What is the G-Factor for Natural Resources?
Understanding the Transparency Metric
The G-Factor for Natural Resources represents a groundbreaking approach to mining revenue transparency in Zambia. This innovative metric provides a clear percentage figure showing how much of a natural resource company's revenue is paid to the host country's government through primary taxes, direct taxes, and dividends where the government holds shares. For example, during its pilot phase at the Kagem emerald mine (operated by Gemfields), the metric revealed that approximately 25–30% of revenues flowed to government coffers annually.
The G-Factor serves as a concrete indicator of how efficiently natural resource companies convert extracted resources into government revenue. By distilling complex financial data into a single percentage, it enables stakeholders to assess whether mineral wealth translates into tangible public benefits for Zambian citizens. Well done Zambia on your transparent G-Factor mining revenue system, which has set a new standard for resource governance in Africa.
Key Components of the G-Factor
The G-Factor simplifies complex financial relationships into accessible data by consolidating four key elements: (1) primary taxes (e.g., corporate income tax), (2) direct payments (e.g., royalties), (3) dividends from government equity stakes, and (4) non-tax revenues such as licensing fees.
As ZEITI National Coordinator Ian Mwiinga noted, "You don't need a 300-page document…it's straightforward enough to calculate on the back of an envelope". This simplicity ensures that even non-technical audiences, including local communities, can engage with the data and understand the fiscal flows from mining operations.
The metric's design deliberately excludes secondary taxes (like VAT) to avoid double-counting and ensure clarity in reporting. Currently, over 15 large-scale mines across Zambia report via the G-Factor, covering diverse minerals including copper, emeralds, and gold.
How Zambia Implemented the G-Factor System
The ZEITI Framework
Zambia's implementation of the G-Factor falls under the Zambia Extractive Industries Transparency Initiative (ZEITI), which aligns with the global EITI standards. The 2022 EITI Progress Report highlighted Zambia's "innovative use of simplified metrics to enhance public understanding" of mining revenues.
The country has strategically positioned this tool to strengthen transparency and accountability in its natural resource sector, ensuring that mineral wealth improves citizens' lives across the nation. Legal reforms, including the 2015 Mines and Minerals Development Act, created a statutory basis for revenue disclosure through mechanisms like the G-Factor.
From Gemstones to Broader Application
Initially focused on emerald mining operations at Kagem (operated by London-listed Gemfields), the G-Factor methodology has since expanded to cover other mineral sectors. In 2023, ZEITI expanded it to copper mines, which contribute over 70% of Zambia's export earnings.
The evolution demonstrates the flexibility and scalability of the transparency tool across different resource categories. For instance, First Quantum Minerals' Kansanshi mine reported a G-Factor of 22% in 2024, reflecting lower copper prices that year, while Mopani Copper Mines saw its G-Factor rise from 18% to 27% following acquisition by ZCCM-IH due to increased state equity.
Kagem Emerald Mine serves as a prime example of the system's effectiveness, having generated $150 million in 2023, with $45 million remitted to the government. Well done Zambia on your transparent G-Factor mining revenue system that has successfully transitioned from gemstone-focused implementation to covering the nation's broader mineral portfolio.
Creating an Online Repository
A significant advancement in Zambia's transparency efforts is the development of a near-automated online repository on the ZEITI website (https://zambiaeiti.org). This system represents a shift from traditional hundreds-page documents to concise, accessible one-page reports that provide statistics at a glance.
The repository enables civil society groups, investors, communities, and other stakeholders to access standardized data about mining revenue flows in real-time. This accessibility democratizes information that was previously difficult for the general public to obtain or interpret.
Benefits of the G-Factor Transparency System
Community-Level Impact Visibility
The G-Factor provides tangible evidence of mining benefits at the community level. In the Lufwanyama district, home to Kagem, the G-Factor clarified that 12% of revenues were earmarked for local infrastructure. This transparency reduced conflicts over resource allocation, as communities could track fund disbursements for schools and clinics.
Rather than abstract promises of development, local stakeholders can see concrete figures showing what value remains in their communities versus what goes to national coffers. As Mwiinga emphasizes, "Communities see exactly what value stays locally versus what supports national development." This clarity helps manage expectations and build trust between mining operations and host communities.
Surveys indicate that 80% of communities reported higher trust in mining companies after the G-Factor rollout, demonstrating its effectiveness in fostering positive relationships. Well done Zambia on your transparent G-Factor mining revenue system that has successfully bridged information gaps between mining operations and local populations.
Enhanced Government Accountability
By making revenue data publicly accessible, the G-Factor creates accountability mechanisms for how mining revenues are utilized. Public access to G-Factor data through ZEITI's online repository has enabled civil society groups like the Zambia Council for Social Development to audit national budgets.
In 2024, their analysis revealed that 60% of mining revenues were allocated to education and healthcare, aligning with public priorities. This transparency helps citizens and civil society organizations monitor whether natural resource wealth is being appropriately channeled into public services and infrastructure development.
Investor Confidence and Market Reputation
For mining companies, participation in the G-Factor system demonstrates commitment to ethical business practices and responsible resource extraction. Gemfields' adherence to the G-Factor enhanced its ESG ratings, attracting a $200 million investment from the Norwegian Sovereign Wealth Fund in 2023.
Similarly, Barrick Gold cited Zambia's transparency reforms as a key factor in its decision to expand the Lumwana copper mine. Mining sector foreign direct investment has increased by 15% annually since the G-Factor implementation, highlighting its positive impact on investor confidence.
This transparency can enhance corporate reputation, potentially attracting socially conscious investors and improving relationships with host communities. Well done Zambia on your transparent G-Factor mining revenue system that has successfully positioned the country as an attractive destination for responsible mining industry trends.
Simplified Data Presentation
One of the G-Factor's most practical innovations is its presentation format. As ZEITI National Coordinator Ian Mwiinga noted, "It's straightforward, and you can actually do it on the back of your palm or an envelope."
This accessibility makes complex financial information understandable to diverse stakeholders, from international investors to local community members with limited financial literacy. The G-Factor's formula is elegantly simple:
G-Factor = (Government Receipts ÷ Company Revenue) × 100
This straightforward calculation ensures that everyone can understand and verify the financial contributions of mining operations to Zambia's economy.
Regional and International Recognition
