World View of Global Warming

A carbon footprint is “the total set of greenhouse gases (GHG) emissions caused by an organization, event or product”. For simplicity of reporting, it is often expressed in terms of the amount of carbon dioxide, or its equivalent of other GHGs, emitted. The concept name of the carbon footprint originates from ecological footprint discussion. The carbon footprint is a subset of the ecological footprint and of the more comprehensive Life Cycle Assessment (LCA). An individual, nation, or organization’s carbon footprint can be measured by undertaking a GHG emissions assessment. Once the size of a carbon footprint is known, a strategy can be devised to reduce it, e.g. by technological developments, better process and product management, changed Green Public or Private Procurement (GPP), Carbon capture, consumption strategies, and others. The mitigation of carbon footprints through the development of alternative projects, such as solar or wind energy or reforestation, represents one way ...

Get on a plane, and carbon emissions aren't the only environmental problem to think about. Aviation fuel is the largest source of lead emissions, and Friends of the Earth is calling on the EPA to get it under control. The EPA identified at least 16 regions last month that do not meet clean air standards on airborne lead emissions, and just about every one of those regions contains an airport that allows leaded aviation fuel. Nearly 20,000 airports in the U.S. allow leaded fuel, which is said to contribute half of the nation's total lead air emissions. Marcie Keever, legal director of Friends of the Earth, which has been pushing the EPA to phase out lead from aviation since 2003, said : "The recent findings of clean air violations reinforce our concerns: Fifteen of the sixteen areas declared to have unsafe levels of lead in air are in counties that contain at least one airport where lead is emitted." ...Leaded aviation fuel is primarily used in piston en...

Image: GOOD Ever wonder how much electricity it takes to keep a single light bulb running for the year? The folks over at GOOD did, and they produced this great infographic to make the answer (alarmingly) clear. The short of it? It takes way more than you'd think. Here are a few of the more surprising revelations from the piece:

One of the most stark before-and-after shot you'll see this Earth Hour; Hong Kong's Victoria Harbour lit up like the proverbial Christmas tree, then extinguished at 8:30...        

I ndia observed the Earth Hour with 92 other countries between 8:30 pm and 9:30 pm on Saturday. As the clock struck 8:30 pm on Saturday, hundreds of Delhiites and people in other cities voluntarily switched off their lights for one hour to observe Earth Hour, a global climate awareness initiative.   The Earth Hour is a global initiative by World Wide Fund for Nature (WWF) that aims to send out the message on climate change and that policy makers should make it their foremost priority.
