• 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

Natural gas benefits Europe both north and south
Britain before natural gas
Greece before natural gas

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

• 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?
