Greenpeace is urging India to prohibit the use of incandescent light bulbs and switch to more energy efficient lighting options in order to reduce the nation's greenhouse gas emissions by four percent. India is currently one of the top five polluters in the world, alongside countries like the United States, China, Russia, and Japan, and experts predict that its carbon emissions will triple by 2050 due to rapid economic growth and population increase. Greenpeace's climate change campaigner, K. Srinivas, emphasized the importance of India becoming more energy efficient in light of these projections. One method to combat greenhouse gas emissions is by replacing incandescent bulbs with compact fluorescent lights (CFLs), which use less energy and can reduce emissions by four percent. Experts warn that unchecked emissions could lead to a temperature increase of 1.8 to 4.0 degrees Celsius in the 21st century, with the Indian subcontinent being severely impacted. This could result in more frequent and severe natural disasters, increased disease, and hunger. Despite being more expensive than traditional incandescent bulbs, CFLs use 80 percent less energy and can save households and industries money. Srinivas stated that approximately 20 percent of electricity in India is used for lighting, and switching to CFLs could help meet the country's growing power demands. In February, Australia made headlines by becoming the first country to announce a ban on light bulbs, with plans to phase them out over a three-year period. Environmentalists have raised concerns about the mercury content in CFLs, warning that improper disposal could pose serious health risks due to the toxicity of the heavy metal. Despite these concerns, global demand for CFLs remains low, making up just 10 percent of the world's market share for light sources. Greenpeace noted that India, for example, uses 640 million incandescent light bulbs annually, far outnumbering the 12 million CFLs in use.
