Grossi's tweet asked, "How big is your carbon footprint?" Intrigued, I clicked on the site. Nature Conservancy.
So far, so good. I took the bait, entered the information for a four-person household, three-bedroom home in California. The brief survey asked questions about heat and home efficiency, lighting, use of Energy Star appliances and measures taken to reduce hot water use.
Not the most illuminating. But, I guess, not bad.
The survey also asked for a list of our cars, how fuel efficient they were and how many miles driven in a year. Other questions included how often an air filter on the furnace/AC was replaced and how often tire pressure is monitored.
The final question boosted my family's footprint. We took the equivalent of six short flights in the past year. Peg and I went to Vegas, she and I to Bellingham, Wash. to visit our latest grandchild and she and Calvin, our oldest son, went to check out two colleges in Seattle.
