Embodied Carbon: Three reasons we should care

...energy and carbon because once I have the new windows I won’t have to use so much energy to heat my house. If I invest in buying their windows I’ll be saving money and saving the planet in one go, win-win, right?Unfortunately though it isn’t quite that simple. There are several stages to consider, explained in this short animation. Transcript All of these processes...

How we can all tackle our digital carbon footprints

...energy consumption required for housing (eg, heating, electricity and cooling), along with cutting travel in diesel or petrol cars, and eating less meat-based foods, will have a big impact on our individual footprints. But where does the digital carbon footprint fit in with this? When it comes to our digital carbon footprints, they are a fraction of our total carbon...

Explainer: Einstein's Theory of General Relativity

...energy, thanks to E = mc²) follow these straight paths in curved space. The experimental proof of this occurred during a solar eclipse in 1919 where starlight was observed to be bent by the sun. The amount of bending was predicted by Einstein, and not by the standard “Newtonian” theory. So matter follows the curvature of space, but we know matter is the source of...

Climate change and the built environment

...energy efficiency of new buildings has improved, and emissions per square metre have been reduced. However, we replace our building stock in Europe very slowly, at less than 1% per year. This means over 80% of our existing building stock will still be standing in 2050. Regulation on the whole still ignores embodied carbon impacts (although this has recently been debated...
