The project “BiodiverCity” was carried out in Malmö in 2012-2014. The project aimed to increase urban biodiversity by creating new products, services and processes for greener cities. The project's goal was to create permanent demonstrations for the dissemination of innovative solutions for urban greenery.

In 1990 the City of Güssing decided to put the vision of becoming 100% fossil fuel free and energy self-sufficient into practice. About 15 years later the City generates twice the electricity demand of the city’s private households, public buildings and industries and also about 85% of the heating demand is covered. Both have been achieved via decentralized local energy production using renewable sources available in the region (especially wood, biomass and solar).

Akcansa is a cement company owned by Sabanci Holding and Heidelberg Cement Mediterranean Basin Holdings. It is the largest cement producer in Turkey. The cement industry is responsible for 5% of human based GHG emissions. 50% of these emissions arise from production processes, 40% from fuel consumption, 10% from electricity consumption and transportation. The Akcansa cement plant located in Canakkale constructed a waste heat recovery plant with 15.2 MW capacity which recovers waste heat as electrical energy.

The city of Bristol has implemented an alternative currency system designed to support Bristol’s local economy and reduce environmental footprints of long supply chains. The Bristol Pound was launched in 2012 as a voluntary system based on the citizen's commitment to support the value of living in an economically, socially and environmentally sustainable city.  It is the UK’s first citywide local currency, the first to have electronic accounts managed by a regulated financial institution and the first that can be used to pay local taxes. 

Hyllie is the largest development area in Malmö, and is planned to become the most climate smart district of the entire Öresund region, including 9,000 homes when completed. In this district, solutions will be tested that can act as role models and good examples for the rest of Malmö and for other cities.

The funding scheme of Denver's Arapahoe Protected Bike Lane project was not standard. After acquiring a certain amount of US$ from private sector donors it was decided to collect the remaining amount of US$ for project implementation using crowdfunding. This was decided as crowdfunding has proven to be a very successful way not only for financing but to raise citizen's awareness.

As a district heating network is more efficient and less air-polluting than having single oil-fired furnaces, every household in Rostock has the obligation to connect to the heating network, unless other environmentally friendly heating systems were installed. The Rostock district heating network is currently based on a combined heat and power (CHP) natural gas plant and on waste heat from a bituminous coal power plant. It will change to renewables as soon as the existing plants need to be replaced.

EcoBici, Mexico City’s bike sharing programme, was launched in 2010 to increase cycling while simultaneously reducing traffic congestion and transport related greenhouse gas emissions within the city. Bikes placed at several stations are able to be used for transportation within the city when users register and pay a small fee. 

In the first phase of EcoElétrico, in place since June 2014, a fleet of 12 shared electric vehicles and 10 charging stations, demonstrating a pilot e-mobility concept, are used by the Municipality of Curitiba. The fleet and charging stations are connected and monitored via an online mobility and energy management platform (“mobi.me”). The “mobi.me” platform continuously monitors all charging stations and vehicle movements and thus allows drawing conclusions on the impact of the new intelligent e-mobility-concept in real time. 

The City of Paris, together with the Île-de-France region, was the first major European city, which successfully deployed a public electric car-sharing program. The program started in 2011 with an initial fleet of 250 eco-friendly electric 'Bluecars'. The program today (2015) has more than 3,000 cars operating on the streets of Paris and within the whole region. There are around 860 Autolib stations where users can subscribe, pick up or drop off the cars. As well, there are 4,400 parking spaces and charging points reserved exclusively for ”Bluecars”. 

The refurbishment and raising of the former post office building in Bolzano, now used by the South Tyrol state administration, were designed in accordance with “CasaClima” requirements, an Italian energy certification for sustainable and passive buildings. This concretely demonstrates the role that local administration can assume in exemplifying the potential for energy-saving. 

Food waste is collected in Milan in special biodegradable bags and transferred to an anaerobic digestion plant which generates biogas and compost.Thanks to the high involvement of citizens, the current recycling rate of food waste in Milan is already above the EU target of 50% by 2020.
