In 2005, the UN's greenhouse gas reduction incentive program offered carbon credits for pollutant disposal, particularly HFC-23, a byproduct of HCFC-22 coolant. This strategy backfired as companies increased coolant production to earn more credits, driving down refrigerant prices, and consequently, refrigeration companies continued using it despite its environmental impact, prolonging its use. The European Union suspended HFC-23 destruction credits in 2013 to rectify the unintended environmental consequences.
