Mr Obama's plan to curb carbon dioxide (CO2) emissions (排放), though necessary, will be far from cost-free, whatever his sunny speeches on the subject might suggest.
optimistic about Obama's effort to reduce CO2 emissions
According to the author, Obama's plan to limit carbon dioxide emissions will by no means be inexpensive.
Annan stressed the need for the negotiations to focus on increasing the flow of money from rich to poor regions to help reduce their vulnerability to climate hazards while still curbing the emissions of the heat-trapping gases.
How emissions of heat-trapping gases can be reduced on a global scale
And it would take an average of 65 years for the reduced carbon emissions from a new energy-efficient home to make up for the resources lost by destroying an old one.
carbon emissions come from heating, cooling and powering our homes, offices and other buildings
While alternative estimates of the damage from carbon emissions differ, and it's especially hard to reckon the likely costs of possible catastrophic climate events, most estimates suggest substantial negative effects.
We need very broad participation to fully address the global tragedy that results when countries fail to take into account the negative impact of their carbon emissions on the rest of the world.
The same is true for new technologies for alleviating fossil fuel emissions.
The result would be higher emissions of carbon dioxide and other greenhouse gases.
The reason is that when carbon is priced, those emissions reductions that are least costly to implement will happen first.

In order to maximize global welfare, every country's carbon pricing should reflect not only the purely domestic damage from emissions, but also the damage to foreign countries.
Higher fossil fuel prices prove to be conducive to innovation and application of cleaner technologyIf fossil fuel prices remain low for a long time, it may lead to higher emissions of greenhouse gases.
Greenhouse gas emissions, if not properly dealt with, will pose endless risks for mankind.
Failure to address comprehensively the problem of greenhouse gas emissions, however, exposes all generations, present and future, to incalculable risks.
Economic reasoning shows that the least expensive way for each country is to put a price on carbon emissions.
A tax on upstream carbon sources is one easy way to put a price on carbon emissions, although some countries may wish to use other methods, such as emissions trading schemes.
Measuring emissions is not a precise science, particularly when it comes to issues surrounding land use; not all nations have released up-to-date data, and in any case, emissions from some sectors such as aviation are not included in national statistics.
But could Norway keep its standard of living and yet cut its emissions to Moroccan or even Ethiopian levels? That question, repeated across a dozen environmental issues and across our diverse planet, is what will ultimately determine whether the human race is living beyond its ecological means as it pursues economic revival.
