In order to enable transition from the old development mode into a new low-carbon approach, the National Development and Reform Commission (NDRC) started a low-carbon pilot program in 2010. Hangzhou has been selected as one of the pilot cities to implement a “low-carbon city pilot project”.
The pioneering shared plan to tackle climate change “Manchester: a Certain Future (MACF)” is an integrated plan that defines the main actions by which Manchester will tackle climate change until 2020.
The Marmaray railway public transportation system was opened in 2013 in Istanbul. Transportation has been a major problem for Istanbul for many years, especially transportation between the two sides of the city - Asia and Europe - has been a real challenge. Before Marmaray has been implemented the two sides have been connected only by highways (2 Bosporus bridges) and sea transit ferries. The high-tech construction methods used for the Marmaray project helped creating smart solutions for specific challenges in cities.
METU (the Middle East Technical University) is located in Ankara, the capital city of Turkey. It includes a technopark for R&D companies. The maintaining of open green areas in the technopark and the university is an important issue, which is however costly. In order to decrease the irrigation costs and increase water efficiency, a water treatment facility was constructed at the campus. The operation of this system helps to treat wastewater and to reuse it for irrigation. This system saves 150,000 € annually for the technopark.
Driven by the growing dependence on oil for energy and by the huge environmental impact of the use of fossil fuels, Portugal is investing in new sustainable energy models for mobility that aim to improve quality of life in cities.
