The environmental impact of large-scale economic activities has gained significant attention in recent decades, urging governments, international organizations, and other stakeholders to adopt regulations to minimize their ecological and societal footprints. This is equally important in the space sector, where both government and private entities are pressured to justify their operations and lessen negative impacts, while complying with both national and international standards and anticipating future costs and taxes associated with environmental harm. The space industry has long recognized the potential damages of irresponsible activities, notably in areas like telecommunications and space debris in low-Earth orbits. However, space operations, particularly Earth observation from space, are vital for tracking, understanding, and mitigating both human-induced and natural environmental changes. This includes monitoring atmospheric greenhouse gases, changes in water bodies and ice caps, and detecting environmental pollutants, which are essential for informed decision-making and preventing detrimental practices. A nine-day course offered by space sector professionals and academics will cover how large organizations address their environmental duties, including Life Cycle Assessment of their products and innovations in propellants and recycling. It also explores Earth observation technologies’ role in agriculture, emergency response, and regulatory enforcement, alongside current and forthcoming political and legal frameworks to promote sustainable practices in the space sector.
