Reducing CO-2 concentrations by scrubbing the air.  University of Calgary scientists claim that they can remove CO-2 from the air at a cost of $10 per ton.  Since some carbon tax proposals would tax CO-2 at $30 per ton, this new technology is a promising development.

Regulations on Food Consumption Urged to Reduce Greenhouse Gas Emissions.   A recent report by the Food Climate Research Network is described in news reports as calling for worldwide "rationing" of consumption of meat, alcohol, chocolate, and other foods that have high greenhouse gas impact relative to their nutritional value.   The report itself, while not specifically using the term rationing,  does say:

"Changes in behaviour – in what and how we eat – are essential. As priorities, we need to reduce our consumption of meat and dairy foods, to eat no more than we need to keep ourselves healthy, to limit consumption of food that is of little nutritional value, and not waste food. Efforts to encourage us voluntarily to change will not achieve what is needed in the time available. Regulatory and fiscal measures that change the context within which we consume are vital.."
