Greenpeace has urged India to ban incandescent light bulbs and switch to more energy efficient options in order to reduce greenhouse gas emissions by four percent. India is currently one of the top five polluters in the world, alongside the United States, China, Russia, and Japan. Experts predict that India's carbon emissions will triple by 2050 due to rapid economic development and population growth, making it crucial for the country to focus on becoming more energy efficient. One way to reduce greenhouse gas emissions is by replacing incandescent bulbs with compact fluorescent lights (CFLs), which use less energy and can cut emissions by four percent. Experts warn that unchecked emissions could lead to a rise in temperatures between 1.8 and 4.0 degrees Celsius in the 21st century. The Indian subcontinent is expected to be heavily impacted by global warming, leading to more frequent and severe natural disasters, increased disease, and hunger. CFLs may be more expensive than traditional incandescent bulbs, but they use 80 percent less energy, saving households and industries money. In India, approximately 20 percent of electricity is used for lighting, and switching to CFLs could help meet the country's growing power needs. Australia was the first country to announce in February that it would ban light bulbs, with plans to phase them out within three years. 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 is still relatively low, making up only 10 percent of the world's market share for light sources. Greenpeace noted that India currently uses 640 million incandescent light bulbs annually, while only 12 million CFLs are in use.
