The climate change deal is expected to be signed by 171 countries on Earth Day, which is to break the record from 1982, when 119 countries on the same day signed the UN Convention on the Law of the Sea.

Before the signing a ceremony was held at the UN headquarters, which was addressed by senior UN officials, US Secretary of State John Kerry and US actor Leonardo DiCaprio.

The signing was followed by a presentation of national plans for the implementation of the treaty.

The Paris global climate change deal will enter into force 30 days after it is ratified by 55 countries that generate 55% of all greenhouse gas emissions, with China and the US contributing 40%. Today, at least 13 countries submitted ratification documents together with their signatures.

Apart from committing the planet to limiting warming to 1.5 degrees Celsius over pre-Industrial Revolution temperatures, the accord, signed by envoys from 195 nations last December, also sets a new goal of net zero emissions by the second half of this century.

The signatories will have to present their goals, which will not be legally binding. The goals are to be upgraded every five years with the first cycle starting in 2020.

Countries will report on their progress. The most vulnerable and the least developed countries will receive aid to meet their goals.

Withdrawal from the treaty is possible only three years after the beginning of its implementation and following the expiration of the notice period.

Due to its geographical specifics, Slovenia has recorded a bigger increase in temperature since the end of the 19th century that the global average. Temperatures have risen by 1.5 degrees Celsius, which has already started to show negative effects, according to Zoran Kus, Slovenia's chief negotiator on climate change.

Slovenia will be striving for a fair distribution of burdens in the negotiations on the implementation of the treaty, he told the STA.

The country will refer to its specifics such as large forest areas and increased transit transport, which is a result of this. It will be arguing for additional EU-level measures from reduction of emissions from this type of transport.

According to Kus, the treaty will encourage new green investments in Slovenia, generate jobs, a more healthy environment, efficient use of renewables and other natural resources.

"Slovenia will be actively involved in the talks on the new measures and regulations and then transfer the agreed measures into its legislation as soon as possible," Kus asserted.
