For example, purchase of star rated ACs can reduce electricity consumption and carbon footprint.
However, the impact of this star rating will be lost if the individual household uses the ACs at very low temperature for significant number of hours.
This is where the behavioural change must come in.The use of non-motorized transport or avoidance of transport is another important approach.
As much as an individual reduces to travel that much of air pollution and GHG emission can be saved.
Instead of travelling to a distant place to purchase foods and home needs, the individual can choose to buy them in nearby shops.
One practice getting popular is the home gardening to grow flowers and vegetables from one’s own terrace space.
