It has become a cliché that environmental problems are substantial, and that economic growth contributes to them. A common response is stricter environmental regulation, which often inhibits growth. The result can be a trade-off between a healthy environment on the one hand and healthy growth on the other. As a consequence, opportunities for business may be constrained. However, there are some forms of development that are both environmentally and socially sustainable. They lead not to a trade-off but to an improved environment, together with development that does not draw down our environmental capital. This is what sustainable development is all.
