Environment

Climate change today is considered one of the biggest political, economic and technological challenges world wide. Climate researchers believe that the only way to limit the rise in global temperatures by a tolerable 2 °C is to halve global emissions of greenhouse gas in the long-term.

The European Union committed itself to reducing overall greenhouse gas emissions by at least 20% by 2020 compared with 1990 levels.

Gas can play an important role in helping Europe meet this ambitious goal and mitigating climate change.

Gas is one of the cleanest traditional sources of energy emitting up to 50% less carbon dioxide (CO2) when burnt than other fossil fuels and has lower emissions of nitrogen oxide (NOx), sulphur oxide (SOx) and particles.

Because of its higher hydrogen to carbon ratio, the combustion of natural gas results in 25% - 30% less CO2 than for oil and 40 - 50% less than for coal per unit of energy produced depending on the process and fuel quality.

Gas is the fuel of choice for high efficiency cogeneration, providing significant energy efficiency and energy saving opportunities. Using gas can also improve air quality, including through use as a fuel for vehicles or heating, and reduce acid deposits.

Gas can also be used in energy schemes in combination with renewable energy sources.

Gas unites climate and environmental protection with efficiency, convenience and economic viability.
