By 2050, global population will reach approximately 9 billion and 75% of us will be living in cities. Many global environmental systems are already under severe stress, with impacts on water, biodiversity, climate change, and nutrient cycles, amongst others. Engineers face huge challenges in planning and designing infrastructure for our growing cities, working within the carrying capacity of the planet.The objective of the research is to understand how the growth of cities impacts global environmental systems. The goal is to move beyond understanding the environmental impacts (footprints) of individual cities, to quantifying the aggregate impacts of all cities at the global scale.The method involves a novel scientific approach, composed of two main steps:i) testing and improving a mathematical model of the urban metabolism of cities;ii) scaling up the model to all cities.The research is expected to improve the scientific and engineering input into public policies that link the greening of cities with global environmental challenges. The research direction has been motivated through my work with several international organizations, including C40, OECD, UNEP, UN-Habitat, and the World Bank. It is expected to make new, original connections between the evolving science of cities and global environmental science.

到2050年，全球人口将达到约90亿，75%的人将生活在城市。许多全球环境系统已经处于严重压力之下，对水、生物多样性、气候变化和营养循环等产生了影响。工程师们在为我们不断发展的城市规划和设计基础设施方面面临着巨大的挑战，在地球的承载能力范围内工作。研究的目的是了解城市的发展如何影响全球环境系统。我们的目标是超越对环境影响的理解该方法采用了一种新的科学方法，包括两个主要步骤：i）测试和改进城市新陈代谢的数学模型; ii）第二阶段将该模型推广到所有城市。该研究有望改善将绿化与公共政策联系起来的科学和工程投入。面临全球环境挑战的城市。研究方向的动机是通过我与几个国际组织的合作，包括C40，经合组织，环境署，人居署和世界银行。它有望在不断发展的城市科学和全球环境科学之间建立新的、原创的联系。
