- Home Depot is funding the planting of 300,000 trees in cities across the US to help absorb carbon dioxide (CO2) emissions... The CO2 emissions from only one medium-sized (500 MW) coal-fired power plant, in just 10 days of operation, will negate this entire effort. Wal-Mart is investing a half billion dollars to reduce the energy consumption and CO2 emissions of their existing buildings by 20% over the next seven years. If every Wal-Mart Supercenter met this target… The CO2 emissions from only one medium-sized coal-fired power plant, in just one month of operation each year, would negate this entire effort. NY, ME, VT, NH, MA, CT, RI, PA, NJ, DE, MD The Regional Greenhouse Gas Initiative (RGGI) is a cooperative effort by 11 Northeastern and Mid-Atlantic states to reduce their CO2 emissions to 1990 levels by 2014... The CO2 emissions from just 13 medium-sized coal-fired power plants each year will negate this entire effort.

- America's proposed "Bold Energy Plan" would supply a meager three percent of the 118 QBtu of energy that the Energy Information Administration projects America will consume in 2030. The 2030 Blueprint, a three-pronged solution centered on building energy efficiency, homeowner choices and renewable energy, would supply as much as 37% of America's total energy consumption, replace 100% of its fossil-fuel-generated electricity and reduce its imported oil by as much as 89%.

The measures below the horizontal line have a negative abatement cost – in other words, by carrying them out, people and companies could both cut emissions and save money. At a macroeconomic level they would boost, rather than reduce, economic growth. Why isn’t more policy geared towards these sure winners? Possible explanations: the savings are too small; the numbers of people involved to carry them out are too large; developers would have to pay higher capital costs up front, but are not paying for the electricity in the long run; people buy houses for the view not for the insulation.

- Natural capital, in other words, ecosystem services upon which all life on earth depends. Our human economies depend on these services. Human enterprise has tended to see nature as a source of raw materials to be exploited. This has the effect of spending our capital, instead of living off the interest. Any investment advisor would tell you this is not smart. The three priorities must be balanced – no one is more important than the other

- What does this mean to a business or community? * We are now seeing a decline in living systems: soil, fisheries, forests. * This means resources and ecosystem services on which our businesses and communities depend are diminishing. * At same time demands on biosphere are increasing. * Population may double in next 50-60 years from 5.8B to 12B. * Third world countries aspire to consumption level we have. * Technology is making us more labor efficient but increasing our use of natural resources and energy. * Margin for action is narrowing.
