United Nations, Oct 28 (IANS): UN Secretary-General Antonio Guterres has urged the international community to take climate actions on all fronts, warning the window to limit global temperature rise is closing fast.

Guterres made the remarks in a video message on the release of the latest Emissions Gap Report by UN Environment Programme (UNEP) on Thursday, Xinhua news agency reported.

The report showed that under current Nationally Determined Contributions, the climate action plan to cut national emissions, the world is headed for 2.8 degrees Celsius of global heating by the end of the century.

"As today's report makes clear, we are headed for economy-destroying levels of global heating," he said. "We need climate action on all fronts -- and we need it now."

Guterres called on the international community to act to end reliance on fossil fuels, avoid a lock-in of new fossil fuel infrastructure and invest massively in renewables, citing the UNEP report's recommendations.

Developed countries must lead in boosting their national climate plans, the UN chief said, noting that emerging economies need financial and technical support to step up their climate actions.
