The idea of Domestic Tradable Quotas (DTQs), also variously referred to as Personal Carbon Allowances, Tradable Energy Quotas, or just Personal Carbon Trading has been around since the mid 1990s. Such a system would require government intervention. It would involve the free distribution, on a per-capita basis, of carbon credits which would be exchanged for carbon-intensive goods, like fuel. Those with surplus credits can sell them, those who run out must buy them. It could be an excellent way of moving us all towards a more sustainable level of CO2 emissions. But can we act fast enough?
