Procurement notice

WHO is a specialized United Nations agency with a constitutional mandate as the Directing and Coordinating authority on international health work. Procurement is a critical function in support of the effective discharge of the WHO mandate. In order to fulfill its mandate and achieve its vision WHO must procure a significant volume of goods and services. As a public organization entrusted with donor funds and committed to supporting developing economies, the objective of procurement activities within the WHO is the timely acquisition of goods and services while addressing the following guiding principles;

Best value for money

The overall guiding objective for all WHO procurement is to obtain the best value for money for the Organization. 'Best value for money' is defined as the responsive offer that is the best combination of technical specifications, quality, and price. 'Best value for money' is the result of several factors, including quality, experience, the vendor’s reputation, life-cycle costs, benefits, and parameters that measure how well the good or service allows the organization to meet its social, environmental or other objectives.

Fairness, integrity, transparency, and equal treatment:

The WHO procurement process must allow for transparent competition among prospective providers. All prospective providers must be treated equally. All individuals and entities directly or indirectly associated with the procurement function are responsible for protecting the integrity of the process and maintaining fairness, transparency, and equal treatment of all prospective providers. All potential vendors should be treated equally, and the process should feature clear evaluation criteria, unambiguous solicitation instructions, realistic requirements, and rules and procedures that are easy to understand

In order to promote transparency of the procurement process and accountability, WHO expects its providers to adhere to the principles, and meet the standards, set forth in the UN supplier code of conduct.

Interest of WHO

WHO subscribes to a "Green" procurement policy, WHO will seek to procure goods and services that lessen the burden on the environment in their production, use and final disposal, whenever possible and economical.

To effect “green” procurement, WHO supports the “4 R" strategy to:

• Re-think the requirements to reduce environmental impact;
• Reduce material consumption;
• Recycle materials/waste; and
• Reduce energy consumption

Before finalizing the procurement of goods and/or services, the environmental concerns must be considered, including the following:

• Energy consumption
• Toxicity
• Ozone Depletion
• Radiation

The applicable ecolabel ratings, including Energy Star, EU Ecolabel, etc. should be evaluated to determine how environmentally friendly the goods and/or services are.

The aim is to identify environmentally-friendly ("green") goods and services.
