Net Zero is a term used to describe the balance between the amount of greenhouse gases emitted into the atmosphere and the amount removed or offset. It is an ambitious goal to achieve a state where the net emissions of greenhouse gases are zero, effectively reducing the impact of human activities on climate change.
Key Points about Net Zero:
- Definition: Net Zero refers to achieving a balance between greenhouse gas emissions and their removal or offset [1]. It is also known as ‘carbon neutrality’ or ‘climate neutrality’.
- Importance: Net Zero is crucial in the fight against climate change because it aims to limit global warming to a safe level. By reducing net emissions to zero, we can mitigate the adverse effects of climate change and protect the planet for future generations.
- Emission Reductions: Net Zero requires significant reductions in greenhouse gas emissions across various sectors, including energy, transportation, industry, buildings, and agriculture [2]. This involves transitioning to renewable energy sources, improving energy efficiency, adopting sustainable practices, and implementing innovative technologies.
- Carbon Offsets: Achieving Net Zero may involve the use of carbon offsets, which are projects or activities that remove or reduce greenhouse gas emissions elsewhere to compensate for emissions produced. However, it is important to ensure the social and environmental integrity of carbon offsets and regulate their use effectively [2].
- Comprehensive Approach: Net Zero requires a comprehensive approach to emission reductions, addressing all sectors and sources of emissions. It involves transitioning to zero-carbon solutions in sectors such as heavy industries, buildings, food and agriculture, aviation, and mining [2].
- Front-Loaded Emission Reductions: To maximize the effectiveness of Net Zero, it is crucial to front-load emission reductions. This means taking immediate and significant action to reduce emissions as much and as fast as possible. Delaying emission reductions can limit the time available to reach net-zero emissions while keeping global warming below 1.5°C [2].
