CarbFix Project: World’s first negative emissions carbon-capture plant begins operations in Iceland

The world’s first negative emissions plant under the CarbFix Project to turn atmospheric carbon dioxide (CO2) into stone has begun operations in Hellisheidi, Iceland. It is intended to lock away carbon dioxide by reacting it with basaltic rocks. Work on the project began in 2007.

CarbFix Project

In it, the CO2 is captured from ambient air, bound to water, and sent to more than 700 meters underground. There, the CO2 reacts with the basaltic bedrock using enhanced weathering process and forms solid minerals, creating a permanent storage solution.
Currently, the system captures only 50 metric tons CO2, each year, about same emitted by a single US household. It can remove an estimated 50 metric tons of CO2 from the air in a year. It pumps the collected gas deep into the island’s volcanic bedrock, where it reacts with basalt and essentially turns into limestone.

Volcanic carbon dioxide drove ancient global warming: Study

According to study conducted by researchers from University of Southampton, UK, extreme global warming event 56 million years ago was driven by massive carbon dioxide (CO2) emissions from volcanoes, during formation of North Atlantic Ocean.
They had used combination of new geochemical measurements and novel global climate modelling to show that Palaeocene-Eocene Thermal Maximum (PETM) was associated with rapid doubling of atmospheric CO2 in less than 25 thousand years because of CO2 emissions from volcanoes.

Key Facts

The PETM was most rapid and extreme natural global warming event of last 66 million years. It had lasted for around 150 thousand years and increased global temperatures by at least 5 degrees Celsius. Its period coincided with the formation of massive ‘flood basalts’ — large stretches of ocean floor coated in lava, resulting from of a series of huge eruptions.
Earlier it was suggested that PETM event was caused by injection of CO2 into ocean and atmosphere, but ultimate trigger source of CO2 was not known. Now researchers believe that, the CO2 was released during land drifts, separating Greenland from north-western Europe, thereby creating North Atlantic Ocean.
During this time, more than 10,000 petagrammes of CO2 was released predominantly from volcanic source. This is a vast amount of CO2, 30 times larger than all fossil fuels burned to date and equivalent to all current conventional and unconventional fossil fuel reserves.

China launches satellite to monitor global gas emissions

China has launched a 620-kg satellite TanSat into orbit to monitor global carbon dioxide levels to understand climate change. The satellite was put into orbit by Long March-2D rocket from Jiuquan Satellite Launch Centre located in Gobi Desert. Apart from TanSat satellite, a high-resolution micro-nano satellite and two spectrum micro-nano satellites for agricultural and forestry monitoring were also launched. The satellite placed in the sun-synchronous orbit will monitor the concentration, distribution and flow of carbon dioxide (CO2) in the atmosphere. It will monitor global carbon dioxide levels every 16 days accurate to atleast 4 parts per million (ppm). With this launch, China has become the third country after Japan and the US to monitor greenhouse gases with the help of its own satellite.

Underwater Robot gives rare glimpse beneath Antarctic sea ice

Remotely Operated Vehicle sent down by scientists of the Australian Antarctic Division (AAD) has captured a rare glimpse beneath the Antarctic sea ice through a small hole drilled in the ice. It also recorded the acidity, oxygen, salinity and temperature of the seawater in the area. The footage captured by the robot reveals a productive, colourful and dynamic habitat filled with a wide variety of biodiversity like coconut-shaped sponges, dandelion-like worms, pink algae and spidery starfish etc. These species were found to survive in water that is -1.5 degrees Celsius all round the year and covered in 1.5 metres of sea ice for almost ten months of the year. Scientists in Antarctica are working to understand the impact of acidification on Southern Ocean sea-floor communities with increase in carbon dioxide emissions.

About quarter of the Carbon dioxide emitted into the atmosphere is absorbed by the ocean. Carbon dioxide is more soluble in cold and polar water and will increase the acidity of the sea water.

3% rise in Global Carbon Dioxide Emissions in 2011

As per the report “Trends in global CO2 emissions”, there is a 3% surge in the global carbon dioxide (CO2) emission in 2011. The 3 % increase took the total amount of CO2 in air at an all-time high of 34 billion tonnes. The report was published by the European Commission’s Joint Research Centre (JRC) and the Netherlands Environmental Assessment Agency (PBL).

As per the the report:

· The U.S. emits 17.3 tones per capita of CO2 . It is still one of the top emitters.

· China with an average of 7.2 tonnes per capita emission saw an increase by 9% in CO2 emission.

· The per capita emission of 27-nation European Union was 7.5 tonnes.

· The 34-nation Organisation for Economic Co-operation and Development (OECD) countries was responsible for only 1/3rd of global CO2 emissions in 2011.

Canada quits Kyoto

  • Complaining that Kyoto Protocol does not cover the world’s two largest emitters, the United States and China, and therefore cannot work, Canada has quit the Kyoto Protocol.
  • The Protocol originally covered countries generating less than 30 per cent of global emissions and now it covered less than only 13 per cent and that number was only shrinking.
  • Canada’s withdrawal comes at a time when it has increasingly gained the reputation of a climate “renegade” that has encouraged the rampant use of polluting energy platforms. For example, oil sands production, one of the most polluting forms of oil extraction, is at the heart of Canada’s discussion with the U.S. regarding the now-infamous Keystone Pipeline.

India agrees to legally binding emission cuts in Durban climate deal

  • India at Durban has for the first time agreed to binding emission cuts, with all other major emitters, but the quantity of cuts would be based on equity. The 194 countries have agreed on a roadmap for a 2015 accord that will, for the first time, legally force all major emitters of greenhouse gases to reduce their emissions. Thus, India has now three years to decide how much carbon emissions reductions it would be willing to take after 2020. However, the new emission reduction regime will be based on equity. A country like India which has much lower emissions than China would be given a lower reduction target.
  • India had so far refused to agree to emission cuts till its per capita emissions rise above average per capita emissions of the developed world.
  • The US which had opted out of the Kyoto Protocol has now also come on board.
  • The parties would develop a new protocol, another legal instrument or agreed outcome with legal force that would be applicable under the UN climate convention. The new treaty would come into force by 2020.
  • The countries will begin negotiations for new deal that covers all countries next year. They have agreed to the second commitment period under Kyoto Protocol, the only legally-binding treaty for cutting greenhouse gas emissions.
  • Kyoto Protocol treaty, which expires next year, mandates the 37 industrialised nations and the EU to cut carbon emissions to five per cent below the 1990 levels by 2012. But it exempts developing countries like China and India from any meeting any targets. The US had chosen to remain out of the Kyoto Protocol.

Delhi Metro: First Train in world to earn ` 47cr carbon credit points

Delhi Metro has become the first such railway project in the world to get carbon credits from UN’s Clean Development Mechanism (CDM) under the Kyoto Protocol, for helping in reduction of greenhouse emissions. Delhi Metro Rail Corporation (DMRC) has helped in reduction in emission of harmful gases into the city’s atmosphere. In the process, it has earned carbon credits worth about Rs 47 crore annually for the next seven years. “With the increase in number of passengers, this figure shall increase. According to the UN, Delhi Metro has helped in reducing pollution levels in the city by 6.3 lakh tonnes every year, thereby helping in mitigating impacts of global warming. “Today, about 18 lakh people travel by Delhi Metro that is completely non-polluting and environment friendly. But for the Metro, these people would have travelled by cars, buses, two/three wheelers, which would have resulted in GHG emission.
