In defence of net zero Share Concerns about the efficacy of net zero targets are justified, but could condemnation of the concept from Greta Thunberg and others inadvertently serve to undermine efforts to decarbonise? "The enemy of a good plan is the dream of a perfect one" Carl von Clausewitz, 1780-1831 The backlash is underway. And it's coming from the unlikeliest of quarters. For much of the past two years the global push to deliver net zero emissions has enjoyed a remarkable golden run. National and state governments have rushed to announce long term net zero emissions goals, to the point where around two thirds of global GDP is now covered by some form of target. Businesses and investors have followed suit, with over 2,100 of the world's largest corporates having set net zero goals under the UN-backed Race to Zero campaign while asset managers and owners worth trillions of dollars have pledged to deliver net zero emission portfolios by mid-century at the latest.
