Indian Government Sets 20°C AC Temperature Limit: Will This Initiative Save Our Planet?

Hyderabad: The Indian government plans to regulate air conditioner temperatures, setting a minimum of 20°C and a maximum of 28°C. Manohar Lal Khattar, the Union Minister of Housing and Urban Affairs, emphasized that this "temperature standardization" is essential for conserving energy, especially during the hot summer months.

Why Regulate Air Conditioning?

Many people cool their spaces to frigid temperatures, like 16°C. This not only strains the electrical grid but also harms the environment. Air conditioners contribute to global warming because they use refrigerants that can emit harmful gases.

According to the International Energy Agency, there are about 2 billion air conditioners worldwide, with half of them in the US and China. Cooling systems consume around 20% of global building energy.

The Energy and Resources Institute (TERI) suggests that setting air conditioners to higher temperatures, like 27°C, can significantly reduce electricity consumption and costs. In fact, raising the temperature by just 1°C can cut electricity usage by 6%, leading to considerable savings. Moreover, a shift to a setting of 24°C could lower carbon emissions as well.

The Impact of Air Conditioning on CO2 Emissions

TERI highlights a critical finding: improving the efficiency of air conditioner systems in India could lower CO2 emissions by around 180 million metric tons by 2030. Currently, India adds 10-15 million new ACs each year, and this number is expected to rise. Without effective policy measures, air conditioning could drive up electricity demand dramatically.

Understanding Refrigerants

Historically, older ACs used chlorofluorocarbons (CFCs) that damaged the ozone layer. They’ve largely been replaced by hydrofluorocarbons (HFCs), which, while safer for the ozone, are potent greenhouse gases that contribute to global warming.

The Broad Effects of Air Conditioning on Climate

Air conditioning has significant effects on both climate and environment. The power these systems consume often comes from fossil fuels, which further adds to CO2 emissions. Notably, for every ton of CO2 released by cooling technologies, heating systems release four tons.

Global Context

Some countries have already implemented regulations on air conditioning. Here’s a look at a few:

• Italy: Minimum of 25°C in airports and hotels
• Greece: Minimum of 26°C in public spaces
• Spain: Minimum of 27°C in retail and cultural venues
• China: Minimum of 26°C in government facilities
• Bangladesh: Five-hour daily AC ban

These measures aim to strike a balance between comfort and environmental responsibility.

In summary, regulating air conditioning temperatures can lead to significant energy savings and lower emissions. As we grapple with climate change, these proactive steps are crucial for a sustainable future.
