■卫生系统对气候变化采取行动具有双重必要性。首先,他们必须发展适应气候变化的卫生服务,以应对气候变化对健康的直接和间接影响。第二,他们必须减少自己的碳足迹,因为卫生系统是全球温室气体排放的重要贡献者。
■进行了环境扩展的多区域投入产出分析,纳入澳大利亚的国民账户数据和2019-20财政年度WAHealth的年度支出数据。支出数据被归类为344个经济部门之一,并按购买商品或服务的提供者的位置分类。
■WAHealth贡献了WA总碳足迹的8%,受化学品支出(占总额的23.8%)推动,运输(占总数的20.2%),和电力供应(占总数的19.7%)。这3个部门占西澳健康碳足迹的63.7%,但仅占其总支出的10.8%。
减少西澳大利亚州与卫生服务相关的排放将需要一种整体方法,该方法利用碳足迹见解并将其纳入所有卫生计划的组织决策中。运输和化学品行业的高碳强度支持先前的研究,呼吁减少不必要的病理测试,并通过可持续的远程医疗模式过渡到非紧急医疗服务。WA的大小和位置的影响带来了挑战,主要是不可再生能源的供应,以及对其他州运输和供应链的依赖,大大增加了排放。

UNASSIGNED: Health systems have a dual imperative to take action on climate change. First, they must develop climate resilient health services in response to the direct and indirect impacts of climate change on health. Second, they must reduce their own carbon footprint since health systems are a significant contributor to global greenhouse gas emissions.
UNASSIGNED: An environmentally-extended multi-region input-output analysis was carried out, incorporating National Accounts data for Australia and annual expenditure data from WA Health for financial year 2019-20. Expenditure data were categorised to one of 344 economic sectors and by location of the provider of goods or services purchased.
UNASSIGNED: WA Health contributes 8% of WA\'s total carbon footprint, driven by expenditure on chemicals (23.8% of total), transport (20.2% of total), and electricity supply (19.7% of total). These 3 sectors represent 63.7% of WA Health\'s carbon footprint, but only 10.8% of its total expenditure.
UNASSIGNED: Reducing emissions related to health service provision in WA will require a holistic approach that leverages carbon footprinting insights and integrates them into organisational decision-making across all health programs. The high carbon-intensity of the transport and chemicals sectors supports previous research calling for a reduction in unnecessary pathology testing and the transition to delivery of non-urgent health care via sustainable models of telehealth. The impact of WA\'s size and location presents challenges, with a predominantly non-renewable energy supply and reliance on transport and supply chains from other states adding significantly to emissions.
