States team up in push for electric heavy vehicles

The big picture: "While trucks and buses only account for 4 percent of vehicles on the road, they are responsible for nearly 25 percent of total transportation sector greenhouse gas emissions," the announcement states.

• It also notes that medium- and heavy-duty vehicles account for lots of smog-forming and particulate pollution, which disproportionately affects poor people and communities of color.

How it works: The MOU sets a goal of having electric models account for all medium- and heavy-duty vehicle sales in their states by 2050, and a nearer-term goal of 30% by 2030.

• The states involved include California, New Jersey, New York, Colorado, Pennsylvania and North Carolina.

What's next: The agreement calls for creating a joint plan within six months that includes suggestions for...

• Incentives states can adopt.
• Plans to have public transit and other government agencies increase deployment.
• Infrastructure strategies.
• Plans to work with private fleet managers.
