Flare Gas

According to the latest estimates, about 150 billion cubic meters (or 5.3 trillion cubic feet) of natural gas is flared or vented every year - the equivalent of about 30 per cent of the European Union’s annual gas consumption.

NEL - Gas Flaring and Venting

Apart from being a major waste of a valuable energy resource, gas flaring and venting also emits greenhouse gases and other harmful pollutants and particulates into the atmosphere.  In response to this, governments around the world are taking action to reduce levels of flare gas and vent gas, with the most prominent legislation existing within the EU, Norway, Canada and the US.

Read about NEL's work with Mexico’s hydrocarbon regulatory body to help develop an oversight process to monitor adherence to regulations.

The integrity of flare gas and vent gas data is crucial if reductions are to be genuine and transparent. This is reflected in the measurement and reporting guidelines introduced in support of legislation and burgeoning emissions reduction schemes being introduced worldwide.
