Net zero emissions and carbon neutrality have emerged as essential concepts in the global fight against climate change. In a world increasingly plagued by environmental degradation and the looming threat of catastrophic climate events, achieving net zero emissions and carbon neutrality has become a paramount goal for governments, businesses, and individuals alike. Simply put, net zero emissions refers to the balance between the amount of greenhouse gases produced and the amount removed from the atmosphere. Similarly, carbon neutrality entails offsetting carbon dioxide emissions through measures like carbon capture and storage, reforestation, or renewable energy adoption. These concepts signify a transformative shift towards sustainable practices and renewable energy sources, aiming to mitigate the adverse impacts of climate change and safeguard the planet for future generations. As the urgency of addressing climate change intensifies, the pursuit of net zero emissions and carbon neutrality stands as a critical milestone in the collective effort to combat environmental degradation and secure a sustainable future.
- During the 2015 UN Climate Change Conference, an agreement known as The Paris Agreement was established, aiming to transition towards carbon neutrality by the latter half of the 21st Century as a means to alleviate the impacts of climate change.
- Climate change is predominantly driven by the emission of carbon dioxide (CO2), a major contributor to the issue.
- Since the onset of the Industrial Revolution, human activities have increasingly harnessed carbon stored in fossil fuels such as coal, oil, and natural gas.
- The combustion of these fuels releases CO2 into the atmosphere. In May 2019, atmospheric CO2 concentration reached a record level of 415 parts per million (ppm).
- CO2, along with other greenhouse gases (GHG), traps solar radiation, leading to the warming of the Earth’s surface.
- The consequences of global warming in the forthcoming decades could be disastrous, including more frequent and severe droughts, extreme storms and heatwaves, rising sea levels, glacier melting, loss of biodiversity, and substantial disruptions in people’s lives, potentially resulting in climate-induced migration.
CARBON NEUTRALITY
- As per the Intergovernmental Panel on Climate Change (IPCC) definition, carbon neutrality, or net zero CO2 emissions, specifically pertains to achieving a balance between the carbon dioxide (CO2) emitted into the atmosphere and the CO2 removed from it.
- In practical business contexts, organizations frequently use the term “carbon neutrality” more broadly, encompassing all greenhouse gas (GHG) emissions when articulating their ambitious emission reduction targets.
- According to the European Parliament, carbon neutrality is attained when the quantity of CO2 released into the atmosphere equals the amount removed by various methods, resulting in a net balance of zero, commonly referred to as a zero carbon footprint.
- The term “carbon footprint” is defined as the total GHG emissions attributed to an individual, organization, service, or product.
- Various methods can be employed to achieve this balance.
- One environmentally sound approach is to avoid emitting more CO2 than can naturally be absorbed by the world’s forests and plants, which serve as carbon sinks through photosynthesis.
- In this process, they absorb CO2 from the air and convert it into oxygen, aiding in emission reduction.
- In a statement made in 2020, UN Secretary-General António Guterres outlined key factors essential for achieving climate neutrality, including building a global coalition supporting carbon neutrality by 2050, aligning global financial efforts with the Paris Agreement and the Sustainable Development Goals (SDGs), and making substantial progress in adapting to and building resilience against climate change.
DIFFERENCE BETWEEN CARBON NEUTRALITY AND NET ZERO EMISSION
- While in common usage, the terms carbon neutrality, net zero, and climate neutrality are often used interchangeably, the Intergovernmental Panel on Climate Change (IPCC) provides precise definitions for each.
- Net-zero emissions encompass all greenhouse gas (GHG) emissions, indicating a balance between emitted GHGs and those removed within a specified timeframe.
- In contrast, climate neutrality goes beyond net-zero by considering all human impacts that influence the climate.
- Carbon neutrality, technically focusing solely on carbon, is differentiated from “net zero” and “climate neutrality.”
- However, in practical terms, sustainability experts commonly use the term “carbon neutrality” to encompass all GHGs, converting non-carbon GHGs into carbon equivalencies when making assertions based on calculations.
- Going beyond carbon neutrality, the term “carbon negative” implies that an activity not only achieves neutrality but also eliminates more CO2 than it emits.
- An example is Microsoft’s commitment to becoming carbon negative by 2030.
- Conversely, “carbon positive” indicates that an activity releases more carbon into the atmosphere than it removes or compensates for, resulting in a net negative impact on the planet.
METHODS TO ACHIEVE CARBON NEUTRALITY
The Intergovernmental Panel on Climate Change (IPCC) experts assert that achieving carbon neutrality by 2050 and limiting global warming to 1.5°C is possible but requires unprecedented social and political changes. The UN, in recent communications, has outlined short-term directions:
- Implement Carbon Pricing:
- Set a price for carbon emissions that facilitates investment in removal technologies and the development of low-emission alternatives like renewable energy.
- Halt New Coal-Powered Stations:
- Cease the construction of new coal-powered power stations, a significant source of emissions contributing to climate change.
- Shift Carbon Tax Burden:
- Transfer the burden of carbon taxation from taxpayers to the entities responsible for emissions, encouraging industries to adopt cleaner practices.
- Transparent Economic Risks:
- Mandate the disclosure of economic risks associated with climate change, fostering transparency and informed decision-making.
- Integrate Carbon Neutrality Goals:
- Incorporate the objective of carbon neutrality into the financial and fiscal decisions of nations, aligning economic strategies with climate goals.
ADVANTAGES OF REACHING CARBON NEUTRALITY
Reaching carbon neutrality goes beyond averting the most severe consequences of climate change; it also delivers a range of benefits to communities and society at large. These advantages include:
- Reduced Environmental Pollution and Improved Health:
- Carbon neutrality measures contribute to lower levels of environmental pollution, leading to improved air and water quality. This, in turn, has positive effects on public health, reducing respiratory issues and other health-related concerns.
- Stimulus for Sustainable Economic Growth and Green Jobs:
- The pursuit of carbon neutrality fosters sustainable economic growth by promoting investments in renewable energy, energy efficiency, and other green technologies. This, in turn, creates employment opportunities in the expanding green job sector.
- Enhanced Food Security:
- Mitigating the impact of climate change through carbon neutrality measures helps secure food sources. By addressing factors such as extreme weather events and changing agricultural conditions, carbon neutrality contributes to enhanced food security.
- Halting Biodiversity Loss and Improving Ocean Conditions:
- Carbon neutrality efforts play a crucial role in stopping the loss of biodiversity. By addressing climate-related stressors, these measures contribute to the preservation of ecosystems and the well-being of various species. Additionally, they aid in improving the overall condition of the oceans, which are particularly vulnerable to climate change impacts.
FAQs- NET ZERO EMISSIONS
