Conversely, measures to combat climate change will promote sustainable development. The economist estimated that poverty reduction and the achievement of other sustainable development goals will require about $2 billion to $3 trillion a year over the next 15 years, what they called «pure fantasy.»  Estimates for the provision of safe drinking water and sanitation to the entire population of all continents are $200 billion.  The World Bank says that estimates must be made from country to country and often need to be reassessed over time.  Conservation and sustainable exploitation of oceans, seas and marine resources for sustainable development. The post-2015 development agenda was a process led by the United Nations from 2012 to 2015 to define the future global development framework that would follow the Millennium Development Goals. The SDGs were designed to meet the Millennium Development Goals (MDGs) that ended in 2015. The shortcomings and shortcomings of goal 8 of the WCO (developing a global partnership for development) have led to the identification of a problematic «donor-recipient» relationship.  Instead, the new SDGs are in favour of collective action by all countries.  The 2030 agenda consists of four sections: (i) a political declaration (ii) a set of 17 Sustainable Development Goals and 169 objectives (based on the OWG report, with some minor changes) (iii) the means of implementation (iv) a framework for monitoring and reviewing the agenda. The scale, ambition and approach of the agenda are unprecedented.
A key feature is that the SDGs are global and universally applicable, taking into account national realities, capacity and levels of development and specific challenges. All countries have a common responsibility to achieve the SDGs and all have an important role to play at local, national and global levels. In addition, the 2030 agenda integrates the three dimensions of sustainable development – economic, social and environmental- in a balanced way. The 2030 agenda is also indivisible, in the sense that it must be implemented as a whole and not in a fragmented manner, while recognising that the different objectives and objectives are closely linked.
