5.4 SIGNIFICANCE OF GREEN JOBS
Green jobs help to reduce negative environmental impacts. Their benefits
include:
Keeping greenhouse gas emissions under control: Reducing
greenhouse gas emissions is crucial in combating climate change
and ensuring a sustainable future. Greenhouse gases like carbon
dioxide, methane, nitrous oxide, ozone, and chlorofluorocarbons
(CFCs) trap heat in the Earth's atmosphere, leading to global
warming. These emissions result from industrial activities, fossil
fuel combustion, deforestation, vehicle emissions, and agricultural practices. To mitigate their impact,
individuals and industries are transitioning to renewable energy sources such as solar, wind, and
hydroelectric power, adopting energy-efficient technologies, and promoting sustainable transportation
options like electric vehicles and public transit. Additionally, afforestation and reforestation efforts
help absorb carbon dioxide, while innovations in carbon capture and storage (CCS) technology
offer new ways to reduce emissions. By embracing cleaner energy, sustainable agriculture, and
eco-friendly industrial practices, societies can effectively control greenhouse gas emissions and protect
the environment for future generation.
Reducing waste and pollution: Instead of focusing just on how to
recycle or reuse waste, we must seek strategies to reduce the
amount of waste produced. This will assist in waste management.
Managers at manufacturing plants and factories are constantly
looking for new ways to reduce the amount of waste produced at
each stage of the process. Here are a few examples:
• Reusing waste materials: It is an effective way to reduce environmental impact and promote
sustainability. In paper mills, damaged rolls are returned to the production line as raw materials,
minimising waste and resource consumption. Similarly, plastic offcuts and scraps are reintegrated into
new products during the manufacturing process. In the textile industry, fabric scraps and defective
clothing are repurposed into new garments, insulation materials, or upholstery. The construction
industry also embraces reuse by incorporating recycled concrete, bricks, and wood into new building
projects. Additionally, electronic waste is salvaged for valuable components like metals and circuit
boards, which are then used in the production of new electronic devices. These practices not only
reduce waste but also conserve natural resources, lower production costs, and decrease pollution,
making them essential for a circular economy.
• Maintaining quality control: It waste by minimising the number of defective products. Automated
monitoring systems, such as AI-powered inspections, detect production issues early. In the
automobile industry, robotic sensors ensure precision in assembling parts. The food industry uses
sorting machines to remove defective items before packaging. Pharmaceutical companies employ
advanced testing to ensure medicine purity, preventing batch rejections.
• Exchange of waste: This is the process through which a waste product from one process becomes
a raw resource for another. It shows a method of reducing trash disposal via reusing. For example,
fly ash from coal power plants is used in making cement, enhancing construction sustainability. In
the food industry, fruit peels and leftover grains are repurposed into animal feed or biofuels. Textile
scraps from garment factories are recycled into insulation materials or new fabrics. Additionally,
discarded plastic bottles are transformed into polyester fibers for clothing and accessories. This
approach promotes a circular economy, conserving resources and minimizing environmental impact.
