Sesame Street Season 40 premiered on November 10, 2009. This date is the 40th anniversary of the show, and Sesame Workshop has been celebrating the occasion with a commemorative book and DVD set, as well as a week-long takeover of the Google logo.

The curriculum for Season 40 focuses on environmentalism and is "designed to nurture young children's appreciation and love for nature." The Muppets of Sesame Street encourage children to explore their curiosity in the outdoors with activities that teach simple, age-appropriate ways of showing care and stewardship for the environment.

Episodes
Several episodes focus on environmental issues - such as recycling or habitats. One episode (Episode 4193) focuses on Baby Bear and his family learning how to hibernate. Another episode (#4187, originally planned as #4210) features Big Bird learning about migration.

In an interview with Muppet fansite Tough Pigs, writer and Muppeteer Joey Mazzarino said, "We're trying to do what we call a hidden gem in every episode. That's for you guys, the fans. Little things like Biff and Sully in a scene, or some other stuff that I won't tell you about that will be hidden in the scene."

The season also introduces a new format based on typical channel programming blocks, with Murray Monster serving as a host from real-world locations, introducing the main components of the show. Also added to the episodes is a new computer-generated segment, Abby's Flying Fairy School.
