Climate Change: CO2 is Not the Only Gas Attack
How is your company air-conditioning its buildings? It may be the equipment it’s using is unsustainable, even though it complies with today’s environmental regulations. Although CO2 is by far the most common greenhouse gas (gasses that are trapped in the earth’s atmosphere which retain more heat from the sun), there are other, more potent greenhouse gasses with a defined Global Warming Potential (GWP). Methane, for example, has a GWP of 40, meaning that one Tonne of methane in the atmosphere has the same greenhouse effect as 40 Tonnes of CO2. The chemical Hydroflurocarbon (HFC) has a GWP of 2,000 and is in common use in air conditioning and refrigeration systems. Ironically these gasses were introduced to replace the ozone depleting…
