Besides CO2, there are five other important types of greenhouse gases: methane (CH4), nitrous oxide (N2O), and three groups of fluorinated substances: HFCs, PFCs and SF6. These gases have a greater potential to contribute to global warming (per kg of emissions) than CO2 – 21 times in the case of CH4 and 23,900 times in the case of SF6.
CH4 and N2O occur naturally in the atmosphere but are also emitted as a result of agricultural and industrial activities. HFCs, PFCs and SF6 are mainly man-made gases. Due to their higher Global Warming Potential (GWP), relatively small emissions of non-CO2 greenhouse gases (GHGs) can make a large contribution to climate change. While energy efficiency and the use of renewable energy are effective strategies for reducing CO2 emissions, very specific knowledge about emissions sources and reduction technologies is needed in the case of non-CO2 GHGs. Equally important is designing and implementing stringent, effective policies to encourage measures for reducing the emissions.

We have extensive expertise in applications, markets and technologies related to non-CO2 GHGs. Our knowledge of emission profiles in a number of countries and regions is based on extensive experience of monitoring methodologies and emission inventories. In addition, our expertise in discerning market trends and identifying emission reduction options, combined with our experience in evaluating policies, provides an excellent basis for developing and implementing non-CO2 abatement strategies. |
Our services
