The latest projections by the Department of Climate Change, Energy and Water discussed by Climate Change and Energy Minister Chris Bowen on 27 November highlight the transformative impact of critical policies starting in 2025 — including the New Vehicle Efficiency Standard (NVES) and an expanded Capacity Investment Scheme (CIS). These initiatives are set to accelerate Australia’s shift to cleaner energy, transport and industry, with the NVES projected to slash 20 million tonnes of pollution by 2030 alone.

Renewables powered more than one-third of Australia’s grid over the past year. Major projects — like the 700-megawatt battery replacing Eraring’s retired coal-fired power station set to be the largest in the Southern Hemisphere, and Victoria’s 100% publicly owned solar farm and battery near Horsham — coming online can help cut climate pollution further.

Climate Councillor and energy expert Greg Bourne said: “Renewable energy has already made up about 40% of electricity in the national grid in the past 12 months. The Australian Energy Regulator, the Australian Energy Market Operator and the International Energy Agency have outlined our safest, cleanest and lowest-cost path forward: renewables from the sun and wind, backed by storage like batteries and pumped hydro.

“All of our aging and unreliable coal-fired power stations will shut down before 2040; it’s inevitable and already in motion. We need to be firming up plans to power Australia with more clean energy to power our lives around the clock, keep our communities safer, and put power back into the hands of Aussies.”

Climate Council CEO Amanda McKenzie said: “Significant progress on climate action has been made in the last two years. Australian homes and industry [are] now powered with 40% renewable power which is slashing climate pollution.

“Australia’s shift to clean energy is well underway. Just this month, Australia hit its four millionth rooftop solar installation and the federal government introduced standards to help electric vehicle owners use their car to power their homes.

“Businesses are taking note and going solar. More than 100,000 households have added a battery to their solar system. Our heavy industries are increasingly using energy from clean sources and boosting their green hydrogen capacity. Australia has more than 160,000 electric vehicles registered domestically.

“These solutions are making a tangible difference right now to slash Australia’s climate pollution. After a decade of inaction, Australia has strong momentum with Australians benefiting from renewables jobs and opportunities opening up in the regions. Renewable power backed up by batteries can provide the 24/7 power for a modern economy for 2030 and beyond.”

The Climate Council recently launched its Momentum Monitor, which tracks the progress of climate solutions in Australia’s energy, transport and manufacturing industries. Data in the Momentum Monitor will be updated quarterly.

Bee Hotels Can Help Native Pollinators Recover in the Wake of Climate-Fueled Wildfires: Study

Wild pollinator populations are declining all over the world, with increasingly severe climate change-fueled wildfires threatening their survival. These intense wildfires are also putting long-term ecosystem health and biodiversity at risk. Bee hotels are artificial nesting structures that have been specially designed to house cavity-nesting species. Often placed in backyards or gardens, they provide safe […]

ABB receives EPD status for gearless mill drive ring motor

ABB receives EPD status for gearless mill drive ring motor

ABB has gained Environmental Product Declaration (EPD) status for its Gearless Mill Drive (GMD) ring motor — technology used to drive large grinding mills in the mining industry.

An EPD is a standardised document that provides detailed information about the environmental impact of a product throughout its life cycle. Based on a comprehensive Life Cycle Assessment (LCA) study, the EPD highlights ABB’s commitment to transparency, environmental responsibility and supporting customers in making informed decisions on sustainability in their supply chains.

ABB analysed the environmental impact of a ring motor across its entire life cycle from supply chain and production to usage and end-of-life disposal. The study was conducted for a ring motor of a semi-autogenous grinding (SAG) mill with an installed power of 24 MW and was based on a reference service life of 25 years.

“Sustainability is at the core of our purpose at ABB, influencing how we operate and innovate for customers,” said Andrea Quinta, Sustainability Specialist at ABB. “By earning the Environmental Product Declaration for our ring motor, we emphasise our environmental stewardship and industry leadership for this technology. We adhered to the highest standards throughout this process, as we do in the ABB Ring Motor factory every day. This recognition highlights to the mining industry what they are bringing into their own operations when they work with ABB.”

The comprehensive LCA was conducted at ABB’s factory in Bilbao, Spain, and was externally verified and published in accordance with international standards ISO 14025 and ISO 14040/14044. It will remain valid for five years.

The ring motor, a key component of the GMD, is a drive system without any gears where the transmission of the torque between the motor and the mill is done through the magnetic field in the air gap between the motor stator and the motor rotor. It optimises grinding applications in the minerals and mining industries by enabling variable-speed operation, leading to energy and cost savings.

The full EPD for the ABB GMD Ring Motor can be viewed on EPD International.
