Breaking Germany’s coal addiction….

February 19, 2019

Nice bit by Johan Rockström and Owen Gaffney.

It is scientifically well established that if the world is to keep the average increase in global temperature “well below” 2°C relative to pre-industrial levels – the “safe” limit enshrined in the 2015 Paris climate agreement – no more than another 500-800 billion tons of carbon dioxide can be emitted. On current trends, this would take just 12-20 years.

Instead, the world needs to follow a trajectory called the “carbon law,” which requires reducing CO2 emissions by half each decade until, 30-40 years from now, we have achieved a carbon-free global economy. Growing evidence shows that adhering to the carbon law is technologically feasible and economically attractive. In this process, coal – the most polluting energy source – must be the first to go, exiting the global energy mix entirely by 2030-2035.

This will be particularly challenging for Germany, which, despite its reputation as a climate leader, has long had a dirty secret: the most polluting type of coal – lignite – remains the country’s single biggest source of electricity. Although renewables have penetrated 40% of the electricity market, coal still accounts for 38%.

A decision to phase out nuclear power, spurred by the 2011 Fukushima disaster, left Germany with a significant energy gap, filled partly by coal. Germany has built ten new coal-fired power plants since 2011, bringing its total to about 120. As a result, it is set to miss its 2020 emissions goal (a 40% reduction, compared to 1990), and, barring decisive action, it could miss its 2030 target (a 55% reduction) as well.

One always thinks Germany to be efficient in whatever they do. Didn’t know this bit on its coal reliance.
