The figures estimate average concentrations of chemical elements in the soils of more than 300 cities and settlements in Europe, Asia, Africa, Australia, and America. [1] Regardless of significant differences between abundances of several elements in urban soils and those values calculated for the Earth's crust, the element abundances in urban ...
The abundance of the chemical elements is a measure of the occurrences of the chemical elements relative to all other elements in a given environment. Abundance is measured in one of three ways: by mass fraction (in commercial contexts often called weight fraction), by mole fraction (fraction of atoms by numerical count, or sometimes fraction of molecules in gases), or by volume fraction.
Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of atomic number; [5] siderophiles shown in yellow. Graphs of abundance against atomic number can reveal patterns relating abundance to stellar nucleosynthesis and geochemistry.
Accordingly, a proportion of the CO 2 produced and reported in Asia and Africa is for the production of goods consumed in Europe and North America. [14] Greenhouse gases (GHG) – primarily carbon dioxide but also others, including methane and chlorofluorocarbons – trap heat in the atmosphere, leading to global warming.
Global map of greenhouse gas (GHG) emissions, including agriculture and land use change, measured in carbon dioxide-equivalents over a 100-year timescale. [ 2 ] This is a list of sovereign states and territories by per capita greenhouse gas emissions due to certain forms of human activity, based on the EDGAR database created by European ...
This is a list of sovereign states and territories by per capita carbon dioxide emissions [n 1] due to certain forms of human activity, based on the EDGAR database created by European Commission. The following table lists the annual per capita CO 2 emissions estimates (in kilotons of CO 2 per year) for the year 2023, as well as the change from ...

The Integrated Carbon Observation System (ICOS) is a research infrastructure to quantify the greenhouse gas balance of Europe and adjacent regions. In November 2015 it received the international legal status of ERIC ( European Research Infrastructure Consortium ) by decision of the European Commission. [ 1 ]
