Sectors that Contribute to Greenhouse Gas Emissions
The main sectors that contribute to greenhouse gas emissions include:
- Energy production: The burning of fossil fuels (such as coal, oil and natural gas) for electricity and heat production is the largest source of greenhouse gas emissions, specifically carbon dioxide (CO2).
- Transportation: The burning of fossil fuels by cars, buses, trucks, ships and airplanes also contributes to greenhouse gas emissions.
- Agriculture: Agriculture and livestock farming are also sources of greenhouse gas emissions, specifically methane (CH4) and nitrous oxide (N2O) emissions from livestock and manure, and CO2 emissions from the use of synthetic fertilizers and deforestation.
- Industry: Industries such as cement, steel, chemicals, and oil refining also contribute to greenhouse gas emissions through the burning of fossil fuels and chemical reactions that take place during production.
- Buildings: Heating and cooling of buildings also contribute to greenhouse gas emissions, by the burning of fossil fuels for heating and the use of electricity for cooling.
- Waste: Landfills and waste treatment facilities also emit methane, a potent greenhouse gas.
What is Net Zero and Why is it Important?
Net zero refers to the balance between the amount of greenhouse gas emissions produced and the amount removed from the atmosphere, resulting in no net increase in atmospheric greenhouse gas concentrations. It means that any greenhouse gas emissions that cannot be reduced, should be balanced by an equivalent amount of carbon removals. This can be achieved through a combination of reducing emissions at source, such as through the use of renewable energy, and through carbon sequestration or removal activities, such as reforestation, afforestation, and soil carbon sequestration. The ultimate goal is to achieve a balance between emissions and removals, thus preventing further increases of greenhouse gases in the atmosphere and contributing to mitigating the effects of climate change.
