The U.N. shipping agency has reached an agreement to cut carbon emissions "by at least 50 percent by 2050," Reuters reports, although they added that the goal "fell short of more ambitious targets."

Why it matters, from Axios' Ben Geman: Shipping is estimated to account for 2-3% of global CO2 emissions, but that share is projected to rise sharply to 17% by mid-century, absent more steps to tackle the problem. The agreement also highlights the challenge of curbing emissions from the wider transportation sector, even as cars and light trucks grow more efficient and move towards greater electrification.
