On April 22nd 2016, one hundred seventy-four states and the European Union signed the Paris Agreement; an international framework that aims to avert an irreversible climate catastrophe. Aware of the disastrous consequences climate change has on our planet these nations compromise, inter alia, to keep global warming at least under 2ºC, with an ideal target of 1.5ºC.
Since April 2016, many efforts have been made to restrain the causes of global warming yet climate scientists warn the 1.5ºC target will not be met unless global carbon emissions reach net-zero around mid-century. Luckily, mechanisms exist to achieve “net-zero”: Negative Emission Technologies.
