Explanation

Hydrogen is not considered a greenhouse gas.

While carbon dioxide (CO2), methane (CH4), and water vapor (H2O) are greenhouse gases, hydrogen (H2) itself does not exhibit significant greenhouse gas properties. It is important to note that although hydrogen is not a greenhouse gas, its interactions with other greenhouse gases and its role in various industrial processes can have implications for climate change and the overall greenhouse gas balance.
