it is not just our plastics, glass, metals and paper that we recycle. Thanks to a wonderful programme through the Islington council, last year we were able to purchase a subsidized wormery to recycle our food waste into compost and liquid fertilizer for growing my own food. Actually, even though we may think that food thrown into the bin will degrade relatively quickly in the landfills, the biggest problem is the amount of methane, a dangerous green house gas, which it produces in that time. Methane is twenty times more potent than carbon dioxide and a major contribute to climate change. While my wormery cannot accommodate meat products I put all peels and unused fruits and vegetables into it. I should soon be harvesting my first patch of compost…just in time for my summer garden.
So how does my family do on recycling? Not too bad honestly. This week we had two bags of recyables and will only have two half full 13 gallon bin bags of other rubbish. Actually hubby and I got into a minor disagreement over the trash last night. One of the first rules of the 3R’s is to only throw out your garbage when the bag is full. In our case though, it had begun to smell. I am still looking for a solution…if anyone has ideas they would be greatly appreciated. But for a family of three adults and one pre-schoolers two large bags of recycling and one full 13 gallon bin bag in a week is pretty good I think. I imagine that there are single people, who put more than one bag in the bin each week.
