emission

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.

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.

The nations participating at COP 21 are focusing on quantitative emissions-reduction commitments.

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.

Pricing carbon proves the most economical way to reduce greenhouse gas 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.

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.

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

There must urgently be a meaningful mobilisation of the policies outlined in the agreement if we are to achieve national emissions reductions while helping the most vulnerable countries adapt to climate change.

The goal of keeping global temperature rise well below 2 ℃ is commendable but the emissions-reduction pledges submitted by countries leading up to the Paris talks are very unlikely to deliver on this.

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

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.

It will motivate all nations to reduce carbon emissions.

It will effectively reduce greenhouse emissions worldwide.

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.

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

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 change's impact on food and water.

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

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

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

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

The new ultra-low emission zone Ulez is likely to be a big issue in next year's mayoral election.
