I want to know the answer to the following question:
How much CO2 emission would a 40-watt light bulb produce after 10 hours?
All the background I'm provided with is that "A building’s carbon footprint from lighting can therefore be reduced by 85% by exchanging all incandescent bulbs for new LEDs if a building previously used only incandescent bulbs.". Is that enough to answer the question?
Answer: no
