The total carbon emissions for a flight from Chicago, Illinois to Kolt, Denmark is 1,560 lbs CO2.
This is equivalent to 708 kg CO2e or 0.71 tonnes of carbon dioxide equivalents.
With radiative forcing in effect, the carbon emissions may increase by 2.7 times, so the CO2 equivalents would then be 4,213 pounds, equivalent to 1,911 kilograms or 1.91 metric tonnes.
These calculations are based on the distance from Chicago, IL to Kolt, Denmark, which is 4,164 miles or 6,702 kilometers.
Your trip begins in Chicago, Illinois.
It ends in Kolt, Denmark.

Travelmath provides an online carbon emissions calculator to help you find the CO2 footprint of any flight. You can enter airports, cities, states, countries, or zip codes to compute the CO2 emissions between any two locations. The distance is calculated using a GPS-accurate method and the approximate carbon emissions are shown in pounds, kilograms, and metric tonnes. You can view the effects of radiative forcing and other variables on the measure of carbon dioxide equivalents (CO2e). Formulas are based on the UK DEFRA specifications for domestic, short haul, and long haul international flights. Carbon emissions due to airline travel can impact climate change, so it's important for us to look for eco-friendly ways to help the environment and leave a greener world for the next generation. You can do your part by learning how to go green--through recycling and conserving natural resources, promoting clean air and water, purchasing carbon offsets to reduce your personal footprint, and encouraging your company to take part in corporate sustainability.
