Catalysis is essential for the development of a sustainable world and is a key technology in achieving sustainability goals in a broad range of sectors, products, and processes. The nature of catalysis is such that these three characteristics of catalysis have remained and will remain a focus in all catalysis-related research and development activities towards sustainability. The impact on the sustainability of specific societal and industrial needs and the related products and processes is generic. In many areas, and especially for the reduction of waste and energy uses, the legislation will be a major driver, although difficult to predict.
