Consider the following statements. The Global Warming Potential (GWP) ...
Statement 3 is incorrect.
Emissions from livestock mainly include carbon dioxide (from urea), nitrous oxide (from livestock dung and urine), and methane (from belching) among others. They contribute towards the greenhouse effect as due to these gases, heat gets trapped around the surface of the earth and causes global warming.
According to the Intergovernmental Panel on Climate Change (IPCC), the Global Warming Potential (GWP) of gases is a metric that helps measure “the radiative effect (determined by the ability to absorb energy) of each unit of gas” over a specific period of time such as 100 years, “as expressed relative to the radiative effect of carbon dioxide.”
Through GWP, we know gases such as nitrous oxide and methane produce more heat around the earth’s surface than carbon dioxide or CO2, which is taken as a reference. It absorbs more energy than CO2 but stays in the atmosphere for a shorter duration. Over a 20-year-period, it has 80 times more GWP than that carbon dioxide, according to the UNEP website.

Consider the following statements. The Global Warming Potential (GWP) ...
Statement 1: The Global Warming Potential (GWP) of gases is a metric that helps measure the radiative effect of each unit of gas over a specific period of time, that is expressed relative to the radiative effect of carbon dioxide.
This statement is correct. The Global Warming Potential (GWP) is a measure used to compare the radiative forcing of different greenhouse gases. It measures how much heat a particular greenhouse gas traps in the atmosphere relative to carbon dioxide over a specific time period, usually 100 years. Carbon dioxide is used as a reference gas with a GWP of 1, and other greenhouse gases are assigned GWPs based on their ability to trap heat compared to carbon dioxide.
Statement 2: Emissions from livestock mainly include carbon dioxide, nitrous oxide, and methane.
This statement is incorrect. While livestock do contribute to greenhouse gas emissions, the main greenhouse gas emitted from livestock is methane. Methane is produced during the digestive process of ruminant animals, such as cows, sheep, and goats. Methane is a potent greenhouse gas with a much higher Global Warming Potential than carbon dioxide. Carbon dioxide emissions from livestock primarily come from land-use changes, such as deforestation for pasture or feed production.
Statement 3: Gases such as nitrous oxide and methane absorb less energy than carbon dioxide but stay in the atmosphere for a longer duration.
This statement is correct. Nitrous oxide and methane have higher Global Warming Potentials than carbon dioxide, meaning they have a greater ability to trap heat in the atmosphere. However, they do not stay in the atmosphere as long as carbon dioxide. Nitrous oxide has a lifetime of about 114 years, while methane has a lifetime of about 12 years. Carbon dioxide, on the other hand, can persist in the atmosphere for hundreds to thousands of years. Despite their shorter lifetimes, the higher Global Warming Potentials of nitrous oxide and methane make them significant contributors to climate change.
In conclusion, two out of the three statements are correct. The Global Warming Potential (GWP) measures the radiative effect of gases relative to carbon dioxide, and gases like nitrous oxide and methane have higher GWPs than carbon dioxide but stay in the atmosphere for a shorter duration. However, emissions from livestock mainly consist of methane, not carbon dioxide.
