Only split ACs leak.

"Nearly 66% of live births in 2023 were first-order births - a terminology used to refer to the first born - and just 3.6% accounted for forth or higher order births, according to Sample Registration System (SRS) Statistical Report 2023. In terms of spacing of births, it stated, 53.6% of second and higher order births occurred 36 months or more after the previous live birth." TOI. "India's overall TFR (Total Fertility Rate) touched and then fell below the critical 2.1 threshold in 2019 and 2020." Urban TFR reached 1.5 in 2023 while the rural TFR "has fallen more sharply, from 3.3 in 2004 to 2.1 in 2023." "According to the United Nations' 2024 population projections, the growth rate of India's population has already slowed down from a CAGR of 2.33% in 1950-60 to 0.98% in 2015-25, and it will start declining from 2062," wrote Abhishek Jha & Roshan Kishore. Since human beings are solely responsible for global warming and pollution only a drastic reduction in human population will clean up the world. As TFR falls and disposable wealth rises the use of refrigerators, room air-conditioners (RACs) and motor vehicles rises. "The sale of RAC's has been growing 15-20% annually since 2020." And "The coolants we use today - hydrofluorocarbons (HFCs) - are hundreds of times more potent than carbon dioxide (CO2) in heating the climate." "In India, refrigerant leakage has crisis proportions," wrote Chandra Bhushan. Leakage of coolant gas can happen due to faulty Shrader valve, manufacturing defects, corrosion of coils and formicary corrosion. croma.com. All articles analysing the reasons for leakage of coolants fail to mention the main, and perhaps the only, reason for leakage - split ACs. Refrigerators and window ACs almost never leak even after ten years of use because they are factory fitted. Only split ACs leak probably because the internal and external units come separately and have to be linked through a hole in the wall during installation. So it has to be a basic fault in the design. "In the hurry to achieve climate goals, reduce dependence on fossil fuels, and claim self-reliance, govt's accelerated push for ethanol blended fuel - without giving vehicle makers, service providers, or consumers a longer period to transition smoothly - feels like a policy ambush." "Ethanol burns faster than petrol, delivers about 34% less energy per unit, and is corrosive because it absorbs water. Brazil's flex-fuel vehicles (FFVs), re-engineered to run on ethanol, are built to counter these drawbacks and reassure buyers that their cars will last while maintaining performance," wrote Anjana Menon. Using ethanol increases earning of farmers and apparently will improve acceleration of vehicles and act as anti-knocking. Reduced mileage and engine damage are due to bad driving and poor maintenance. pib.gov.in. There are only 50 million cars on Indian roads, that is 34 cars per 1,000 people. Data for India. On the other hand, there are hundreds of millions of farmers who constitute the largest vote-bank (wikipedia). Car owners will lose money. Farmers gain. Car owners can lump it.
