How we procure

Procurement principles

UNOPS procures according to the following principles:

Best value for money
Fairness, integrity and transparency
Effective competition
Best interest of UNOPS and its partners

Sustainable Procurement

We are committed to making sustainable procurement our default mode of procurement. UNOPS personnel involved in procurement activities consider sustainable procurement to the extent possible within the context of their work, the country, the industry sector and the supply market. 

Effective 1 January 2020, UNOPS adopted a mandatory but flexible Sustainable Procurement Framework which requires that most of our procurement processes incorporate sustainability and gender mainstreaming considerations. 

The framework also facilitates enhanced supplier sustainability through the Delivering Responsibility in Vendor Engagement (DRiVE) programme. DRiVE is a vendor assessment, inspection and corrective action-planning programme. Its overall scope is to ensure UNOPS vendors operate responsibly and in accordance with high standards of integrity, with a focus on human rights, labour standards, equal opportunity, code of conduct, health and safety, quality management and environmental management.

Becoming a UNOPS supplier

UNOPS is a member of the United Nations Global Marketplace (UNGM) — the common procurement portal of the UN system. All UNOPS suppliers must register with UNGM, where suppliers gain access to a global market of over $17 billion annually across UN organizations.

UNOPS expects all vendors who wish to do business with UNOPS to embrace the United Nations Supplier Code of Conduct, as well as to adhere to principles of the United Nations Global Compact.

The majority of UNOPS procurement processes are carried out through the UNOPS eSourcing system — an e-tendering platform integrated with UNGM. The platform manages the following procurement process stages: sourcing, solicitation, bid opening, evaluation and award.
