Large industrial plants are required to have and maintain an efficient process of Continuous Emissions Monitoring. In order to indicate that their processes are effective, and their emission monitoring systems meet the required criteria, there are carefully drafted EN Standards for assuring the high quality of permanently installed automated monitoring systems (AMS). In this article we will discuss the four stages of BS EN 14181 (2014): QAL1, QAL2, QAL3 and AST (Annual Surveillance Test). 

Emission monitoring refers to the on-going processes of collecting the data on the gases and components released in the air by industrial plants. In this article we will discuss the ABC of emission monitoring at a general level: What is emission monitoring? What needs to be taken into consideration when planning a well-oiled measuring process?

There is a vast body of literature on trees’ role in tackling the greenhouse effect, especially by reducing CO2 emissions. As is known, during the Northern winter, as our green friends hibernate, the CO2 levels skyrocket globally. When summer finally arrives in the North, forests get back to work and absorb a huge cloud of CO2, bringing the levels down. Trees, in other words, have always been one of our main allies in battling the greenhouse effect.
