More importantly, a successful voluntary carbon market moves green low carbon economic activity into the free market domain, rather than the mandatory one we currently find ourselves in.
The criteria considered include population density, the distance to underground geological formations suitable for carbon sequestration, seismic activity, terrain, proximity to airports, military bases and so on and so forth.
The draft curriculum for geography does not contain references to climate change but a section called "Earth science" in the chemistry syllabus says 11- to 14-year-olds should be taught about "the production of carbon dioxide by human activity and the impact on climate" and includes a section on "the efficacy of recycling".

For example, UN types have already begun discussing levies on energy purchases, carbon emissions, international corporate activity and currency transactions.
The resulting photosynthetic activity could, in theory, increase the storage of carbon from the atmosphere into the deep ocean.
In 2010, emissions from electricity grid activity in Scotland were estimated to amount to 347 grams of carbon dioxide per Kilowatt hour (kWh) of electricity generated.
Human activity is thought to contribute about 7 billion to 8 billion tonnes of carbon dioxide every year.

But the euro crisis has reduced industrial activity (cutting pollution) and European firms were anyway given overly generous carbon quotas under the cap-and-trade scheme.
By contrast, modest black-hole activity can stir things up and encourage the formation of the kinds of elements (carbon, oxygen and so on) that are essential for life as we know it.
With respect to carbon emissions, I share the view of your Prime Minister and most scientists in the world that climate change is a real problem and that human activity is contributing to it, and that we all have a responsibility to find ways to reduce our carbon emissions.
Scientists say it's apparent that human activity -- namely burning coal, oil and natural gas -- has been driving a rapid rise of carbon dioxide levels in the atmosphere.
Emissions are falling by less than a percentage point a year, and the government has admitted that it will fail to meet a self-imposed target of a 20% reduction in carbon-dioxide emissions on 1990 levels by next year, even though the recession has cut economic activity.

The alternative, that the carbon came from the volcanoes, is unlikely because the spike is much shorter than the period of volcanic activity.
