Canada To Reduce HFC Emissions By 85% By 2036

HFC (hydrofluorocarbon) emissions contribute to climate change, and Canada and many other nations are taking a stand to reduce their emissions by 85% in the next 20 years. HFCs are commonly found in refrigerators, air conditioners, foam products, and other items world-wide. Current global HFC emissions are the equivalent of approximately 1 billion tons of carbon dioxide annually. That is the same as emissions from nearly 300 coal-fired power plants or over 200 million passenger vehicles driven for one year, and…

Masdar City: A Test Case for Sustainable Urban Living

Sweltering in the hot desert sun, Masdar City sits under a global microscope at the nexus of rising clean technology and the development of sustainable urban life in the glaring light of climate change. Conceived on a zero-moisture stretch of barren desert sand in Abu Dhabi, UAE, the zero-carbon, zero-waste settlement of Masdar City has diligently sustained itself through every struggle and step of progress. Masdar City: A Living, Striving Test Case for Earth’s Future As the warming effects of…

Blocks – The ABCs of Green Building Materials

Blocks used for residential and commercial construction employ a wide variety of green building materials in their composition. The most popular and commonly used is the standard hollow concrete block, but there are many variations in shape, weight, and composition. Sand, cement, gravel, and water are the most commonly used elements in blocks, but there is a wide variety in the mix of materials used. This latest article in our series, the ABCs of Green Building Materials, explores the various…

What is LEED? – Energy and Atmosphere

This is the fifth post in a series on the LEED green building rating system. The first post provided an Introduction to LEED, the second looked at the Sustainable Sites credit category, the third at the Location and Transportation credits, and the fourth at Water Efficiency.   Energy and Atmosphere Improving energy efficiency is one of the easiest ways to save money and improve the sustainability of a building. Therefore almost a third of the points available in LEED are found…

Climate Change at the Movies

This is an interesting study concerning how people are influenced about real or entertaining issues on subject matter such as climate change. Since we have recently published articles specifically related to facts on climate change it has been interesting watching the number of deniers who penned their two-cents-worth, arguing that the debate on climate change is no more than a liberal-driven political issue. I think we should always have facts in the proper place, whether it involves entertainment or political debate.…

Reducing Emissions the Primary Way to Fight Climate Change Reports UCLA-Led Study

Climate engineering won’t sufficiently stem global warming Forget about positioning giant mirrors in space to reduce the amount of sunlight being trapped in the earth’s atmosphere or seeding clouds to reduce the amount of light entering earth’s atmosphere. Those approaches to climate engineering aren’t likely to be effective or practical in slowing global warming. A new report by professors from UCLA and five other universities concludes that there’s no way around it: We have to cut down the amount of…

Life cycle assessment

What is Life Cycle Assessment?

Life cycle assessment (LCA) looks at the environmental impacts of a building material over the entire life of the material, from extraction to disposal. LCA attempts to quantify these impacts for the purpose of comparing materials or buildings. What is measured? LCA is a scientific study of the environmental inputs and outputs to a building material, product, or a whole building throughout its life. Several environmental effects are studied in each assessment, including: Use of fossil fuels Use of non-renewable…

Carbon Markets Cut Emissions 17x Cheaper Than Subsidies

[repostus]Carbon Markets Cut Emissions 17x Cheaper Than Subsidies (via Clean Technica) The cornerstone appeal of carbon markets is their ability to cut emissions while creating clean energy investments – but it turns out they may be far more effective at the task than anyone could have ever imagined. Carbon markets reduce greenhouse…

Radio Waves Carry News of Climate Change

Their research shows that the strength of radio signals on the ground is a reliable indicator of temperature change above. Prof. Price and his team used simple radio antennae on the ground to measure radio waves broadcast by navigational transmitters around the globe, then compared information on the strength of these radio signals with data on temperature fluctuations in the upper atmosphere.

Study: ‘Waste heat’ May Reduce Costs for CO2 Capture

Rice University team seeks to optimize CO2 removal from power plant emissions In some of the first results from a federally funded initiative to find new ways of capturing carbon dioxide (CO2) from coal-fired power plants, Rice University scientists have found that CO2 can be removed more economically using “waste” heat — low-grade steam that cannot be used to produce electricity. The find is significant because capturing CO2 with conventional technology is an energy-intensive process that can consume as much…

Changing Temperatures Beginning To Affect Fresh Water Ecosystems

Everybody loves to visit the lake in the summer. Boating, tubing and water skiing are staple warm weather activities for lake communities and vacationers. This past summer was one of the hottest on record, and many people saw their dreams of fun summers on the lake dashed as low water levels and blistering heat made the shore much less appealing. The truth is, climate change is a real phenomenon that will eventually affect the quality of human lives in very…
