Governments and non-state actors need to deliver an urgent increase in ambition to ensure the Paris Agreement goals can still be met, according to a new UN assessment, the United Nations Environment Program said in a Tuesday report.

The eighth edition of UN Environment’s Emissions Gap report, released ahead of the UN Climate Change Conference in Bonn, finds that national pledges only bring a third of the reduction in emissions required by 2030 to meet climate targets, with private sector and sub-national action not increasing at a rate that would help close this worrying gap.

The Paris Agreement looks to limit global warming to under 2oC, with a more ambitious goal of 1.5oC also on the table.

Meeting these targets would reduce the likelihood of severe climate impacts that could damage human health, livelihoods and economies across the globe.

As things stand, even full implementation of current unconditional and conditional Nationally Determined Contributions makes a temperature increase of at least 3 oC by 2100 very likely – meaning that governments need to deliver much stronger pledges when they are revised in 2020.

Should the United States follow through with its stated intention to leave the Paris Agreement in 2020, the picture could become even bleaker, read the report.

The report does, however, lay out practical ways to slash emissions through rapidly expanding mitigation action based on existing options in the agriculture, buildings, energy, forestry, industry and transport sectors.

Strong action on other climate forcers – such as hydrofluorocarbons, through the Kigali Amendment to the Montreal Protocol, and other short-lived climate pollutants such as black carbon – could also make a real contribution, it added.
