The war in Ukraine may be considered a blessing from the point of view of climate, because it speeds up development and investment in green energy in the long term, even though fossil fuels are used on a limited scale, Petteri Taalas, secretary general of the World Meteorological Organization, told the AP.

Taalas acknowledged that the war in Ukraine was a shock to the European energy sector and caused an increase in the use of fossil energy.

On a timeline of five to ten years, it's clear that the war in Ukraine will accelerate our consumption of fossil energy. So we're going to invest a lot more in renewables, energy conservation solutions, and some small nuclear reactors are likely to be commissioned by 2030 as 'part of the solution.' So from a climate perspective, the war in Ukraine can be seen as a boon, Taalas added.

He noted that the energy sector currently accounts for about three-quarters of heat-trapping greenhouse gas emissions and called for a complete transformation of the global energy system.
