Im still waiting for someone to explain why everyones so obsessed with calculating their carbon footprint from transportation when its pretty clear that the methods for doing so are almost entirely inaccurate. Whats the difference, exactly, between using an online calculator that asks for nothing more than the number of miles you drive per year and actually tracking every single journey you take, down to the length of each individual trip and the type of vehicle youre driving? And dont even get me started on cyclists or pedestrians – are we just supposed to assume that our carbon footprint is essentially zero, or is there a more nuanced way of calculating the impact of, say, the production and transportation of our bicycles or the food we eat to fuel our rides?
