The CO2 Economy – The Transformation of Carbon Dioxide from a Liability to an Asset

Carbon Capture and Utilisation or Recycling (CCU or CCR) and related technologies could play an important role in a future sustainable and diversified energy supply with lower greenhouse gas (GHG) emissions. CCU entails capturing CO2 from large emitters like coal-fired power plants and re-utilising it to manufacture useful products; as such, CCU represents an alternative...

A Science Perspective on the Volkswagen Emissions Scandal

When I initially heard about the VW scandal, it was secondhand and I hadn’t read any of the news yet, I didn’t have any of the facts. But I remember thinking (and saying), I don’t know what the big deal is about, everyone knows those chassis dynamometer tests they use for estimating emissions don’t get...

A Black Future for Coal

King Coal – as the most widespread and cheapest fossil energy source is often called – is entering a crucial, maybe definitive, phase. Indeed, worldwide coal consumption has decreased significantly in recent years due to a growing hostility to the generation of electricity using unsustainable coal. This global opposition comes from several different sources: political,...

The UN Climate Change Conference in Paris: Q&A with Rómulo Acurio Traverso

Rómulo Fernando Acurio Traverso is the Deputy Representative of Peru for Climate Change. In this function, he played a central role in the previous United Nations Framework Convention on Climate Change (UNFCCC) conferences and is currently preparing the 21st Conference of the Parties (COP21) in Paris this year, where 96 countries will come together to...

Choosing the Right Trees for Urban Greening

Many cities are currently creating more green spaces and planting trees. The growing momentum to increase the amount of green space in urban areas, seen, for example, in various ‘Million Tree’ campaigns, brings many benefits to urbanites. A reduction in summer temperatures, additional recreational opportunities, and storm-water control are among the motivations behind such programmes....

Fugitive Emissions in Shale Gas Production Negate Climate Benefits

It is often claimed that a higher ratio of natural gas to coal in our energy mix can mitigate current carbon dioxide emissions and serve as a ‘bridge’ to future renewable-based scenarios. This is because the carbon footprint of energy produced through the combustion of methane is about half that of energy produced from coal....
