Every winter, air pollution becomes the central theme of a heated debate. The high levels of fine particles in the air, increased by the high pressure and the absence of wind typical of the Po Valley, triggers traffic limitation measures. This year the circulation of vehicles up to EURO 6 diesel was prohibited in Rome.
\nWood biomass, wood and pellet heating is also indicated as the main responsible for the smog emergency. It is necessary to avoid the spreading of partial information that does not promote concrete solutions. Opinion leaders and researchers expressed themselves categorically, citing data and expressing incomplete and sometimes misleading opinions.<\/p>\n
False. According to the latest GSE Statistical Report1 , the consumption of wood and pellets in the residential sector has remained stable over the past 6 years. At a regional level, the 2013 Arpa Veneto2 survey recorded a drop in wood consumption of 260,000 tons compared to the 2006\u2019s consumption.<\/p>\n

This is inaccurate. According to data from the AIEL Observatory, the number of generators is slightly decreasing, from 9.4 million generators in 2014 to 9.1 in 2018. At regional level Arpa Lombardia found that from 2008 to 2015 the generators remained 600,000 units. Arpa Veneto recorded a slight increase of 1% from 2006 to 2013 (672,000).<\/p>\n

No, quite the contrary. The European Environment Agency certifies that, in the past 30 years, there has been an improvement in air quality. In Milan in 2005 the days beyond the allowed limits were 152, in 2019 they were only 72. In the annual statistics the maximum peak in Milan was 309 micrograms \/ cubic meter in 2002, only 107 in 2019 (Arpa Lombardia data3 ). There have been critical periods this past winter, but measures in recent years have improved the quality of the air. In many regions, in particular in the Po Valley, permanent non-emergency measures have been adopted. From 2018 the law does not allow the use of generators up to 2 stars4 . From 1st January 2020 generators with at least 3 stars are mandatory: at least 1 million technologically obsolete and polluting generators have been turned off by law! This improves the quality of the air and the consumer can choose over 2,600 models of 4 and 5 star generators, classified as part of the AriaPulita\u00ae certification 5.<\/p>\n

AIEL has been demanding rigorous checks for years, so that the limits of use for old biomass appliances are respected. It is necessary to implement the regional registers of the heating systems, to guarantee the periodic maintenance of the appliances and ensure their optimal operating levels. In the daily use of the generator, the end user has a decisive role in keeping emission levels low: this is a way to empower the end consumer. In 2018 AIEL signed a Memorandum of Understanding with the Ministry of the Environment on these issues.<\/p>\n
This claim is incorrect. Arpa Lombardia surveys show that from 2010 to 2015 PM emissions from biomass combustion in the Lombardy Region have decreased by about 30%. The Arpa Veneto survey also confirmed a 20% reduction in PM produced from wood and pellets from 2006 to 2013. This happened thanks to the replacement of old biomass appliances with more efficient wood and pellet generators.<\/p>\n
No, much more needs to be done for sustainable mobility and domestic heating, to accelerate the transition from fossil fuels to all renewable sources. The biomass home heating sector is investing in research and technological innovation to make appliances more efficient and reduce their emissions.<\/p>\n
[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_column_text]<\/p>\n
To improve air quality, it is necessary to encourage the replacement of old wood and pellet systems with new energy efficient generators with low particles emissions. The first results of the Government Incentives in Italy are good. In 2017, 23.400 devices were replaced, with a reduction of 1.100 tons per year of particulate matter (PM) and about 80.000 tons of CO2 equivalent per year (Gse, 2018 6). In 2018, with 46.000 appliances replaced, we expect to double the environmental benefits, i.e. 2.200 tonnes less particulate matter (PM) per year, corresponding to 160.000 tonnes of CO2 per year. AIEL, the Italian Agroforestry Energy Association, believes it is essential that incentives for wood biomass are allocated to quality generators, with high yields and low emissions, as required by the Agreement between the Italian Ministries signed in June 2019 during the Clean Air Dialogue.<\/p>\n
The oil lobbies offer LPG, Liquefied Petroleum Gas, as an alternative to wood biomass. They consider it a clean and zero particles product. They forget that fossil fuels are primarily responsible for climate change because they emit CO2. For each megawatt hour of primary energy produced, diesel emits 326 kg of CO2 equivalent into the atmosphere, LPG 270 kg of CO2 equivalent, methane 250 kg of CO2 equivalent, pellets only 29 kg of CO2 equivalent, firewood 25 kg. of CO2 equivalent 7. Many other EU countries are also going in the opposite direction of fossil fuels. The Austrian government has decided to ban the installation of diesel boilers in new buildings. Norway has banned the use of diesel and kerosene for heating buildings (source: Bioenergy Europe).<\/p>\n
