Generally, it is appropriate to increase the contributivity of the system and its transparency, ensuring a level of sufficiency for those households with more limited resources. Also, establishing automatic adjustment mechanisms would help stabilise the system, adapting it to demographic and economic changes. Indeed, several EU countries (such as Germany, Sweden and Italy) have already established a link between the level of benefits or retirement age and life expectancy. Combating climate change and smoothing the transition to a more sustainable economy are another of the fundamental challenges we face. Fiscal policy should take the lead in attaining objectives in this field, both to deter the most environmentally harmful activities, through an internationally harmonised tax system, and to foment the public and private investment needed to develop cleaner technologies and alleviate the social costs of the transition. As to inequality, we began the current crisis with a higher level than was the case at the end of the previous upturn, and everything suggests that this crisis will entail a further increase. The employment protection and income support measures approved should contribute to lessening the vulnerability of the households most affected. Also, many of the reforms intended to improve productivity or lower unemployment and job insecurity are vital for  7  reducing inequalities. The minimum life income scheme could, in coordination with regional government arrangements, contribute to alleviating extreme poverty. In this connection it will be important, as provided for in the scheme’s founding legislation, to assess its application on an ongoing basis.
