Without new policies, goals will not be achieved
Although the 1992 Rio Conference resulted in many activities aimed at sustainable development, trends have not been reversed in key areas and will probably continue without additional action.
The world has seen improvements in welfare, a reduction in absolute poverty, as well as in local environmental problems. However, in important spheres – including food, land and biodiversity and energy and climate – policies have not led to a reversal of historical, unsustainable trends. Up to 2050, it is expected that without a major policy shift the access to food and modern energy will increase, but not enough to provide full access for all. Furthermore, biodiversity loss will continue, greenhouse gas emissions will increase and air pollution levels will remain high.
