It estimates that the cost of the big emissions cuts required would more than double without CCS.
"I don't think Brazil, or most of Latin America, will end up soon making the choice to ensure big emissions reductions just for the sake of increased responsibility".
He set out key aspects of the Copenhagen deal: big emissions cuts for rich countries, curbing of emissions for developing countries and money from rich to poor to pay it.
That is partly because the treaty left out big emissions sources such as deforestation (see article), but also because potential participants were put off by the idea of internationally binding commitments.Australia has proposed another route.
Some conservative groups opposed to big emissions cuts pointed out happily that the agency was essentially calling for more research and putting off any commitment to cuts until late next year at the earliest.
If China's effort is accompanied by big emissions cuts by rich countries, he says, then there is a good chance of avoiding rises in the global average temperature of beyond 3.6 degrees Fahrenheit above the preindustrial average, which most governments have agreed is a dangerous threshold.
"There are increasing rural environmental problems with relatively big emissions of pollutants from agricultural sources…The pollution of livestock and poultry farms has not been under effective control". Interpretation: The countryside is at risk of becoming a toilet with 243m tonnes of faeces and 163m tonnes of urine from livestock, according to the latest survey.
The findings will help scientists disentangle inputs and outputs in places like the Amazon rainforest, where there are both big emissions from deforestation and big sinks from photosynthesis.
The plastic, cardboard, and paper used in packaging is manufactured in great big emissions-spewing factories, so try to buy items with as little packaging as possible.
If the pool was bigger, emission fell to 10.6 g/d per sow because, though the larger emitting area increases ammonia emission, the increase is outweighed by the reduction in emission caused by successive, superseding urinations on the same spot.
