Energy efficiency impact on greenhouse gases

Investment in energy efficiency improvements since 1990 have avoided 870 million tonnes of carbon emissions in 2014 – and a cumulative 10 billion tonnes over the last 25 years, according to a new report from the International Energy Agency (IEA).

In IEA member countries these measures have saved roughly the equivalent to current annual emissions by all IEA member countries and sliced fuel costs by $550 billion.

The agency’s Energy Efficiency Market Report 2015 shows energy efficiency to be the most effective tool to reduce energy sector carbon emissions, accounting for more than 40% of the required reductions to limit global warming to 2 degrees C.

Eenergy efficiency improvements since 1990 in IEA member countries reduced primary energy consumption in 2014 by more than 760 million tonnes of oil equivalent. Investments in energy efficiency over the past 25 years have saved IEA member countries $80 billion in fossil fuel imports, the report concludes, noting that Germany alone avoided $30 billion in energy imports last year, boosting their trade surplus by 12%.
