Revolutionizing ESG Due Diligence
Norway’s $2 trillion oil fund, managed by Norges Bank Investment Management (NBIM), has taken a decisive step in integrating artificial intelligence into its investment screening process. Established in the 1990s to channel oil and gas revenues into global markets, NBIM now employs sophisticated AI tools to evaluate reputational and ethical risks across its vast portfolio.
Enhancing Investment Screening With AI
NBIM has adopted Anthropic’s Claude AI model as part of its ESG due diligence process, according to reports indicating the initiative began in late 2024. The system analyzes large volumes of publicly available information beyond traditional data-provider metrics.

The goal is to help portfolio managers identify potential risks such as labor violations, corruption, or fraud earlier in the investment cycle. Officials say the approach supports faster risk assessment and allows the fund to react more quickly when concerns emerge.
Global Influence And Strategic Investments
NBIM is one of the world’s largest institutional investors, with holdings in more than 7,200 companies across 60 countries and ownership of roughly 1.5% of all publicly listed equities globally.
Its portfolio includes major technology companies such as Nvidia, Apple, and Microsoft, reflecting a strategy that combines long-term financial performance with sustainability-focused risk management.
Addressing Ethical Complexities
The fund’s ethical framework has attracted international attention, particularly following decisions to divest from certain companies, including Caterpillar and several Israeli banks. The moves prompted debate over how institutional investors balance financial risk assessment with broader ethical considerations.
Norwegian Finance Minister Jens Stoltenberg has said the decisions were based on financial criteria rather than political considerations. NBIM is currently operating under temporary guidelines while a government-appointed ethics committee reviews its exclusion and observation processes.
A Vision For The Future
NBIM CEO Nicolai Tangen said in an interview that AI is becoming increasingly important in investment analysis, particularly when evaluating markets where reliable local information may be limited.
By integrating large-language models into research workflows, the fund aims to improve how ESG risks are identified and monitored, reinforcing the role of technology in modern asset management.
With assets valued at around $2.2 trillion, NBIM’s adoption of AI reflects a broader trend among large institutional investors toward combining data-driven analysis with sustainability-focused investment strategies.
