How much Co2 does an average google search create?<|im_end|>
<|im_start|>assistant
In terms of greenhouse gases, one Google search is equivalent to about 0.2 grams of CO2. As a reference, the current EU standard for tailpipe emissions calls for 140 grams of CO2 per kilometer driven, but most cars don't reach that level yet.<|im_end|>

How was that calculated?<|im_end|>
<|im_start|>assistant
The calculation for the amount of CO2 created by a single Google search was determined by looking at the cumulative net global anthropogenic CO2 emissions up to date and estimating the amount of CO2 created by the energy used for a typical search. This estimate was then used to calculate that a single Google search produces an estimated 0.2 grams of CO2.<|im_end|>
