The Editors, National Review, 12 Sep. 2022 In China, the energy mix also shifted toward cleaner sources, helping to lower carbon-dioxide emissions. Sha Hua, WSJ, 8 Sep. 2022 Carbon dioxide reached an average annual concentration of 414.7 parts per million, up 2.6 parts per million over 2020. Dinah Voyles Pulver, USA TODAY, 1 Sep. 2022 On climate change, the bill pumps money into wind and solar projects, along with the batteries to store renewable energy, while also subsidizing technology to capture and store carbon-dioxide emissions.
