Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby, based on the constant creation ...
Carbon-14. Carbon-14, C-14, 14C or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic matter is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Carbon-14 was ...
Greenhouse gas inventories are emission inventories of greenhouse gas emissions that are developed for a variety of reasons. Scientists use inventories of natural and anthropogenic (human-caused) emissions as tools when developing atmospheric models. Policy makers use inventories to develop strategies and policies for emissions reductions and ...
Carbon accounting. Depiction of carbon accounting using the WRI-Greenhouse Gas Protocol classification of emissions into three categories: Scope 1, 2, and 3. Additional downstream Scope 3 sources are shown on WRI's website. [1][2] Carbon accounting (or greenhouse gas accounting) is a framework of methods to measure and track how much greenhouse ...
The Sustainability Accounting Standards Board (SASB) is a non-profit organization, founded in 2011 by Jean Rogers [1] to develop sustainability accounting standards. Investors, lenders, insurance underwriters, and other providers of financial capital are increasingly attuned to the impact of environmental, social, and governance (ESG) factors on the financial performance of companies, driving ...
An environmental profit and loss account (E P&L) is a company's monetary valuation and analysis of its environmental impacts including its business operations and its supply chain from cradle-to-gate. An E P&L internalizes externalities and monetizes the cost of business to nature by accounting for the ecosystem services a business depends on ...

Armed with the results of carbon-dating the tree rings, it became possible to construct calibration curves designed to correct the errors caused by the variation over time in the 14 C / 12 C ratio. [4] These curves are described in more detail below. There are three main reasons for these variations in the historical 14 C / 12
