Kigali Resurfaces

Kigali Resurfaces

Kigali is an amendment to the Montreal Protocol that will ban chemicals used as refrigerants which emit CO2 and, supposedly, have a large affect on climate change.

These will replace chemicals currently used in air-conditioning and refrigeration that do not harm the Ozone layer… but do emit CO2.

The Kigali agreement, which is binding and has sanctions for violating it, was agreed to in 2016, with support from the United States. See my 2016 article, Air Conditioning as Dangerous Climate Threat.

The Kigali amendment has been ratified by over 50 countries and went into effect on January 1, of this year.

However, the Kigali agreement has not yet been ratified by the US Senate so the United States is not yet subject to the agreement. However, it undoubtedly will be ratified if supporters of the Green New Deal ever control the Senate.

Please note, there are no safe alternatives to the chemicals that will be banned.

Growing up in New York City, I remember having to evacuate our apartment because a refrigerator using ammonia in an apartment above us had suffered a leak.

Ammonia is one of the chemicals that can be used as a refrigerant under the Kigali agreement. CO2 can also be used but it requires much higher pressures resulting in expensive air-conditioning units.

Virtually all other possible refrigerants are fire hazards.

Recently the Kigali agreement has resurfaced and received support from members of congress.

The reason for this support is that ratification by the US may increase exports of air-conditioning and other equipment to countries subject to the amendment, and this might create jobs. Without ratification, exports and jobs may be lost.

But ratification will have negative effects on all Americans.

First, the cost of air-conditioning equipment and refrigerators are likely to increase.

Second, Americans will be exposed to fire and health hazards unless a new chemical refrigerant is developed.

Ratification will not benefit the Ozone layer since the chemicals currently used in air-conditioning and refrigerators do not affect it.

The only reason for the Kigali agreement is to cut CO2 emissions.

Once again, climate change hysteria is having a negative effect on Americans, and everyone else as well.

  1. What refrigerants are you referring to that emit CO2 by the comment:
    “chemicals currently used in air-conditioning and refrigeration that do not harm the Ozone layer… but do emit CO2”

    There are several possible elemental combinations among Cl, F, and C in these earlier and present compounds, and essentially all of them can absorb IR radiation at a variety of wavelengths across ~8-10 microns. Another issue is that apparently less absorbing Cl-F-C compounds can undergo various reaction changes in the stratosphere under influence of solar radiation, producing more IR absorbing compounds.

    • Hydrofluorocarbons (HFCs)
      Supposedly, a “kilogram of the most common HFC in air conditioning is 2,000 more potent as a greenhouse gas than a kilogram of carbon dioxide.”
      I’m not a chemical engineer so I’m basing my comments on what I have read.
      I used the word emit, which is technically inaccurate. The chemical results in the formation of CO2 in the atmosphere.
      I should have been clearer in that regard.
