The main greenhouse gases are Carbon Dioxide (CO₂), Methane (CH₄), Nitrous Oxide (N₂O), Fluorinated Gases, and Water Vapor (H₂O). These gases trap heat in the atmosphere, causing global warming and climate change.
Energy production causes 73.2% of emissions. This includes heat and electricity (24.2%), transportation (16.2%), industry (24.2%), and agriculture (11.1%). These activities are the biggest contributors to greenhouse gas emissions globally.
CO₂ levels have risen by over 50% since the Industrial Revolution, driving climate change. Methane and nitrous oxide have higher warming potentials despite lower concentrations.
Emissions are measured using ground-based monitoring, satellites, estimation methods, and modelling to track gas concentrations and predict future emissions.
Countries are working to reduce emissions through renewable energy, energy efficiency, and international agreements like the Paris Agreement, but more action is needed.
While progress is being made, the pace must accelerate to prevent severe climate impacts. Global cooperation and individual actions are essential for a sustainable future.
