I, admittedly, pay no attention to my carbon footprint. I make my decisions on a selfish basis -- what is good for me, not good for the planet.

That said, I believe that what I consider to be best for me very often turns out to be the most environment-friendly choice.

Some examples:

**Over a decade ago I forked out to buy, and have installed, a solar water heater on my roof. I did not do so in order to reduce the amount of fuel needed to heat up the water in my house. I did so in order to save money. For most of the year, I do not have to turn on my back-up water heater at all. For the rest of the year, turning it on for about 2 hours a day is sufficient.

**Long before various state governments began banning plastic straws in restaurants, I have refused all straws (plastic or paper) when ordering a cold drink in a restaurant or cafe. In Israel, they are served in the drink and, not being 7-years-old, I get no particular pleasure in sipping my drink through a straw. I would rather bring the glass (or the bottle) to my mouth. On top of that, if they bring my drink with a straw in it, I have to take the straw out and it drips all over the table.

**For many years I had to go to/from Tel Aviv once a week. I could either drive 2 hours in each direction or go to a local airport and fly 20 minutes to Tel Aviv. The latter, obviously, was much easier for me so I chose that. Clearly, the flights gave me a much smaller carbon footprint than driving would have.
