Mitigating Greenhouse Gases Emissions and Effects

 

Greenhouse gases are a major contributor to climate change and the warming of our planet. These gases trap heat in the atmosphere and prevent it from escaping into space.

As a result, the Earth's temperature rises, leading to various environmental issues like rising sea levels, extreme weather events, disruptions in agriculture and ecosystems, and more.

It is crucial that we take action to mitigate greenhouse gas emissions to slow down the effects of climate change and protect our planet for future generations. 

 

What Are Greenhouse Gases

Greenhouse gases are crucial for maintaining the Earth's temperature. However, when their levels exceed normal limits, they can lead to adverse effects such as global warming.

 

Greenhouse Gases Examples

1. Carbon dioxide (CO2) is the most common greenhouse gas emitted by human activities like burning fossil fuels and deforestation. It stays in the earth's atmosphere for a long time, making it a significant contributor to climate change.
    
2. Methane (CH4) is another potent greenhouse gas that traps heat more effectively than carbon dioxide but remains in the atmosphere for a shorter time. It mainly comes from natural processes like wetland decomposition and human activities including livestock farming and waste management.
    
3. Nitrous oxide (N2O) is released from agricultural and industrial activities, as well as from the burning of fossil fuels. Although it constitutes a smaller proportion of greenhouse gas emissions compared to carbon dioxide and methane, it has a significant impact due to its high potency and long lifespan in the atmosphere.
    
4. Fluorinated gases are synthetic greenhouse gases generated from industrial processes. They have a very high global warming potential but occur in much smaller quantities compared to other greenhouse gases.
    
5. Water vapour is the most abundant greenhouse gas in the atmosphere, but its concentration is not directly influenced by human activities. Its role in climate change is complex because while it acts as a strong greenhouse gas, its concentration largely depends on other environmental factors.

 

Effects of Greenhouse Gases Emitted

Greenhouse gas emissions lead to several critical environmental impacts:

• Global Warming: The buildup of these gases traps heat, causing climate change. This results in rising sea levels, altered weather patterns, and more frequent extreme weather events like hurricanes and heat waves.
• Air Quality: Emissions interact with sunlight and atmospheric chemicals to create smog and ground-level ozone. This leads to respiratory problems, such as asthma and lung diseases, particularly in high-pollution urban areas.
• Ocean Acidification: As carbon dioxide dissolves into seawater, it lowers pH levels. This makes it difficult for marine life like corals and shellfish to build skeletons and shells, threatening the ecosystems that rely on them.

What Causes Greenhouse Gases

While natural processes play a role, the current crisis is driven by "anthropogenic" output—emissions resulting from human activity.

Since the industrial revolution, we have altered the chemical composition of the atmosphere at an unprecedented rate.

The correlation is clear: as industrialisation has expanded, so has the accumulation of heat-trapping gases. Key drivers include:

• Fossil Fuel Combustion: Burning coal, oil, and gas for energy and transport releases massive amounts of CO2.
• Land-Use Changes: Deforestation removes trees that would otherwise absorb CO2. When forests are cleared or burned, that stored carbon is released back into the air.
• Industrial Processes: Manufacturing cement, steel, and chemicals releases significant volumes of various greenhouse gases as by-products.

What Is the Largest Contributor

The Energy Sector is the single largest contributor to global greenhouse gas emissions. This sector includes:

• The generation of electricity and heat
• Fuel used for transportation

Because the modern world relies so heavily on power for buildings, industry, and travel, this specific area dominates the statistical data regarding our atmospheric burden.

Transforming how we produce and consume energy is therefore the most critical step in reducing our impact.
 

How to Reduce Greenhouse Gases Emissions in Malaysia

CO2 reduction and our carbon footprint hold immense importance in our collective effort to tackle climate change and safeguard the health of our planet.

Human activities like burning fossil fuels for energy, transportation, and industry release carbon dioxide, intensifying the greenhouse effect.

The IPCC reports that human activity has caused a 1.5°C rise in Earth's average surface temperature since pre-industrial times. While seemingly small, this has triggered:

• Extreme weather events
• Rising sea levels
• Ecosystem disturbances

These changes pose substantial risks to the environment, economies, and communities. 

Renewable Energy

As a rapidly developing country with a growing economy, Malaysia can focus on increasing its share of renewable energy sources, such as:

• Solar energy
• Hydropower
• Biomass

Investing in these sustainable alternatives to fossil fuels will help reduce Malaysia’s reliance on carbon-intensive energy sources and cut greenhouse gas emissions.

Sustainable Industrial Practices

Adopting sustainable industrial methods can also lower greenhouse gas emissions. Key strategies include:

• Mono packaging
• Efficient water waste treatment

These efforts can help minimise the environmental impact of industrial activities.
 

Policies and Incentives

For these measures to succeed, strong policies, regulations, and incentives are essential to drive change across industries and communities.

Effective government initiatives could include:

• Promoting renewable energy adoption
• Encouraging sustainable land use practices
• Incentivising eco-friendly technologies

With these actions, significant reductions in greenhouse gas emissions can be achieved.

Ajinomoto Malaysia Is Mitigating Climate Change

As a responsible corporate citizen and supporter of ESG, the Ajinomoto Group set a group vision to achieve a 50% reduction of CO2 emissions by FY2025.

This goal aims to promote environmental sustainability by responding to climate change and ensuring the sustainability of food resources and biodiversity conservation.

As part of the group, Ajinomoto Malaysia has implemented several initiatives to reduce CO2 emissions and our carbon footprint:

• Installing solar panels: We harness the sun's abundant power to generate sustainable energy. These panels supply 4.2MW, providing 25% of the electricity used in the entire factory.
• Switching heat sources: We have transitioned our heat source from fuel oil to natural gas.

These initiatives lessen our reliance on fossil fuels and substantially reduce our carbon footprint to create a greener future.
