Green Logistics refers to the sustainable management of logistics activities with the goal of minimizing their environmental impact while maintaining efficiency and service quality. It focuses on reducing the carbon footprint, conserving resources, and adopting eco-friendly practices across transportation, warehousing, packaging, and supply chain operations.

1. Definition

Green logistics is the process of planning, implementing, and controlling the flow of goods, services, and information in a way that meets customer requirements with minimal environmental damage.

2. Objectives of Green Logistics

Reduce greenhouse gas (GHG) emissions from logistics operations.
Lower energy and fuel consumption.
Minimize waste in transportation, warehousing, and packaging.
Promote the use of renewable energy and eco-friendly technologies.
Balance economic efficiency with environmental responsibility.

3. Key Areas of Green Logistics

a) Transportation

Route optimization to reduce travel distance.
Shift to electric or hybrid vehicles.
Use of biofuels or low-emission fuels.
Consolidation of shipments to reduce trips.

b) Warehousing

Energy-efficient lighting (LED) and equipment.
Use of renewable energy sources (e.g., solar panels on warehouse roofs).
Automation to reduce energy waste.
Climate-controlled storage only when necessary.

c) Packaging

Use of recyclable, biodegradable, and reusable materials.
Designing packaging for minimum material use (lightweight packaging).
Returnable packaging systems for suppliers/customers.

d) Reverse Logistics

Collecting and recycling used products or packaging.
Refurbishing and remanufacturing.
Disposal of goods in an environmentally safe manner.

4. Strategies for Implementing Green Logistics

Eco-driving training for drivers to reduce fuel consumption.
Intermodal transport (combining rail, road, and sea for efficiency).
Collaborative logistics (sharing resources among companies to reduce empty runs).
Carbon footprint measurement and reporting.
Green procurement – sourcing from suppliers with eco-friendly practices.

5. Benefits of Green Logistics

Lower operating costs in the long run (fuel savings, reduced waste).
Improved brand image and corporate social responsibility (CSR) profile.
Compliance with environmental regulations.
Increased customer loyalty from eco-conscious buyers.
Contribution to Sustainable Development Goals (SDGs), especially:
- SDG 7 – Affordable and Clean Energy
- SDG 12 – Responsible Consumption and Production
- SDG 13 – Climate Action

6. Challenges in Green Logistics

Higher initial investment in green technology.
Limited infrastructure for electric vehicles and renewable energy.
Complexity in coordinating green initiatives across the supply chain.
Balancing sustainability with cost and delivery speed.

7. Example

Amazon implemented green logistics by:

Using electric delivery vans in urban areas.
Installing solar power systems on fulfillment centers.
Using recyclable packaging for shipments.
Offering customers a “no-rush” delivery option to consolidate shipments and reduce trips

IoT (Internet of Things) in Green Logistics plays a major role in making logistics operations more sustainable by using connected devices, sensors, and real-time data to reduce waste, improve efficiency, and lower environmental impact.

1. Role of IoT in Green Logistics

IoT connects physical logistics assets (vehicles, containers, warehouses, equipment) to the internet so they can collect, share, and analyze data.
This enables:

Real-time monitoring of vehicle performance, routes, and fuel consumption.
Predictive maintenance to avoid breakdowns and reduce waste.
Smart energy management in warehouses.
Better tracking and optimization of shipments to reduce emissions.

2. Key IoT Applications in Green Logistics

a) Smart Transportation

GPS + Telematics: Optimize delivery routes to minimize fuel usage.
Eco-driving monitoring: Sensors track driving behavior (idling, speeding, harsh braking) and provide feedback for fuel-efficient driving.
Load optimization sensors: Ensure trucks are fully loaded before departure to avoid half-empty runs.

b) Cold Chain Monitoring

IoT temperature and humidity sensors maintain the right conditions for perishable goods.
Reduces waste from spoiled goods, lowering environmental and economic losses.

c) Warehouse Energy Management

Smart meters track electricity usage in warehouses.
Automated lighting and climate control adjust based on occupancy and weather.
Solar energy integration with IoT monitoring for maximum efficiency.

d) Asset Tracking

RFID tags and GPS trackers monitor goods in transit.
Reduces losses, theft, and unnecessary re-shipping, which lowers emissions.

e) Predictive Maintenance

Sensors detect wear and tear in vehicles and warehouse machinery.
Repairs are scheduled before breakdowns, avoiding energy waste and downtime.

f) Reverse Logistics Efficiency

IoT-enabled return tracking ensures faster collection and recycling.
Automated sorting systems in warehouses separate recyclable and non-recyclable materials.

3. Benefits of IoT in Green Logistics

Reduced fuel consumption via route and load optimization.
Lower carbon emissions from efficient operations.
Less waste through real-time inventory and condition monitoring.
Better compliance with environmental regulations.
Data-driven sustainability decisions.

4. Example

DHL uses IoT in green logistics by:

Equipping delivery trucks with telematics to track emissions and driver behavior.
Using IoT sensors to manage warehouse lighting and HVAC systems.
Implementing real-time parcel tracking to consolidate routes and avoid unnecessary trips

Carbon Footprint is the total amount of greenhouse gases (GHGs) — mainly carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) — released directly or indirectly into the atmosphere by an individual, organization, product, or activity.
It’s usually measured in CO₂ equivalent (CO₂e), which standardizes all GHGs to the impact of CO₂.

1. In the Context of Logistics

In logistics, the carbon footprint refers to the emissions produced during:

Transportation (trucks, ships, planes, trains).
Warehousing (energy for lighting, cooling, heating).
Packaging (production, disposal).
Material handling (forklifts, conveyors).
Reverse logistics (returns, recycling, disposal).

2. Types of Carbon Footprint

Direct Emissions (Scope 1) – From owned or controlled sources.
- Example: Fuel burned in company trucks.
Indirect Emissions (Scope 2) – From purchased energy.
- Example: Electricity used to run warehouses.
Value Chain Emissions (Scope 3) – From suppliers, customers, and outsourced activities.
- Example: Emissions from a third-party courier.

3. Factors Influencing Logistics Carbon Footprint

Distance travelled and mode of transport.
Vehicle fuel type and efficiency.
Load optimization and backhaul utilization.
Energy source for warehouses (renewable vs. fossil-based).
Type and quantity of packaging materials.
Frequency of shipments (many small vs. fewer large shipments).

4. Ways to Reduce Carbon Footprint in Logistics

Transportation

Use electric, hybrid, or alternative fuel vehicles.
Optimize delivery routes with GPS and AI.
Consolidate loads to avoid empty runs.
Train drivers in eco-driving techniques.

Warehousing

Install LED lighting and energy-efficient HVAC.
Use renewable energy sources like solar panels.
Automate material handling to reduce idle energy use.

Packaging

Use recyclable or biodegradable materials.
Reduce packaging volume and weight.
Implement reusable packaging systems.

Technology

Apply IoT sensors for route optimization.
Use digital twins for supply chain simulation and emission forecasting.

5. Measuring Carbon Footprint

Formula (basic transport example):
$\text{Carbon Footprint (kg CO₂e)} = \text{Distance (km)} \times \text{Fuel consumption (liters/km)} \times \text{Emission factor (kg CO₂e/liter)}$
Tools & Standards:
- GHG Protocol – widely used for corporate carbon accounting.
- ISO 14064 – standards for GHG measurement.
- Online calculators (e.g., Carbon Trust, EPA tools).

6. Example

If a delivery truck consumes 20 liters of diesel over 200 km, and diesel emits 2.68 kg CO₂e per liter:

20 \times 2.68 = 53.6 \text{ kg CO₂e}

That trip adds 53.6 kg CO₂e to the logistics carbon footprint
