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

A study by the University of Manchester calculated the emissions of CO2—the main greenhouse gas responsible for climate change—at every stage of microwaves, from manufacture to waste disposal.

However, David Reay, professor of carbon management, argues that, although microwaves use a great deal of energy, their emissions are minor compared to those from cars.

The authors also calculate that the emissions from using 19 microwaves over a year are the same as those from using a car.

The extensive data sources, combined with computer simulations, created a timeline of ocean temperature changes, including cooling from volcanic outbreaks and warming from fossil fuel emissions.

This is 10 times the amount this new microwave oven study estimates for annual emissions for all the microwave ovens in the EU.

We must cut carbon emissions by 80% from their 2006 levels by 2020, stabilize the world's population at eight billion by 2040, completely remove poverty, and restore forests and soils.

Amazon plants, for instance, hold more than 100 billion metric tons of carbon, equal to 15 years of tailpipe and chimney emissions.

carbon emissions are the leading cause of current global warming

Its inability to curb the carbon emissions from industries.

In face of global warming, much effort has been focused on reducing greenhouse gas emissions through a variety of strategies.

That sense of urgency has increased interest in capturing and storing CO2, which the IPCC says could provide the more than 50% reduction in emissions thought needed to reduce global warming

However, scientists say that the scale of CO2 emissions will require vast amounts of long-term storage.

What does the author say is a forward thinking strategy concerning the reduction of CO2 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.

According to the International Business times, electric car sales are expected to increase as Volkswagen is still recovering from its emissions scandal.

Actually, it has to translate into more urgency to deal with the climate change problem and reduce emissions.

As a country's wealth grows, so do its greenhouse gas emissions.

As countries continue setting goals of reducing emissions, greater steps need to be taken to have a noticeable effect on the surrounding environment.

But could Norway keep its standard of living and yet cut its emissions to Moroccan or even Ethiopian levels?

But their top safety concerns are emissions and wireless radio waves.

Despite mournful polar bears and charts showing carbon emissions soaring, most people find it hard to believe that global warming will affect them personally.

Developed nations such as Australia, the United States, Canada, and European countries are essentially climate "free-riders": causing the majority of the problems through high greenhouse gas emissions, while incurring few of the costs such as climate chan

Economic reasoning shows that the least expensive way for each country is to put a price on carbon emissions.

Failure to address comprehensively the problem of greenhouse gas emissions, however, exposes all generations, present and future, to incalculable risks.

Fewer than 4% of countries are responsible for more than half of the world's greenhouse gas emissions.

However, the agreement specifies that there is no formal distinction between developed and developing nations in their responsibility to cut emissions, effectively ignoring historical emissions.

If the Thames were lapping around Big Ben, Londoners would face up to the problem of emissions pretty quickly.

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.

Many of the world's most climate-vulnerable countries, the majority of which are African or small island states, produce a very small quantity of emissions.

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.

More than $100 billion in funding has been put on the table for supporting developing nations to reduce emissions.

Nations from around the world have gathered in Paris for the United Nations Climate Change Conference, COP 21, with the goal of a universal and potentially legally-binding agreement on reducing greenhouse gas emissions.

Part of the reason this ban is being discussed and implemented is because energy officials see that they will not reach their emissions goals by 2050 if they do not eliminate a large portion of vehicle emissions.

Politicians may tackle polluters while scientists do battle with carbon emissions .

Sommerkorn says a plan to reduce greenhouse gas emissions blamed for global warming needs to come out of the Copenhagen Climate Change Summit in December.

The country is still hopeful that it will meet its emissions goals, like reducing emissions by 40% by 2020, but the acceptance of electric cars in the country has not occurred as fast as expected.

The International Monetary Fund calculates that countries can generate substantial fiscal revenues by eliminating fossil fuel subsidies and levying carbon charges that capture the domestic damage caused by emissions.

The level of emissions they cause will depend on how the electricity to run them is generated, while brakes, tyres and toads all create tiny airborne particles as they wear out.

The reason is that when carbon is priced, those emissions reductions that are least costly to implement will happen first.

The result would be higher emissions of carbon dioxide and other greenhouse gases.

The same is true for new technologies for alleviating fossil fuel emissions.

Their approach is flexible enough that in principle other important quality-of-life changes could be incorporated—for example, decreases in total emissions of pollutants and declines in crime rate.

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.

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.
