Since the mid-1800s, humans have contributed to the release of carbon dioxide and other greenhouse gases into the air, primarily (but not only) through our use of energy and fossil-fuels.. This causes global temperatures to rise, resulting in long-term changes to the climate. Our remaining global carbon budgets are limited and international scientific understanding is clear that urgent transitions are required to de-carbonise and also to adapt to the changing climate. IEMA has recognised this urgency and in 2019 declared a climate and environmental emergency. Climate change and securing transitional change is a leading and critical work agenda for many IEMA members.
