The real social cost of carbon: $220 per ton, report finds | GreenBiz
How much does each ton of carbon dioxide released into the atmosphere really cost us? Whether you're a corporate executive penciling out the costs of new emissions-reduction strategies or a government regulator evaluating the feasibility of a carbon tax, the idea of putting a concrete price on carbon permeates the field of sustainability. Now, a new paper by two Stanford University researchers (PDF) contends that current government estimates of the "social cost of carbon" — a key metric of the economic damage caused by climate change used in cost-benefit analysis of regulations — could fall woefully short of reality. The researchers contend in the paper published in the journal Nature that the social cost of carbon on the global economy is actually about $220 for each ton of carbon dioxide emitted, a far cry from the $37 calculated by the U.S. government. Calculating social costs When it comes to whether the new data actually will shift government procedure, officials at the U.S.
Mission & Vision | Carbon War Room
The Carbon War Room accelerates the adoption of business solutions that reduce carbon emissions at gigaton scale and advance the low-carbon economy. Carbon War Room focuses on the market barriers that reinforce the status quo and prevent capital from flowing to sustainable solutions with compelling returns. Often, strong policy is a necessary but insufficient condition, and technology is not the bottleneck: Capital has to flow to solutions in a well-functioning market-place. Our vision is a world where over $1trillion invested in climate change solutions is an annual occurrence, not a historic milestone (Bloomberg New Energy Finance).

About CDM
The allows emission-reduction projects in developing countries to earn certified emission reduction (CER) credits, each equivalent to one tonne of CO2. These CERs can be traded and sold, and used by industrialized countries to a meet a part of their emission reduction targets under the Kyoto Protocol. The mechanism stimulates sustainable development and emission reductions, while giving industrialized countries some flexibility in how they meet their emission reduction limitation targets. The CDM is the main source of income for the UNFCCC Adaptation Fund, which was established to finance adaptation projects and programmes in developing country Parties to the Kyoto Protocol that are particularly vulnerable to the adverse effects of climate change.

Technology
Every day, plants and microorganisms use greenhouse gases to make useful materials, from carbon dioxide-capturing redwood trees and coral reefs to deep sea methane-capturing hydrothermal vent ecosystems. Inspired by these carbon-capturing processes in nature, Newlight has developed, patented, and commercialized a carbon capture technology that combines air with methane emissions to produce a plastic material called AirCarbon. By weight, in its most basic form, AirCarbon is approximately 40% oxygen from air and 60% carbon and hydrogen from captured carbon emissions. The AirCarbon production process begins with concentrated methane-based carbon emissions that would otherwise become a part of the air, rather than fossil fuels that would otherwise remain underground, including air-bound methane emissions generated from farms, water treatment plants, landfills, and energy facilities. Products that harness greenhouse gas emissions as a resource, reduce cost, and improve the world.
Carbon Dioxide or Solar Forcing? | ScienceBits
By: Nir J. Shaviv Natural or Anthropogenic? Which mechanism is responsible for global warming over the 20th century? According to the common perception, the temperature over the 20th century has been warming, and it is mostly anthropogenic in origin, with greenhouse gases (GHGs) being the dominant driver. Others, usually called "skeptics", challenge this view and instead claim that the temperature variations are all part of natural variability. Like many others, I was personally sure that CO2 is the bad culprit in the story of global warming. What is the evidence for an anthropogenic effect? The first question we wish to address is whether there is actual evidence indicating that greenhouse gases (GHGs) are responsible for most of the warming. The truth is that there is no real evidence for this link. The IPCC writes about fingerprinting the anthropogenic causes. But in itself it is not proof that GHGs are the major cause.

Key trends in air quality monitoring and management | Smart Cities Dive
Editor's Note: This piece was written by Ryan Citron, a research analyst in Navigant Research's Transportation Efficiencies and Building Innovations program. The opinions represented in this piece are independent of Smart Cities Dive's views. The growth of urban air pollution is one of the most serious indicators of the impact of global urbanization on the environment and human health. If city officials are to fully understand and improve air quality conditions, pollutants must be accurately measured, monitored and managed. The rise of low cost sensor networks Currently, most cities measure air pollution using a collection of large environmental monitoring stations. Sensor networks are currently taking the form of a supplement to traditional measurement stations. Get smart cities news like this in your inbox daily. While sensor networks offer great promise for lower cost and quickly deployed environmental monitoring, a number of challenges need to be addressed. Crowdsourcing
