Natural capital is the world's stock of natural resources, which includes geology, soils, air, water and all living organisms. Some natural capital assets provide people with free goods and services, often called ecosystem services. All of these underpin our economy and society, and thus make human life possible.
Uneconomic growth is economic growth that reflects or creates a decline in the quality of life. The concept is used in human development theory, welfare theory, and ecological economics. It is usually attributed to ecological economist Herman Daly, though other theorists may also be credited for the incipient idea, According to Daly, "uneconomic growth occurs when increases in production come at an expense in resources and well-being that is worth more than the items made." The cost, or decline in well-being, associated with extended economic growth is argued to arise as a result of "the social and environmental sacrifices made necessary by that growing encroachment on the eco-system."
Ecological economics, bioeconomics, ecolonomy, eco-economics, or ecol-econ is both a transdisciplinary and an interdisciplinary field of academic research addressing the interdependence and coevolution of human economies and natural ecosystems, both intertemporally and spatially. By treating the economy as a subsystem of Earth's larger ecosystem, and by emphasizing the preservation of natural capital, the field of ecological economics is differentiated from environmental economics, which is the mainstream economic analysis of the environment. One survey of German economists found that ecological and environmental economics are different schools of economic thought, with ecological economists emphasizing strong sustainability and rejecting the proposition that physical (human-made) capital can substitute for natural capital.
Herman Edward Daly was an American ecological and Georgist economist and professor at the School of Public Policy of University of Maryland, College Park in the United States, best known for his time as a senior economist at the World Bank from 1988 to 1994. In 1996, he was awarded the Right Livelihood Award for "defining a path of ecological economics that integrates the key elements of ethics, quality of life, environment and community."
A steady-state economy is an economy made up of a constant stock of physical wealth (capital) and a constant population size. In effect, such an economy does not grow in the course of time. The term usually refers to the national economy of a particular country, but it is also applicable to the economic system of a city, a region, or the entire world. Early in the history of economic thought, classical economist Adam Smith of the 18th century developed the concept of a stationary state of an economy: Smith believed that any national economy in the world would sooner or later settle in a final state of stationarity.
William Rees, FRSC, is Professor Emeritus at the University of British Columbia and former director of the School of Community and Regional Planning (SCARP) at UBC.
Robert Costanza is an American/Australian ecological economist and Professor at the UCL Institute for Global Prosperity, University College London. He is a Fellow of the Academy of the Social Sciences in Australia and a Full Member of the Club of Rome.
Nicholas Georgescu-Roegen was a Romanian mathematician, statistician and economist. He is best known today for his 1971 magnum opus The Entropy Law and the Economic Process, in which he argued that all natural resources are irreversibly degraded when put to use in economic activity. A progenitor and a paradigm founder in economics, Georgescu-Roegen's work was decisive for the establishing of ecological economics as an independent academic sub-discipline in economics.
Mathis Wackernagel is a Swiss-born sustainability advocate. He is President of Global Footprint Network, an international sustainability think tank with offices in Oakland, California, and Geneva, Switzerland. The think-tank is a non-profit that focuses on developing and promoting metrics for sustainability.
Sustainability metrics and indices are measures of sustainability, and attempt to quantify beyond the generic concept. Though there are disagreements among those from different disciplines, these disciplines and international organizations have each offered measures or indicators of how to measure the concept.
Degrowth or post-growth economics is an academic and social movement critical of the concept of growth in gross domestic product as a measure of human and economic development. Degrowth theory is based on ideas and research from a multitude of disciplines such as economics, economic anthropology, ecological economics, environmental sciences and development studies. It argues that the unitary focus of modern capitalism on growth, in terms of monetary value of aggregate goods and services, causes widespread ecological damage and is not necessary for the further increase of human living standards. Degrowth theory has been met with both academic acclaim and considerable criticism.

Sustainability is a social goal for people to co-exist on Earth over a long time. Specific definitions of this term are disputed and have varied with literature, context, and time. Experts often describe sustainability as having three dimensions : environmental, economic, and social, and many publications emphasize the environmental dimension. In everyday use, sustainability often focuses on countering major environmental problems, including climate change, loss of biodiversity, loss of ecosystem services, land degradation, and air and water pollution. The idea of sustainability can guide decisions at the global, national, and individual levels. A related concept is sustainable development, and the terms are often used to mean the same thing. UNESCO distinguishes the two like this: "Sustainability is often thought of as a long-term goal, while sustainable development refers to the many processes and pathways to achieve it."
Mohan Munasinghe is a Sri Lankan physicist, engineer and economist with a focus on energy, water resources, sustainable development and climate change. He was the 2021 Blue Planet Prize Laureate, and Vice-Chair of the Intergovernmental Panel on Climate Change (IPCC), which shared the 2007 Nobel Peace Prize with former Vice-President of the United States Al Gore. Munasinghe is the Founder Chairman of the Munasinghe Institute for Development. He has also served as an honorary senior advisor to the government of Sri Lanka since 1980.
The Global Footprint Network was founded in 2003 and is an independent think tank originally based in the United States, Belgium and Switzerland. It was established as a charitable not-for-profit organization in each of those three countries. Its aim is to develop and promote tools for advancing sustainability, including the ecological footprint and biocapacity, which measure the amount of resources we use and how much we have. These tools aim at bringing ecological limits to the center of decision-making.
In economic and environmental fields, decoupling refers to an economy that would be able to grow without corresponding increases in environmental pressure. In many economies, increasing production (GDP) raises pressure on the environment. An economy that would be able to sustain economic growth while reducing the amount of resources such as water or fossil fuels used and delink environmental deterioration at the same time would be said to be decoupled. Environmental pressure is often measured using emissions of pollutants, and decoupling is often measured by the emission intensity of economic output. However, it is arguable that emission intensity does not adequately reflect the exponential impact on the instability of ecosystems when climate tipping points are passed. During the 2023 World Economic Forum Johan Rockstrom explained that the exponential domino effect has now commenced.
Pavan Sukhdev is an Indian environmental economist whose field of studies include green economy and international finance. He was the Special Adviser and Head of UNEP's Green Economy Initiative, a major UN project suite to demonstrate that greening of economies is not a burden on growth but rather a new engine for growing wealth, increasing decent employment, and reducing persistent poverty. Pavan was also the Study Leader for the ground breaking TEEB study commissioned by G8+5 and hosted by UNEP. Under his leadership, TEEB sized the global problem of biodiversity loss and ecosystem degradation in economic and human welfare terms, and proposed solutions targeted at policy-makers, administrators, businesses and citizens. TEEB presented its widely acclaimed Final Report suite at the UN meeting by Convention on Biological Diversity (CBD) in Nagoya, Japan.
Post-growth is a stance on economic growth concerning the limits-to-growth dilemma — recognition that, on a planet of finite material resources, extractive economies and populations cannot grow infinitely. The term "post-growth" acknowledges that economic growth can generate beneficial effects up to a point, but beyond that point it is necessary to look for other indicators and techniques to increase human wellbeing.
The Mesoamerican Society for Ecological Economics (SMEE) is a regional chapter of the International Society for Ecological Economics (ISEE). After its foundation in 2008 at Guatemala City, the organization has already celebrated its first International Conference in 2010 at Mexico City and will carry out the second International Conference, EcoEco Alternatives, between March 4 and 8 2014 at the main campus of the University of Costa Rica.
The Indian Society for Ecological Economics (INSEE) was founded in 1998 and registered as a Society under the Societies Registration Act in January 1999. Headquartered in New Delhi, this is a regional society affiliated to the International Society for Ecological Economics (ISEE). The society publishes a bi-annual, open access peer-reviewed journal Ecology, Economy and Society–The INSEE Journal, books and other materials, and holds periodic meetings and conferences to facilitate a voice for ecological economists.
