CO2 emissions from fossil fuel combustion and cement production reached 9.7 gigatons of carbon (GtC) in 2012 and may reach 9.9 GtC in 2013. Coal remains a major driver of CO2 emissions, accounting for 54 percent of the emissions increase in 2012. Fossil fuel combustion, together with deforestation and land use change, has pushed the … Continue reading Record High for Global Greenhouse Gas Emissions

Negotiating Climate Change as if Development Really Mattered
Worldwatch Climate and Energy Director Alexander Ochs emphasizes the need to focus on what can be won, both in terms of climate and development, through the decarbonization of human activities. Over the past twenty years, climate negotiations have been dominated by concerns that addressing global warming is anti-business and onerous to future development. The insufficient … Continue reading Negotiating Climate Change as if Development Really Mattered

UN conference overlooks the rising power of wind energy and other renewables
Another annual United Nations conference on climate change has ended and international negotiators once again failed to agree to a new treaty on reducing global greenhouse gas emissions from burning fossil fuels. Countries gathering the past two weeks in Warsaw made earnest speeches, said they understood the challenge that humans face from increasing levels of … Continue reading UN conference overlooks the rising power of wind energy and other renewables

Climate Change Driving Weather off the Charts
Meteorologists are calling the typhoon that slammed into the Philippines with 195-mile-an-hour winds on November 8, 2013, the most powerful tropical storm to make landfall on record. Super Typhoon Haiyan had gusts reaching 235 miles per hour and a storm surge swelling as high as 20 feet, so the destruction it left behind matched that … Continue reading Climate Change Driving Weather off the Charts

Look out for that turbine! Climate sceptics are the real Chicken Littles
Several Australian corporate figures have recently disparaged climate scientists. First, former banker David Murray questioned the integrity of climate scientists on national TV. Casting such aspersions on scientists follows the precedent set by the tobacco industry, which referred to medical researchers as an

Crystalline Silicon and Thin Film Photovoltaic Results
professional essay Over the last 30 years, hundreds of life cycle assessments (LCAs) have been conducted and published for a variety of residential and utility-scale solar photovoltaic (PV) systems with wide-ranging results. The inconsistencies in these results can be attributed to the technologies evaluated

Wind Energy Results
To better understand the state of knowledge of greenhouse gas (GHG) emissions from utility-scale wind power systems, NREL developed and applied a systematic approach to review life cycle assessment literature, identify sources of variability and, where possible, reduce variability in GHG emissions estimates through a meta-analytical process called “harmonization.” Over the last 30 years, several … Continue reading Wind Energy Results

Carbon dioxide emissions from burning fossil fuels in the United States peaked at more than 1.6 billion tons of carbon in 2007. Since then they have fallen 11 percent, dropping to over 1.4 billion tons in 2013, according to estimates from the U.S. Energy Information Administration. Emissions shrank rapidly during the recession, then bounced back … Continue reading U.S. Carbon Dioxide Emissions Down 11 Percent Since 2007

Significant, concerted action is now required to stop the continued growth of toxic greenhouse gases caused by burning fossil fuels, says the latest Intergovernmental Panel on Climate Change (IPCC) report on global warming. Atmospheric concentrations of carbon dioxide (CO2) and other greenhouse gases have increased to levels unprecedented in at least the last 800,000 years, … Continue reading IPCC: fossil fuels must remain in ground to avoid climate catastrophe

The Intergovernmental Panel on Climate Change (IPCC) has confirmed that the human influence on climate change is undeniable and has urged governments to take action. The IPCC’s fifth assessment report, Climate Change 2013: The Physical Science Basis, details projections of climate change based on four scenarios of future greenhouse gas concentrations and aerosols, for a … Continue reading IPCC: Humans are to blame for climate change

Ever since the 2008 financial crisis and subsequent economic malaise, corporate sustainability has lost a bit of its luster as companies strayed away from “green” messaging and more toward job creation and technological innovation. Even GE’s Jeff Immelt, at one time the leader of corporate green converts, said in 2011 he regretted the company’s green … Continue reading CO2 Emissions at the World

Climate Change as a Threat Multiplier in Syria
Among the factors that have driven the Syrian people to rise up against the Assad regime was a climate-change-related drought that caused a famine, according to ex-U.S. State Department advisor William Polk. “Syria is and has always been a complex society,” Polk wrote recently in describing the conflict’s context for The Atlantic. But it “has … Continue reading Climate Change as a Threat Multiplier in Syria

Increasing global emissions of carbon dioxide (CO2), a heat-trapping gas, are pushing the world into dangerous territory, closing the window of time to avert the worst consequences of higher temperatures, such as melting ice and rising seas. Since the dawn of the Industrial Revolution, carbon emissions from burning fossil fuels have grown exponentially. Despite wide … Continue reading Carbon Emissions: Fossil Fuel Use Pushes Carbon Dioxide Emissions into Dangerous Territory

On their second time around, European MEP’s yesterday voted in favour of ‘backloading’. This means that the number of permits to pollute released under the Emissions Trading System (ETS) will be temporarily reduced by 900 million tonnes of carbon. This will increase the cost of carbon to industry and create an incentive to pollute less. … Continue reading ETS backloading cautiously welcomed as first step towards reviving carbon market

The world is not on track to reach its goal of limiting global temperature increase to 2°C, warned the International Energy Agency (IEA) on Monday. Highlighting the need for intensive action in the energy sector before 2020, the IEA noted that the energy sector accounts for about two-thirds of global greenhouse gas emissions from burning … Continue reading Phase out fossil fuel subsidies and limit use of coal-fired plants, IEA says
