Overview

Global Witness is an international non-governmental organisation headquartered in London, with offices in Washington, D.C., and Brussels. It investigates how the exploitation and trade of natural resources can finance armed conflict, enable corruption, damage ecosystems and expose local communities and human-rights defenders to violence. Rather than operating as a conventional consumer-facing brand, Global Witness functions as a research, campaigning and advocacy organisation whose public identity is built around investigative reporting, evidence gathering and pressure for institutional reform. The organisation emerged from work on the illegal timber trade in Cambodia during the 1990s. Its investigations examined how timber was moved across borders while helping finance the Khmer Rouge and how political and business networks benefited from forest exploitation. This early work established a method that has remained central to Global Witness: combine field investigations with documentary evidence, identify the companies and officials involved, publish findings internationally and campaign for governments, banks and industry bodies to change their practices. Global Witness later expanded its focus to diamonds, oil, gas, mining, gold, cocoa and other commodities. Its campaign against conflict diamonds contributed to the creation of the Kimberley Process Certification Scheme, an international system requiring participating governments to certify rough-diamond shipments as conflict-free. The organisation also helped develop the Publish What You Pay movement and played a role in the creation of the Extractive Industries Transparency Initiative, which promotes disclosure of payments and revenues in oil, gas and mining. These initiatives reflect its broader concern that secrecy around resource revenues and ownership allows public wealth to be diverted and abuses to remain hidden. The Democratic Republic of the Congo has been another major area of work. Global Witness has investigated how minerals from the country can support armed groups and has examined the responsibilities of companies whose supply chains connect them to conflict-affected regions. Its wider research has covered forest governance, land concessions, opaque corporate structures, beneficial ownership, financial institutions and the use of offshore or anonymous companies for corruption, money laundering, tax evasion and other illicit purposes. Environmental and human-rights defenders are a central focus of the organisation's recent campaigning. Global Witness documents killings and threats against people resisting land grabs, mining projects, industrial logging, pollution, dams and other forms of resource exploitation. It has reported a long-term rise in killings of environmental and land defenders, including 212 recorded deaths in 2019 and 227 in 2020. The organisation argues that the climate crisis cannot be addressed only through emissions policy: people affected by environmental destruction must have meaningful representation in decisions about climate, land and natural resources, and defenders must be protected from intimidation and violence. Global Witness also campaigns for transparency in political and financial systems. Its work on beneficial-ownership registers seeks to make it harder for individuals to hide assets and conflicts of interest behind shell companies. The organisation has engaged with financial-integrity networks, banking campaigns and anti-corruption coalitions, and has given evidence to policymakers about the role of Western financial institutions in handling proceeds linked to corruption. Its funding comes primarily from grants from foundations, governments and charitable organisations. Global Witness Trust is a registered UK charity supporting the organisation's work. The organisation has received support from bodies including the Open Society Institute, the Norwegian and British governments, the Adessium Foundation and Oxfam Novib. It has received international recognition for investigative activism and social entrepreneurship, including the Gleitsman Foundation Prize, the Skoll Award for Social Entrepreneurship and other awards. Global Witness remains active as an investigative and campaigning NGO focused on accountability in resource industries, corporate ownership, finance and climate-related decision-making.

History

Global Witness was founded in the early 1990s by Patrick Alley, Simon Taylor and Charmian Gooch. Its first major campaign investigated the illegal timber trade in Cambodia, where timber exports connected to the Khmer Rouge and other political and commercial interests helped sustain conflict and deprived the country of public resources. The organisation's field-based reporting attracted international attention and demonstrated the value of tracing natural-resource transactions across borders rather than treating environmental damage, corruption and armed conflict as separate issues. During the late 1990s and early 2000s, Global Witness broadened its investigations to diamonds, oil, gas, minerals, forests and other commodities. Its work on conflict diamonds helped build political pressure for an international certification system. The Kimberley Process Certification Scheme was developed through negotiations involving diamond-producing states, industry participants and civil-society organisations, with Global Witness among the campaigners pressing for controls on rough-diamond shipments linked to armed conflict. The scheme was formally implemented in the early 2000s and required participating countries to certify eligible shipments. The organisation also became involved in campaigns concerning transparency in extractive industries. Global Witness helped establish the Publish What You Pay coalition and contributed to the development of the Extractive Industries Transparency Initiative. The EITI was announced at the 2002 World Summit on Sustainable Development and later received institutional support from the World Bank. Its purpose was to improve disclosure of payments made by oil, gas and mining companies and the revenues received by governments. Global Witness subsequently participated in EITI governance and advisory structures. Conflict minerals became another important strand of work. Research published in 2009 examined how mineral trading in the Democratic Republic of the Congo could finance armed groups and identified risks in the supply chains of companies operating in or sourcing from the region. Global Witness combined field research in the Great Lakes region with analysis of international corporate relationships, arguing that companies and governments outside conflict zones could still bear responsibility for the consequences of opaque sourcing. The organisation's forest work extended from Cambodia to other countries affected by illegal logging, unsustainable exploitation and contested land concessions. It has also examined forests and climate policy, including proposals associated with reducing emissions from deforestation and forest degradation. Global Witness has warned that forest-carbon programmes can harm communities or facilitate misuse of funds unless civil society can independently monitor implementation and affected people have legal and political protections. From the late 2000s onward, Global Witness increasingly focused on financial secrecy and corporate ownership. Its campaigns against anonymous companies promoted public registers of beneficial owners and stronger controls on shell companies. The organisation argued that hidden ownership structures can conceal corruption proceeds, facilitate tax evasion, finance criminal activity and make it difficult to identify who benefits from land, mining and infrastructure transactions. It also engaged with banking and financial-integrity networks and provided evidence to policymakers about the movement of illicit funds through Western financial systems. Global Witness has continued to document threats and killings of environmental and land defenders. Its reporting has linked violence to disputes over mining, logging, plantations, land grabbing, pollution, dams and wildlife protection. By presenting these killings as part of a global accountability problem, the organisation has connected human-rights defence with climate and environmental policy. It campaigns for stronger protection of defenders and for the people most affected by climate and resource decisions to have a greater role in policymaking. The organisation's public profile has been reinforced by awards for international activism, development advocacy and social entrepreneurship. Its work has also generated confrontations with officials and business interests. In Cambodia, reporting on timber networks and alleged links to senior political figures was followed by a reported threat against Global Witness personnel. In Malaysia, an undercover video investigation concerning Sarawak land deals exposed the organisation to scrutiny because of its use of covert methods, while also illustrating its willingness to investigate powerful political and commercial networks. Global Witness is funded mainly through grants from foundations, governments and charities rather than through commercial sales. Its supporting UK charity, Global Witness Trust, is registered in the United Kingdom. The organisation operates internationally from offices in London, Washington, D.C., and Brussels and remains focused on investigative research, public campaigning and policy change at the intersection of natural resources, corruption, environmental protection and human rights.
