The American Denial of Global Warming - Perspectives on Ocean Science. Global Warming 101. Environmental impact of aviation - Wikipedia, the free encyclopedia. [ edit ] Total climate effects In attempting to aggregate and quantify the total climate impact of aircraft emissions the Intergovernmental Panel on Climate Change (IPCC) has estimated that aviation’s total climate impact is some 2-4 times that of its direct CO 2 emissions alone (excluding the potential impact of cirrus cloud enhancement). [ 9 ] This is measured as radiative forcing .
While there is uncertainty about the exact level of impact of NO x and water vapour, governments have accepted the broad scientific view that they do have an effect. Globally in 2005, aviation contributed "possibly as much as 4.9% of radiative forcing. " [ 16 ] UK government policy statements have stressed the need for aviation to address its total climate change impacts and not simply the impact of CO 2 . [ 18 ] The IPCC has estimated that aviation is responsible for around 3.5% of anthropogenic climate change, a figure which includes both CO 2 and non-CO 2 induced effects. Should aviation fuel for domestic and international flights be taxed to combat climate change. How much fuel does an international plane use for a trip. A plane like a Boeing 747 uses approximately 1 gallon of fuel (about 4 liters) every second.
Over the course of a 10-hour flight, it might burn 36,000 gallons (150,000 liters). According to Boeing's Web site, the 747 burns approximately 5 gallons of fuel per mile (12 liters per kilometer). This sounds like a tremendously poor miles-per-gallon rating! But consider that a 747 can carry as many as 568 people. Globalwarming.markey.house.gov/files/LTTR/ACES/IntlAirTransportAsscn.pdf. Mitigation of aviation's environmental impact. Emissions from aviation are continuing to grow despite advances in aircraft efficiency.
Currently 2% of global emissions are created by the aviation industry. At present aviation accounts for 2% of global CO2 emissions and this is projected by the IPCC to rise to 3% by 2050. [5] This presents the operators of aircraft with a responsibility to reduce emissions.
