Copenhagen, Stockholm, Vancouver, Oslo, Singapore, New York, Berlin, Helsinki, Paris and Tokyo. Those are, in order, the ten greenest cities in the world, according to the Global Green Economy Index, authored by DualCitizenLLC. The index, now in its fifth edition, ranks 80 countries and 50 cities, taking into account variables and initiatives in areas such as leadership & climate change, industrial efficiency, marketing & investment and environmental development. As always, the Nordic states dominate the top of the ranking. In particular, Sweden is the world’s greenest and most sustainable nation, followed by Norway, Finland, Switzerland and Germany.
Among the criteria on which the cities are evaluated are public transport, the average number of kilometers traveled per person on bicycle, the proportion of sustainable buildings, constructed according to energy efficiency criteria, parks (like Stockholm’s Ecoparken, which from Djurgården in the city center stretches as far as the Fjäderholmarna islands and north of the city), electric mobility and waste management.
The rise of cars powered not by gas but by a battery could threaten the future of conventional fossil fuel markets, according to Eldar Sætre, head of the Norwegian energy company Statoil. “Oil demand will peak in the 2020s, and then we will have a shrinking oil industry,” said Sætre, partly due to the spread of electric mobility. The IEA currently estimates that there are at least 1.2 million electric cars on the world’s roads, mainly in China and the United States, while global green energy output last year amounted to 153 gigawatts.
