The Covid-19 pandemic will lead to a significant and lasting reduction in global energy demand and fossil fuel use but falls in emissions are still unlikely to be enough to meet the targets of the Paris climate agreement, according to new research.

A new report by technical advisory firm DNV GL said Covid-19 has hastened the decline in global carbon dioxide emissions – with 2019 set to be the year that CO2 output hit its peak.

However, the overall impact on emissions will be “minimal”, said DNV GL in an early release of some of the findings of its annual energy transition outlook.
