Countries are progressing too slowly on green growth, says OECD (downtoearth)

Many countries have become more efficient in using natural resources and the services provided by the environment, generating more economic output per unit of carbon emitted and of energy or raw materials consumed. Yet progress is too slow, and if emissions embodied in international trade are included, advances in environmental productivity are more modest, a new OECD report shows.

Green Growth Indicators 2017 uses a range of indicators covering everything from land use to CO2 productivity and innovation to show where 46 countries rank on balancing economic growth with environmental pressures over 1990 to 2015. It finds that Denmark, Estonia, the United Kingdom, Italy and the Slovak Republic have made the most progress on green growth since 2000.

The report shows that no country is performing well on all green growth dimensions and most of the countries studied are yet to fully disconnect economic growth from fossil fuel use and pollutant emissions. Progress has often been insufficient to preserve the natural asset base or relieve pressure on ecosystems and on natural environmental services such as water purification and climate regulation.

“While there are signs of greening growth, most countries show progress on just one or two fronts and little on the others,” said OECD Environment Director Simon Upton. “We need much greater efforts across the board if we are to safeguard natural assets, reduce our collective environmental footprint and sever the link between growth and environmental pressures.”

The report shows that since the 1990s all OECD and G20 countries have increased their overall environmentally-adjusted productivity – a way of measuring economic productivity that accounts for pressures like pollution and the use of natural resources.

Carbon productivity (GDP per unit of CO2 emitted) has improved, with half of the 35 OECD members “decoupling” emissions from growth, meaning emissions no longer rise in tandem with growth. Switzerland and Sweden showed the highest level of carbon productivity, while the Slovak Republic, Latvia and Poland all reduced CO2 emissions as GDP rose.

A more nuanced picture emerges when trade flows are factored in and emissions are considered from the perspective of final demand. Most OECD countries are net importers of CO2 emissions, so when the CO2 emitted during production stages of goods or services abroad is included, only 12 OECD countries decoupled emissions from GDP.

To generate USD 1,000 of GDP, OECD countries consume around 420 kg of non-energy materials and 111 kg of energy products, on average, and emit around 260 kg of CO2.

Other key findings in the report

Of the 46 countries examined, Iceland, Costa Rica and Sweden have the highest share of renewables in their energy mix. The BRIICS have a higher average share of renewables at 14.8% than OECD countries at 9.6%, but the share has dropped in the BRIICS since 1990 while it has risen in the OECD area.
China and the US extract the most non-energy raw materials followed by India and Brazil (mostly biomass), and South Africa and Canada (mostly metals). Globally, material extraction has risen more than 200% since 1980, due largely to a surge in mining of non-metallic minerals. The Netherlands, the UK and Japan score highest in material productivity.
Urban areas are growing rapidly, even in some already highly urbanised countries, and across the OECD built-up areas are growing faster than populations. Buildings cover 30% more land now than in 1990. Globally, an area the size of the UK has been converted to buildings since 1990. Building over land means a loss of agricultural terrain and biodiversity and has negative effects on the water cycle.
Air pollution remains dangerously high. Less than one in three OECD countries meet WHO air quality guidelines for fine particulate matter and pollution levels are high and rising in China and India.
A surge in innovation and green technologies in the early 2000s boosted productivity and growth, but since 2011 inventive activity has slowed in all major technological areas related to the environment. About 90% of green technologies originate in OECD countries, but the contributions of China and India are rising fast.

NGT terminates chairmen of pollution control boards in 10 states (downtoearth,)

Cracking the whip on 10 State Pollution Control Boards (SPCBs) for ad-hoc appointments, the National Green Tribunal has ordered the termination of Chairpersons of these regulatory authorities. The concerned states are Himachal Pradesh, Sikkim, Tamil Nadu, Uttarakhand, Kerala, Rajasthan, Telangana, Haryana, Maharashtra and Manipur. The order was given last week by the principal bench of the NGT, chaired by Justice Swatanter Kumar. The recent order of June 8, 2017, comes as a follow-up to an NGT judgment given in August 2016. In that judgment, the NGT had issued directions on appointments of Chairmen and Member Secretaries of the SPCBs, emphasising on crucial roles they have in pollution control and abatement. It then specified required qualifications as well as tenure of the authorities. States were required to act on the orders within three months and frame Rules for appointment [See Box: Highlights of the NGT judgment of 2016 on criteria for SPCB chairperson appointment]. Having

High dose of Vitamin C and B3 can kill colon cancer cells: study (downtoearth)

In a first, a team of researchers has found that high doses of Vitamin C and niacin or Vitamin B3 can kill cancer stem cells. A study published in Cell Biology International showed the opposing effects of low and high dose of vitamin C and vitamin B3 on colon cancer stem cells. Led by Bipasha Bose and Sudheer Shenoy, the team found that while low doses (5-25 micromolar) of Vitamin C and B3 proliferate colon cancer stem cells, high doses (100 to 1,000 micromolar) killed cancer stem cells. Such high doses of vitamins can only be achieved through intravenous injections in colon cancer patients. The third leading cause of cancer deaths worldwide, colon cancer can be prevented by an intake of dietary fibre and lifestyle changes. While the next step of the researchers is to delineate the mechanisms involved in such opposing effects, they also hope to establish a therapeutic dose of Vitamin C and B3 for colon cancer stem cell therapy. “If the therapeutic dose gets validated under in vivo

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”. The Supreme Court on Friday came close to ordering the government not to deport the Rohingya. It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests. The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach i
