Emissions

Our commitment to our Climate Change Strategy and focus on emission reduction continues. We are progressing towards meeting our short-term emission reduction target, to stay below our FY15 Scope 1 emission baseline in FY21.

We are committed to reviewing and ratcheting our carbon emissions reduction approach every five years from FY21 towards net zero carbon emissions by 2050. Any remaining (residual) emissions will form the basis of our carbon offset planning to reach the net zero goal by 2050.

Our minimum performance requirements for management of our emissions are detailed in our environment standards. These requirements include:

■ Monitoring of all emission sources in accordance with applicable regulations or standards
■ Incorporating emission reduction initiatives into our business planning process
■ Maintaining ‘life of operation’ emission forecasts that are inclusive of Scope 1 and Scope 2

Emission reduction targets are included in our Business Scorecard. Performance against these targets is directly linked to all employee remuneration, including the Lead Team.

Energy

We regularly review our energy supply options to identify sustainable supplies and reduce our GHG emissions wherever possible.  Energy costs represent a significant component of operational expenditures and a disruption in energy supply could have a direct impact on our production. 

Consistent with the requirements of our environment standards, our business planning process considers energy use and identifies energy efficiency initiatives. 

We have invested in energy efficiency initiatives and continue to support viable renewable energy schemes. We purchase hydro-generated electricity for TEMCO in Australia, Cerro Matoso in Colombia and Mozal Aluminium in Mozambique.

At our Metalloys manganese smelter in South Africa we have a co-generation plant that sources its primary energy from furnace off-gas, which is both cost-efficient and reduces our demand from the national grid. At TEMCO, we operate an energy recovery unit which creates efficiency by sourcing energy from furnace off-gas. Eskom is the state-owned power provider in South Africa supplying electricity to all of our Southern African operations (via Motraco for Mozal Aluminium).

Air Quality

We continue to monitor and implement controls to minimise the potential impacts of dust, gaseous emissions and noise across our operations to remain within regulatory limits and address community concerns. We frequently conduct internal audits, verifications and assessments against our internal standards and legislation, and address potential non-compliances through action plans. 

We regularly review our approach to air emissions to ensure we continue to mitigate potential impacts and manage our performance. We continue to support and actively engage in local airshed (air catchment area) forums and studies near our operations to help reduce the potential impact on our local communities and improve ambient air quality.

Examples of our involvement include the Collie Airshed Study in the south-west of Australia, which is within the airshed of our Worsley Alumina operation.
