For those of us reading this who would like to genuinely and effectively offset emissions, is anyone able to suggest some really robust schemes where you can be confident the offsets are real? I'm especially interested in schemes where I can be confident buying additional credits has a marginal impact. I've used an investment in the Solar Schools coop [1] for this in the past, which I'm confident is 'real', but there are probably much cheaper ways. One of the reason I liked the coop is that it (presumably) also helps kids to learn about renewable energy, and helps schools with their energy bills.
