Tree Totaller

Greenfleet’s Tree Totaller is a simple way to estimate your annual greenhouse emissions from your use of a car, your household and your air travel.

As a household, we’re running at an annual rate somewhere between 30 and 40 tonnes. (The indeterminacy here is chiefly due to my ignorance about the number of flights we’re making this year.) Our car useage is a pretty skimpy 1.8 tonnes.


I’m Greg Restall, and this is my personal website. I am the Shelby Cullom Davis Professor of Philosophy at the University of St Andrews, and the Director of the Arché Philosophical Research Centre for Logic, Language, Metaphysics and Epistemology I like thinking about – and helping other people think about – logic and philosophy and the many different ways they can inform each other.
