World leaders agreed on Monday to take immediate action to unlock "more and better financing" for developing countries.

The information was announced by the United Nations (UN) after the Sustainable Development Goals (SDG) Summit.

According to the UN, quoted by Lusa, the leaders adopted a "decisive and action-oriented" political declaration yesterday, highlighting their collective commitment to building a sustainable, inclusive and prosperous world by 2030, the deadline for achieving the SDGs.

"With a strong focus on the means of implementation and, in particular, financing for development, the Declaration recognizes that without a quantum leap in investments to enable energy, food, fair and equitable digital transitions and a transformation in education and robust social protection in developing countries, the goals will simply not be achieved," the UN said in a statement.

The Declaration also calls for immediate action to implement a stimulus proposed by UN Secretary-General António Guterres, in terms of a massive increase in funding to achieve the SDGs: 500 billion dollars a year.

According to Guterres, this funding could be "a watershed" in the progress of the SDGs.

The Declaration reached on Monday also conveys strong support from all countries for a reform of the international financial architecture to better reflect today's global economy.

In 2015, world leaders made a historic global promise to guarantee the rights and well-being of all citizens when they agreed to the 2030 Agenda and the 17 SDGs.

However, with seven years to go until that deadline, only 15% of the SDGs are on track to be achieved.

Faced with this "worrying" scenario, the UN has convened the SDG Summit, where more than 100 countries will present national commitments to accelerate these goals, including priority transitions and investment areas.

In addition to these national commitments, developed countries and other countries that have the capacity are expected to make individual global commitments.

The US ambassador to the UN, Linda Thomas-Greenfield, announced today that the United States has adopted this "historic political declaration" on the SDGs, considering it an "important step", but one that "must be followed by accelerated action".

"All member states must continue to push for progress. The world's most vulnerable are counting on us and we must leave no one behind," she said.

"While there are great challenges ahead, we cannot allow realism to be an excuse for cynicism. It is within our grasp to end hunger and tackle the climate crisis, break the cycle of poverty and strengthen public health systems, eradicate gender inequality and defend human rights, and make progress on all 17 SDGs," he stressed.
