The greatest impacts for sustainable living by the human population of Earth may not be the individual actions, but rather the collective actions, such as:
- Carbon tax or carbon trading
- Public transport, cycling and walking infrastructure that allows members of the society to travel sustainably without sacrificing quality of life - indeed enhancing it, while also saving money.
- Urban planning regulations that encourage, rather than discourage, sustainability, allowing higher densities, encouraging alternatives such as cohousing and abandoning old principles such as setback, and the requirement
- Elimination of tariffs on renewable energy products (such as solar water heaters).
