This can be done through mentorship initiatives and collaborations that aim to create healthy and safe workplaces, in line with the UN Sustainable Development Goals.

Reducing air pollution from industrial smokestacks

Implement Pollution Control Technologies

Various technologies can be utilised to remove pollutants from smokestack emissions. These technologies include electrostatic precipitators, fabric filters, venturi scrubbers, cyclones, and settling chambers.

• Electrostatic precipitators use magnetic attraction to capture smaller-sized pollutants. The emission gases are charged and then drawn to specially charged plates, resulting in a 99% clean emission stream.
• Fabric filters, or baghouses, employ porous fabric to remove fine particles from the emission stream. The fabric must be capable of withstanding high temperatures and corrosive chemicals.
• Venturi scrubbers mix water with emission gas to combine pollutant particulates, which then settle out of the gas stream.
• Cyclones mimic natural cyclone motion to force larger pollution particles to a hopper, allowing clean gases to exit from the top.
• Settling chambers slow down the velocity of gaseous emissions, causing larger particles to drop out, though they are often used in conjunction with other technologies as smaller pollutants may remain.

Improve Access to Technology and Expertise

Less Economically Developed Countries (LEDCs) often lack the resources, knowledge, and technology to effectively address industrial air pollution. Mentorship initiatives and collaborations with more economically developed nations can provide valuable opportunities to gain access to technical assistance, skills development, and the integration of occupational health practices.

Regulatory Measures and Policy Implementation

Governments play a crucial role in reducing air pollution by implementing and enforcing policies that promote the use of cleaner technologies and energy-efficient lighting. For example, policies can encourage the use of full cut-off lighting designs to reduce light escaping upwards from commercial and public spaces. Additionally, individuals can be encouraged to use motion sensor lights and bulbs in their homes to reduce unnecessary light pollution.

Urban Planning and Transportation

Urbanisation in LEDCs presents challenges related to pollution, particularly in rapidly growing cities. To mitigate this, urban planning can incorporate measures such as efficient public transportation systems, well-designed road infrastructure, and the promotion of bike travel to reduce traffic congestion and vehicle emissions.

By implementing these strategies and technologies, air pollution from industrial smokestacks can be significantly reduced, leading to improved air quality and positive health and environmental outcomes.

Investing in renewable energy sources

Paragraph 3:

Paragraph 4:

To promote the adoption of renewable energy sources in LEDCs, governments can play a crucial role. They can offer incentives, such as tax breaks and subsidies, to encourage businesses and individuals to invest in renewable energy technologies. Governments can also establish regulations and standards that promote the use of renewable energy and phase out polluting fossil fuels.

Paragraph 5:

International cooperation and partnerships are also essential in supporting LEDCs' transition to renewable energy. Developed countries and international organizations can provide financial and technical assistance to help LEDCs access and implement renewable energy solutions. Sharing knowledge and best practices can also accelerate the deployment of renewable energy projects in LEDCs.

Paragraph 6:

Finally, it is important to address the social and cultural aspects of energy use in LEDCs. Educating communities about the benefits of renewable energy and involving them in the planning and implementation processes can foster a sense of ownership and encourage behavioral changes that support renewable energy adoption.

Reducing light pollution through new lighting technology

Light pollution is a pressing issue that has gained prominence in recent years. It severely disrupts nocturnal ecosystems, affects the migration of birds, breeding patterns of nocturnal animals, and carries risks to human health and safety. The good news is that this issue can be significantly reduced through the adoption of new lighting technology and some engineering and structural design policies.

One effective way to reduce light pollution is by investing in and utilising new lighting technology that incorporates the full cut-off concept. This concept minimises the escape of light upwards from large commercial places, stadiums, theatres, and public spaces. For example, the UK is in the process of replacing about 30% of its road light fittings that have reached the end of their lifespan. This presents an opportunity to implement new technology that reduces light pollution.

Governments can play a crucial role by enforcing policies that encourage the use of energy-efficient lighting and discourage the excessive use of bright lights. Research has shown that visibility can be improved at night without emitting excessive light into the sky. Individuals can contribute by installing motion sensor-activated lights and bulbs in their homes, ensuring that lights are not left on all night.

Another important aspect of reducing light pollution is the direction of the lighting. Good street lighting should have bulbs covered and facing downwards, a concept known as 'cutting off light at the horizontal'. This ensures that light illuminates the ground where it is needed, reducing the amount of wasted light escaping into the sky.

Switching to low wattage bulbs, particularly warm-white lighting, is another straightforward way to reduce light pollution. LED outdoor lighting, while energy-efficient, often emits a blue light that contributes to light pollution. By moving away from bluish-white lighting, cities can reduce light pollution and improve visibility. The Spanish city of Vélez-Málaga, for example, adopted a dimmable warm-white light system, improving illumination while reducing light pollution.

In conclusion, reducing light pollution in LEDCs can be achieved through a combination of new lighting technology, thoughtful engineering and structural design, government policies, and individual actions. By implementing these measures, we can minimise light pollution's negative impact on ecosystems, human health, and energy consumption.
