"The current system of penalizing greenhouse gas emissions through carbon taxes is not sufficient to avoid catastrophic climate change, even if very high taxes are enforced," Habiba Daggash, a doctoral student in energy systems at Imperial College London, said in a news release. "Therefore, using this strategy alone, the Paris Agreement that most countries have committed to could not be delivered."
