2411 examples of Carbon in a sentence

As an economist, I favor an auction-based cap-and-trade system to put a price on carbon.
To be sure, there are still holdouts, like Australian Prime Minister Tony Abbott, who replaced a carbon tax with a plan to tax the country’s citizens in order to pay polluters to cut emissions.
His orders would rescind the Clean Power Plan regulations of the US Environmental Protection Agency; roll back standards to control methane releases from oil and gas production and distribution; and end the regulatory use of a “social cost of carbon,” introduced by the EPA to calibrate the dollar value of climate damage caused by the emission of an additional ton of carbon dioxide.
No matter how many schoolchildren are gunned down or what the scientific evidence may be for the effects of carbon dioxide emissions, people will not change beliefs that define their identity.
Despite China’s official hard line, some Chinese environmental officials privately express alarm at run-away carbon emissions, and suggest that foreign green tariffs would actually strengthen their hand in domestic policy struggles over controlling greenhouse gases by helping to win political support for emissions cuts.
It has been several years since private investors and states began buying and leasing millions of hectares of farmland worldwide in order to secure their domestic supply of food, raw commodities, and biofuels, or to get subsidies for carbon storage through plantations.
In China, political leaders seem genuine in their commitment to reduce the carbon content of their runaway economy.
The big problems, of course, are how we take account of past responsibility for the carbon in the atmosphere, how we balance aggregate national emissions and per capita figures – China leads in the first category; the US, Australia, and Canada are the biggest culprits in the second – and how we manage technology transfer from developed to emerging and poor economies.
Ideas for carbon taxes run into resistance everywhere.
The former is good news for China’s carbon footprint, the latter for its social stability.
But a closer look at the global energy system, together with a more refined understanding of the emissions challenge, reveals that fossil fuels will likely remain dominant throughout this century – meaning that carbon capture and storage (CCS) may well be the critical technology for mitigating climate change.
Kaya calculated CO2 emissions by multiplying total population by per capita GDP, energy efficiency (energy use per unit of GDP), and carbon intensity (CO2 per unit of energy).
Given the impracticality of winning support for proposals based on population management or limits on individual wealth, analyses using the Kaya Identity tend to bypass the first two terms, leaving energy efficiency and carbon intensity as the most important determinants of total emissions.
Plants absorb carbon dioxide and produce oxygen, thereby providing the air we breathe and helping to regulate the climate.
Droughts and heat waves are a harbinger of our future, carbon cuts are needed now more than ever, and yet meaningful policies have not been enacted.
The cause is an unprecedented switch to natural gas, which emits 45% less carbon per energy unit.
And, while a flagging economy may explain a small portion of the drop in US carbon emissions, the EIA emphasizes that the major explanation is natural gas.
Indeed, US carbon emissions have dropped some 20% per capita, and are now at their lowest level since Dwight D. Eisenhower left the White House in 1961.
To put that number in perspective, it is about twice the total effect of the Kyoto Protocol on carbon emissions in the rest of the world, including the European Union.
This flies in the face of conventional thinking, which continues to claim that mandating carbon reductions – through cap-and-trade or a carbon tax – is the only way to combat climate change.
Estimates suggest that using carbon taxes to achieve a further 330 Mt CO2 reduction in the EU would cost $250 billion per year.
The amazing truth is that fracking has succeeded where Kyoto and carbon taxes have failed.
What little chance there was of the US backing any global plan to limit or tax carbon emissions has disappeared.
At the same time, the UK Parliament has approved stringent new measures to reduce carbon emissions by 2020, with the biggest CO2 cuts by far to come from an increase of more than 800% in offshore wind power over the next seven years.
Gas emits less than half the CO2 per kWh produced, and it emits much lower amounts of other pollutants like NOx, SO2, black carbon, CO, mercury, and particulates.
If the UK sold its shale gas both domestically and abroad to replace coal, it could reduce local air pollution significantly and reduce global carbon emissions by 170Mt, or more than a third of UK carbon emissions.
The London School of Economics’ Grantham Research Institute has analyzed the submissions made by all 154 countries and concluded that even if they are all implemented, global carbon emissions will rise from their current level of 50 billion tons per year to 55-60 billion tons by 2030.
But, to have even a 50% chance of keeping to the 2ºC limit, annual carbon emissions need to come down to 36 billion tons.
To encourage governments to act in concert, it is essential to work toward a system of carbon pricing that is both straightforward and transparent.
We propose a carbon “price-and-rebate” mechanism, which simultaneously sets a price on emissions above a certain threshold and defines how the revenues raised should be used.
