Based on the analysis, mitigation measures have been grouped according to two different contributions: Unconditional contribution: A reduction of 6 per cent relative to BAU in the year 2040; equivalent to an estimated mitigation level of 2.1 million tonnes of carbon dioxide equivalent (tCO2 e) in that year. This is an unconditional target, based on domestically supported and implemented mitigation measures and policies. Conditional contribution: An additional reduction of 45 per cent relative to BAU in the year 2040; equivalent to an estimated mitigation level of 15.6 million tCO2 e in that year. This represents an additional targeted contribution, based on the provision of international support and funding.
