In today’s world, where sustainability is becoming a priority across all industries, the adoption of green shipping practices in logistics is not just a trend — it’s become a necessity. In response to the increasing pressure to reduce its carbon footprint, the logistics industry has focused on adopting more sustainable practices, including the use of eco-friendly technologies and strategies to minimise the environmental impact of transportation.
This article delves into new green technologies that are transforming the shipping industry, examines how they are being applied, and discusses their significant potential to reduce environmental damage.
The importance of green shipping
The logistics and transportation sector plays a pivotal role in the global economy, but it is also a major contributor to carbon emissions, primarily due to its heavy reliance on fossil fuels. According to the International Organization for Standardization (ISO), this sector is responsible for just over a third of global carbon dioxide (CO2) emissions, making it the largest-emitting sector in many developed countries. This significant environmental footprint underscores the urgent need for more sustainable practices within the industry to mitigate its impact on the planet.
As the world strives to reach the Paris Agreement’s target of limiting global warming to well below 2°C, the pressure on the transport sector to reduce emissions is intensifying. To align with these targets, the industry must cut its emissions by approximately 20%, aiming for less than 6 gigatonnes (Gt) of CO2 by 2030. This is a daunting challenge, especially given the projected increase in global trade demand. However, reducing emissions is not just about meeting targets; it is about taking decisive action to combat climate change and protect our planet for future generations.
1. Sustainable aviation fuel: a key player in green shipping
Sustainable aviation fuel (SAF) is increasingly recognised as a crucial element in advancing green shipping, especially in air freight. Unlike conventional jet fuel, SAF is produced from renewable and sustainable feedstocks, such as waste oils, agricultural residues, and non-food crops.
This alternative fuel source is designed to work seamlessly with existing aircraft engines and infrastructure, providing a practical and immediate way to reduce the aviation industry's reliance on fossil fuels. The most compelling benefit of sustainable aviation fuel is its potential to cut lifecycle carbon emissions by up to 80%, making it a substantially cleaner option for air transport and a critical step toward achieving global sustainability targets.
DHL Express is at the forefront of adopting SAF to enhance the sustainability of its logistics operations, particularly through DHL’s GoGreen Plus solution. By integrating SAF into our fuel mix, we’ve made significant strides in reducing its carbon footprint, specifically targeting Scope 3 emissions, which encompass all indirect emissions that occur across a company’s value chain. A notable example of this commitment is DHL's collaboration with SCREEN Semiconductor Solutions. By utilising SAF for their air shipments, this partnership has achieved considerable reductions in carbon emissions, showcasing the tangible benefits of adopting green logistics practices.
2. Electric and hybrid vehicles
Electric and hybrid vehicles represent another significant advancement in green logistics, especially for last-mile delivery. These vehicles, which rely on electric batteries and sometimes a combination of electric and internal combustion engines, significantly reduce the reliance on fossil fuels and consequently lower greenhouse gas emissions.
One of the most notable advantages of electric vehicles is their zero tailpipe emissions, which virtually eliminates the release of harmful pollutants into the atmosphere. This dramatic reduction in emissions contributes directly to improving urban air quality, making cities healthier places to live and work while also helping combat the broader challenge of climate change. In addition to their environmental impact, electric and hybrid vehicles operate much more quietly than traditional vehicles, which significantly reduces noise pollution — a benefit particularly valued in densely populated urban areas.
Despite these benefits, transitioning to electric and hybrid vehicles is not without its challenges. Logistics companies face hurdles such as the need for extensive charging infrastructure and the relatively high initial investment required to purchase these vehicles. However, the long-term benefits are compelling: lower operating costs due to cheaper electricity compared to fuel, and reduced maintenance expenses. These cost savings, combined with the environmental benefits, make electric and hybrid vans and trucks an increasingly attractive option for logistics companies committed to improving their sustainability profile.
3. IoT in green shipping
Digitalisation, propelled by the Internet of Things (IoT), is transforming green shipping practices by making logistics operations more efficient and environmentally friendly. The applications of IoT in logistics are vast and varied, from smart sensors that continuously monitor vehicle performance and environmental conditions to advanced software systems that utilise real-time data to dynamically adjust delivery routes. For example, by leveraging IoT technology, logistics companies can proactively avoid traffic congestion and other potential delays by rerouting vehicles in real-time. This capability helps reduce idle times and fuel consumption, enhancing both operational efficiency and sustainability.
Additionally, IoT-enabled devices can monitor temperature and humidity levels, ensuring that perishable goods are transported under optimal conditions, further reducing waste and enhancing sustainability. Embracing IoT technologies in supply chain management is a strategic move for logistics companies aiming to enhance their sustainability efforts, optimise resource usage, and provide better service to customers, all while contributing to a greener future.
How businesses can transition to green shipping
Transitioning to green shipping is a strategic endeavour that requires a strong commitment to sustainability and a well-thought-out plan. Businesses should start by thoroughly evaluating their existing logistics operations to pinpoint areas where green shipping technologies can be effectively integrated. Additionally, educating employees on sustainable practices and investing in the necessary infrastructure, such as charging stations for electric fleets, are critical to ensure a smooth transition.
Collaborating with established logistics providers like DHL Express can significantly ease this transition. By partnering with us, businesses can tap into a wealth of expertise and sustainable logistics solutions like GoGreen logistics, designed to enhance sustainability, ensuring a smoother journey toward sustainable operations.
As the logistics sector continues to evolve, embracing these green innovations will be essential for businesses aiming to stay ahead in a rapidly transforming market. By leading with sustainable practices, companies not only reduce their environmental footprint but also strengthen their competitive position, contributing meaningfully to global efforts to mitigate climate change.
