The total carbon emissions for a flight from New York, New York to Sydney, Australia is 3,722 lbs CO2.
This is equivalent to 1,688 kg CO2e or 1.69 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 10,050 pounds, equivalent to 4,559 kilograms or 4.56 metric tonnes.
These calculations are based on the distance from New York, NY to Sydney, Australia, which is 9,934 miles or 15,988 kilometers.
Your trip begins in New York, New York.
It ends in Sydney, Australia.
This trip is a long haul international flight. The calculation includes an assumption of a 79.7% load factor with 346 seats on the B747-400 and 261 seats on the B767-300ER.
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.
