equilibrium with basic ecological support systems". Scientists in many fields have highlighted The Limits to Growth, and economists have presented alternatives, for example a 'steady-state economy', to address concerns over the impacts of expanding human development on the planet. In 1987, the economist Edward Barbier published the study The Concept of Sustainable Economic Development, where he recognized that goals of environmental conservation and economic development are not conflicting and can be reinforcing each other. A World Bank study from 1999 concluded that based on the theory of genuine savings (defined as "traditional net savings less the value of resource depletion and environmental degradation plus the value of investment in human capital"), policymakers have many possible interventions to increase sustainability, in macroeconomics or purely environmental. Several studies have noted that efficient policies for renewable energy and pollution are compatible with increasing human welfare, eventually reaching a golden-rule steady state. A meta review in 2002 looked at environmental and economic valuations and found a "lack of concrete understanding of what “sustainability policies” might entail in practice". A study concluded in 2007 that knowledge, manufactured and human capital (health and education) has not compensated for the degradation of natural capital in many parts of the world. It has been suggested that intergenerational equity can be incorporated into a sustainable development and decision making, as has become common in economic valuations of climate economics. The 2022 IPCC Sixth Assessment Report discussed how ambitious climate change mitigation policies have created negative social and economical impacts when they are not aligned with sustainable development goals. As a result, the transition towards sustainable development mitigation policies has slowed down which is why the inclusivity and considerations of justice of these policies may weaken or support improvements on certain regions as there are other limiting factors such as poverty, food insecurity, and water scarcity that may impede the governments application of policies that aim to build a low carbon future. The World Business Council for Sustainable Development published a Vision 2050 document in 2021 to show "How business can lead the transformations the world needs". The vision states that "we envision a world in which 9+billion people can live well, within planetary boundaries, by 2050." This report was highlighted by The Guardian as "the largest concerted corporate sustainability action plan to date – include reversing the damage done to ecosystems, addressing rising greenhouse gas emissions and ensuring societies
