CO2 Ticker – Saving CO2 with OSRAM products
1
1 kg CO2
What is CO2?
CO2 is a greenhouse gas largely produced by burning fossil fuels such as oil, gas and coal - for example when they are used in power plants to generate electricity. These greenhouse gases accumulate in the atmosphere in ever increasing concentrations, causing a growing proportion of solar energy to be trapped in the atmosphere rather than being reflected back into space.
In total, 19 percent of generated electricity worldwide is used for the purpose of artificial lighting. And around one third of this is consumed by ordinary light bulbs, even though there have been better alternatives available for years.
Background to the CO2 Ticker [1]
The CO2 Ticker indicates the achievable energy savings with more efficient lighting technologies like compact fluorescent lamps. The calculation is based on a direct comparison to ordinary incandescent light bulbs regarding the respective lifetime of the lamp types.
The energy savings per lamp type are multiplied with historic and target sales figures. Certain simplifications have had to be made, such as reducing the historic values to main types and linearizing the target sales. The total energy savings calculated this way are converted into savings of CO2 emissions based on an energy mix of 0.5 kg of CO2 per kilowatt hour.
[1] The CO2 Ticker contains forward-looking statements and information. These statements are based on our current expectations and certain assumptions, and are therefore subject to certain uncertainties. A variety of factors, many of which are beyond the control of OSRAM, affect the figures used as a basis. OSRAM does not guarantee the correctness of these figures.
