Radiology plays a crucial role in modern healthcare, but its environmental impact is significant due to high energy consumption, resource use and medical waste. Sustainable practices in radiology are essential to mitigate these effects. Despite growing awareness of sustainability's importance, radiologists face knowledge gaps and institutional barriers that hinder implementation. A recent study published in Insights into Imaging explores radiologists’ knowledge, attitudes and practices regarding sustainability, focusing on the challenges and opportunities for advancing green radiology.
Radiologists’ Knowledge and Attitudes Toward Sustainability
While radiologists demonstrate awareness of sustainability concepts, their understanding remains moderate. A notable percentage acknowledge the relevance of sustainability in healthcare, but familiarity with workplace policies is limited. Many radiologists recognise the impact of healthcare waste and energy conservation, yet training on sustainable practices is often lacking. Institutional support for sustainability education is essential, as knowledge gaps hinder the widespread adoption of environmentally responsible practices in radiology departments.
Attitudinally, radiologists generally express positive views on integrating sustainability into healthcare. Many agree on the importance of sustainable practices in improving patient outcomes, yet a significant portion feels that sustainability is not a priority within their workplace. This misalignment between personal conviction and institutional commitment suggests that leadership and policy changes are needed to drive meaningful implementation.
Barriers to Implementing Sustainable Radiology Practices
Despite the willingness to embrace sustainability, radiologists face multiple obstacles that impede progress. Key barriers include inadequate training, limited financial support and a lack of leadership commitment. Without formal education and resources, radiologists struggle to implement energy-saving initiatives, waste reduction strategies and sustainable procurement practices.
Financial constraints further complicate the situation. Many radiologists believe that sustainability measures require significant investment, making it difficult for departments to prioritise green initiatives. Additionally, heavy workloads and staffing shortages leave little room for radiologists to focus on sustainability efforts. Overcoming these barriers requires a multi-faceted approach that includes dedicated funding, policy incentives and institutional commitment to sustainability.
Another critical factor impeding the transition towards sustainable radiology is the inconsistent adoption of best practices across institutions. While some radiology departments implement measures such as digital documentation, waste reduction and energy-efficient lighting, these practices are not consistently applied across the sector. Many radiologists report a lack of standardised guidelines and protocols, leading to disparities in sustainability efforts.
Moreover, sustainability training is not widely integrated into radiology education, leaving many professionals without the necessary knowledge to adopt environmentally friendly practices. Training programmes should address key areas such as energy conservation, eco-friendly procurement and waste management to ensure that sustainability becomes a fundamental aspect of radiological practice.

Pathways to a More Sustainable Radiology Sector
To bridge the gap between awareness and action, targeted strategies must be developed. First, radiology training programmes should incorporate sustainability education, ensuring that future practitioners are equipped with the necessary knowledge. Hospitals and clinics should also implement structured sustainability policies, providing clear guidelines and incentives for sustainable practices.
Leadership engagement is critical in driving change. Establishing sustainability committees within radiology departments can foster accountability and create momentum for policy shifts. Encouraging the use of energy-efficient imaging technologies, digital documentation and waste reduction measures can lead to long-term environmental and financial benefits. Additionally, forming partnerships with industry stakeholders to fund sustainability initiatives can alleviate financial burdens and enable the adoption of green technologies.
A key step towards sustainability is promoting the use of energy-efficient radiology equipment. Imaging technologies such as MRI and CT scanners consume vast amounts of electricity, but optimising their usage, upgrading to energy-efficient models and implementing power-saving protocols can significantly reduce their environmental footprint. Radiology departments should also consider transitioning to cloud-based Picture Archiving and Communication Systems (PACS) to minimise energy-intensive on-site data storage.
Furthermore, waste management should be a priority. Many radiology departments generate substantial waste, including imaging films, contrast agents and disposable protective equipment. Implementing robust recycling programmes and encouraging the use of reusable materials can reduce waste production. Hospitals should invest in procurement policies that favour sustainable and recyclable medical products.
Financial investments in sustainability initiatives should be framed as long-term cost-saving measures. While upfront costs may be high, energy-efficient technologies, digital workflows and waste reduction strategies can lower operational expenses over time. Governmental and institutional policies should offer financial incentives for healthcare facilities that prioritise sustainability, ensuring that funding constraints do not hinder progress.
While radiologists recognise the importance of sustainability, knowledge gaps and institutional barriers continue to hinder progress. Addressing these challenges requires a structured approach that includes education, leadership commitment and financial investment. Standardising sustainability practices across radiology departments and integrating training into radiology education will ensure the widespread adoption of eco-friendly measures.
By fostering a culture of sustainability within radiology, healthcare institutions can reduce their environmental impact while ensuring high-quality patient care. The transition to green radiology is both necessary and achievable with the right policies, resources and collective effort. Institutions must prioritise sustainability at all levels, from leadership decisions to daily operational practices, to create a healthcare system that balances technological advancement with environmental responsibility.
