US Treasury names green financier as climate ‘czar’ Reuters, WASHINGTON The US Department of the Treasury on Monday named climate change financial adviser John Morton to head the department’s new “climate hub,” disappointing activists who had sought a strong regulator to push financial institutions toward green investments. John Morton, a partner with climate change advisory and investment firm Pollination Group, would work to foster green finance, and use tax policy and financial risk assessments to help reduce carbon emissions as climate counselor to US Secretary of the Treasury Janet Yellen, the department said. Morton brings more than 25 years of experience in emerging markets, investment finance, and economic and environmental policy, it said.
