Deutsch: Umweltauswirkungen / Español: Impacto ambiental / Português: Impacto ambiental / Français: Impact environnemental / Italiano: Impatto ambientale

The term Environmental Impact refers to the effects that human activities, systems, or technologies have on the natural environment. In the context of transport, logistics, and mobility, it encompasses the consequences of moving goods and people across various modes of transportation, including road, rail, air, and maritime. These impacts can be both direct, such as emissions from vehicles, and indirect, such as the extraction of resources for infrastructure development. Understanding and mitigating these effects is critical for sustainable development and the long-term health of ecosystems.

General Description

The Environmental Impact of transport, logistics, and mobility is a multifaceted issue that intersects with climate change, air and water quality, biodiversity, and resource depletion. Transport is one of the largest contributors to global greenhouse gas (GHG) emissions, accounting for approximately 20% of global carbon dioxide (CO₂) emissions, according to the International Energy Agency (IEA). These emissions primarily result from the combustion of fossil fuels in internal combustion engines, which powers most vehicles, ships, and aircraft. Beyond CO₂, transport activities release other pollutants, such as nitrogen oxides (NOₓ), sulfur oxides (SOₓ), particulate matter (PM), and volatile organic compounds (VOCs), all of which have detrimental effects on human health and the environment.

The environmental footprint of transport extends beyond emissions. Infrastructure development, such as the construction of roads, railways, ports, and airports, often leads to habitat fragmentation, soil degradation, and the disruption of natural water flows. For example, the expansion of road networks can divide ecosystems, making it difficult for wildlife to migrate or access resources. Similarly, maritime transport contributes to water pollution through oil spills, ballast water discharge, and the release of antifouling agents, which can harm aquatic life. Air transport, while efficient for long-distance travel, has a disproportionately high impact due to the altitude at which emissions are released, which amplifies their warming effect on the atmosphere.

Logistics, as the backbone of global trade, plays a pivotal role in shaping environmental outcomes. The movement of goods across supply chains involves multiple stages, including production, storage, transportation, and distribution, each of which generates environmental costs. For instance, warehousing requires energy for heating, cooling, and lighting, while packaging materials, such as plastics and cardboard, contribute to waste generation. The rise of e-commerce has further intensified these impacts, as it often leads to increased demand for fast, energy-intensive delivery services, such as same-day or next-day shipping. This trend has resulted in a higher number of delivery vehicles on the road, exacerbating traffic congestion and emissions in urban areas.

Mobility, particularly in urban settings, presents unique environmental challenges. The reliance on private vehicles in many cities has led to sprawling urban landscapes, increased air pollution, and higher energy consumption. Public transportation systems, such as buses, trams, and subways, offer a more sustainable alternative, but their environmental impact depends on factors such as energy sources, vehicle efficiency, and ridership levels. Electric vehicles (EVs) and alternative fuels, such as hydrogen or biofuels, are increasingly being adopted to reduce the environmental footprint of mobility. However, their overall sustainability depends on the lifecycle emissions of the energy sources used to power them, as well as the environmental costs of producing and disposing of batteries and other components.

Key Contributors to Environmental Impact in Transport and Logistics

The environmental impact of transport and logistics is driven by several key factors, each of which contributes to the overall footprint of these sectors. One of the most significant contributors is the energy source used for propulsion. Fossil fuels, such as gasoline, diesel, and heavy fuel oil, dominate the transport sector, accounting for over 90% of its energy consumption. The combustion of these fuels releases CO₂, a primary driver of climate change, as well as other pollutants that degrade air quality. Transitioning to low-carbon or zero-emission energy sources, such as electricity, hydrogen, or advanced biofuels, is essential for reducing these impacts.

Another critical factor is the efficiency of transport modes and vehicles. Fuel efficiency varies widely across different modes of transport, with maritime shipping and rail generally being more energy-efficient per tonne-kilometre (tkm) or passenger-kilometre (pkm) than road or air transport. For example, a freight train can transport goods with significantly lower emissions per tkm than a truck, while a cargo ship is even more efficient for long-distance transport. However, the overall efficiency of a transport system also depends on factors such as load capacity, route optimization, and the use of intermodal transport, which combines multiple modes to minimize environmental impact.

Infrastructure also plays a crucial role in determining environmental outcomes. The construction and maintenance of transport infrastructure, such as roads, bridges, and tunnels, require large amounts of materials, including concrete, steel, and asphalt, all of which have significant environmental footprints. For instance, the production of cement, a key component of concrete, is responsible for approximately 8% of global CO₂ emissions. Additionally, infrastructure projects often lead to land-use changes, such as deforestation or wetland destruction, which can have lasting effects on biodiversity and ecosystem services. Sustainable infrastructure design, such as the use of recycled materials or green construction practices, can help mitigate these impacts.

Behavioral factors, such as consumer demand and corporate practices, also influence the environmental impact of transport and logistics. The growing demand for fast and flexible delivery options, driven by e-commerce and just-in-time manufacturing, has led to an increase in freight transport and last-mile deliveries. This trend has resulted in higher emissions, as well as increased traffic congestion in urban areas. Similarly, corporate logistics strategies, such as the centralization of warehouses or the use of air freight for time-sensitive goods, can amplify environmental impacts. Encouraging sustainable consumption patterns, such as bulk purchasing or slower delivery options, can help reduce the environmental footprint of logistics.

Application Area

• Urban Mobility: The environmental impact of urban mobility is a pressing concern, particularly in rapidly growing cities. Private vehicles, which are often the dominant mode of transport, contribute to air pollution, noise pollution, and greenhouse gas emissions. Public transportation systems, such as buses, trams, and subways, offer a more sustainable alternative, but their effectiveness depends on factors such as coverage, frequency, and energy sources. Electric buses and bike-sharing programs are increasingly being adopted to reduce emissions and improve air quality in urban areas.
• Freight Transport: Freight transport is a major contributor to environmental impact, particularly in the context of global trade. Road freight, which accounts for the majority of freight transport in many regions, is a significant source of CO₂ emissions and air pollutants. Rail and maritime transport are generally more energy-efficient, but their environmental impact depends on factors such as fuel type, load capacity, and route efficiency. Intermodal transport, which combines multiple modes of transport, can help reduce emissions by optimizing the use of each mode.
• Air Transport: Air transport is one of the most energy-intensive modes of transport, with a disproportionately high environmental impact due to the altitude at which emissions are released. While air travel accounts for a relatively small share of global transport emissions, its growth rate is among the highest, driven by increasing demand for passenger and freight services. Efforts to reduce the environmental impact of air transport include the development of more fuel-efficient aircraft, the use of sustainable aviation fuels (SAFs), and improvements in air traffic management to reduce fuel consumption.
• Maritime Transport: Maritime transport is responsible for a significant share of global trade, but it also contributes to environmental impacts such as water pollution, air emissions, and the introduction of invasive species through ballast water discharge. The International Maritime Organization (IMO) has implemented regulations to reduce the environmental impact of shipping, such as the International Convention for the Prevention of Pollution from Ships (MARPOL) and the 2020 sulfur cap, which limits the sulfur content of marine fuels. Additionally, the adoption of alternative fuels, such as liquefied natural gas (LNG) or hydrogen, is being explored to further reduce emissions.
• Logistics and Supply Chain Management: The environmental impact of logistics and supply chain management is influenced by factors such as warehouse location, inventory management, and transportation modes. Sustainable logistics practices, such as the use of green warehouses, optimized routing, and consolidated shipments, can help reduce emissions and improve efficiency. Additionally, the adoption of circular economy principles, such as recycling and reuse, can minimize waste and resource consumption in supply chains.
