Absolute CO2 emissions were broadly in line with the previous year at 2,653 kt (2019: 2,619 kt), with similar quantities of ore processed. CO2 per unit of ore processed in 2020 also remained constant at 0.045 (2019: 0.045). CO2 emissions per tonne of copper produced increased by 4% to 8.7 tonnes (2019: 8.4 tonnes), mainly due to lower overall copper production of 306 kt (2019: 311 kt) following a reduction in recovery rates in 2020.
Scope 1 emissions mainly relate to mining activities at Aktogay and Bozshakol and heat energy consumption in the East Region, which decreased by 8% following the closure of the Belousovsky concentrator and the lower volumes of ore mined in 2020 compared to the prior year.
Scope 2 emissions arising from the Group’s purchase of electrical energy from external suppliers increased by 3% to 2,245 kt (2019: 2,176 kt), due to the 1% increase in ore processed and the continuous operation of the Bozshakol clay plant during the year.Scope 2 emissions arising from the Group’s purchase of electrical energy from external suppliers increased by 3% to 2,245 kt (2019: 2,176 kt), due to the 1% increase in ore processed and the continuous operation of the Bozshakol clay plant during the year.

The Group’s CO2 intensity by revenue in 2020, as measured by the Carbon Disclosure Project (tonnes of CO2 per $1 million of revenue), was 3% lower than the prior year at 1,126 tonnes (2019: 1,156 tonnes), as revenues increased by 4% whilst total CO2 emissions increased by 1%.
The Group is committed to minimising the CO2 intensity of its operations as stated in its Environmental Policy. The Group HSS Committee is responsible for the monitoring of CO2 intensity.
The General Directors of the Group’s operations are responsible for implementing efficiency initiatives to minimise energy consumption at site level.
Reductions in CO2 intensity have been achieved through the transition to modern open pit mining. During 2020 the Group received further deliveries of new larger scale mining vehicles for use at Aktogay in advance of the completion of the Aktogay expansion project, which is scheduled to start production by the end of 2021. The new mining vehicles are equipped with lightweight trays which increase load carrying capacity and reduce fuel consumption and will lower the intensity of the Group’s energy consumption and CO2 emissions per unit of ore processed. In the longer term, the Group will seek to increase the use of renewable energy sources where possible.
The Government of Kazakhstan, where the majority of the Group’s assets are currently located, is committed to increasing electricity generation from renewable sources as part of its national development strategy, with a target of 10% of power generation by 2030 and 50% by 2050.
