Sustainable Public Procurement in Sao Paulo

Back to Atlas

A state government procurement policy integrating environmental, social, and economic sustainability criteria into all phases of public purchasing to drive sustainable development through the strategic use of government buying power.
What are the main aims and objectives?

The Sustainable Public Procurement (SPP) policy of São Paulo State aims to use the state government's annual purchasing power of approximately USD 12 billion—deployed across more than 1,800 procuring units—as a strategic tool to promote sustainable development. The policy responds to the challenge that governments often undertake major procurement decisions without systematically considering environmental and social impacts. SPP was created to embed sustainability throughout the entire procurement process, from initial needs identification through supplier management and contract monitoring. The program operationalizes nine explicit sustainability criteria established by state policy: incentives for social policies, enhanced transparency in management, savings in water and energy consumption, waste generation minimization, rationalization of raw material use, pollutant emission reduction, adoption of technologies with less environmental impact, use of low-toxicity products, and adoption of technologies with lower greenhouse gas emissions. By integrating these criteria into procurement specifications and supplier requirements, São Paulo aims to drive sustainable patterns of production and consumption across public and private sectors while simultaneously improving government efficiency and procurement transparency.

How does the program work?

The Sustainable Public Procurement program integrates sustainability criteria throughout six key procurement phases, beginning with needs identification and culminating in contract monitoring and supplier enforcement.​

During the specification phase, sustainability criteria are embedded in technical descriptions for three procurement categories. For goods, specifications mandate high-efficiency light bulbs with lowest mercury content, cables and wires with high electrical efficiency, and products with low lead and polyvinyl chloride (PVC) content. For services, requirements include water and energy efficiency, waste management plans, reduced chemical use, and greenhouse gas mitigation opportunities. For construction works, environmental and social requirements are integrated into project specifications and contract terms.​

Rather than incorporating socio-environmental criteria in the competitive bidding phase—which could introduce subjectivity and corruption risks—the program applies them comprehensively during the preparatory phase through standardized technical specifications. Electronic reverse auctions are used to achieve cost efficiency, with suppliers selected based on price while compliance with pre-established sustainability standards is mandatory throughout contract execution.​

The program employs several supporting tools and mechanisms. A Socio-Environmental Label identifies goods and services meeting sustainability criteria, tracked in the Cadmat (Registry of Goods and Services). An electronic sanctions registry maintains a publicly accessible blacklist of suppliers prohibited from procurement due to socio-environmental non-compliance, ensuring accountability without requiring constant government monitoring. Cadmadeira provides specific tracking for legal forest products to prevent illegal Amazon timber procurement. An electronic procurement exchange (BEC/SP) conducts reverse auctions achieving average cost savings of approximately 20% compared to reference prices.​

Government capacity building is central to implementation. The state invested significantly in distance learning courses training thousands of public servants on sustainability concepts, procurement procedures, and change management to internalize sustainable purchasing practices across government entities.

What is the overall cost?

There is currently no information about the cost of the program. 

How was it implemented?

The Sustainable Public Procurement policy emerged from decades of state government modernization efforts beginning in the mid-1990s. After achieving fiscal equilibrium and eliminating a budget deficit that had represented 21.7% of total state revenue in 1994, the state government intensified modernization of public management systems through investment in information and communication technology, developing new management tools and procurement systems.​

In 2004, the Public Management Quality Committee formally requested a feasibility study on developing an SPP policy. This led to the establishment through Resolution CC-53/04 of a temporary Working Group (WG-2004) composed of approximately 40 professionals representing the Office of the Chief of Staff, Environment Secretariat, Economy and Planning Secretariat, Treasury Secretariat, Energy/Water/Sanitation Secretariat, Office of the State Attorney General, and state technical agencies. Three working subgroups addressed specific procurement categories: General Services, Goods, and Construction Works and Engineering Services.​

A comprehensive legal framework was developed, building on national Brazilian procurement law and including Decrees establishing mandatory sustainability measures for light bulbs, water consumption rationalization, environmental criteria, climate change policies, and regulations for coordinating SPP initiatives. By 2011, the initially temporary Working Group was made permanent through Joint Resolution No. 1/11, reflecting the program's maturation and institutional commitment to sustainability integration.​

Implementation proceeded through development of the Cadmat registry, the electronic procurement exchange (BEC/SP), the Socio-Environmental Label marking system, and the Cadmadeira registry for legal timber tracking. Sustained capacity building through distance learning ensured that government officials across entities understood and could implement SPP concepts and practices.

What impact has been measured?

From 2008 to 2009, transactions involving items with the Socio-Environmental Label increased from 16.03% to 24.15% within assessed goods groups. Overall sustainable purchases increased from 2.13% of total goods purchased in 2008 to 3.33% in 2009, demonstrating that the program successfully signaled market demand for sustainable products to suppliers.​

Electronic reverse auctions achieved average savings of 20% compared to reference prices. From 2003 to 2011, cumulative savings totaled approximately BRL 14.4 billion (USD 8.7 billion). Electronic systems reduced procurement time dramatically, with half of auctions completed in 11 days and three-quarters completed in 13 days, compared to months for traditional competitive procurement methods.

What lessons can be learned?
  • Challenge in quantifying socio-environmental benefits: The Treasury Secretariat faces difficulties in quantifying and comparing socio-environmental benefits against immediate costs, limiting ability to justify expenditures and rationalize trade-offs.​
  • Limited construction and engineering services integration: Construction works procurement, representing a major spending category, remains underutilized for sustainability integration compared to goods and services, restricting potential environmental impact.​
  • Modest proportion of total procurement: Sustainable purchases represented only 3.33% of total goods procurement by 2009, suggesting the program affects a relatively small portion of total government spending despite years of implementation.​
  • Limited measurement of long-term environmental outcomes: Comprehensive lifecycle assessment benefits and final environmental impact are not systematically documented, creating uncertainty about whether procurement decisions generate meaningful environmental change.​
  • Knowledge gaps on supplier transformation: The extent to which the program has transformed supplier practices beyond compliance with procurement specifications remains unclear, raising questions about market-wide sustainability changes.​
  • Decentralized implementation challenges: With more than 1,800 procuring units, ensuring consistent application of SPP criteria across government proved challenging, requiring ongoing coordination and harmonization efforts.​
  • Lessons for replication: The Sao Paulo experience demonstrates that embedding sustainability criteria in standardized technical specifications rather than in bidding phases reduces subjectivity concerns while still achieving sustainability integration; that electronic procurement systems enhance transparency and efficiency; and that government scale and sustained political commitment are essential for meaningful market transformation.

About public procurement programs (excerpt from Nesta's ‘Idea Bank’ for Local Policymakers):

According to one estimate, within the EU around 19% of GDP is spent on public procurement, making it one of the most powerful tools that governments have at their disposal to stimulate startups and SMEs. Undoubtedly, procurement contracts can make a huge difference to small firms.

Unfortunately, procuring from public entities is often a long, cumbersome and painful process, especially for small businesses with more limited expertise and resources. As a consequence, these processes tend to favour incumbents, lower the level of competition and increase market inefficiencies. On their side, public bodies may also find procuring from startups to be more challenging than from established businesses, potentially involving higher risk and lower levels of certification and awareness. However, startups can often bring innovative solutions to the table, widely improving value for citizens and employees. Making procurement processes more accessible can therefore benefit both sides.

This can be accomplished by a variety of means, including: creating procurer networks, ‘meet the market’ events and easier points of contact, to help small suppliers find buyers; educating procurement officers about the benefits of smaller suppliers and the need to avoid over-specifying contracts (thus allowing for innovative solutions); increasing transparency of the organisation’s needs (thus allowing potential suppliers to be aware of supply possibilities before formal calls); encouraging subdivision of big contracts into smaller pieces; simplifying the qualification process; resisting demands for ISO certification for smaller suppliers; educating potential suppliers about the process; and allocating a portion of overall procurement budget to be spent with smaller companies.
