Net Zero
Achieving a balance between the greenhouse gases emitted and the amount removed from the atmosphere, resulting in no net impact on the climate.
Climate ScienceNet zero means cutting greenhouse gas emissions as close to zero as possible, with any remaining emissions re-absorbed from the atmosphere by oceans, forests, or carbon capture technologies.
Net Zero vs. Carbon Neutral
- Carbon neutral: Offsetting emissions by purchasing carbon credits - the total emissions may not decrease.
- Net zero: Requires actual deep reductions in emissions (typically 90%+), with offsets used only for residual emissions that cannot be eliminated.
The Global Net Zero Target
The Paris Agreement aims to limit global warming to 1.5°C. To achieve this, the world needs to reach net zero CO2 emissions by approximately 2050. Over 70 countries and thousands of companies have pledged net zero targets.
Career Relevance
Net zero commitments are driving massive investment in renewable energy, energy efficiency, carbon capture, and sustainable infrastructure - creating millions of green jobs worldwide.
