Lopez, Donna ATTACWMENTB From: Joshua Hartshorne <[email removed]> Sent: Tuesday, May 21, 2019 8:58 AM To: City Manager; Lopez, Donna Subject: Cambridge Net Zero Plan I am writing to express my disappointment at the scale of the Net Zero Plan and the progress so far. All the science shows that reaching net zero by 2050 is way too late. If the world doesn't reach net zero well before 2050, Cambridge is going to be under water, and this effort will have been largely wasted. And since Cambridge is a wealthy, educated city that is in danger of being submerged, we can't really expect other cities to be more aggressive in fighting climate change than we are. L urge the city to take this opportunity to upgrade the Net Zero Plan and take leadership on this issue. Josh Hartshorne East Cambridge
