Global efforts to tackle climate change are way off track says the UN, as it details the first rise in CO2 emissions in four years.

The emissions gap report says that economic growth is responsible for a rise in 2017 while national efforts to cut carbon have faltered.

To meet the goals of the Paris climate pact, the study says it’s crucial that global emissions peak by 2020.

But the analysis says that this is now not likely even by 2030.

The report comes days before a major UN climate conference starting in Poland from 2-14 December.

For the last nine years, UN Environment have produced an assessment of the latest scientific studies on current and future emissions of greenhouse gases.

It highlights the difference between the level of greenhouse gas emissions that the world can sustain to keep temperatures within safe limits, with the levels that are likely based on the promises and actions taken by countries.

This year’s report records the largest gap yet between where we are and where we need to be.
