We know our activities use a lot of energy, and produce greenhouse gases. So we put a lot of effort into minimising our energy use and emissions, and in the last few years we have achieved some great success.

Emissions

Our Climate Change Strategy details our substantial emissions reduction targets, and we’re committed to pursuing emission reduction projects that are affordable and permanent rather than ‘once off’ abatement events.  

We are also committed to reviewing our emission reduction approach every five years from 2021 to ensure we continually monitor and improve progress towards our goal of ‘net zero’ emissions by 2050. It’s a target agreed to in Paris at the 21st Conference of the Parties in 2015, and we’re excited about our capacity to achieve it.

We know that not all of our emissions can be avoided, so we seek to protect carbon sinks, which are habitats that absorb more carbon than they produce, and we may also obtain carbon off sets to compensate for any differences between our goals and our actual emissions production. We also encourage our people to work towards our emission reduction targets.

Air Quality

It’s not just the emissions that escape into the upper atmosphere - the greenhouse gases - that we care about. Our activities also produce dust, gases emissions and noise, and we work to control and minimise those kinds of emissions too. We frequently conduct internal audits, verifications and assessments against our standards and legislation, and we have action plans in place to deal with any non-compliance.

We also support and actively engage in local “airshed” (air catchment area) forums and studies near our operations, to help reduce the 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 catchment of our Worsley operation.

Energy

We use energy, so we’re always looking for ways to reduce our energy use, to secure reliable, sustainable supply sources, and to reduce our greenhouse gas emissions wherever possible.

We work closely with our suppliers to manage energy supply challenges. In South Africa, we participate in industry-wide energy efficiency initiatives such as the National Energy Efficiency Accord to improve industrial energy efficiency and voluntarily reduce load demand in peak periods.

We also invest heavily in energy efficiency internally, and we are keen to support viable renewable energy schemes. We purchase hydro-generated electricity for TEMCO in Tasmania, Australia and for Mozal in Mozambique, while at Metalloys in South Africa we also have a co-generation facility that gets its energy from furnace off -gas.

In Australia, we extract high quality methane from our underground operations at Illawarra Metallurgical Coal, and provide it to a third party for power generation purposes. Extracting the methane makes the underground environment safer for our people, and more productive, as well as reducing our greenhouse gas emissions.

In Western Australia, we’re testing biomass as an alternate energy source for the Multi Cogeneration Facility at Worsley. We’re hoping to include biomass as a permanent addition into the operational fuel mix.
