Hausaufgabe =head3 Zusammenfassung Canada tries to meet the terms of the Kyoto Procotol, but it needs help to do so successfully: while the Kyoto Procotol demands a cut of emissions to 6 % below 1990-levels by 2012, in 2003, emissions were 24 % above 1990-levels. This is because of the boom of the oil and gas industry and the carbon-trading market. Not only whole countries can sign the Kyoto Protocol, but mere cities can do so, too. These local communities -- for example Montreal -- contribute greatly, too -- not only because they help to cut emissions, but also because they set a "psychological sign", indicating the willingness of the general public to help. For the Kyoto Protocol to be successful, the various problems have to be tackled at all government levels.
