Green logistics is quickly gaining importance throughout logistics and supply chain management. Donors and host nations are becoming more aware of environmental issues. Simultaneously, international "green" legislation is being introduced and applied world-wide to all aspects of business including humanitarian supply chains.
This topic aims to introduce logisticians to green logistics aspects and considerations and encourage them to think in "green" terms, to highlight the challenges and to indicate some advantages.
What is Green Logistics ?
Green logistics in the context of humanitarian logistics encourages all stakeholders to consider the impact of their actions on the environment. The main objective of green logistics is to coordinate the activities within a supply chain in such a way that beneficiary needs are met at "least cost" to the environment. It is a principal component of reverse logistics. In the past “cost” has been defined in purely monetary terms, whereas "cost" can now also be understood as the external costs of logistics associated with: climate change, air pollution, dumping waste (including packaging waste), soil degradation, noise, vibration and accidents.
Protecting the environment is especially important in humanitarian logistics, because often a degraded environment (due to conflict, natural disasters or over-use) is one of the reasons a beneficiary community is in need of humanitarian assistance.
Diagram 1: Where-as cost
Green or sustainable logistics is concerned with reducing environmental and other negative impacts associated with the movement and distribution of supplies. Green supply chains seek to reduce negative environmental impact by redesigning sourcing/distribution systems and managing reverse logistics to eliminate inefficiencies.
For example, logistics deals with packaging of materials. Packaging represents one of the greatest challenges to environmentally friendly logistics while at the same time being vital in shipping and storage.
Correct or incorrect packaging has consequences on the transportation, storage and volume of materials in a given space. This can increase the unit cost if the packaging hinders optimization of storage space. Many industries have developed forms of packaging that can perform in transit but do not justify the expense of returning them to the point of origin. This packaging is only used once and then discarded. There should be a responsibility for the supplier and the buyer to recover and recycle or effectively dispose of packaging.
Best practises exist that allow a more sustainable balance between economic, environmental and social objectives.“Green Logistics” is an evolving concept in the world of logistics practice that can be described as an integral transformation of logistics strategies, structures, processes, and systems towards a more rational and effective use of resources.
Sustainability is made up of three pillars: the economy, society, and the environment. These principles are also informally referred as “the 3 Ps” - Profit, People and Planet. By finding a balance among them, logistics can provide the best service while still enforcing and assuring a more conscious resources use.
Green logistics applies a three-dimensional life cycle approach, as opposed to the traditional one-dimensional, economics only focused approach. Following the three-dimensional approach does not necessarily means that the level of effort and times will increase by three. However, as the organisation reduces its impact on the environment and support positive social behaviours, there may be a return on overall “value for money.”
Types of effects
World Bank - Sustainable Procurement (2019)
There is a wide range of initiatives to make logistics as green as possible, and each organisation should evaluate its own goals, capacities and plans to achieve them.
Best practises exist that allow a more sustainable balance between economic, environmental, and social objectives. These might include:
Area of Activity
Steps to Improve
Fleet causing high amounts of pollution, air quality reduced.
Measure the movements, costs and maintenance of transport to gather data about their use. Invest accordingly in proper maintenance depending of the needs and the selected strategy. This might include: redrawing shorter routes, investing in green vehicles, etc.
Lowered emission transport units, well maintained and following repair plans that reduce environmental and economic cost by increasing the efficacy.
Distribution channels not well organised or with big inefficiencies.
Plan supply chain and procurement taking into account the cost to manage the waste produced.
Effectively connect places of production with the distribution points, including using proximity to storage/distribution points as a selection criteria.
Assess the production line or third level distribution channels of your suppliers for waste or misuse.
Faster deliveries, increased flexibility for late requests, and time savings on managing waste.
Price based selection that potentially hides unethical or not environmentally friendly activities.
Create and apply selection criteria that matches the ethical and environmental policies of the organisation.
Research initiatives that other organisations are putting in place and adapt them to your situation.
Product loss by degradation caused by poor storage condition, or damages during in-storage movements.
Make improvements in the infrastructure to facilitate cargo movement. Use solar light and natural ventilation.
If the infrastructure is going to last more than two years, invest in solar or wind power sources and manage your power consumption. (Power Supply section).
Save money and time.
Excessive use of non-biodegradable materials.
Choosing the appropriate mode of transport with enough time, to be able to understand how the cargo is packed and labelled. Try to find a good compromise between safety and handling; Reduce packaging or/and use reusable or biodegradable materials. Example - corrugated cardboard and other forms of paper-based packaging.
Protecting the environment is especially important in humanitarian sector; environmental degradation - due to conflict, natural disasters or over-use - can directly impact the coping mechanisms used by affected population.
This series of questions can be used as a check-list to focus on key areas for consideration in the humanitarian sector:
- What environmental risks do your organisation’s activities pose?
- Do the materials you use pose any danger to the environment, staff or beneficiaries?
- Do you know what impact the material that you supply (including its disposal) and services you provide have on the environment?
- Do you know the quantity or type of waste you produce?
- Do you know how this waste is disposed of or what the cost is?
- Is your organisation operating the most cost-effective method of controlling or eliminating pollution risk?
- Are there hidden benefits such as greater efficiency, or even straightforward business opportunities (for example, commercial utilisation of waste) from adopting alternative methods of controlling or eliminating the pollution risk?
- Are you aware of existing environmental standards and legislation in the country in which you are operating?
- What arrangement do you have for monitoring compliance with environmental legislation?
- Is senior management actively engaged in ensuring that proper attention is given to environmental considerations in your organisation?
- Could you improve your environmental image to the donors and employees?
- Are you highlighting your environmental performance to donors?
Environmental Management Systems (EMS)
Logistics and transport activities have been identified as having a major impact on the environment. Consequently, authorities have started to develop significant legislation at both national and international level has started to be produced. Targets for improving environmental performance have been set by the international community via a range of international agreements and meetings, from the Rio Earth Summit in 1992 to the adoption of the Sustainable Development Goals at Rio+20 in 2015 and the climate change related meetings of the Kyoto Protocol, in particular the Paris Accord, also adopted in 2015. International agreements of particular relevance to logisticians logistics personnel include the Basel-Rotterdam-Stockholm conventions on management of wastes, the Montreal Protocol on protecting the ozone layer (covering substances including air conditioning gases) and the Minamata convention on phasing out mercury.
Environmental impacts are best managed using a systematic approach that helps organizations organisations to understand all their impacts and address them in some sort of priority order. The most common tool is an environmental management system (EMS), and the best known approach to EMS is laid out by the International Organization Organisation of Standards (ISO) 14000 series of standards. The ISO 14000 family addresses various aspects of environmental management and have been adopted by more than 300,000 organizations world wideorganisations worldwide. The very first two three standards deal with environmental management systems (EMS).
- ISO 14001:2015 provides the Guidance for requirements for an EMS.
- ISO 14004:2016 gives general EMS General guidelines on implementation.
- ISO 14005:2019 Guidelines for a flexible approach to phased implementation.
The other standards and guidelines in the family address specific environmental aspects, including:
- performance Performance evaluation;.
- life Life cycle analysis;.
- communication Communication and auditing.
These standards provide a framework for managing environmental issues rather than establishing performance requirements. The process that starts with a senior management commitment and the creation of an environmental policy and leads on to:
- documenting Documenting environmental impacts, prioritising them and setting goals for improvement;planning .
- Planning how stakeholder obligations (including legal requirements) and targets will be met;.
- implementation Implementation (including operational controls);.
- training Training and communicating with staff; and.
- control Control of relevant documentation.
Once an EMS is set up, it is then formally monitored through an auditing process, which will identify any missed targets, procedures not followed or new procedures needed, and document corrective actions required to ensure the EMS meets its objectives. Managers are required to engage in this process and review the system performance of the system on a regular basis. This Performance review may lead to the policy or objectives being changed or updated, in light of the audit reports or changes in circumstances. This process should encourage a commitment to continuous improvement in environmental management as well as ensure that the organisation is not exposed by failing to meet its legal and moral obligations.
Organisations with environmental management systems will attempt to monitor their performance, and simple measures might include:
- miles per gallon of fuel;
- average life of tires (in miles);
- amount of waste lubrication oil generated by the operation;
- utilisation of vehicle load space (expressed as a percentage);
- percentage of miles run by vehicle empty; and
- targets for reducing waste packaging.
Minimising Negative Environmental Impacts
Some key opportunities for improving the sustainability of logistics include:
- Preferencing low-carbon forms of transport (shipping and road transport over air freight, for example)
- Conserving energy and use renewable energy instead of fossil fuels to power premises, especially in remote areas where fuel costs may be very high
- Avoiding wasting water by using simple water efficiency, leak prevention and recycling methods;
- Using interceptor tanks and bunding Volume of fuel used to keep an operations running over a defined period of time, including:
- Operating vehicles.
- Running generators.
- (If possible) fuel used by third party transport providers.
- Proper maintenance and repair of equipment, including:
- Monitoring the changing/degrading performance of generators and vehicles.
- Monitoring consumption of dependant/support equipment (tyres, filters, etc).
- Proper disposal of waste oils and lubricants.
- Proper transport utilisation, including:
- Avoiding sending vessels empty or partially loaded.
- Sharing transport resources with other agencies.
- Understanding international transport needs, especially items transported by air.
- Setting targets for reducing waste reduction, including:
- Minimising spoilage and expiration of stored items.
- Reducing packaging requirements for relief items.
- Environmentally friendly disposal of expired commodities.
- Ensuring a proper disposition plan for all items.
Minimising Negative Environmental Impacts
Sustainable Energy Production
Humanitarian organisations often work in austere, off-grid environments. Using generators that burn petrochemicals is extremely common. While generators may be unavoidable in many contexts, there are steps agencies can take to reduce waste and environmental impact.
- Set standard working hours for generators – generators already have limits to the lengths of time they can operate, and where security permits agencies may choose “off hours” to avoid burning fuel when unnecessary.
- Properly service and maintain generators wherever they are in use. Properly serviced generators also will save money and enhance security.
- Invest in a solar electric or battery backup system to generate and supply electricity to offices and compounds. Battery and solar systems are often great tools to augment power systems, and can be used alongside regular generators.
For more information on the proper methods of maintaining a generator, on selecting and installing a solar electric system, and on using battery back-up systems, please reference the electrical power generation section of this guide.
Sustainable Use of Vehicles
Vehicles are widely used within the humanitarian context, and operating in and around them is almost unavoidable. There many steps to take to ensure the most sustainable and environmentally friendly performance of vehicles. These might include:
- Selecting fuel efficient vehicles and ensuring right-sizing of fleets.
- Driver training to reduce accidents and improve fuel consumption.
- Monitoring fuel consumption.
- Monitoring vehicle utilisation in terms of both payload and empty running.
- Conducting preventative maintenance, as a poorly serviced vehicles use more fuel.
- Dispose of used tyre casings, batteries, motor oil and other vehicle waste responsibly.
A proper maintained fleet has the advantage of being both environmentally friendly, but also cost efficient. For more information on vehicle selection, vehicle and fleet monitoring, and proper maintenance, please reference the vehicle and fleet management section of this guide.
Logistics departments of humanitarian agencies frequently deal with packaging of materials. Packaging represents one of the greatest challenges to environmentally friendly logistics while at the same time being vital in shipping and storage.
Packaging has consequences for transportation, storage methods, and space requirements of a given space. Packaging can increase the unit cost if it hinders optimisation of storage space. Many industries have developed forms of packaging that can withstand the stresses of transport but do not justify the expense of returning them to the point of origin, being used once and then discarded.
Steps to take when planning packaging:
- Plan for biodegradable overpacking such as cardboard cartons.
- Where possible, plan for recovering packing materials, recycling them locally or even returning them to the vendor for re-use. Suppliers and the buyers should seek to recover and recycle or effectively dispose of packaging.
- Reduce the size of packing, requiring less space to store and less fuel to transport.
- Investigate local companies that may engage in environmentally friendly solid waste disposal and recycling.
- Where packing cannot be made from bio-degradable material or material reduced, consider kitting and repackaging into sustainable packing before the last mile of distribution to avoid uncontrolled disbursement of wasteful materials.
Green Facility Management
There are many steps agencies may take to enhance the sustainability of working and living premise and warehouses. These might include:
- Avoiding wasting water by using water efficient taps, leak prevention and recycling methods.
- Install energy efficient light bulbs.
- Using interceptor tanks to avoid run-off pollution from fuel dispensing areas;Careful management and monitoring of other hazardous chemicals on site;.
- Phase out of ozone-depleting gases from air conditioning systems in warehouses and vehicles;Keeping pallet stacks tidy and other measures to reduce spoilage of food and non-food items; andcompounds.
- Develop a strategy for managing e-waste (old computers, communications equipment) and batteries.
In warehouse and stock keeping:
- Utilise proper stock management methods to avoid infestation, spoilage, damage and expiration, all of which lead to waste and disposal.
- Exercise careful management and monitoring of hazardous chemicals to avoid spillage or leaking.
- Taking steps to better manage the production, collection and disposal of waste, including packaging wastes.
For vehicles, minimising factors include:
- selecting fuel efficient vehicles and ensuring right-sizing of fleets;
- driver training to reduce accidents and improve fuel consumption;
- monitoring fuel consumption;
- monitoring vehicle utilisation in terms of both payload and empty running;
- conducting preventative maintenance, as a poorly serviced vehicles use more fuel; and
- dispose of used tyre casings, batteries, motor oil and other vehicle wastes responsibly.
This series of questions can be used as a check-list to focus on key areas for consideration in the humanitarian sector:
- what environmental risks do your organisation’s activities pose?
- do the materials you use pose any danger to the environment, staff or beneficiaries?
- do you know what impact the material that you supply (including its disposal) and services you provide have on the environment?
- do you know the quantity or type of waste you produce?
- do you know how this waste is disposed of or what the cost is?
- is your organisation operating the most cost-effective method of controlling or eliminating pollution risk?
- are there hidden benefits such as greater efficiency, or even straightforward business opportunities (for example, commercial utilisation of waste) from adopting alternative methods of controlling or eliminating the pollution risk?
- are you aware of existing environmental standards and legislation in the country in which you are operating?
- what arrangement do you have for monitoring compliance with environmental legislation?
- is senior management actively engaged in ensuring that proper attention is given to environmental considerations in your organisation?
- could you improve your environmental image to the donors and employees? and
- are you highlighting your environmental performance to donors?
Green logistics should be everyone’s responsibility and there should be commitment from various actors to promote and respect it.

Sustainable procurement is the act of adopting social, economic and environmental factors alongside the typical price and quality considerations into the organisations handling of procurement processes and procedures. CIPS
The procurement process is an excelling time to assess and commit to green logistics practices. Sustainable procurement considers the environmental, social and economic consequences of design, materials used, manufacturing methods, logistics and disposal. In green procurement organisations can meet their needs for goods, services, and utilities in a way that achieves value for money while still addressing principles for sustainable development.
The aim and challenge of sustainable procurement is to integrate environmental and social considerations into the procurement process. One of the most powerful methods is to choose the appropriate selection criteria with sustainability in mind, clearly inform potential bidders, and ensuring all requirements are properly met. A guide to developing solicitations for vendors can be found procurement section of this guide.
Example of selection criteria might include:
Previous/current experience Accreditation by independent certification organisation.
Accreditation by independent certification organisation to a standard.
Impact of materials used and processes of production.
Evidence that workers know their rights and responsibilities at work.
Impact of packaging.
Presence of independent trade unions or effective management/worker committees which address workers’ priorities, including pay, hours and conditions.
Impact of transport (air freight from Europe may be greater than sea freight from Asia/Africa).
Whole-life costing of product
Sub-supplier practices and conditions.
Impact of product life cycle.
Switching cost of current supplier.
Participation in multi-stakeholder initiatives that educate and change practices to address ingrained problems.
CIPS, Chartered Institute of Purchasing and Supply Chain, (2013). Ethical and sustainable procurement.
Ongoing procurement has had such an impact on green logistics that ISO has develop a specific Standard able to guide every procurement decision.
- ISO 20400 Sustainable procurement standard.
Formed ion the bases of ISO 26000 for Social Responsibility, sustainable procurement relies on:
- Assess the organisational “buying culture” - Understand how and from who the organisation buys/sells to, the control over sub-suppliers as well as sub-supplier capacities to accommodate green demands, and if green requirements are realistic and expressed clearly.
- Know the organisation supply chain - Evaluate the cost of the supply chain, and the proportion of the revenue that goes towards paying suppliers. Assess the suppliers societal and environmental impact.
- Think strategically; Consider the risks and opportunities of working more closely with the main suppliers across the whole life cycle of products and services.
- Get buy-in from top management - Ensure key decision makers are on board and aware of the benefits, opportunities, and possible consequences of implementing sustainable procurement into the organisation.
Reverse logistics has been traditionally defined as the process of moving a product from its point of consumption to the point of origin to recapture value or ensure proper disposal. It is one of the fastest developing fields of commercial logistics, resulting continuously changing scope and significance. Reverse logistics includes activities that:
- Avoid return of assets or items.
- Reduces materials in the forward system so that fewer items flow back.
- Ensures the possible reuse and recycling of materials and packaging.
It is important to ensure that aid projects are handled in a responsible manner and that they do not end up causing long term damage to the very people and socieites that they are intended to assist.
Reverse logistics is the management of all the activities involved in the flow of goods, demand information and money in the opposite direction of the primary logistics flow, including reduction in the generation of waste, and management of the collection, transport, disposal, and recycling of hazardous, as well as non-hazardous waste, in a way that maximizes the long-term profitability of the business.
Reverse logistics covers a broad range of items and activities and can include:
- Movement of capital items and equipment to the next emergency response.
- Removal of containers and packaging from an area of intervention.
- Destruction of spoiled food commodities and out of date pharmaceuticals.
- Return of rejected goods to suppliers.
- Movement of excess or over-supplied goods to other programmes or organisations.
Reverse logistics occurs in the humanitarian sector when:
- Downscaling of activities:
- Goods have to be moved to different programmes or disposed.
- Evacuation due to insecurity - may result in the suspension of activities when goods have already been purchased and have to be returned to the supplier or used in other programmes.
- Closing programmes or ending of emergencies prompts the handover of items
- Products are recalled by their manufacturer
- Rejected goods are returned to the vendor due to:
- Incorrect orders.
- Incorrect deliveries.
- Deliveries being delayed and goods no longer useful to the programme.
- Damaged goods.
- Goods on warranty or going for repair.
- Back-trucking of packaging materials for re-use or disposal.
In all instances listed above, there are cost implications that should be taken into consideration during the budgeting and planning period.
