• Air quality has improved enormously thanks to home heating switching to natural gas in 40 years since 1970

• It will continue to improve in next 40 years thanks to higher energy efficiency from better heating appliances—driven by climate agenda more than local air quality issues

• Today we can make a realistic assessment of the potential, based on known technologies

Air quality in Europe: The past and future role of natural gas

Home heating efficiency will improve: from existing technology as well as innovation

8

• 90 percent of Dutch gas-heated homes have condensing boilers … although take- up was slow in 1980s

• Average household consumption has halved from 3,145 m3 per year in 1981 to 1,620 m3 per year in 2010 in the Netherlands

• Only 25 percent of German gas-heated homes have these boilers; only 35 percent in the UK … there is lots of potential

• Next it will be gas heat pumps … micro CHP … and fuel cells

The penetration rate of improving technologies is key to achieving efficiency

• Incentives to replace existing equipment by promoting

more efficient equipment, such as gas heat pumps, condensing boilers and hybrid solutions;

• Incentives to use less polluting fuels, such as gas, biogas and biomass;

• Investment in rollout of hybrid technologies (gas and renewables);

• More rational use of existing equipment in dwellings; • Stricter energy efficiency standards for electric

appliances; • Active awareness campaigns to influence people’s

behaviour • Research and development in new efficient technologies.

What needs to be done for this to happen?
