The greenhouse gas protocol is a set of standards for tracking greenhouse gas emissions. [17] The standards divide emissions into three scopes (Scope 1, 2 and 3) within the value chain. [18] Greenhouse gas emissions caused directly by the organization such as by burning fossil fuels are referred to as Scope 1.
This is an accepted version of this page This is the latest accepted revision, reviewed on 9 December 2024. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
Greenhouse gas emissions can be divided into those that arise from the combustion of fuels to produce energy, and those generated by other processes. Around two thirds of greenhouse gas emissions arise from the combustion of fuels. [108] Energy may be produced at the point of consumption, or by a generator for consumption by others. Thus ...
Carbon accounting (or greenhouse gas accounting) is a framework of methods to measure and track how much greenhouse gas (GHG) an organization emits. [3] It can also be used to track projects or actions to reduce emissions in sectors such as forestry or renewable energy .
The R&D GREET model is specified in the Inflation Reduction Act of 2022 §45V [1] as the methodology to calculate the life cycle greenhouse gas emissions "through the point of production (well-to-gate)" when determining the level of tax credit for clean Hydrogen production until a successor is approved by the Secretary of the Treasury.
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).
An emission inventory (or emissions inventory [1]) is an accounting of the amount of pollutants discharged into the atmosphere.An emission inventory usually contains the total emissions for one or more specific greenhouse gases or air pollutants, originating from all source categories in a certain geographical area and within a specified time span, usually a specific year.
Percentage change in the four parameters of the Kaya Identity, which determine total CO₂ emissions. The Kaya identity is a mathematical identity stating that the total emission level of the greenhouse gas carbon dioxide can be expressed as the product of four factors: human population , GDP per capita , energy intensity (per unit of GDP), and ...
