In the context of GHG accounting, RECs are often used to adjust estimated Scope 2 emissions. In a typical case, a company would calculate its Scope 2 emissions using its electricity consumption and a grid emissions factor. Companies that purchase RECs can use them to lower the average emissions factors included in their inventories.
The GHG Protocol Corporate Standard (GHG Protocol Corporate Accounting and Reporting Standard, GHGPCS) is an initiative for the global standardisation of emission of greenhouse gases in order that corporate entities should measure, quantify, and report their own emission levels, so that global emissions are made manageable.
The emissions information in eGRID include carbon dioxide (CO 2), nitrogen oxides (NO x), sulfur dioxide (SO 2), mercury (Hg), methane (CH 4), nitrous oxide (N 2 O), and carbon dioxide equivalent (CO 2 e). CO 2, CH 4, and N 2 O are greenhouse gases (GHG) that contribute to global warming or climate change.
ISO 14064-3:2019 specifies principles and requirements and provides guidance for those conducting or managing the validation and/or verification of greenhouse gas (GHG) assertions. It can be applied to organizational or GHG project quantification, including GHG quantification, monitoring and reporting carried out in accordance with ISO 14064-1 ...
Additionally, the treatment of emissions results in residues that require proper handling for recycling or final disposal (for instance, the pollution abatement process of sulfur dioxide involves its conversion into gypsum or sulfuric acid). To address these complexities, Nakamura and Kondo extended the standard EEIO model by incorporating ...
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.
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.
For example, to estimate emissions from the energy sector (typically contributing over 90% of CO 2 emissions and 75% of all GHG emissions in developed countries) the quantity of fuels combusted is combined with an emission factor - the level of sophistication increasing with the accuracy and complexity of the emission factor.
