The term “net zero” has gained significant momentum in discussions about climate change, sustainability, and environmental policy especially in recent years. As governments, corporations, and individuals alike focus on addressing the looming climate crisis, understanding what net zero truly means and why it matters is very important.
This blog post will detail the concept of net zero, explore its implications for our planet, and discuss why every individual and organization should prioritize achieving this goal.
What is Net Zero?
“Net Zero” refers to the balance between the greenhouse gases emitted and those removed from the atmosphere. The Initiative aims to perfectly balance the quantity of greenhouse gases emitted to the environment with the quantity absorbed so that in the end, greenhouse gases will not linger in the atmosphere.
As the United Nations puts it: “Net zero means cutting greenhouse gas emissions to as close to zero as possible, with any remaining emissions re-absorbed from the atmosphere, by oceans and forests for instance.” This statement does not only define the “net zero” but also states its objectives pointing to us possible ways we can achieve this objective.
When a country, company, or individual achieves net zero, it means that the total emissions produced are equal to the total emissions removed, effectively resulting in no net increase in atmospheric greenhouse gases.
The Basics of Emissions
Greenhouse gases (GHGs) include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), among others. These gases trap heat in the atmosphere, contributing to global warming and climate change.
Achieving net zero typically requires a multifaceted approach involving both reducing emissions through energy efficiency and renewable energy sources, as well as enhancing the removal of existing Greenhouse gases through natural processes (like forest absorption) or technological innovations (such as carbon capture and storage).
Achieving Net Zero
Net Zero can be achieved in several layers:
- Emission Reductions: The need to reduce emissions drives innovation in clean technologies. Investments in research and development for energy efficiency, carbon capture and storage, and alternative fuels lead to breakthroughs that can significantly curb emissions.
By cutting emissions from key sectors such as energy, transportation, and agriculture, we lower the concentration of greenhouse gases (GHGs) in the atmosphere.
This reduction is essential to combat climate change, as high levels of GHGs like carbon dioxide (CO2) and methane trap heat and lead to global warming.
- Carbon Offsetting: Where emissions cannot be avoided entirely, strategies such as tree planting, investing in renewable energy projects, encouraging sustainable land management, and raising awareness can help offset the impact.
While carbon offsetting is not a substitute for direct emissions reductions, it serves as a valuable tool in the transition to net zero. By funding meaningful projects that mitigate emissions and enhance carbon sequestration, carbon offsets can help us achieve a balanced approach to managing our greenhouse gas emissions.
- Direct Air Capture: These advanced technologies use chemical processes to extract CO2 directly from the air and store it underground or use it in products.
DAC can contribute to negative emissions, which means removing more CO2 from the atmosphere than is emitted. By combining DAC with carbon storage (e.g., carbon capture, utilization, and storage), we can achieve net negative emissions, helping to reverse some of the damage done by climate change.
Surprisingly, Captured CO2 from DAC can be utilized to create valuable products, such as synthetic fuels, plastics, and building materials. This can promote a circular economy while also reducing reliance on fossil fuel extraction, further supporting a transition to a sustainable future.
The Science Behind Net Zero
Understanding the science behind net zero is essential for grasping its urgency. The scientific community emphasizes the critical need to curb greenhouse gas emissions to limit global warming to 1.50C above pre-industrial levels.
This threshold is significant, as exceeding it threatens ecosystems, water supplies, and human health globally. Achieving net zero requires careful measurement of emissions from all relevant sources, including energy use, transportation, agriculture, and waste.
Comprehensive accounting enables organizations and countries to develop strategies to reduce emissions effectively. The science of net zero encapsulates a complex interplay between understanding emissions, the carbon cycle, and developing mitigation strategies to balance our planetary systems.
The Paris Agreement
The Paris Agreement, reached in 2015, set a global framework for climate action. It commits countries to limiting global warming and encourages them to set national contributions, or Nationally Determined Contributions (NDCs), reflecting their commitment to achieving net zero emissions.
According to the Intergovernmental Panel on Climate Change, to meet this target, global GHGs emissions must reduce by roughly 45% from 2010 levels by 2030 and reach net zero around 2050. These drastic reductions are necessary to curtail the worst impacts of climate change.
It was in this meeting the agreement to limit global temperature rise to well below 2°C and aim for 1.5°C above pre-industrial levels.
Carbon Neutrality vs. Net Zero
Carbon neutrality typically refers to balancing carbon dioxide emissions specifically and may involve purchasing carbon credits to offset emissions.
In contrast, net zero encompasses all greenhouse gases and necessitates a more comprehensive approach to decarbonization.
From this, we see that net zero goes beyond concerns for CO2.
The Importance of Achieving Net Zero
The importance of achieving net zero can be categorized into several key areas:
- Addressing Climate Change
The primary reason for pursuing net zero is to combat climate change and its potentially devastating effects, including extreme weather events, rising sea levels, and loss of biodiversity.
A successful transition to a net zero economy can help mitigate these impacts, promoting a more stable climate for future generations.
- Economic Opportunities
Transitioning to a net zero economy presents significant economic opportunities. Investing in renewable energy, energy efficiency, and sustainable technologies can generate millions of jobs, stimulate local economies, and lead to greater energy independence.
According to the International Renewable Energy Agency (IRENA), the renewable energy sector alone employed 11.5 million people worldwide in 2018, a number that continues to grow as nations invest in sustainable energy sources.
- Job Creation in the Renewable Sector
Furthermore, as fossil fuel industries face declines due to global shifts toward sustainability, the transition provides an opportunity for workers to reskill and move into emerging sectors.
