The document discusses the need for a transition to a more sustainable economy that limits resource depletion and environmental degradation while still allowing for economic prosperity and job growth. It outlines some key features a new sustainable economy may have, such as fewer durable goods, more services, shorter work weeks, and policies that encourage renewable energy, energy efficiency, and investments in human and natural capital over energy-intensive manufacturing. Macroeconomic solutions proposed include incorporating sustainability into indices of national income, investing in public goods, and equalizing income.
