Portuguese tax to focus urban regeneration and increase transparency of development costs

A study has evaluated the Municipal Urbanisation Tax (MUT)—a specific tax for the construction, maintenance, and reinforcement of urban infrastructure—in the city of Tomar, Portugal. The city has a new formula for the tax which is simpler and reinforces efforts to contain urban sprawl. The MUT is a one-time charge applied to new development through land subdivision (Loteamento) or individual buildings, similar to an impact fee. Other municipalities aiming to direct urban regeneration towards their brownfield sites, for example, could learn from the Portuguese experiences.

Green technology transfer promoted by emissions standards - even in absence of trade

China does not export cars to Europe, yet it has adopted the Euro emissions standard for vehicles. A recent study argues this is because international standards can encourage foreign investors to share advanced technical knowledge with companies in developing and emerging economies – thus bringing a package of environmental and economic benefits. In China’s case, its car industry is now better prepared for future trade in a global market, thanks to this strategy.
