Abstract
The Anthropocene can be read as being the era when the demand humanity makes on the biosphere's goods and services-humanity's 'ecological footprint'-vastly exceeds its ability to supply it on a sustainable basis. Because the 'ecological' gap is met by a diminution of the biosphere, the inequality is increasing. We deploy estimates of the ecological gap, global GDP and its growth rates in recent years, and the rate at which natural capital has declined, to study three questions: (1) at what rate must efficiency at which Nature's services are converted into GDP rise if the UN's Sustainable Development Goals for year 2030 are to be sustainable; (2) what would a sustainable figure for world population be if global living standard is to be maintained at an acceptably high level? (3) What living standard could we aspire to if world population was to attain the UN's near lower-end projection for 2100 of 9 billion? While we take a global perspective, the reasoning we deploy may also be applied on a smaller scale. The base year we adopt for our computations is the pre-pandemic 2019.
期刊介绍：
The primary concern of Environmental & Resource Economics (ERE) is the application of economic theory and methods to environmental issues and problems that require detailed analysis in order to improve management strategies. The contemporary environmental debate is in a constant state of flux and new or relatively unexplored topics are continually emerging. The Journal provides a forum for the further exploration of the causes, consequences and policy responses linked to these topics, across a range of spatial and temporal scales up to the global dimension. Contributions to the Journal should directly or indirectly be relevant to the policy formulation and application process. Areas of particular interest include: evaluation and development of instruments of environmental policy; cost-benefit and cost effectiveness analysis; sectoral environmental policy impact analysis; modelling and simulation; institutional arrangements; resource pricing and the valuation of environmental goods; environmental quality indicators. The editors wish to encourage a pluralistic approach to both theoretical and applied contributions. The publication of empirically based, policy-oriented research is given a high priority in the Journal in order to further critical discussion. Environmental & Resource Economics will also accept papers with an interdisciplinary approach, where this helps to improve knowledge of the real world complexities present, provided that the analysis retains links to or components of economic thinking. The Journal is required reading for economists, economic geographers and other academics, professionals and officials with a working interest in environmental matters.
