In a joint statement 'Achieving greater open access in physics', the societies detail how they have long embraced open science and OA to research results. Their proactive engagement, such as the launch of high-quality OA journals, switching hybrid journals to full OA and establishing transformative agreements, has contributed to an average annual growth in OA physics articles of more than 25%, compared with an overall average annual growth in physics articles of around 2%.
