The High Cost of Green

Copenhagen wants to be the world’s first CO2-neutral city by 2025. But this initiative, however wonderful it sounds, is little more than a costly vanity project.

After all, the whole accounting exercise works only if others are still using coal and gas that Copenhagen’s unpredictable wind power can replace. If the city's unrealistic assumptions fall short, the financial losses for its inhabitants will be substantial.

Our current climate conversation embodies two blatantly contradictory claims. On one side, experts warn that promised climate policies will be economically crippling. In a new report, the International Energy Agency (IEA) states that achieving net-zero in 2050 will likely be “the greatest challenge humankind has ever faced.” That is a high bar, surpassing the Second World War, the black plague and COVID.

I thought I would enter the great halls of Plato, but instead I entered the halls of an intellectual sausage factory. I wanted to do something not on the main course, and chose the environment.
