Lethal concentration 50

the combined market share of all the parties to the concentration that are in a horizontal relationship is less than 50 %; and

- Under a new criterion introduced by the reform, if the combined market shares of two merging companies are between 20% and 50% but the increase in market shares due to the merger is small, the merger may now also be assessed under the simplified procedure.

the combined market share of all the parties to the concentration that are in a horizontal relationship is less than 50 %; and

the global nature of climate change calls for the widest possible cooperation by all countries, and their participation in an effective, cost-efficient and appropriate international response, in accordance with their common, but differentiated responsibilities and respective capabilities; the EU therefore looks forward to engaging with all Parties to the Convention in an open dialogue on what further action is required as a next step to move towards the ultimate objective of the Convention; the relevant Council formations should reinvigorate their efforts to integrate climate change objectives into their policy areas; recent scientific research and work under the IPCC indicate that it is unlikely that stabilisation of ...[+++]concentrations above 550 ppmv CO equivalent would be consistent with meeting the 2°C objective and that in order to have a reasonable chance to limit global warming to no more than 2°C, stabilisation of concentrations well below 550 ppmv CO equivalent may be needed; recent scientific research and work under the IPCC indicate that keeping this long-term temperature objective within reach will require global greenhouse gas emissions to peak within 2 decades, followed by substantial reductions in the order of at least 15% and perhaps by as much as 50% by 2050 compared to 1990 levels; in view of the global emission reductions required, global joint efforts are needed in the coming decades, in line with the common, but differentiated responsibilities and respective capabilities, including significantly enhanced aggregated reduction efforts by all economically more advanced countries.
