The 4th “Country Climate and Development Report” summary is out, covering 93 economies, with a focus on jobs.

This report is unique in that it is
based on dozens of individual-country reports, each prepared (and reviewed) individually.

Why the Time Has Finally Come for Geothermal Energy
It used to be that drawing heat from deep in the Earth was practical only in geyser-filled places such as Iceland. But new approaches may have us on the cusp of an energy revolution.

Industrialized economies are increasingly turning their backs on aid and diplomacy to build up their armies.

But analysts fear that hostile and unreliable states like Russia, China and Turkey will step in to fill the gap.

However, while the aggregate effect is expected to be small, countries need to prepare for significant sectoral and regional shifts. The report highlights measures to reduce five frictions that prevent workers to adjust to a rapidly changing labor market: skills, space, time, norms, and wages.

At the same time, the shift to low-emission development pathways, with emissions reduced by 71 percent by 2050, would have a small and most of the time positive impacts on GDP and labor income.

Key highlights include that climate adaptation could yield labor income benefits equivalent to 150 million jobs by 2050, a combination of new jobs created by investments in infrastructure or nature-based solution and jobs that are protected from negative shocks and impacts.

Encore plus personnellement je vais amèrement regretter cette ligne dans mes transits réguliers entre l’Ukraine et la France (en train c’est top)
