The United Nations has urged for new deadlines and targets if the aims of the 2015 Paris climate accord can be achieved, as too many countries were already falling behind in their commitments.

The statement comes as the UN Climate Change Conference COP25 officially opened in Madrid, capital of Spain on Monday, where delegates are discussing measures to implement the 2015 Paris Agreement.

The major task of the conference is to discuss Article 6 of the Paris Agreement, the measures to promote voluntary international cooperation by paying a price on carbon, emission trading schemes and other market mechanisms.

The conference was convened as global efforts to mitigate climate change are on the brink of failure.

According to a UN Environment Programme report published last week on the emissions gap, countries have collectively failed to stop the growth in global greenhouse gas emissions, meaning that deeper and faster cuts are now required.

The report says that emissions have gone up by 1.5 percent per year in the last decade. In 2018, emissions totaled 55 gigatonnes of CO2 equivalent. This is putting the Earth on course to experience a temperature rise of 3.2 degrees Celsius by the end of this century, rather than 1.5-degree goal set in the Paris Agreement.

The report named the United States as one of several large emitters alongside Brazil and Japan that falling short of its own targets, or what are called "Nationally Determined Contributions".

But last month, the Trump administration filed paperwork to quit the Paris Agreement in the first step of a formal withdrawal process.

However, in an earlier interview with China Global Television Network (CGTN), former UN Secretary General Ban Ki-moon said the Paris Accord was not implemented evenly due to U.S. retreat.

"I'm concerned that Paris Climate Change agreement implementation has not been even and has not been sufficient. Particularly when the United States announced to withdraw from this Paris Climate Change agreement, it has given very serious negative political impact," said Ban.

The report also reveals what's needed to get the situation back on track by limiting global temperature rises to 1.5 degrees Celsius above pre-industrial levels, as set out in the Paris accord in 2015.

It said despite the bad start, the target was still achievable, but would require a huge effort over the next ten years.

Unless global greenhouse gas emissions fall by 7.6 percent annually between 2020 and 2030, the world will miss the opportunity to get on track towards the 1.5 degrees Celsius temperature goal of the Paris Agreement

The UN has warned of huge global changes if that target is not met. Changes that could have a catastrophic effect on the world we live in, such as the loss of nearly all coral reefs and most of the Arctic's sea ice and the rising sea-levels that come with it.
