Climate change is an ever-increasing threat that is having significant detrimental effects on the planet and people’s health and well-being. This article explores these effects and examines the environmental impact of different types of inhalers, demonstrating the vast difference between certain types. It also discusses how children’s nurses can implement inhaler changes in children and young people effectively, using change management theory and recognised change tools as a guide. With reference to the latest research and studies, the author demonstrates how making inhaler changes can significantly reduce their impact on the environment, thereby protecting the lives of children today and future generations.
