Cong. Ed Markey is the prize attraction of this year's fundraiser for the Environmental League of Massachusetts, whose 13th annual Earth Night is May 27. Markey's main task these days is the climate and energy bill that carries his name and Henry Waxman's. (A revised version was released on Friday, and the Committee on Energy and Commerce is meeting today to consider it. Here's a summary.)

Markey will hobnob with ELM donors of a certain level from 5:30-6:30, and will later address the full group, which ELM touts as Boston's largest environmental event. 

In addition to the talk, awards will be given out for environmental service of one sort or another, and ELM will host an auction that includes pairs of high-end Red Sox tickets and opportunities for environmental travel to Washington State's San Juan Islands and elsewhere.

Tickets are $150 and up; the venue is the Omni Parker House, 60 School St., Boston. You can purchase tickets online here.
