Thanks to your feedback, we've updated our carbon calculator to make it easier to use. Try it and let us know what you think. But before you do, you'll need to reset your password to ensure your account is secure on our new site. We'll email you a a password reset link, so be sure to use the same email address you originally used when you first tried Project Neutral. If that email address is no longer active, you can create a new account.
