The implementation of a global tax on greenhouse gas emissions could – without other complementary policies – “have a greater negative impact on global hunger…than the direct impacts of climate change”, a new study says. The research finds that using a blanket “carbon tax” to restrict global warming to 2C above pre-industrial levels – which is the limit set by the Paris Agreement – would put an additional 45 million people at risk of hunger by 2050. However, the results “should not be interpreted to downplay the importance of future GHG [greenhouse gas] emissions mitigation efforts, or to suggest that climate policy will cause more harm than good”, the scientists say. Instead, the findings should highlight the need for “complementary policies” that would “counteract the impacts of the climate change mitigation policies on vulnerable regions”, they add.
