  2. Greenhouse gas emissions - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions

    Greenhouse gas emissions. Annual carbon dioxide emissions per person (height of vertical bars) and per country (area of vertical bars) of the fifteen highest-emitting countries (1990-2018) [ 1 ] Greenhouse gas (GHG) emissions from human activities intensify the greenhouse effect. This contributes to climate change.

  3. Carbon emission trading - Wikipedia

    en.wikipedia.org/wiki/Carbon_emission_trading

    Carbon emission trading. Carbon emission trading (also called carbon market, emission trading scheme (ETS) or cap and trade) is a type of emissions trading scheme designed for carbon dioxide (CO 2) and other greenhouse gases (GHGs). A form of carbon pricing, its purpose is to limit climate change by creating a market with limited allowances for ...

  4. Carbon footprint - Wikipedia

    en.wikipedia.org/wiki/Carbon_footprint

    The carbon footprint explained Comparison of the carbon footprint of protein-rich foods [1]. A formal definition of carbon footprint is as follows: "A measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system ...

  5. Net zero emissions - Wikipedia

    en.wikipedia.org/wiki/Net_zero_emissions

    The idea of net zero came out of research in the late 2000s into how the atmosphere, oceans and carbon cycle were reacting to CO 2 emissions. This research found that global warming will only stop if CO 2 emissions are reduced to net zero. [18] Net zero was basic to the goals of the Paris Agreement.

  6. Carbon price - Wikipedia

    en.wikipedia.org/wiki/Carbon_price

    Carbon pricing (or CO2 pricing) is a method for governments to mitigate climate change, in which a monetary cost is applied to greenhouse gas emissions. This is done to encourage polluters to reduce fossil fuel combustion, the main driver of climate change. A carbon price usually takes the form of a carbon tax, or an emissions trading scheme ...

  7. Carbon capture and storage - Wikipedia

    en.wikipedia.org/wiki/Carbon_capture_and_storage

    Carbon capture and storage (CCS) is a process in which a relatively pure stream of carbon dioxide (CO 2) from industrial sources is separated, treated and transported to a long-term storage location. [ 1 ]: 2221 In CCS, the CO 2 is captured from a large point source, such as a natural gas processing plant or coal power plant, and typically is ...

  8. Emissions trading - Wikipedia

    en.wikipedia.org/wiki/Emissions_trading

    Emissions fees or environmental tax is a surcharge on the pollution created while producing goods and services. [52] For example, a carbon tax is a tax on the carbon content of fossil fuels that aims to discourage their use and thereby reduce carbon dioxide emissions. [2] The two approaches are overlapping sets of policy designs.

  9. Carbon dioxide in Earth's atmosphere - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_in_Earth's...

    In Earth's atmosphere, carbon dioxide is a trace gas that plays an integral part in the greenhouse effect, carbon cycle, photosynthesis and oceanic carbon cycle. It is one of three main greenhouse gases in the atmosphere of Earth. Water vapor is the primary greenhouse gas, as of 2010, contributing 50% of the greenhouse effect, followed by ...
