Your AC unit is hurting the planet (and your wallet). Here's how to fix that

If households around the world stop using poorly made air conditioning units and ACs are manufactured twice as efficiently as they are now, this would make a significant contribution to keeping to the Paris Agreement’s targets of a global temperature rise of 1.5C by 2050, according to a new UN report.
Air conditioning plays an important part in many climates — and that’s only going to increase with rising temperatures. But as the United Nations reports:
Many air-conditioning units emit carbon dioxide, black carbon, and hydrofluorocarbons (which have thousands of times the warming potential of carbon dioxide), and increasing demand for cooling is contributing significantly to climate change.
If we improve that:
The Cooling Emissions and Policy Synthesis Report, from the United Nations Environment Programme (UNEP) and the International Energy Agency (IEA), shows that up to 460 billion tonnes of greenhouse gas emissions — roughly the amount produced over an eight-year period — could be cut over the next four decades.
Countries can implement minimum energy performance standards, introduce building codes that ensure homes and offices are well insulated and require less cooling, and make temperature-controlled food supply chains more efficient and sustainable.
Sixty-five countries ratified the Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer, which came into affect on January 1, 2019. It will reduce the projected production and consumption of hydrofluorocarbons (HFCs), which are used in AC units, by more than 80% over the next 30 years. This can can avoid up to 0.4C of global warming by the end of this century.
