Overview
Pöyry was a Finnish engineering and management-consulting group whose roots lay in forestry and forest-products engineering. Founded in 1958 by Jaakko Pöyry, the firm developed from a small Finnish engineering office into an international consultancy serving industrial companies, public authorities, utilities, and infrastructure owners. Its historical specialization in pulp, paper, and other forest industries provided the foundation for expansion into energy, chemicals and biorefining, mining and metals, transportation, water, and related industrial services. The company operated through a combination of global sector expertise and local engineering capabilities. Its work included feasibility studies, technical design, environmental and regulatory support, procurement assistance, construction supervision, project management, operational improvement, and management consulting. The group reported activity in more than 100 countries and maintained offices in over 45 countries, with approximately 6,000 experts at the height of its international operations. Its four principal business groups were Energy, Industry, Regional Operations, and Management Consulting. Pöyry participated in a broad range of major infrastructure and industrial projects. Examples cited in descriptions of the company include the Gotthard Base Tunnel in Switzerland, the Ras Al-Khair combined power and desalination plant in Saudi Arabia, the Xayaburi hydropower project in Laos, Vantaa Energy's waste-to-energy facility in Finland, the Emscher sewage system in Germany, the Eldorado pulp mill in Brazil, and the Lillgrund offshore wind farm in Sweden. These assignments illustrated the firm's positioning as a technical adviser and project-services provider rather than as a manufacturer or infrastructure owner. The business traded under the Jaakko Pöyry Group name for much of its earlier history and adopted the shorter Pöyry name in 2006. It was listed on Nasdaq Helsinki as Pöyry PLC and reported 2015 net sales of €575 million. In the later 2010s, the company became part of a consolidation of Nordic engineering and technical-consulting firms. Swedish ÅF and Pöyry combined in 2019, creating AFRY. Following that transaction, Pöyry ceased to exist as an independent listed group, although its expertise, personnel, projects, and market presence continued within AFRY. The Pöyry website and historical references therefore describe a predecessor brand and organization rather than a currently independent operating company.
History
Pöyry was established in Finland in 1958 by Jaakko Pöyry. Its original growth was closely associated with the forest-products sector, particularly the engineering requirements of pulp and paper production. This specialization gave the company a strong technical base in process industries and helped it build relationships with industrial clients beyond Finland. Over time, the business broadened from engineering design into consulting, project management, operational advice, and multidisciplinary technical services. The organization expanded internationally as forest-industry companies and infrastructure developers pursued projects across national borders. Its work increasingly covered the complete lifecycle of large projects, from early feasibility and investment studies to engineering, procurement support, construction supervision, commissioning, and performance improvement. Although forest industries remained an important part of its identity, Pöyry also developed practices serving electricity generation and networks, chemicals and biorefining, mining and metals, transportation, water, and environmental infrastructure. The company was historically known as the Jaakko Pöyry Group. In 2006 it changed its name to Pöyry, simplifying the brand used across its international operations. The group operated through Energy, Industry, Regional Operations, and Management Consulting business groups. Its regional network extended to more than 45 countries, while projects and assignments were carried out in more than 100 countries. The combination of international sector practices and local engineering offices was central to its business model. Pöyry's project portfolio included technically demanding infrastructure and industrial developments. Cited examples include work connected with the Gotthard Base Tunnel in Switzerland, the Ras Al-Khair power and desalination plant in Saudi Arabia, the Xayaburi hydropower project in Laos, the Vantaa Energy waste-to-energy plant in Finland, the Emscher sewage system in Germany, the Eldorado pulp mill in Brazil, and the Lillgrund offshore wind farm in Sweden. These examples span transportation, utilities, renewable and conventional energy, water, and pulp production, reflecting the breadth of the group's engineering activities. Pöyry became a public company and its shares were traded on Nasdaq Helsinki. The company reported net sales of €575 million in 2015, although this figure describes a historical reporting period and not the present organization. Martin à Porta was identified as President and Chief Executive Officer from 1 January 2016. During the same period, the group faced scrutiny over work associated with the Xayaburi hydropower project in Laos and a separate World Bank sanction involving Pöyry Finland. Finnish authorities concluded in 2013 that the company's conduct in the Xayaburi matter complied with applicable OECD corporate-responsibility guidelines, while the World Bank sanction in 2015 concerned administrative-rule violations in a Vietnam water-sector project. The decisive corporate change came in 2019, when Pöyry merged with Swedish engineering group ÅF. The combined company became AFRY. Consequently, Pöyry is best understood today as a historical Finnish engineering brand and predecessor organization whose capabilities and personnel were incorporated into AFRY, rather than as an independent active company.

Controversies
2015
World Bank debarment of Pöyry Finland
Pöyry Finland and its subsidiaries were debarred from World Bank-financed projects for one year after the World Bank identified four cases of fraudulent practices connected with a 2008 Vietnam water-sector project. Pöyry said the sanction concerned Pöyry Finland, a successor to Pöyry Environment Oy, and did not apply to Pöyry PLC or other subsidiaries. The company also stated that no unlawful conduct by Pöyry Finland or its employees had been identified in the matter.
2012
NGO complaint concerning the Xayaburi hydropower project
Several NGOs filed a complaint with Finland's Ministry of Employment and the Economy concerning Pöyry PLC and its Swiss subsidiary Pöyry Energy AG. The complaint concerned Pöyry's technical review of the controversial Xayaburi Dam project in Laos and questions about compliance with Mekong River Commission guidelines. The ministry later concluded that Pöyry complied with OECD guidelines and had acted to mitigate environmental impacts, while noting that Pöyry was not responsible for the project's environmental and social impact assessment or the final decision to proceed.
