Nondispersive infrared (NDIR) spectroscopy is a widely used method for measuring greenhouse gas concentrations. It involves sucking the gases into the atmosphere, which helps in understanding the Earth System. The Cape Grim measurement station in Cape Grim, South Africa, is one of the main sites for this process. Greenhouse gas monitoring involves directly measuring emissions and levels of these gases. There are various methods of measuring carbon dioxide concentrations, with the Global Warming Potential (GWP) being a well-defined metric based on radiative forcing.
The 2022 Emissions Gap Report, due to be released in October, focuses on how fast countries can reduce their greenhouse emissions. GHG emissions are typically measured in carbon dioxide equivalent (CO2) equivalent, which is expressed in kilograms of GHG per unit of activity. The unit of measure used in a GHG inventory is tonnes of carbon dioxide equivalent (tCO2e).
The NIST Greenhouse Gas (GHG) Measurements Program develops advanced tools and standards for accurately measuring GHG emissions. Each gas has a distinctive absorption fingerprint that can be used to identify and measure that gas. For example, the unit Tg is most relevant to view total national GHG emissions, while selecting the unit Mg might be more relevant to view emissions of a specific gas.
Greenhouse gases, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), are the gases in the atmosphere that raise the surface temperature of planets like Earth. The first two greenhouse gases were measured in the Netherlands since the 1990s.

Earth is a comfortable place for living things. It’s just the right temperatures for plants and animals – including humans – to thrive.
What unit is greenhouse gas measured in?
GHG emissions are measured in carbon dioxide (CO2) equivalent and are converted into CO2 equivalent by multiplying the gas’s Global Warming Potential (GWP). The GWP considers that many gases are more effective at warming Earth than CO2, per unit mass. Carbon dioxide (CO2) is emitted through burning fossil fuels, solid waste, trees, and chemical reactions, while methane is emitted during coal, natural gas, and oil production, livestock, agricultural practices, land use, and organic waste decay.
Nitrous oxide (N2O) is emitted during agricultural, land use, and industrial activities, combustion of fossil fuels and solid waste, and wastewater treatment. Fluorinated gases, such as hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride, are synthetic, powerful greenhouse gases emitted from various household, commercial, and industrial applications. They are sometimes used as substitutes for stratospheric ozone-depleting substances.
Fluorinated gases are typically emitted in smaller quantities than other greenhouse gases but are potent greenhouse gases with GWPs ranging from thousands to tens of thousands, making them high-GWP gases.
What is the unit of GHG?
The tool employs the metric ton of carbon dioxide equivalent (MTCO2e) as a unit of measurement, representing the quantity of a greenhouse gas (GHG) with a standardized atmospheric impact based on its global warming potential (GWP).

How are greenhouse gas levels measured?
Greenhouse gases, invisible and odorless, are airborne molecules that trap light from Earth’s surface, warming the planet and increasing the likelihood of extreme weather. They absorb specific colors of light, creating a unique “fingerprint” that can be detected in the atmosphere. Scientists study light passing through air and measure the amount of light missing at colors uniquely absorbed by a specific gas.
The challenge of reducing greenhouse gas concentrations has led to global treaties, billions of dollars in government and corporate spending, and political debates. In 1994, nations committed to stabilizing greenhouse gas concentrations to prevent dangerous human-induced interference with the climate system.
Can greenhouse gases be measured?
Greenhouse gas measurement has advanced significantly since Charles Keeling’s time, with scientists now measuring these gases globally using various methods from ground, air, and space. These measurements will help governments, companies, and others identify greenhouse gas sources and monitor emissions reduction efforts. The ultimate goal is to reduce the amount of greenhouse gases in the atmosphere, a global goal that has been in the making for decades.
What is GHG calculation?
The Tier 1 Calculation Method, which involves calculating GHG emissions based on fuel usage, high heat value, and emission factor, is the most common method. This method is available from the EPA’s GHG Reporting Program (GHGRP) documentation and personal records. It is applicable to a few GHGs, such as CO2, CH 4, and N2O, but only if the GHGRP ruling documentation permits it for your specific operating scenario. The EPA has an online CO2e calculator for conversion, but it is essential to double-check results.
What is the unit of greenhouse?
The term “carbon dioxide equivalent” (CO2e) is used to quantify the global warming impact of various greenhouse gases. It is a unit of measurement that represents the amount of CO2e associated with a given quantity and type of greenhouse gas.
How to quantify greenhouse gas emissions?
The Intergovernmental Panel on Climate Change (IPCC) has highlighted the impact of higher greenhouse gas (GHG) concentrations on the environment. Reports warn of increasing extreme weather events, including heatwaves and heavy rainfall, leading to droughts, wildfires, floods, and infrastructure destruction. These changes also pose risks to economic activity, particularly the agricultural sector, which faces unseasonably warm temperatures and drought conditions, threatening worker safety and crop performance.
What is the metric for greenhouse gases?
The standard metric for quantifying greenhouse gas emissions is ‘carbon dioxide-equivalents’. While carbon dioxide is the most dominant greenhouse gas, other greenhouse gases like methane, nitrous oxide, and trace gases like ‘F-gases’ also contribute significantly to global warming. These gases are produced by burning fossil fuels, industrial production, and land use change. The focus on CO2 in climate change discussions is crucial to understanding the broader issue.
What is 1 kg of CO2 equivalent to?
The quantity of carbon dioxide generated by operating a typical automobile is approximately 3. A distance of 7 km, with an estimated fuel consumption of half a litre of petrol per 100 km, is equivalent to the emission of 1 kg of carbon dioxide, which has a volume of approximately 1600 litres. This volume is comparable to that of a large beach ball with a diameter of slightly over 1 metre.
