5.8 Supplementarity relating to mechanisms under Articles 6, 12 and 17, of the Kyoto Protocol
Section 5.7 indicates that the emissions level in 2020 would have been about 26 million tonnes of CO2 equivalents higher than actual emissions in the absence of domestic policies and measures taken to mitigate climate change, or about 50 per cent of the 1990 emission level. The estimates are uncertain but could still be conservative as not all policies and measures are quantified. The estimates illustrate that the use of Kyoto mechanisms has been supplemental to domestic action.
By way of comparison, the gap between emissions and the commitment under Article 3.1 was 3.3 million tonnes/year for KP 1, and 9.2 Mt/year for KP 2. Such a gap also illustrates that it is possible to assume a more ambitious target with access to mechanisms than what could have been possible without.
