What Diagonal does

Diagonal is a Brazilian socio-environmental management consultancy founded in 1990 in Recife, Pernambuco, providing professional services to government agencies and private companies across multiple Brazilian states and internationally in Mozambique. The firm serves two primary customer segments: public sector clients (municipal, state, and federal agencies) requiring support for land regularization, social housing, sanitation, and urban planning; and private sector clients in mining, petrochemical, steel, energy, pharmaceutical, and infrastructure sectors seeking ESG strategy, community relations, environmental licensing, and crisis management. With 501–1,000 employees, Diagonal delivers projects spanning the full socio-environmental management lifecycle, from diagnostic and planning through execution and monitoring, and operates across offices in Recife (founding location), São Paulo (primary operational HQ), and Maputo.

Diagonal's service portfolio is built around an interdisciplinary methodology that combines social and digital technologies — including georeferencing, digital and georeferenced socioeconomic registration systems, and managerial information systems with dashboards — with conventional consulting expertise. Core service lines include Land Regularization, Sanitation Solutions (incorporating the condominium sanitation method acquired via Condominium in 2012), Community Relations, Territorial Intelligence, Resettlement Services, Environmental Licensing, ESG Consulting, Social Technical Work, Program Management, Crisis Prevention and Management, Urban Planning, Environmental Education, and Peripheral Territory Management. The firm's proprietary methodologies, notably the social urbanism approach developed through the Tamarutaca project in the early 1990s, served as benchmarks for Brazilian national programs such as Habitar Brasil.

Diagonal generates revenue through professional services contracts: public sector engagements procured via public tenders and private sector agreements negotiated directly with corporate clients. The firm holds ISO 9001 certification (the first in its segment) and B Corporation certification (since 2019), with LGPD compliance formalized under its corporate governance framework. Its GTM motion is sales-led and event-driven, combining direct commercial outreach through a dedicated commercial director and sustainability leadership with active participation in industry conferences such as LatinoSan, ABEEólica, and ABIFINA. The firm has built long-tenured anchor relationships with major clients including Vale, Braskem, SABESP, CDHU, and SEHAB-SP.

Emerging players

• Sustainalytics: Global ESG research and ratings firm providing sustainability analytics to institutional investors and corporates. Comparable to Diagonal's ESG advisory practice from a corporate-buyer's perspective, but focused on ratings/research rather than field-level social management and resettlement.

Comparable to Diagonal in water/sanitation and environmental consulting, particularly on international development-bank-funded projects in Latin America and Africa.
