Research, Resources and Reports


“The carbon footprint of hospital diagnostic imaging in Australia”

McAlister S, McGain F, Petersen M, Story D, Charlesworth K, Ison G, Barratt A. The carbon footprint of hospital diagnostic imaging in Australia. The Lancet Regional Health-Western Pacific. 2022 Jul 1;24:100459.

This research measured the carbon footprint of five common imaging modalities: chest X-ray (CXR), mobile chest X-ray (MCXR), computerised tomography (CT), magnetic resonance imaging (MRI) and ultrasound (US). The findings call for a reduction in unnecessary imaging, scanners to be turned off, and ensuring high utilisation rates of scanners.

“Ventilation strategies and design impacts on indoor airborne transmission: A review” 

Izadyar N, Miller W. Ventilation strategies and design impacts on indoor airborne transmission: A review. Building and Environment. 2022 May 6:109158.

This literature review tracks the number of scientific papers on ventilation strategies and indoor transmission against the four most recent pandemics, and reviews the ventilation strategies and designs addressed for both clinical and non-clinical environments.

“The origins of food supplied to an Australian public hospital” 

Faulkner K, Gilbertson H, Porter J, Collins J. The origins of food supplied to an Australian public hospital. Frontiers in Nutrition. 2022;9.

This research quantified the local food purchased by a Victorian public hospital. It identified that 3% of the budget was spent on entirely ‘local’ Victorian grown food. It calls for a sharing of food origin data, a clear definition of ‘local’ food and further understanding of Victorian food growing industries. 

“Effectiveness of strategies to decrease animal sourced protein and/or increase plant sourced protein in foodservice settings: a systematic literature review”

Stiles G, Collins J, Beck K. Effectiveness of strategies to decrease animal sourced protein and/or increase plant sourced protein in foodservice settings: a systematic literature review. Journal of the Academy of Nutrition and Dietetics. 2021 Dec 23.

This systematic review evaluated the effectiveness of strategies to decrease animal protein and/or increase plant protein in foodservice settings on uptake, satisfaction, financial, environmental, and dietary intake outcomes. The most promising strategies were menu redesign, followed by menu labelling and service redesign. 

“Discrepancy between procurement and clinical use of nitrous oxide: waste not, want not”

Seglenieks R, Wong A, Pearson F, McGain F. Discrepancy between procurement and clinical use of nitrous oxide: waste not, want not. British Journal of Anaesthesia. 2022 Jan, 128(1): E32-34. 

This correspondence article discusses the global warming effects of nitrous oxide in comparison to desflurane.


Sustainable Healthcare in Practice micro-credential

The Monash Sustainable Development Institute is developing a micro-credential on sustainable healthcare, due for release in mid-2022.

Free module on the climate crisis and population health

Health Education England has released a free module on the relationship between climate change and population health, called “All our Health: Climate Change”. It includes key evidence and resources to prevent illness, protect health and promote wellbeing. No fee or registration required – check it out here.

‘Our planet, our health’ resources from WHO

The theme of this year’s World Health Day was “Our planet, our health”. The World Health Organisation made various related resources available. Check them out here.

Global Road Map for Health Care Decarbonization

A reminder of this excellent resource, released last April by Health Care Without Harm: the first ever global roadmap for health care decarbonisation. It’s intended as a navigational tool for achieving zero emissions with climate resilience and healthy equity. Read it here.

Healthcare waste trackers 

They say “if you can’t measure it, you can’t manage it”, yet many health care facilities don’t record how waste is produced and managed. Health Care Without Harm and HECAF360 have developed six Excel-based waste tracking tools to determine how waste is produced, managed and controlled at different stages of the waste process. Download the trackers here.

Sustainable Procurement Resources 

Health Care Without Harm has guidance documents and resources available on sustainable procurement. Take a look here.

QLD Health: New website ‘Climate change and a sustainable public health system’

Queensland Health has released a new website outlining its ‘Climate Risk Strategy 2021-2026’. The website provides resources and tools for managing climate risk for healthcare facilities and their staff, to work towards achieving net zero emissions by 2050. Read more here


Partnering for Climate Resilience: A practical guide to community-based disaster planning for health care

Health Care Without Harm has released a new report, Partnering for Climate Resilience. This practical guide provides a new approach to disaster planning and climate preparedness built on a partnership between health systems and the communities they serve working together to plan for climate change.

New IPCC solutions report dropped in April

The Intergovernmental Panel on Climate Change released a new report on climate mitigation and solutions in April. Its key message was pressing: the climate crisis is advancing. The world needs to transition to a low-carbon, sustainable economy that limits emissions and helps meet the ambitions of the Paris Agreement. Check out the IPCC report and resources here.

In response, CAHA has dropped a new summary of the IPCC solutions report (given it was over 3,000 pages long!) This summary, Climate Action for a Healthy Future, lists the IPCC findings relevant to health and wellbeing. It is a resource for health stakeholders, professionals and policy-makers working at the intersection of climate change and health. Read CAHA’s summary here.
