© 2015 The Institution of Chemical Engineers Sustainability has become a major focus for industrial sectors and government agencies in the global community. In particular, climate change is now seen as the most critical environmental problem of the world. Various techniques have thus been developed in the past decades to guide planners to reduce greenhouse gas emissions at various scales, ranging from plant-level combustion emissions to regional or national carbon footprints. Process integration techniques that were previously developed for energy, mass and property integration have now been extended to various emission and environmentally-constrained problems, taking into account footprint metrics that measure environmental impacts other than global warming. This paper discusses the historical evolution of the recently developed process integration techniques for various emission- and footprint-related problems, along with their contributions and limitations. Some recent applications for specific countries are also reviewed.
