CHAPTER ONE

1.1 Background to the Study

Maritime transportation has served as a key driver of economic development for various countries, acting as a primary facilitator of trade between nations over the years. To be more precise, sea transportation accounts for a significant 80-90% share of global trade (Bayırhan and Gazioğlu, 2021; Inal and Deniz, 2021; Zincir, 2022b). The substantial utilization of shipping can be attributed to its energy efficiency when compared to road and air
transportation. The maritime logistics chain comprises numerous distinct phases, with ports emerging as substantial links within this transportation network.

Ports inevitably generate anthropogenic emissions due to the ever-increasing volume of cargo handled, the diversification of the activities accommodated (modern ports, for example, can act as industrial hubs with a variety of activities such as energy production, distribution, and storage), and the dependence of land and seaside port activities on fossil fuels. To date, one of the main concerns of the port industry has been air emissions and GHG emissions associated with seaport operations. Port-related GHG emissions are usually reported on the basis of inventories, while the measurements conducted between different ports can vary considerably. For example, the emissions from ships at berth in the port of Rotterdam are estimated at 13.7 Mton CO2, which is almost double the amount emitted by the port of Antwerp (7.4 Mton CO2), which is ranked number one among the 10 most polluting European ports [1]. Although it is generally assumed that larger ports pollute more, there are examples of small ports that generate high pollution levels. For example, the port of Algeciras is listed as more polluting compared to bigger Spanish ports, such as the port of Barcelona and the port of Valencia. It is responsible for 3.3 million Mton CO2, whereas the port of Piraeus follows behind with 2.7 Mton CO2 [1]. Overall, the European ports are estimated to contribute about 210 Mton CO2 per year, which accounts for 4.7% of the total CO2 emissions in Europe.
In recent years, the global maritime industry has experienced a paradigm shift towards sustainability, with increasing recognition of the deep impact it has on both environmental and climatic conditions. As the being the link between land and sea trade, ports play a crucial role in this transformation, serving as vital hubs for commerce while concurrently contributing to energy efficiency, emissions reduction and climate change. The urgency to
mitigate these negative effects has given rise to the concept of “Green Ports,” an innovative

Approach aimed to harmonize economic activities with environmental
stewardship (Köseoğlu and Solmaz, 2019; Satir and Doğan-Sağlamtimur, 2018). The environmental footprint of traditional ports has been a cause for concern, primarily
due to the emission of greenhouse gases, air pollutants, and the ecological disturbance caused by port infrastructure development (Gültepe Mataracı, 2016). The maritime industry, being a major contributor to global carbon emissions, has drawn increased attention from regulatory bodies, environmentalists, and the public alike.

Previous studies have explored the role of ports towards the greening of the sector, providing a solid basis for green port activities, as well as a good overview of different groups and areas of implemented solutions. In terms of decarbonization, much attention has been paid to the ship–port interface, focusing on technical and operational measures, such as provision of onshore power, alternative fuel bunkering, reduction of ship turnaround time, reduction of truck emissions, monitoring and modelling of air emissions, and various incentive schemes that ports apply to ensure ships’ compliance with relevant environmental regulations and policies. Relevant published research also reveals the process of converting ports to a smart, sustainable, and emission-free infrastructure highlighting the importance of information systems into ports’ infrastructures and energy management measures. The term “greening” of port operations, commonly discussed in the literature, lies within the wide range of actions and measures towards port environmental sustainability and resilience trying also to accomplish net-zero pollution over time.

Carbon dioxide (CO2) emissions from human activities are now higher than at any point in our history. In fact, recent data reveals that global CO2 emissions were 182 times higher in 2022 than they were in 1850, around the time the Industrial Revolution was underway.1

For context, the United Kingdom was the world’s largest CO2 emitter in 1850, the first year of available data. Its emissions were nearly six times those of the United States, the second-ranked country at the time. France, Germany and Belgium completed the list of the top five emitters.

As of 2022 — the latest data available — China ranked as the world’s largest CO2 emitter, followed by the United States, India, Russia and Japan. However, among the top 10 CO2 emitters, the United States has the highest emission per person. Per capita emissions in the U.S. are double those of China and 8 times those of India.

Wind Energy into onboard ferry power Wind energy is recognized as a viable substitute as the maritime industry experiences pressure to adopt renewable energy, especially for short to medium routes. The research uses the Weibull distribution to evaluate wind speeds at 10,20,30 and 40 meters using wind speed data from 2020 to 2023. The results show that wind energy harnessing is a viable option, with mean wind speeds of 4.017482,5.06268,5.80696 and 6.40713 m/s respectively. This highlights how ferry operations could become less reliant on single-unit conventional nonrenewable energy particularly fossil fuels by incorporating wind assisted technologies. Ferries must transition towards onboard multiple energy sources to engage in sustainable maritime operations. Wind energy may play a significant role in reducing the environmental impact of ferry operations. The study emphasizes how important it is for the maritime industry to use renewable energy.

1.2 Statement of the problem 

The Clean & Green Technology theme in Smart India Hackathon 2024 is dedicated to fostering innovations that contribute to environmental sustainability and the efficient use of resources. Many problems facing environmental protection and waste management cannot be quantified or compared in their sheer magnitude. With urbanization and population growth, there are many problems around energy, water, natural resources, and other areas. Through SIH-2024, Indian universities can take the lead in solving today’s environmental problems. By participating in Smart India Hackathon, these institutions can help to improve the air we breathe, address waste issues, solve cleaning problems, mitigate water scarcity problems, and more by utilizing technology.

The problem of greenhouse emissions is a global issue that requires technological solutions to reduce the amount of carbon dioxide in the atmosphere at the port of Douala. The emission of high level of carbon dioxide at the Douala seaport cause serious health issues on the people working and living closer to the Douala seaport. Climate change cause by carbon emissions causes damage to infrastructures in Douala such as, sustainable renewable energy. Green house emission rises the global temperatures and altered the ecosystems that threat lots of living organisms in the ecosystem. Mores so air pollution resulting from gas emission contributes to poor quality air, thus causing a serious human health challenges. The lack of financial incentives and subsidies can make it difficult for smaller businesses and individuals to afford the upfront costs of green technologies, slowing down their adoption

Electric vehicles and other green transportation technologies can significantly reduce greenhouse gas emissions. However, the limited availability of charging infrastructure and the high cost of electric vehicles can be a challenge. By addressing these problem areas, it is possible to accelerate the adoption of green technologies and create a more sustainable future. Despite all these problems resulting from greenhouse emission, little has been written making a study on the role of green technologies in reducing carbon emissions at the port of Douala is inevitable.
