Air pollution caused by technology

Technology has had a significant impact on the environment, and air pollution is a critical issue that has been exacerbated by technological advancements. The production and use of technology have led to a rise in air pollution, causing harm to both human health and the planet.

The burning of fossil fuels, the operation of factories, power stations, mass agriculture, and vehicles are significant contributors to air pollution. These technologies, which emerged following the Industrial Revolution, have introduced harmful gases such as carbon dioxide, carbon monoxide, sulfur dioxide, nitric oxide, and methane into the Earth's atmosphere. The consequences of this pollution include negative health impacts and global warming, as the increased greenhouse gases trap thermal energy, causing a rise in global temperatures.

The manufacturing of technology also generates a large amount of waste, and electronic waste, or e-waste, is the most rapidly growing type of waste. In addition, the production of electronic devices and the development of powerful infrastructures require a large number of natural resources, contributing to environmental issues such as deforestation, soil degradation, and water pollution.

Furthermore, the energy needed to power servers, data centers, and devices contributes to greenhouse gas emissions, as seen in cryptocurrency mining. These emissions further contribute to global warming and climate change. The lack of proper management of e-waste and the manufacture of electronic components often involve intensive industrial processes that emit pollutants into the air.

However, it is important to recognize that technology also plays a crucial role in mitigating air pollution. Technological innovations such as cleaner manufacturing processes, smokestack scrubbers, catalytic converters, and low-VOC paints have been developed to reduce pollution. Additionally, the concept of "Environmental Technology" or "green technology" aims to conserve, monitor, and reduce the negative impact of technology on the environment. Renewable energy sources, such as solar panels and wind turbines, are now being utilized to capture naturally occurring energy and convert it into electricity, reducing our dependence on fossil fuels.

Greenhouse gas emissions

Technology has had a significant impact on greenhouse gas emissions, and the continued development and adoption of new technologies will be crucial in reducing emissions in the future.

The production and use of technology, as well as the energy required to power it, have contributed to the emission of greenhouse gases. Cryptocurrency mining, for example, has been identified as a contributor to these emissions. However, technology also offers innovative solutions to reduce greenhouse gases and combat global warming.

One notable example is the development of renewable energy sources, such as solar radiation, wind, biomass, geothermal, and hydroelectric power. These sources do not produce hazardous waste and contribute to reducing greenhouse gas emissions while decreasing dependence on fossil fuels. The use of new technologies that favour renewable energy sources over fossil fuels is essential for sustainable mobility in cities.

Additionally, advancements in waste management, particularly recycling, play a crucial role in reducing greenhouse gas emissions. Recycling reduces the need for extracting new raw materials, manufacturing new products, and consuming energy. Technology enables the implementation of automated sorting and waste separation systems, improving the efficiency of the recycling process.

In the concrete industry, CarbonCure technology introduces recycled CO₂ into fresh concrete, reducing its carbon footprint without compromising performance. The injected CO₂ undergoes mineralization and becomes permanently embedded in the concrete, resulting in economic and climate benefits for producers.

Another innovative solution is the use of direct air capture technology, such as that provided by Climeworks. This technology uses a filter to capture atmospheric carbon, drawing in air and binding CO₂, which can then be utilized in industrial applications.

Furthermore, the efficient management of natural resources is facilitated by technologies like the Internet of Things (IoT) and smart sensors. These technologies enable the monitoring and control of resource consumption, such as water and energy, optimizing their use and reducing waste.

The aviation industry is also making strides towards reducing greenhouse gas emissions. For instance, GE Aviation has successfully tested the Passport engine, a long-range business aviation turbofan, with a 3% lower fuel consumption rate compared to other engines in its class.
