The term
1. Net Zero and Global Warming:
Net zero entails offsetting emissions from various sources by natural sinks or technological methods. It mirrors a delicate balance, akin to offsetting a heating rod's effect with ice in a bucket of water. Our current emissions far surpass the Earth's capacity to offset them, originating from fossil fuel use, industrial activities, agriculture, and land use changes.
2. Net Zero Categories:
Net zero can refer to either CO2 emissions or greenhouse gas (GHG) emissions. Achieving net zero CO2 emissions by 2055 is crucial to stabilize global warming at 1.5°C. However, focusing solely on CO2 is insufficient; addressing non-CO2 gases is equally vital. Net zero GHG emissions, expected by 2061-2084, encompass a wider range of emissions, contributing to a decline in global warming.
3. Link to 1.5°C Goal:
Net zero serves as a milestone in limiting global temperature rise to 1.5°C by 2100. It stabilizes cumulative emissions and guides efforts to restrict temperature increases. While overshooting temperatures may occur, the long-term goal remains to mitigate climate change's impacts.
Understanding net zero is fundamental to comprehending global climate action. The rising number of countries, cities, and companies committing to net-zero targets offers hope for a concerted effort towards a sustainable future.
