This pragmatic guide has been developed based on the work of the PCRS Greener Healthcare Working Group. In 2020, the PCRS Greener Healthcare Initiative brought together respiratory healthcare professionals working in primary and secondary care setting, public health specialist, patient advocacy organisations, patient representative, policy influences, service users and decision makers as well as representatives from the pharmaceutical industry. This pragmatic guide brings together practical and immediately implementable strategies to enable healthcare professionals to understand and deliver greener respiratory healthcare in the primary care setting. This guide is relevant to any healthcare professional working in primary care who wishes to understand and reduce the impact of the respiratory healthcare they deliver on the environment
