Turning greenhouse gases into plastic

Cradle to Cradle packaging is becoming a reality as according to Cleantechies : “ It sounds like something straight out of a science fiction novel. Capturing carbon from the air and turning it back into plastic. But thankfully it’s already a reality. ” Coined AirCarbon, the biodegradable PHA-based plastic material is made from air and greenhouse gases … Read more

Hydrofluorocarbons could be phased out soon

HydrofluorocarbonsAccording to the White House website : “ the United States and China will work together and with other countries to use the expertise and institutions of the Montreal Protocol to phase down the consumption and production of hydrofluorocarbons “

Now that’s some good news are HFCs are very potent greenhouse gases. As Bloomberg noted : ” HFCs make up about 1 percent of greenhouse gases and may account for more than 20 percent by 2050.

As Grist notes, the European Union is also pushing into this direction. This could mean an agreement on HFCs could be reached quite soon.

IEA presents four energy policies to keep Earth cool

IEA Redrawing the energy climate mapAs I noted last week, the prestigious International Energy Agency reported that despite some emission reductions from the United States and Europe, the world keeps on spewing more and more gigatonnes of greenhouse gases.

Luckily, the IEA proposes in its latest report four energy policies that would cut by eight percent the 2020 emissions compared to a business as usual scenario. This would amount to 3.1 Gt CO2 equivalent.

While these actions are not exactly what the worlds need to keep its climate as cool as it should be, they could be done at no net economic cost.

South Africa to tax carbon by 2015

Will we have a global carbon tax by 2015 ? Even if it is way too early to tell, here are some news in that direction. After China, South Africa plans to enact a carbon tax by this year. Reuters, Bloomberg and All Africa brings us more details. The tax would be of around $14 … Read more

A great infographic on climate change

I already wrote a few times on infographics and how they can be amazing. Indeed, with some of them, a single image is indeed worth a thousand words ( or more ). Here is the latest example I found. It’s explains exactly what has to be done regarding carbon dioxide emissions. And what would be … Read more

Further evidence on how climate change is VERY serious

Parched earth because of climate changeReaders be advised, this post is a collection of the latest climate change news I have collected the past week. And to tell the truth, the more science on global warming is published, the more alarming it is.

First thing first, concentrations of carbon dioxide have increased in 2012 by no less than 2.67 parts per million since 2011 to total just under 395 parts per million (ppm). While this doesn’t look much, it is still the second-greatest annual rise in CO2.

This huge increase questions our willingness to prevent the worse from taking place. Even if we are acting on climate change, we aren’t doing enough.

A 1.5°C temperature rise could be game over for our civilization

Oooops ! According to Cleantechies, a 1.5°C temperature rise ” could unleash more than 1,000 gigatons of carbon and methane currently trapped beneath Siberian permafrost and accelerate global climate change. “ 1.5°C is considered as the low level of potential climate warming to date. This is even more worrying as such quantities of greenhouse gases … Read more

More on the Chinese carbon tax

Tonnes and tonnes of coal in ChinaA year ago I was relating how China, the largest greenhouse gases emitter, was willing to tax carbon by 2015. It seems the local government is pretty serious about it as last week’s news show.

To the Clean Revolution : ” China’s Finance Ministry has announced a new set of green taxation policies, including a tax on carbon which will help curb emissions, improve air quality and incentivize the clean energy industry. “

As China consumes almost half of the coal in the world, it’s to be hoped that this carbon tax will change things. But will the low level be enough ?

Soot’s underestimated role in climate change

Soot, aka black carbonAccording to the most comprehensive research on the subject, soot – also known as black carbon – may have a significantly higher role in climate change than previously estimated.

According to a BBC article quoting the study : ” (soot) dark particles are having a warming effect approximately two thirds that of carbon dioxide, and greater than methane. “

Tackling its emissions – which come mostly from wood and coal burning as well as diesel engines in developed countries – would be easy to tackle.

European emissions keep on decreasing, again

After the summer break, I am back on Cleantechies with good news as it is to report that European greenhouse gases emissions have decreased by 3.5 percent between 2010 and 2011. Here is a part of the introduction : ” The EU-15 emissions are now 14.1 % below the base-year level under the Kyoto Protocol. … Read more

A/C may contribute significantly to global warming

As the planet is warming and as more and more people can afford it, air conditioning is becoming more and more widespread. This wouldn’t be a problem if A/C weren’t emitting greenhouse gases. To the NY Times : ” The leading scientists have just calculated that if all the equipment entering the world market uses … Read more

Chinese emissions are 20% higher than expected

Two different news regarding China hit the twitterverse on the same day last week. First, the bad one : The People’s Republic’s greenhouse gases emissions may have been underestimated by as much as 20 percent.

This huge difference – as much as the annual emissions of Japan, or 1.4 Gt of CO2 –  can be explained by the fact that there are ” inconsistencies of coal consumption between national and provincial statistics “

All this has a lot of repercussions for everyone as it makes climate change mitigation even harder than it was for both scientists and internatinonal negotiation.
