A little more than a century ago Fritz Haber invented a way to make synthetic ammonia out of pure air. The process was soon scaled up for industrial use by Carl Bosch. The method known as the Haber-Bosch process revolutionised agriculture.
Two new scientific studies say that the effectiveness of cutting a range of non-CO2 gases such as methane and black carbon to limit global warming to 2°C has been strongly and consistently overestimated.
Making biogas from manure results in reduced greenhouse gas emissions and the production of a renewable fuel. The technology is far from its full potential in Europe, but also has some serious limitations.
The EU’s new climate and energy policy for 2030 opens the way for more ambitious clean air targets. The air pollution limits for 2030 proposed by the Commission last December could be achieved at €5.5bn less cost per year when the climate and energy package for 2030 ..
Gas is better than coal, but not good enough. Much of it has to be left in the ground, so its use has to be cut fast. This is actually happening in Europe. Gas use fell by 13 per cent between 2010 and 2013.
Particle pollution is not a purely local problem. Transboundary pollution transport is a major contributor to urban PM2.5 levels, and reductions in both primary PM and secondary precursor emissions are needed to bring down PM2.5 to safe levels.
The European Commission issued a reasoned opinion in September 2014 due to a failure to comply with EU requirements on industrial emissions, stemming from the Directive 2001/80/EC on Large Combustion Plants (LCP).
