Technology/infrastructure: Historic investments in technology and essential infrastructure have long been linked to path dependency or technology lock-in (Unruh, 2000,2002), which can dramatically shape a city's path toward green growth. These sunk investments may offer short-term cost advantages that prevent alternative technologies to effectively compete on price. Heavily industrial cities may find that pollution and escalating energy demand top the list of issues to be addressed through a green growth strategy, while cities dominated by a service-based economy, like tourism, may pursue greening strategies that enhance recreational amenities. Cities with low per capita income or high corporate tax rates may find it difficult to finance green growth.
