These technology preferences help sustainability professionals understand how the technical aspects of how solar systems work are evolving to deliver greater environmental benefits.

The report examines how renewable energy projects are being financed, analysing the balance between capital expenditure and various financing approaches. This information is particularly valuable for sustainability professionals seeking to understand how financial models are supporting or hindering environmental progress.

Thanawalla also mentioned, “Financial accessibility remains a key enabler of corporate sustainability initiatives.” These insights help environmental managers develop appropriate business cases for solar adoption, with clear understanding of available project funding options to support sustainability goals.

The report includes analysis of how incentive mechanisms like Small-scale Technology Certificates (STCs) are supporting Australia’s sustainability transition. Rankings of top STC traders by volume and market share provide context for understanding how effectively these policy instruments are driving environmental outcomes, which is regularly assessed by the Grattan Institute in their energy transition analyses.

The industry survey provides insights into the installation methodologies and operational approaches that installers use. This information helps sustainability professionals understand how installation processes are being optimised to reduce waste and improve system performance.

These operational insights are particularly valuable for organizations developing sustainable procurement guidelines or evaluating potential solar partners based on their environmental practices.

The 2024 Yearly Report features an awards section recognizing sustainability excellence across various categories. These awards highlight exemplary companies that are setting benchmarks for environmental performance in the Australian solar market.

The 2024 Yearly Solar Installation Report provides environmental managers and sustainability professionals with comprehensive, data-driven insights into Australia’s solar market and its environmental impact. The detailed installation metrics, regional analyses, and industry perspectives collectively document the nation’s progress toward a more sustainable energy system.

Embedding environmental stewardship into IT governance frameworks

Embedding environmental stewardship into IT governance frameworks

Integrating environmental stewardship into IT governance frameworks has become essential as businesses increasingly prioritise sustainability. IT operations contribute significantly to carbon emissions, energy consumption and electronic waste (e-waste). Organisations that embed environmental responsibility into their IT governance can reduce their ecological footprint, improve operational efficiency and strengthen their brand reputation.

Erica Smith, chief alliance officer and environmental, social and governance lead, Blue Connections IT, said, “Environmental stewardship supports financial performance, risk mitigation and brand differentiation. With rising energy costs, increased consumer demand for sustainable products and services, and growing pressure from investors and regulators, companies can no longer afford to overlook their environmental responsibilities.

“Poor sustainability practices in IT can lead to high operational costs, supply chain risks and reputational damage. Conversely, a proactive approach improves efficiency, attracts environmentally conscious customers and helps future-proof businesses against evolving policy and regulatory changes.

“Integrating environmental responsibility into IT governance integrates sustainability initiatives into decision-making systematically. Organisations can reduce waste, lower energy consumption and extend the lifecycle of technology assets while positioning themselves as responsible leaders in an increasingly climate-aware market.”

There are four key areas that present opportunities to embed environmental stewardship into IT governance frameworks.

1. Device lifecycle management

A structured approach to managing the lifecycle of IT assets ensures devices are deployed efficiently, maintained properly and retired responsibly at the end of their useful life. Embracing a circular economy model, where equipment is refurbished, reused or ethically recycled, can significantly reduce e-waste and resource use. Companies that adopt this approach lower their environmental impact and unlock financial value by extending the lifecycle of IT assets.

Smith said, “Effective asset recovery strategies further support sustainability efforts. Integrating secure data erasure and refurbishment into IT governance policies lets businesses repurpose functional devices within the organisation or resell them to external buyers. Responsible e-waste recycling also supports companies to process materials ethically in instances where resale is not viable, reducing landfill contributions and preventing environmental contamination. The adoption of industry-certified data sanitisation methods also safeguards compliance with security and privacy regulations.”

2. Sustainable procurement

IT governance frameworks should prioritise the selection of technology vendors and partners committed to sustainable manufacturing, responsible sourcing and energy-efficient product design. This includes favouring IT hardware with a high percentage of post-consumer recycled materials and using minimal packaging. Additionally, employing Device-as-a-Service (DaaS) models optimises IT asset utilisation while reducing upfront investment and unnecessary hardware purchases.

Partnerships with sustainability-driven IT service providers can further enhance an organisation’s environmental impact. Working with partners that offer end-to-end IT asset management solutions, encompassing secure device deployment, certified data sanitisation and ethical recycling, simplifies the process of aligning IT operations with sustainability goals. Companies that prioritise environmental stewardship in their IT governance framework gain a competitive advantage by demonstrating their commitment to responsible business practices.

3. Energy consumption

Data centres, cloud services and enterprise networks require substantial energy resources, making green IT practices essential. IT governance frameworks should include policies to reduce consumption by optimising server efficiency, reducing redundant infrastructure and using renewable energy sources. Cloud providers with strong sustainability credentials can support carbon reduction initiatives, while virtualisation strategies can consolidate workloads and improve overall energy efficiency.

4. Employee engagement

Educating staff on sustainable IT practices, such as energy-efficient device usage and responsible e-waste disposal, creates a culture of accountability. Organisations that implement green workplace initiatives, such as responsible end-of-life disposal programs, reinforce their commitment to sustainability at all levels.

“IT governance must also align with corporate environmental, social and governance commitments. Companies can contribute to broader sustainability objectives by embedding environmental stewardship into IT policies, such as net-zero emissions targets and responsible supply chain management. Clear reporting mechanisms and regular sustainability audits aid transparency, letting businesses track their progress and demonstrate accountability to stakeholders,” Smith said.

Government regulations and evolving industry standards are increasingly shaping the sustainability expectations for organisations. Aligning IT governance frameworks with best practices for environmental stewardship keeps companies ahead of regulatory requirements. Proactive adoption of sustainable IT practices positions businesses as industry leaders in environmental responsibility.

Smith said, “Integrating environmental stewardship into IT governance frameworks is not just about meeting compliance obligations; it’s about futureproofing company operations and prioritising the broader environment. Taking a proactive approach to sustainability lets organisations drive efficiency, reduce long-term costs and contribute to a healthier planet. Businesses that lead in sustainable IT governance will be well-positioned for long-term success as environmental concerns continue to shape consumer and corporate priorities.”
