In 2018, global commercial operations generated 2.4% of all CO 2 emissions. [3] Jet airliners have become 70% more fuel efficient between 1967 and 2007, and CO 2 emissions per revenue ton-kilometer (RTK) in 2018 were 47% of those in 1990. In 2018, CO 2 emissions averaged 88 grams of CO 2 per revenue passenger per km.
Gas turbines are also more resistant to corrosive damage than RP engines. Gas turbines need a minimum of 1,300 cfm and typically exceed 2,100 cfm and can generate 1 to 10 MW. A gas turbine (greater than 3 MW) can typically cost $1,400 per kW with annual operation and maintenance costs of $130 per kW. [9] Estimates are in 2010 dollars.
An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).
Fuel economy in aircraft. Between 1950 and 2018, efficiency per passenger grew from 0.4 to 8.2 RPK per kg of CO₂. [ 1 ] The fuel economy in aircraft is the measure of the transport energy efficiency of aircraft. Fuel efficiency is increased with better aerodynamics and by reducing weight, and with improved engine brake-specific fuel ...
The carbon dioxide equivalent (CO 2 e or CO 2 eq or CO 2-e or CO 2-eq) can be calculated from the GWP. For any gas, it is the mass of CO 2 that would warm the earth as much as the mass of that gas. Thus it provides a common scale for measuring the climate effects of different gases. It is calculated as GWP times mass of the other gas.
It is the process of quantifying raw material and energy requirements, atmospheric emissions, land emissions, water emissions, resource uses, and other releases over the life cycle of a product or process. [30] In other words, it is the aggregation of all elementary flows related to each unit process within a product system.
Continuous emission monitoring systems (CEMS) are used as a tool to monitor the effluent gas streams resulting from combustion in industrial processes. CEMS can measure flue gas for oxygen, carbon monoxide and carbon dioxide to provide information for combustion control in industrial settings. [1][2] They are also used as a means to comply with ...
R&D GREET (Research and Development Greenhouse gases, Regulated Emissions, and Energy use in Technologies) is a full life cycle model sponsored by the Argonne National Laboratory (U.S. Department of Energy 's Office of Energy Efficiency and Renewable Energy). It fully evaluates energy and emission impacts of advanced and new transportation ...
