The European Commission president on Saturday asked G20 leaders to join a proposal to create a global carbon price. Many countries use a carbon price to help meet their climate goals, either in the form of a tax or under an emissions trading system (ETS) or cap-and-trade system. According to a World Bank report, there are currently 73 carbon pricing instruments in operation, covering about 23 trillion tons of global greenhouse gas emissions. “Climate change is human-caused. So that means we can solve it. To do that we need innovation, investment in green technologies, renewable energy capacity and energy efficiency… At the G20, I invited leaders to join the call for global carbon pricing,” Ursula von der Leyen wrote on the social network X, formerly known as Twitter. Leyen is pushing the international community to introduce global carbon pricing to accelerate the transition to a low-carbon economy. (Reuters).
