Apart from these smaller towns, many cities have specified targets, to reach CO2 or energy neutrality somewhere in the near future.
Back in 1996 Växjö , Sweden, already committed to become a fossil fuel free city. However the claim is in fossil fuels, in practice the result is measured in "emissions", and mainly CO2. So far 30 pct reduction compared with 1993 has been established, by 2010 it should be 50 pct and in 2025: 70 pct.
Another example from Sweden is Kristianstad (75.000 people): In 1999 the executive committee of Kristianstad municipality unanimous decided to declare its will to become a Fossil Fuel Free Municipality. Primarily by the change for renewable energy sources, not so much by reduction programmes. Reduction in 2010 should be (measured by fossil fuels) of 50.000 tonnes, representing 10 % of CO2 emissions. A targeted date could not be found in the documents.
In the Netherlands many cities have Carbon neutral or energy neutral strategies in mind, and the initiatives of three cities were combined in a Carbon neutral pilot programme. This programme investigated the potential targets, strategies, and definitions, To predict achievable dates when CO2 neutrality could be established. Several cities have committed to the strategies, and are building up activities for implementation: Heerhugowaard has a "roadmap, to lead to energy neutrality in 2030, Tilburg implements activities to become climate neutral in 2045, and Apeldoorn energy neutral in 2020 (only for the built environment).
Other cities are also willing to become neutral. It's this program that led to discussion on systems, definitions and targets, the basis for this paper.
Another example comes from Masdar, Abu Dhabi [x]. This is not an existing city, but a entire new one, to be constructed the coming years. The city development has adopted the World Wildlife Fund's principles, named 'One Planet Living principles ' [x]. These include overall sustainable goals, but for energy its defined as: Zero Carbon: Achieve NO? net CO2 emissions from One Planet Living developments, (mainly buildings and infrastructure) and for transport its defined as to 'achieve major reduction of CO2 emissions from transport '.
A last example is a new city, or suburb called Dongtan, near Shanghai, PRChina. Which has maybe the most far reaching targets for new developed areas: not only 0-energy, but also a ecological footprint that completely balances nature's supply and human demand, combined with hydrogen based transport. If its realised that way, is to see, but at least the start is promising.
Kalmar region
One level up, we come to regions. And the example here is the Kalmar region, in Sweden again. By 2030, Kalmar County intends to become a fossil fuel free region. And so far this limited round of exploring initiatives, this region shows to have the most concrete and detailed plan and targets set.
There are 3 main targets: 1 energy and the environment as growth factors; 2 becoming a fossil
fuel free region by 2030; and 3 decoupling economic growth from increased fossil fuel usage. Regarding the second target, the following details are provided: By 2010, the county will decrease its emission of greenhouse gases by 15 percent compared to the amount emitted in 1990. Carbon dioxide emissions attributable to transport shall also decrease by 20 percent compared to the amount emitted in 1995.
Furthermore, all automobiles purchased or leased by the public sector shall be eco-cars.
By 2020, all buildings will be heated by renewable energy sources. The county's production of renewable electricity shall equal or exceed its electricity consumption. All transports funded by taxpayer money will be made in eco-cars or using fuel from renewable energy sources. By 2030, there will no longer be net carbon dioxide emissions from burning fossil fuels in Kalmar County.
Although very challenging targets are included, in the end also in this case result is measured in (net) CO2 emissions.

Of course there are many more examples of cities achieving interesting results, but not having a direct target or definition available. In the C40 programme, the Clinton Climate initiative for cities, many examples are available [x]. Of which Freiburg in Germany maybe has the most interesting results in implementation so far. [x]. There is also the Solar city programme, which mainly focuses at new extensions to the cities.[x] Some more are listed in the references.
Overall sustainability is of course the ultimate target, ( as Malmo in Sweden and Curitiba in Brasil are good examples) But for this paper the focus is on those cases that have targets and definitions set for carbon related or energy results.
