Environmental Protection Agency’s GreenChill Program recognized 12 food retail companies and one manufacturer of advanced refrigeration systems for their exceptional achievements to reduce the use of ozone-depleting substances and/or climate-damaging refrigerants.

volume mixing ratio), together with a number of trace gases, such as argon (0.93% volume mixing ratio), helium, radiatively active greenhouse gases such as carbon dioxide (0.035% volume mixing ratio), and ozone. Fluorinated gases are sometimes used as substitutes for stratospheric ozone-depleting substances (e.g.,

For some parts of the spectrum, the IR can be either absorbed by CO 2 or by water vapour or by clouds, but taking those overlaps into account we find that 50% of the greenhouse effect is from water vapour, 25% from clouds, and about 20% from CO 2 and the rest absorbed by ozone, aerosols, and other trace gases ( Schmidt et al, 2010 ).

Carbon dioxide (CO 2 ) is the most important greenhouse gas that we have added to the atmosphere, however, some of it has been absorbed by land and oceans. In addition, ozone depletion higher up in the stratosphere has caused a cooling high up in the atmosphere. This is likely an effect of man-made climate change.

Even if there is water available, heat waves can cause the water sources to be too hot, which can reduce the plant’s efficiency or even cause unsafe operating conditions because the plant can’t be adequately cooled. EPA has already finalized a rule that aims to address interstate ozone pollution , dubbed the Good Neighbor Plan.
