Why are treaties and standards important for sustainability in procurement?

  • Treaties and standards are important for sustainability in procurement because they help organizations follow clear rules for environmental protection, human rights, ethical sourcing, and responsible supply chains.
  • Sustainability treaties and standards guide procurement teams in choosing suppliers that meet social, environmental, and governance requirements.
  • Treaties and standards support sustainable procurement by reducing risk, improving transparency, and helping companies align purchasing decisions with global sustainability goals.

10 Treaties for Sustainability in Procurement

Treaties and international standards provide a common framework for making procurement more sustainable, transparent, and responsible. They help organizations align supplier selection, sourcing decisions, and contract requirements with environmental protection, ethical labor practices, and long-term sustainability goals.

1. Paris Agreement

The Paris Agreement is an international climate treaty adopted in 2015 to limit global warming and strengthen the global response to climate change. It asks countries to define climate targets, reduce greenhouse gas emissions, and improve adaptation to climate-related risks. Because it creates a common global direction for climate action, it strongly influences how companies and public institutions define their sustainability goals.

In sustainable procurement, the Paris Agreement is important because it encourages organizations to consider carbon emissions across the supply chain. Procurement teams can use it as a basis for selecting suppliers that reduce energy consumption, use renewable energy, report emissions, or offer low-carbon products. In this way, purchasing decisions become connected with climate goals and long-term decarbonization strategies.

2. United Nations Framework Convention on Climate Change — UNFCCC

The UNFCCC is the main global framework for international cooperation on climate change. It was adopted in 1992 and serves as the foundation for later climate agreements, including the Kyoto Protocol and the Paris Agreement. Its main purpose is to coordinate global efforts to reduce dangerous human impact on the climate system.

For procurement, the UNFCCC is important because it supports the integration of climate criteria into business and public purchasing decisions. Organizations can use their principles to evaluate suppliers based on emissions, climate risk, energy efficiency, and environmental responsibility. This helps procurement move from a purely cost-based function toward a strategic role in climate action.

3. Basel Convention

The Basel Convention focuses on the control of transboundary movements of hazardous waste and its disposal. Its main objective is to protect human health and the environment from the negative effects of hazardous and other waste streams. It is especially relevant for waste such as hazardous industrial waste, certain plastic waste, household waste, and electronic or electrical waste.

In sustainable procurement, the Basel Convention helps organizations avoid suppliers that manage waste irresponsibly or transfer environmental risks to weaker regulatory environments. It is particularly important when purchasing electronics, chemicals, packaging, batteries, or materials that may generate hazardous waste. Procurement teams can use it to require responsible waste treatment, traceability, recycling practices, and compliance with environmental regulations.

4. Stockholm Convention on Persistent Organic Pollutants

The Stockholm Convention is focused on persistent organic pollutants, often called POPs. These are dangerous chemicals that remain in the environment for a long time, can travel across borders, accumulate in living organisms, and harm human health and ecosystems. The convention aims to eliminate or restrict the production and use of these substances.

For sustainable procurement, this convention is important because many products, materials, and industrial inputs may contain harmful chemicals. Procurement teams can use it when defining technical specifications for packaging, textiles, electronics, pesticides, cleaning products, and manufacturing materials. This supports safer sourcing, chemical risk reduction, and the selection of suppliers that follow strict environmental and health standards.

5. Rotterdam Convention

The Rotterdam Convention regulates international trade in certain hazardous chemicals and pesticides through the prior informed consent procedure. This means that countries should receive information and give consent before specific hazardous chemicals are exported to them. The convention promotes shared responsibility between exporting and importing countries in protecting human health and the environment.

In procurement, the Rotterdam Convention is relevant because it supports transparency in the purchase and movement of hazardous chemicals. Organizations can use it to check whether suppliers provide proper documentation, safety data, and legal compliance for chemicals and pesticides. This helps procurement teams reduce environmental, health, legal, and reputational risks connected with dangerous substances.

6. Minamata Convention on Mercury

The Minamata Convention on Mercury is a global agreement focused on reducing mercury pollution and protecting human health and the environment. Mercury is dangerous because it can contaminate air, water, soil, food chains, and industrial systems. The convention addresses human activities that contribute to mercury pollution and aims to reduce mercury use and releases over time.

For sustainable procurement, this treaty is important when organizations buy products, equipment, raw materials, or services that may involve mercury. This can include lighting, measuring devices, industrial processes, waste handling, mining-related materials, and some healthcare or laboratory products. Procurement teams can use Minamata-related requirements to avoid mercury-containing products, choose safer alternatives, and demand responsible supplier practices.

7. Convention on Biological Diversity — CBD

The CBD has three main objectives: conserving biodiversity, using biological resources sustainably, and sharing benefits from genetic resources fairly. It covers biodiversity at the level of ecosystems, species, and genetic resources. Because biodiversity is directly connected with natural resources, land use, agriculture, forestry, and raw materials, the convention is highly relevant for sustainable development.

In procurement, the CBD is important because many supply chains depend on nature-based resources. Procurement teams can use these principles when sourcing food, wood, paper, textiles, cosmetics, agricultural products, and natural raw materials. This helps organizations avoid suppliers linked to deforestation, habitat destruction, biodiversity loss, or unsustainable extraction of resources.

8. CITES

CITES is the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Its purpose is to regulate or prohibit international trade in species that are threatened by overexploitation. It applies to many types of animal and plant species, as well as products derived from them.

For sustainable procurement, CITES is important because it helps organizations avoid illegal or unethical sourcing of wildlife-based materials. This can include timber, leather, exotic plants, animal-derived ingredients, decorative products, and other natural materials. Procurement teams can use CITES compliance as a requirement for supplier selection, product documentation, and responsible sourcing policies.

9. Montreal Protocol

The Montreal Protocol is a global agreement created to protect the ozone layer by phasing out substances that deplete it. It controls the production and consumption of ozone-depleting substances, such as certain chemicals used historically in refrigeration, air conditioning, foams, and aerosols. The agreement was signed in 1987 and entered into force in 1989.

In procurement, the Montreal Protocol is important when purchasing cooling equipment, HVAC systems, insulation materials, aerosols, and chemical-based products. Procurement teams can use it to require ozone-safe technologies and avoid products based on banned or restricted substances. This supports environmental compliance, climate responsibility, and safer product selection.

10. ILO Fundamental Conventions

The ILO Fundamental Conventions define key labour standards related to basic rights at work. These include freedom of association, collective bargaining, the elimination of forced labour, the abolition of child labour, non-discrimination, and equal remuneration. They are central to social sustainability because they protect workers in national and global labour markets.

In sustainable procurement, ILO conventions are important because suppliers should not be evaluated only by price and technical quality. Procurement teams can use these labour standards in supplier codes of conduct, audits, contracts, and social compliance requirements. This helps organizations reduce the risk of forced labour, child labour, unsafe working conditions, discrimination, and unethical practices in the supply chain.

10 Standards for Sustainability in Procurement

Sustainability standards help organizations turn general sustainability goals into clear procurement requirements, supplier criteria, and measurable practices. They support better control of environmental impact, social responsibility, ethical sourcing, product traceability, and long-term supply chain performance.

1. ISO 20400 — Sustainable Procurement

ISO 20400 is one of the most directly relevant standards for sustainability in procurement. It provides guidance on how organizations can integrate sustainability into procurement policies, strategies, processes, and supplier relationships. The standard is not a certification standard, but a practical framework for improving procurement decisions from environmental, social, and economic perspectives.

In procurement, ISO 20400 helps organizations move beyond price-based purchasing and include sustainability risks and impacts in decision-making. It supports supplier evaluation, responsible sourcing, life-cycle thinking, and stakeholder engagement. This makes it useful for companies that want to align procurement with ESG goals and long-term value creation.

2. ISO 14001 — Environmental Management Systems

ISO 14001 is an international standard for environmental management systems. It helps organizations identify, manage, monitor, and improve their environmental responsibilities in a structured way. The standard is widely used because it supports continual improvement in environmental performance.

For procurement, ISO 14001 is important because buyers can use it as a supplier qualification or evaluation criterion. Suppliers with ISO 14001 certification are more likely to have systems for managing waste, emissions, resource use, and environmental risks. This helps procurement teams reduce environmental impacts across the supply chain.

3. ISO 26000 — Social Responsibility

ISO 26000 guides social responsibility for organizations of different sizes, sectors, and locations. It covers themes such as human rights, labour practices, environmental responsibility, fair operating practices, consumer issues, and community involvement. Unlike some ISO standards, it is guidance-based and not intended for certification. 

In sustainable procurement, ISO 26000 is useful because it helps organizations understand the broader social and ethical impacts of purchasing decisions. Procurement teams can use these principles when creating supplier codes of conduct, responsible sourcing policies, and sustainability requirements. It is especially relevant when evaluating suppliers in terms of labour rights, ethics, transparency, and social impact.

4. ISO 50001 — Energy Management Systems

ISO 50001 is an international standard focused on energy management. It provides a practical framework for improving energy performance through an energy management system. The standard helps organizations use energy more efficiently, reduce energy costs, and lower environmental impacts.

In procurement, ISO 50001 is important when organizations purchase energy-intensive products, equipment, services, or production inputs. Procurement teams can give preference to suppliers that manage energy consumption systematically and invest in energy efficiency. This supports lower greenhouse gas emissions and contributes to more sustainable supply chain operations.

5. ISO 14064 — Greenhouse Gas Accounting and Reporting

ISO 14064 is a standard related to greenhouse gas emissions measurement, reporting, and verification. ISO 14064-1 focuses on organization-level quantification and reporting of greenhouse gas emissions and removals. It helps organizations create reliable GHG inventories and improve transparency in climate-related reporting.

For procurement, ISO 14064 is useful because supply chains often represent a large share of total emissions. Buyers can use this standard when asking suppliers to measure, verify, and report their greenhouse gas emissions. This makes procurement decisions more transparent and supports climate-focused supplier selection.

6. ISO 14067 — Carbon Footprint of Products

ISO 14067 provides principles, requirements, and guidelines for calculating and reporting the carbon footprint of products. It is based on life-cycle assessment principles and considers emissions connected with different stages of a product’s life cycle. This makes it useful for understanding the climate impact of products, not only organizations.

In procurement, ISO 14067 helps buyers compare products based on carbon footprint and life-cycle emissions. It can be used when choosing materials, packaging, equipment, transport services, or finished goods. This supports low-carbon purchasing and helps organizations reduce emissions embedded in purchased products and services.

7. ISO 45001 — Occupational Health and Safety Management Systems

ISO 45001 is an international standard for occupational health and safety management systems. It helps organizations provide safe and healthy workplaces by managing risks and preventing work-related injuries and ill health. The standard is applicable to organizations of different sizes, sectors, and risk levels.

For sustainable procurement, ISO 45001 is relevant because supplier sustainability also includes worker safety. Procurement teams can use it to assess whether suppliers have proper health and safety systems in place. This reduces social risk in the supply chain and supports responsible supplier management.

8. SA8000 — Social Accountability Standard

SA8000 is a global social certification standard focused on fair and decent treatment of workers. It covers areas such as child labour, forced labour, health and safety, freedom of association, discrimination, working hours, and remuneration. It is widely used as a framework for improving labour conditions and social accountability.

In procurement, SA8000 is important because it helps buyers evaluate the social performance of suppliers. It is especially useful in global supply chains where labour risks may be harder to monitor directly. Procurement teams can use the SA8000 certification or requirements to support ethical sourcing and reduce the risk of worker exploitation.

9. FSC Chain of Custody Certification

FSC Chain of Custody Certification verifies that forest-based materials are properly identified and controlled through the supply chain. It helps confirm that certified materials come from responsibly managed forests, controlled sources, reclaimed materials, or approved mixtures. This is particularly relevant for wood, paper, packaging, furniture, and other forest-based products.

In sustainable procurement, FSC is important because it helps buyers avoid products linked to illegal logging, deforestation, or poor forest management. Procurement teams can require FSC-certified products when purchasing paper, timber, packaging, office supplies, or construction materials. This supports biodiversity protection, responsible resource use, and supply chain traceability.

10. Fairtrade Standards

Fairtrade Standards provide requirements for actors in Fairtrade supply chains, including producer organizations, farms, factories, traders, and companies. They include social, economic, and environmental criteria designed to support fairer and more sustainable trade. These standards are especially relevant for agricultural products such as coffee, cocoa, tea, sugar, bananas, cotton, and similar commodities.

In procurement, Fairtrade Standards help organizations source products in a way that supports fair prices, better working conditions, and more responsible production. Buyers can use Fairtrade certification as evidence that suppliers meet defined sustainability and ethical trade requirements. This is useful for organizations that want to connect procurement with social impact, responsible sourcing, and transparent supply chains.
