Sentences with phrase «just coal emissions»

To derive a global budget for just coal emissions, we applied coal's proportion of fuel combustion (40 %) to both the precautionary global fossil fuel budget (500GtCO2) to have an 80 % of limiting global warming to 2 °C, and the optimistic budget of 900GtCO2.

Putting the brakes on CO2 emissions has to mean replacing coal as a power source, unless emissions from coal can be sequestered safely and efficiently, which seems unlikely just now, given that research has not yielded any progress.

Just a quick note to those seeking a rapid decline in emissions of greenhouse gases (and other pollution) from coal combustion: The challenge, in a world with rising populations and energy appetites, is getting harder by the day.

Through appropriate building design, behavioural change and demand management (this does not mean living like a cave - man, just using resources efficiently) and appropriate matching of energy source with demand (i.e using solar radiation, not brown coal fired electricity for water heating), it is possible to eliminate these emissions completely.

While those emissions have continued to decline in the West, returns, from a brightening standpoint, have diminished, just as coal combustion ramped up in Asia.

Emission growth has slowed only because certain forms of emission have been easy to phase out and energy efficiency has become a priority for environmental reasons, but if you think coal, oil and deforestation will just go away by themselves, you are dreaming.

With about 90 % of the carbon emissions from our electricity sector coming from coal fired power stations, Australia will need to look beyond just coal towards the full spectrum of available energy solutions.

Antiquated so - called subcritical coal - fired power plants have an emissions intensity of just under 1,000 kg of CO2 per megawatt - hour.

To take just one example, the agency could decide that older coal plants only have to make efficiency upgrades to curb pollution — in which case a modest cut in emissions is about the best that could be expected.

However, the National Energy Technical Laboratory's (or NETL) just released «Life Cycle GHG Perspective on Exporting LNG from the U.S.» found that there are 50 percent more emissions from the natural gas export supply chain compared to coal's supply chain, offsetting the gains due to lower pollution from combustion.

«There is no great urgency, things will just roll nicely on, and we continue to approve new coal mines,» Mr Cousins said, adding the Stockholm report revealed how little time was left to take serious steps to cut emissions.

That means voting out governments that won't close down coal plants and cut absolute emissions from the oil sands, not just insisting that governments say nice things about the issue while remaining basically inactive about it.
