Climate Action Plan

Botswanamark Diamonds commits to supporting the global ambition to limit global warming to 1.5°C, in line with the Paris Agreement.

1. Commitment and focus

Botswanamark recognises that:

  • The primary climate impacts in its value chain occur at the mining stage.
  • As a brand, its most effective role is to measure, offset, influence, and support transition efforts across the value chain.

This Climate Action Plan therefore focuses on:

  • Accurate measurement of climate impacts.
  • Targeted offsetting of unavoidable emissions.
  • Support for supplier-led decarbonisation.
  • Governance, transparency, and stakeholder engagement.
2. Climate baseline and emissions context

2.1 Mining-stage carbon footprint (Scope 3 - upstream)

  • The approximate carbon footprint of mining a 1 carat natural diamond is 160 kg CO2.
  • In 2025, Botswanamark sold 416 carats.
  • This results in an estimated Scope 3 upstream footprint of approximately 66 tonnes CO2.

This footprint represents an actual and material climate impact, driven by the inherent energy intensity of mining.

2.2 Carbon offsetting through Zamazama ovens (Botswana)

To address this impact, Botswanamark offsets the mining-related carbon footprint through the use of Zamazama ovens in Botswana, which:

  • Reduce reliance on traditional fuel sources.
  • Deliver social and environmental co-benefits.
  • Each offset approximately 4 tonnes of CO2.

Offsets are scaled to fully address the estimated Scope 3 emissions associated with Botswanamark diamond sales, ensuring that the climate impact of mining is actively mitigated rather than ignored.

This approach prioritises:

  • Local impact within Botswana.
  • Direct linkage to the mining geography.
3. Value-chain transition context - Debswana

Botswanamark recognises and supports Debswana's long-term climate transition strategy, including:

  • A stated ambition to become carbon neutral by 2030.
  • Investment in solar farm development.
  • Increased use of biofuels.
  • Progressive transition to electric vehicles.
  • Integration of climate considerations into operational planning.

These initiatives reduce long-term climate risk and support alignment with a 1.5°C pathway, while acknowledging that mining will remain energy-intensive in the near term.

4. Downstream and operational emissions

4.1 Manufacturing stage

  • The manufacturing and polishing of Botswanamark diamonds is carbon neutral.
  • This ensures no net emissions are added at this stage of the value chain.

4.2 Botswanamark operations

  • Botswanamark's office operations run on renewable energy.
  • As a result, Scope 2 emissions are avoided.
  • Operational climate impact is minimal relative to the value chain.
5. SMART climate action targets (non-emissions)

In line with [2.1.2 b], the following SMART, non-emissions targets have been established.

Target 1 - Measurement and transparency

  • Specific: Quantify annual upstream Scope 3 emissions associated with diamond sourcing.
  • Measurable: Annual calculation based on carats sold.
  • Achievable: Using established carbon intensity benchmarks.
  • Relevant: Enables informed climate action.
  • Time-bound: Annually from 2025.

Target 2 - Mining-stage offsetting

  • Specific: Offset the estimated mining-related carbon footprint using Zamazama ovens in Botswana.
  • Measurable: Offsets equivalent to calculated Scope 3 footprint.
  • Achievable: Existing offset mechanism in place.
  • Relevant: Addresses the most material climate impact.
  • Time-bound: Annually from 2025.

Target 3 - Support supplier transition

  • Specific: Engage Debswana annually on progress toward its 2030 carbon-neutral ambition.
  • Measurable: At least one documented engagement per year.
  • Achievable: Embedded in supplier relationship management.
  • Relevant: Supports upstream decarbonisation.
  • Time-bound: Annually until 2030.

Target 4 - Maintain low-impact downstream operations

  • Specific: Maintain carbon-neutral manufacturing and renewable-powered offices.
  • Measurable: Annual confirmation through supplier documentation and energy sourcing records.
  • Achievable: Already in place.
  • Relevant: Prevents downstream emissions growth.
  • Time-bound: Ongoing.

Target 5 - Climate governance and capability

  • Specific: Integrate climate considerations into sourcing, ESG, and compliance processes.
  • Measurable: Climate included in 100% of supplier reviews.
  • Achievable: Leveraging existing frameworks.
  • Relevant: Ensures long-term alignment with 1.5°C ambition.
  • Time-bound: By 2026.
6. Resource allocation for implementation

Human resources

  • Senior management oversight of climate strategy.
  • Designated ESG/compliance responsibility.
  • Use of external expertise where needed.

Technical resources

  • Carbon footprint calculation methodologies.
  • Supplier data, certifications, and transition plans.
  • Monitoring of offset performance (Zamazama ovens).

Financial and material resources

Budget allocation for:

  • Local carbon offset initiatives.
  • Supplier engagement.
  • Training and reporting.

No requirement for capital-intensive infrastructure investment at brand level.

7. Stakeholder engagement and collaboration

(Compliance with [2.1.2 d])

7.1 Stakeholders involved

  • Debswana (mining partner).
  • Offset project partners (Zamazama ovens).
  • Manufacturing partner (Dharmanandan Diamonds).
  • Employees and management.
  • Industry bodies and customers.

7.2 Engagement actions

Botswanamark will:

  • Engage Debswana on climate transition progress and operational challenges.
  • Work with local offset partners to ensure credible and impactful CO2 offsets.
  • Maintain certification-based engagement with manufacturing partners.
  • Communicate climate actions transparently to customers and stakeholders.

7.3 Reflection of stakeholder input

Stakeholder feedback related to:

  • Offset integrity.
  • Climate risks.
  • Transition opportunities.

will be used to:

  • Refine climate actions.
  • Adjust offset strategies.
  • Update governance processes.

This ensures the plan remains responsive and adaptive.

8. Monitoring, review, and continuous improvement

Annual review of:

  • Scope 3 calculations.
  • Offset effectiveness.
  • Supplier transition progress.

Updates are integrated into ESG and due diligence documentation, with ongoing alignment to evolving climate best practice.

9. Summary compliance statement

This Climate Action Plan demonstrates that Botswanamark Diamonds:

  • Supports the 1.5°C global ambition.
  • Quantifies and addresses its most material climate impacts.
  • Offsets unavoidable mining emissions through local, Botswana-based initiatives.
  • Supports supplier-led decarbonisation, including Debswana's 2030 carbon-neutral target.
  • Sets SMART, non-emissions targets in line with [2.1.2 b].
  • Involves stakeholders and reflects their input in line with [2.1.2 d].
