#CarbonCatchers #EcoEducation


The world has never been more digitized, and with many businesses moving online due to the current COVID-19 pandemic, the demand for digital services reaches new heights every day. What many would not suspect, however, is the significant environmental impact of our digital activities.


According to the latest statistics, information and communications technologies (ITC) account for 4 percent of global greenhouse gas emissions - twice as much as the world aviation industry (Jungblu, 2020). A staggering percentage that is predicted to double by 2025, as more than one million people come online for the first time each day (Kemp, 2019).


Where emissions are coming from

Every action that is carried out online comes with a few grams of carbon dioxide being released into the atmosphere. Since the energy used to run the devices and to power the networks mainly comes from fossil fuels, even the smallest online activity - like a search query - can produce anywhere between 0.2 to 7 grams of carbon dioxide emissions (Ho, 2020). If we think about how many people perform digital activities every day, even a few grams of emissions quickly add up to a significant environmental impact.

Among these activities, music and video streaming are one of the main causes of the internet’s high power consumption. Studies show that almost 80 percent of all data flows through the net in the form of moving images (Griffiths, 2020). Online videos alone account for almost 60 percent of global data transfer. The higher the resolution, of course, the more data is sent and received.



More energy-intensive, however, are the data centres and servers needed to power the internet and store the content that we are so easily able to access through our searches. Despite the difficulty in knowing for certain how much energy is required by all data centres worldwide, current estimates have calculated a range from 200 to 500 billion kilowatt-hours per year, an estimated 1 to 3 percent of the world’s electricity. By 2030, the range is estimated to be between 200 billion and 3,000 billion kilowatt-hours (Stolz and Jungblut, 2019).

The energy required by data centres is not only used to send and receive data streams but mostly to prevent the servers from overheating. Once the data is processed additional energy is required for ventilation so that the servers can be cooled down. On average, mechanical cooling is responsible for around 25 percent of the total power consumption of a data centre (Stolz and Jungblut, 2019). On top of the environmental impact of using large amounts of power to cool down the servers, the heat produced by data centres and that is released into the atmosphere, becomes an additional factor contributing to global warming.

Cloud computing is another major contributor to the high energy consumption of the internet. The more data we store on servers instead of locally on our devices, the more energy the servers will need.

But it doesn’t end there. From manufacturing to disposal, the lifecycle of computers has a significant environmental impact. It’s enough to think that an estimated 50 million tons of electronic waste are discarded each year and most of it is sent to landfills (Maier, 2019).

According to a research article by the University of Edinburgh, extending the life of a single computer and monitor from four to six years could avoid the equivalent of 190kg of carbon emissions (Hart, 2016).



The amount of emissions varies depending on website traffic, the amount of data transferred over the wire when a web page is loaded, or the amount of energy used at the data centre, telecoms networks and by the end user's computer or mobile device. The energy source used by data centres is also a key factor as many data centres are shifting towards renewables.

Solutions

The environmental impact of our digital operations, even after breaking them down, can feel intimidating. However, there are a multitude of solutions being explored and implemented every day to make sure that the Planet doesn’t pay the price for an increasingly interconnected world. Some countries, like Sweden for instance, are repurposing the heat waste coming from their data centres by redistributing it to residential and commercial buildings via pipes.

Tech corporations are also finding solutions to reduce the carbon footprint of their operations. Google uses a mixture of renewable energy and carbon offsetting, while Microsoft has promised to become carbon negative by 2030 (Griffiths, 2020).

A recent study published in the Journal of Parallel and Distributed Computing offers an alternative solution to decrease the amount of energy used by cloud computing. The research proposes using multi-cloud computing and storage services in different time zones, instead of a single one, to run applications, services and capabilities. By estimating the amount of solar power that each location will need depending on its time zone, the study suggests that it is possible to reduce the usage of energy produced with fossil fuel and maximize the use of renewable energy at different locations. (Xu and Buyya, 2020)

It’s not only up to governments and corporations, however, users can do their part too. Offsetting the CO2 emissions of your website, for instance, can be an easy and affordable starting point for both individuals and businesses. There are numerous ways to do that depending on your means and needs. The Tree-Nation Offset Website service, for instance, allows you to place a smart label on your website to calculate and offset all of your website's CO2 emissions by automatically planting trees.



Trends

  • Computing is expected to account for up to 8% of global power demand by 2030.
  • There are over 4 billion internet users as of January 2021, an increase of over 7 percent compared to the previous year.

Calculations

  • A typical business user creates 135kg CO2 from sending emails every year, which is the equivalent of driving 200 miles in a family car.
  • Data centres are generally rated for energy efficiency using a metric called Power Usage Efficiency, or PUE. The PUE is determined by dividing the amount of energy entering the data centre by the amount of energy used to run the computers inside it. The typical PUE for a data centre is around 1.67, meaning that for every 1.67 watts going into the data centre, only 1 watt is being used to power the computing systems.

The Carbon Footprint Debate: Experts' and Students' Differing Views

Discussions concerning environmental sustainability as well as global warming now centre on the idea of the carbon footprint. Understanding our impact on the earth requires an understanding of this statistic, which measures the greenhouse gas emissions caused by people, organizations, or products both directly and indirectly. But when it comes to reducing carbon footprints, professionals in the area have different views than students, who are our planet's future stewards. This difference in viewpoints provides important insights into the obstacles and possibilities facing the fight against climate change.


The carbon footprint issue is usually approached by experts, such environmental scientists and policy officials, with a combination of urgency and pragmatism. They stress the significance of all-encompassing approaches that incorporate modifications to laws and regulations, advances in technology, and significant societal upheavals. In order to encourage the use of renewable energy, energy efficiency, and sustainable practices in all industries, experts frequently support strict laws and incentives. They emphasize the need for strong international collaboration and climate legislation, emphasizing that while individual acts are vital, they cannot accomplish the significant reductions required to prevent catastrophic climate change.

Students, on the other hand, frequently display a more idealistic and proactive attitude toward reducing their carbon footprint. Due in part to the increased focus on environmental issues and the obvious repercussions of climate change in school, a large number of students are well aware of the climate catastrophe. This group typically views changing one's lifestyle and taking personal responsibility as important ways to combat global warming. Students are eager to make quick, noticeable changes in their daily lives, such as cutting back on meat intake, cutting waste, and choosing sustainable modes of transportation. Younger generations are encouraged to become environmentally conscious through the influence of their peers and social media.

Experts can be sceptical of students' enthusiasm even when it comes to the efficacy of particular activities. Experts contend that although individual decisions are admirable, they cannot have a substantial effect unless they are a component of a larger systemic shift. This skepticism serves to emphasize the scope of the problem and the need for all-encompassing remedies rather than to dissuade individuals from taking personal responsibility.

To close the gap between various viewpoints, a multimodal strategy is needed. In addition to providing students with the knowledge and skills they need to take personal action, educational efforts should help them get a deeper comprehension of the systemic changes that are required. Scholars ought to acknowledge and bolster students' zeal, including their community-based initiatives into more extensive policy structures. Students and experts working together on projects and having conversations can promote knowledge and awareness

In summary, even while professionals and students may approach tackling carbon footprints differently, their objectives are similar: to lessen the effects of climate change and guarantee a sustainable future. In the global endeavor to reduce carbon emissions, recognizing and utilizing the assets of both perspectives can result in more inclusive and effective methods.

2: Carbon Emissions Reduction: A Critical Need for Sustainable Development

The concerning increase in carbon emissions over the past few decades has emerged as one of the planet's most urgent problems. The main causes of climate change are carbon emissions, which are mostly produced by industrial operations, deforestation, and the combustion of fossil fuels. The overwhelming opinion among scientists is that our environment, economies, and society will suffer ever-more-severe and permanent consequences if we do not move decisively to reduce these emissions. Not only is lowering carbon emissions good for the environment, but it's also essential for human welfare and sustainable development.



First of all, the effects of unregulated carbon emissions on the ecosystem are already felt. Hurricanes, droughts, and wildfires are becoming more common and severe as a result of rising global temperatures. Sea level rise is a result of melting glaciers and polar ice caps, endangering ecosystems and coastal towns. Increased CO2 absorption is causing the oceans to become more acidic, which is killing marine life and upsetting the fishing industry. The alterations in the ecosystem highlight the pressing necessity of cutting carbon emissions in order to prevent additional harm.

In addition, there are significant economic ramifications of climate change. Climate change-related natural disasters cost billions of dollars in damages every year, harming livelihoods, agriculture, and infrastructure. For example, the increased frequency of extreme weather events can cause crop destruction, which would result in a shortage of food and higher costs. Furthermore, the health effects of pollution, including illnesses linked to the heat and respiratory disorders, put a heavy strain on healthcare systems. We can lower the costs associated with climate-related harms while promoting economic growth through green jobs and innovation by investing in low-carbon technologies and sustainable practices.

Socially, the most vulnerable groups bear a disproportionate amount of the consequences of carbon emissions. The least carbon-intensive nations and low-income areas are frequently the most severely impacted by climate change. This makes already-existing disparities worse and makes it more difficult to accomplish global development goals. Therefore, addressing carbon emissions is an issue of climate justice, guaranteeing that everyone has the chance to live in a stable and healthy environment.

Furthermore, it is both economically and technologically possible to shift to a low-carbon economy. The cost-effectiveness of renewable energy sources, like hydroelectric, wind, and solar power, is rising relative to fossil fuels. Developments in electric cars, sustainable agriculture, and energy efficiency offer workable solutions for cutting emissions dramatically. Through investments, regulations, and lifestyle modifications that put sustainability first, businesses, individuals, and governments can all contribute to this transition.

Green Engineering's Crucial Role in Creating Our Future
Green engineering has the potential to significantly impact how our planet develops in the future. Considering the two crises that we face—climate change and environmental degradation—integrating sustainable methods into engineering becomes not only advantageous but also imperative. In order to solve the urgent environmental issues of our day, green engineering principles—which place an emphasis on the use of goods and processes that minimize resource use, decrease pollution, and promote sustainability—are essential.

The ability of green engineering to slow down climate change is one of its main benefits. Economic gains have frequently taken precedence over environmental concerns in traditional engineering procedures, which has resulted in considerable carbon emissions and ecological disturbance. Green engineering, on the other hand, aims to lower the carbon footprint of processes and products through creative design, integration of renewable energy sources, and energy efficiency. The creation of solar- or wind-powered energy-efficient buildings, for instance, demonstrates how green engineering can result in significant drops in greenhouse gas emissions.

Green engineering also promotes the preservation of natural resources, which are getting harder to come by. Green engineering can considerably lessen the depletion of natural resources by encouraging the use of recycled materials, designing for product longevity, and streamlining production procedures to produce waste as little as possible. This guarantees that resources will be available for use by future generations in addition to aiding in the preservation of ecosystems. One example of how green engineering is progressive is the idea of a circular economy, in which goods are made to be recycled, repaired, and reused.


Apart from its positive impact on the environment, green engineering presents significant economic and social benefits as well. Sustainable goods and services are in greater demand as both businesses and customers grow more environmentally conscientious. This change is spurring innovation and opening up new markets for environmentally friendly technologies. In the long run, green engineering techniques can also result in cost savings. Sustainable urban planning may cut public spending on infrastructure and health care, while energy-efficient designs and waste reduction strategies can minimize operating expenses for enterprises.

Socially, green engineering can improve living conditions by encouraging healthier living. Improving air quality and general well-being in urban areas is facilitated by the removal of pollutants and the development of green spaces. Furthermore, by guaranteeing that the advantages of sustainable development are available to all facets of society, especially underprivileged areas that are frequently disproportionately impacted by environmental challenges, green engineering can play a critical role in promoting social fairness.

In summary, it is impossible to overestimate the importance of green engineering in the future. It is a pillar of sustainable development, tackling environmental issues and providing social and economic advantages. Green engineering principles will be essential in building a resilient, sustainable, and just world in the future. It is essential that we adopt these values now in order to ensure a wealthy and healthy planet for future generations.
