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.
An oil or gas resource refers to known (discovered fields) or potential accumulations of oil and/or gas ( i.e undiscovered prospects and leads) in the subsurface of the Earth's crust. All reserve and resource estimates involve uncertainty in volume estimates (expressed below as Low, Mid or High uncertainty), as well as a risk or chance to exist ...
Gas storage facilities are gaining more importance due to changes in natural gas demands. First, traditional supplies that once met the winter peak demand are now unable to keep pace. Second, there is a growing summer peak demand on natural gas, due to electric generation via gas fired power plants. Datasource.
Calibration gas. A calibration gas is a reference gas or gas mixture used as comparative standard in the calibration of analytical instruments, like gas analysers or gas detectors. Therefore, a calibration gas has to be of a precisely defined nature or composition, like zero gas or span gas, for example 500 ppm carbon monoxide in nitrogen.
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules ( 1 gigacalorie ), [ 1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
Liquefied petroleum gas, also referred to as liquid petroleum gas (LPG or LP gas), is a fuel gas which contains a flammable mixture of hydrocarbon gases, specifically propane, n-butane and isobutane. It can sometimes contain some propylene, butylene, and isobutene. [1] [2] [3] LPG is used as a fuel gas in heating appliances, cooking equipment ...
United States Treasury securities, also called Treasuries or Treasurys, are government debt instruments issued by the United States Department of the Treasury to finance government spending, in addition to taxation. Since 2012, the U.S. government debt has been managed by the Bureau of the Fiscal Service, succeeding the Bureau of the Public Debt .
A carbon footprint (or greenhouse gas footprint) is a calculated value or index that makes it possible to compare the total amount of greenhouse gases that an activity, product, company or country adds to the atmosphere. Carbon footprints are usually reported in tonnes of emissions ( CO 2 -equivalent) per unit of comparison.
