Greenhouse gas (GHG) is a gas in the atmosphere that absorbs and emits radiation within the thermal infrared range. This process by which greenhouse gases trap heat in an atmospheric layer is also called the greenhouse effect or sometimes simply greenhouse. Greenhouse gases contribute to the warming of our atmosphere because they absorb the energy from sunlight and warm-up, rather like a greenhouse does.

Have you ever noticed when you're drinking an ice-cold drink on a hot summer day, the outside of your glass is wet? This is because the air around the glass cooled, and water from the air condensed onto the glass; this is the dew point temperature.

When working with natural gas compression and similar equipment, it is inevitable to produce methane emissions. In addition, the growing production and utilization of natural gas in Canada has undoubtedly increased methane production.
