More than 50 world leaders are set to attend the 2019 United Nations Climate Change (COP25) conference which will lay the bases for a new phase of climate action.

The Climate Summit starts on Monday in Madrid. The event was supposed to take place in Chile in December but was moved due to civil unrest in the country.

COP25 is the last UN Climate Summit before 2020 when many nations must submit new climate action plans.

"In Chile and in the world we are experiencing social and environmental crises. In order to face them, we must return to our roots: we must listen to each other to rebuild trust and dialogue with a willingness to change", explained Chilean environmental minister Carolina Schmidt.

Ms. Schmidt, who will preside over the negotiations during the summit, claimed that climate change is "unfair" as it mainly affects vulnerable people, communities and countries.

The fortnight- long summit kicks off against the backdrop of a high level of climate interest in the UK election as well as warnings by the United Nations that global emissions have climbed 5% a year on average for the past decade.

Before the official opening, Spain's acting Prime Minister Pedro Sánchez will meet the heads of state and government of the EU countries and the UN Secretary-General, António Guterres. During the afternoon, he will meet the leaders from Latin America.

Speakers include the new European Commission President Ursula von der Leyen who has set high targets in the European Union's policy to combat climate change, pledging to reduce the bloc's carbon emissions by at least 50% by 2030.

China and the European Union (EU) are key players in this summit as they are expected to make an announcement at a joint summit next September of their more ambitious carbon plans.

However, tensions have flared between China and the EU over the Paris summit proposals for a ‘carbon border tax’ which could complicate matters.

By 2020, countries are expected to upgrade their carbon- curbing plans for the first time and also outline their potential long- term plans to get net zero emissions, ahead of a crunch summit in Glasgow next year.
