Oslo (Norway)...

According to ehcitychallenge.org the main aim is to become the leading city in sustainability across the world by 2020. The concept is to have a city that runs on 100% renewable energy by having only environmentally friendly buildings and public spaces as well as to be operating high quality mass transportation and recycling systems.

 They’ve also installed a system where each car on the road will have to pay toll to use the freeways. This is similar to the new “e-toll” system that will be used in Gauteng and Cape Town. The city of Oslo had a trial run in 2006 where it indicated that traffic had reduced by 20-25%, and this rate has been maintained even with the population drastically increasing. The system is only working between 06:30-18:00 every weekday. If the e-toll system in south-Africa can be initiated correctly, drastic changes in traffic will be seen and this will also result 

in lower usages off fossil fuels.

 The oslo climate and energy fund was created to help aid the transition from fossil fuels to renewable energy. By doing so, the government has started awarding any climate and energy efficiency projects. And in 2011, 9Billion US Dollars was awarded for these projects.

 The latest strategy was to create shore based electric power for cruise ships. This is done to reduce the pollution created by all the cruise ships entering its harbor every day. Results shows a reduction of 3000 tons of emissions per year.

 Solar Farms are seen all over the World and is soon to be a part of South Africa's Mass Renewable System.
