Petra’s value-led growth strategy is underpinned by its focus on sustainability. The Group has a significant resource base of c.226.6 million carats, which supports the potential for long-life operations.
Petra is committed to achieve net-zero GHG emissions for Scope 1 and 2 by 2050, but aspires to reach this goal by 2040. To support this long-term target, Petra has committed to a 35-40% GHG reduction of Scope 1 and 2 by 2030 off our 2019 baseline.
Our short-term strategy is to minimise overall energy usage wherever possible. Long term we aim to reduce our reliance on fossil fuel energy sources by continuously finding ways to reduce energy consumption, be more efficient, and advocating for renewable power sources in line with The Paris Agreement and the UN’s SDG on climate change. This will be crucial to our competitive position and our ability to contribute meaningfully to the future.
In addition, Petra developed an energy management plan, based on the principles of ISO 50001, in FY 2021. Accordingly, each operation has its own specific energy management policy and management plan that is updated annually. Currently, these management plans focus on efficient electricity usage. As a responsible Company, Petra continues to focus on reducing our carbon footprint and impact on climate change.
Petra discloses its climate change, forests and water security impacts impacts through CDP, a global non-profit that runs the world’s leading environmental disclosure platform. CDP drives companies and governments to reduce their greenhouse gas emissions, safeguard water resources and protect forests. Read our CDP disclosure in full here.
The Petra Climate Change Adaptation Strategy (“PCCAS”) is an important step into the future as it:
The strategic framework for Petra’s Climate Change Adaptation consists of 11 steps:
The climate change scenario analysis for each operation has now been completed. The scenarios used are RCP 8.51 and RCP 2.6, which cater for both the worst-case and best-case emissions future.
Implementation of the PCCAS will span over five years with Phases 1 and 2 completed in FY 2020. Phase 3 (completion of operational vulnerability assessments) is now underway and will be followed by Phase 4 (implementation) and Phase 5 (ongoing monitoring) thereafter.
The Climate Change Vulnerability Assessment of FY 2021 identified 80 potential impacts at an operational and corporate level. Of these, none were rated as ‘high’ vulnerabilities but 17 were rated to be of ‘moderate’ significance. The top ten vulnerabilities are listed below:
The Vulnerability Assessment process also identified a number of opportunities for Petra, with the most significant being:
In 2013, Petra started tracking Scope 1, 2 and 3 (limited) emissions at all operations and used this information as the ‘base year’ from which to calculate the Company’s carbon footprint. In FY 2016, the base year was then reset on the basis of material changes in the Company, with an intensity value of 0.20 tCO2-e/ct. Further changes in the Group structure at the end of FY 2018 necessitated a further recalculation of the base year; thus FY 2019 is now regarded as our base year.
The scope of our carbon footprint covers all of Petra’s mines, as well as our offices situated in Johannesburg and London.
The following activities are included into the carbon footprint calculation:
Petra uses the GHG Protocol on the reporting of greenhouse gas as well as IPCC Guidelines for National Greenhouse Gas Inventories of 2001 to calculate and report on our carbon footprint. This provides us with confidence that the correct information is portrayed to our stakeholders and enables us to be held accountable for the figures presented. .Read Petra’s inaugural GHG Emissions Report here.
Carbon sequestration at Petra is implemented through the maximisation of indigenous vegetated areas. According to research, each hectare of natural vegetation is responsible for the sequestration of 300kg of carbon per annum; thus, the approximate 6,981 ha of protected area under Petra’s control results in the sequestration of 2,094 tonnes CO2 per year.
In addition, Petra is participating in projects in collaboration with other major diamond producers and academic institutions that focus on the potential of carbon sequestration through mineralisation.
Petra has no significant sources of air emissions. Non-point sources of dust and particulates (i.e. environmental drop-out dust and particulate matter measures as pm10) as a result of surface activities are strictly regulated and annual results are submitted to the authorities for evaluation. Two of our operations (the Finsch and Cullinan Mines) reported dust levels above the allowable limit of 1,200 mg/m2/day, on 22 separate occasions (monitoring is done on a monthly basis). Samples of the collected dust were analysed to determine the origin. In all instances it was determined that the collected dust came from surrounding agricultural areas, adjacent lime mines or dirt roads. Therefore, no additional dust suppressing mitigation was initiated. See page 86 for detail on expected gases and other air emissions as they relate to the Company.
Petra does not produce, import or export any ozone-depleting substances.
Petra discloses its climate change, forests and water security impacts impacts through CDP, a global non-profit that runs the world’s leading environmental disclosure platform. CDP drives companies and governments to reduce their greenhouse gas emissions, safeguard water resources and protect forests. Over 13,000 companies with over 64% of global market capitalization disclosed environmental data through CDP in 2021. This is in addition to the over 1,100 cities, states and regions who disclosed, making CDP’s platform one of the richest sources of information globally on how companies and governments are driving environmental change. Read our CDP disclosure in full here.
Petra has participated in voluntary reporting to the CDP since 2013, with year-on-year improvement of disclosure scores on every report. During 2016 and 2017, Petra scored a ‘C’ (the ‘awareness’ band), which is in line with industry and region scores. In 2018 and 2019, we improved our score to ‘B’ (the ‘management’ band) and in 2020 we achieved our highest score yet: A- (‘leadership’ band), which places Petra within the top 11% of companies reporting to the CDP. This is above average for the industry and region alike.
As previously noted, the CDP questionnaire on Climate Change has been significantly revised to incorporate both the recommendations of the TCFD and improved alignment with other reporting frameworks such as the SDGs. Petra completed and submitted the questionnaires on Climate Change, Water Stewardship and Forestry in July 2021.
Petra considers that for the first time it has met all the requirements of the TCFD, which aims to develop voluntary, consistent climate-related financial risk disclosures for use by companies in providing information to the financial markets and other stakeholders. The PCCAS has been compiled with reference to the TCFD to ensure that Petra can meet these recommendations. In terms of the disclosure requirements, Petra has included the requisite information on pages 212 and 213 of its 2021 Annual Report. It should also be noted that during FY 2021 the Company completed submissions of the CDP climate change questionnaire, which has been updated to include the recommendations of the TCFD. Therefore, Petra considers that its 2020 and 2021 CDP submissions also provide all the disclosures required in relation to TCFD recommendations.
