In 1976, he founded The Prince’s Trust, an organization that supports young people in developing skills, finding jobs, and launching businesses. The trust has helped over a million young people across the UK, particularly those from disadvantaged backgrounds, by offering them a chance to succeed and transform their lives. This passion for empowering youth has set a new standard for royal charity in Europe. King Charles’s environmental advocacy has been particularly remarkable. He was a prominent environmentalist long before it became mainstream, and he continues to champion conservation, climate change awareness, and sustainable farming practices.

His charity, the Prince's Foundation, focuses on sustainable communities, arts, and heritage conservation, emphasizing the importance of preserving traditions and fostering environmental responsibility. This foundation aligns closely with King Charles's deep-rooted belief in sustainability and protection of natural resources. Apart from his work with The Prince’s Trust and the Prince’s Foundation, King Charles has been associated with numerous other charities, spanning diverse causes. He is a patron of the British Red Cross, supporting their humanitarian efforts worldwide, and he also backs healthcare charities such as the Royal National Orthopaedic Hospital. His patronage extends to artistic and cultural charities, like the Royal Opera House and the Royal Shakespeare Company, highlighting his appreciation for British cultural heritage.
