Planning and Financing Low-Carbon, Livable Cities   Leave a comment

Planning and Financing Low-Carbon, Livable Cities.

STORY HIGHLIGHTS
  • World Bank Group President Jim Yong Kim announced a groundbreaking new initiative to reach 300 cities in developing countries over four years to help them plan for a low-carbon future and get the needed finance flowing.
  • An estimated 6.2 billion people – two-thirds of the world’s population – will be living in cities by 2050.
  • Cities already account for about two-thirds of the world’s energy consumption and about 70 percent of greenhouse gas emissions. A low-carbon development path could help them cut global greenhouse gas emissions by 30 percent.

Rethinking Carbon Dioxide: From a Pollutant to an Asset by Marc Gunther: Yale Environment 360   Leave a comment

“Carbon dioxide removal, or CDR, is sometimes seen as a subset of geoengineering — deliberate, planetary-scale actions to cool the Earth — but it’s actually quite different. Geoengineering strategies are risky, imperfect, Carbon dioxide removal is more akin to recycling waste than to playing God with nature. controversial, and difficult to govern. The most-discussed geoengineering technology, solar radiation management, alleviates a symptom of the climate problem (warmer temperatures) but does nothing to address the cause (rising atmospheric concentrations of CO2). What’s more, geoengineering as a climate response is stuck because governments have declined to provide more than token funds for research, and there’s no business model to support it.

 

Carbon dioxide removal, by contrast, targets the root cause of global warming. It doesn’t create global risks. It’s being financed by the private market, and it’s more akin to recycling waste than to playing God with the weather.

Despite widespread skepticism in the scientific community, three startup companies are betting that they can make money by recycling CO2, and thereby cool an overheating planet.”

Climate Change Trends: Carbon Emissions Giants : NPR   Leave a comment

“Right now, 10 countries — including the U.S., China and Russia — are responsible for 80 percent of the world’s carbon dioxide emissions. The United States is the world’s second largest emitter (China ranks no. 1), sending around 5.8 million metric tons of CO2 into the atmosphere a year. That’s the equivalent to a year’s worth of greenhouse gas emissions from 1.1 billion average passenger vehicles. Below, a look at today’s big CO2 emitters — and projected emissions giants in 2030.”

Canada, U.S. must have similar policies on carbon, U.S. ambassador says   Leave a comment

“Finding a way to limit carbon emissions will be a major issue for Canada-U.S. relations, and the two countries can’t be too far apart in their policies, says U.S. Ambassador David Jacobson.

Putting a price on carbon is one way to slow down greenhouse gas emissions but the price set by either country could influence where investment decisions are made, Jacobson told The Journal’s editorial board Wednesday.

It’s important that national policies do not give one country a competitive advantage, he said, “so people won’t make economic decisions based on the differences.”

“You don’t want to have a race to the bottom.”

While the issue of greenhouse gas emissions is “the single hardest issue” for the two countries to work through, Jacobson said he’s confident in the end the national policies will work in “sync.” President Barack Obama’s administration will not bring proposals forward this term, he said.”

Cities can be carbon sinks too: study › News in Science ABC Science   Leave a comment

The concept that greenspace and urban_forests can act as a carbon sink in cities is helpful to consider . Any promotion of greenspace and additional tree plantings in cities should be encouraged.

“Urban sinks are not by themselves a solution to the billions of tonnes of carbon emitted globally, but can help mitigate their impact, especially if gardeners grow trees, which absorb far more CO2 than grass and shrubs, she says.In the case of Leicester, most of the publicly-owned or -managed land in the city comprises lawns. But if just 10 per cent of this land were planted with trees, the citys carbon storage would leap by 12 per cent.”If more trees are planted in urban areas for their carbon storage value, they must be the right kind of tree planted in the right place so that they have a long, productive lifespan, and when trees die they should be replaced,” says Davies.”

Northwest Forest Plan has unintended benefit – carbon sequestration | e! Science News   Leave a comment

A  fifth major benefit of sustainable forest management : carbon sequestration.

“Forests provide many services, such as habitat protection, recreation, water purification, and wood production,” he said. “Carbon sequestration has now been added to that list. And our approach can provide the kind of spatially and temporally explicit data that will help evaluate the potential trade-offs associated with management activities.”
