Carbon emissions from China could peak as soon as 2021, which is nine years before the voluntary deadline in their Paris agreement pledge, a new peer-reviewed study finds.

Why it matters: China is by far the world's largest carbon emitter. The trajectory of its emissions affect whether the world has any chance of meeting the Paris temperature goals — or, more likely, how much they're overshot.

What they did: The paper in Nature Sustainability looks at China's urbanization trends and the emissions increases that come with it.

  • They explore China's massive existing and developing cities and growing wealth through the lens of an environmental "Kuznets curve."
  • It's the idea that per-capita emissions initially rise alongside per-capita GDP, but it's a bell-shaped curve in which higher incomes are eventually correlated with emissions decline.

What they found: China's cities and urban centers defy blanket characterization — they note a "great diversity in CO2 emissions and trends among individual cities." But in the aggregate...

"We project that China’s total emissions from fossil fuel and industrial processes will peak at 13–16GtCO2 at some point 5–10 yr ahead of 2030 on the basis of data from the 50 Chinese cities studied here over the period 2000–2016."

The intrigue: The paper says that policymakers will need to tailor policies to the characteristics of different cities and regions and their stage of development.

  • For cities in economically advanced regions where industrial emissions may have already peaked or are close, that means more attention to lower-carbon lifestyles, efficient buildings, transport and renewables deployment.
  • But for other areas seeing fast industrialization and urbanization, "efforts to constrain emissions should focus more on industrial sectors."
  • In addition, it emphasizes the need to prevent "carbon leakage," whereby energy-intensive industries are just moved out the most developed cities.

President Biden told congressional leadership in a letter Saturday that this week's airstrike against facilities in Syria linked to Iranian-backed militia groups was consistent with the U.S. right to self-defense.

Why it matters: Some Democrats, including Sens. Tim Kaine (D-Va.) and Chris Murphy (D-Conn.) and Rep. Ro Khanna (D-Calif.), have criticized the Biden administration for the strike and demanded a briefing.

The Food and Drug Administration on Saturday issued an emergency use authorization for Johnson & Johnson's one-shot coronavirus vaccine.

Why it matters: The authorization of a third coronavirus vaccine in the U.S. will help speed up the vaccine rollout across the country, especially since the J&J shot only requires one dose as opposed to Moderna and Pfizer-BioNTech's two-shot vaccines.
