I quote from web magazine, of danish ecovillagge network, Løsnet (International Climate Edition n. 61-62, dec 2009):New Study shows that Danish ecovillages have CO2 emissions 60% below the national average.
SummaryMeasurements of CO2 emissions at three Danish ecovillages by environmental
consultants Pöyry A/S earlier this year document that the their average CO2 emissions are a full 60% below the national average. The study is consistent with foreign studies which have shown that the “ecological footprints” of three ecovillages in the USA, Great Britain and Hungary were less than half of their respective national averages. The Global Ecovillage Network (GEN), numbering thousands of ecovillages across the world, has long argued that lifestyle change is a key strategy in reducing pressure on the ecosystem without sacrificing quality of life. Now we have additional evidence.
BackgroundThe ecovillage movement started in Denmark in 1991 and is growing steadily.
Denmark has more ecovillages per capita than any other industrialized country, and was the first to form a national network in 1993. Ecovillages are small sustainable communities, both rural and urban, both North and South. Southern members of
GEN are mostly traditional villages, e.g. 15,000 in Sri Lanka. The Northern variety are mostly intentional communities built by ecovillage pioneers who, through personal commitment and with little encouragement from governments, are designing and building small sustainable communities and teaching about sustainable living in their regions. The three in this study include two of the oldest, Svanholm and Hjortshøj, and one of the newer, more “mainstream” ecovillages, Munksøgaard near Roskilde, which is currently the largest in Denmark with about 250 residents.
MethodsPöyry AS was consultant to the Danish Climate Ministry “1 ton less” campaign,
and has used the same calculation model in this study. The report calculates only CO2 emissions. It does not consider other greenhouse gases. In addition, Pöyry looked at the effect of some special ecovillage CO2 emissions from:
1. Domestic production of organic vegetables, etc. on there own territories;
2. Organic products in general;
3. Water consumption and wastewater treatment;
4. The composting of organic waste from households;
The full report is posted on the website of the Association of Danish Ecovillages
(
LØS). "CO2 Emissions in Eco-villages”, Pöyry, July 2009".
Results:Average EmissionsA Dane emits on average 10 tones of CO2 per year, of which 3.8 tons are due to state and municipal works and the export of various goods. This means that every Dane is directly responsible for the remaining 6.2 tons. Emissions come from heating of homes, transportation, electricity consumption, water consumption and emissions associated with food and other consumables.
Ecovillage Data The average resident of the three Danish ecovillages emits just 2.5 tons of CO2 per year -60% less than the average Dane.
The difference lies primarily in that ecovillages:
•typically use CO2-neutral heating
(e.g. wood chips)
•have reduced transportation
•use primarily organic products
70% Less for Heating The Danish ecovillages’ home heating has no effect on CO2 accounts, since they all use CO2-neutral heating. It should be noted that the average ecovillage resident uses only 1825 kWh per year for heating –70% lower than the average Danish consumption of 5967 kWh per year.
37% Less CO2 from ElectricityA Dane emits on average 0.95 tons CO2/year due to electricity consumption. The
Danish ecovillages in the study emitted just 0.60 ton CO2/year –37% less. Svanholm’s CO2 emissions are zero because Svanholm produces all its electricity needs from its CO2-neutral wind turbine.
35% less CO2 from transportationThe Danish ecovillages emitted only 35% of the Danish average CO2 due to transportation. The lower CO2 emissions in the ecovillages are due to less driving in private cars, greater use of public transportation and less air travel than the average Dane.
29% less CO2 from general consumption. On average, the ecovillages emitted 29% less CO2 from goods consumption, due
to own food production, higher consumption of organic and eco-labeled products and more recycling than the average Dane.
12% less CO2 from water consumptionOn average, the ecovillages emitted 12% less CO2 due to water use. This in spite
of the fact that Svanholm – the largest organic farm in Denmark with over 400
hectares – uses substantial water for its large scale agriculture. The other two ecovillages emitted 56% less CO2 than the Danish average.
CO2 Emissions from Ecovillages are probably even lower.
Additional factors, which were not included in this study, would probably increase the ecovillage deviation from the average Danish household even more, for example, the importance of organic food production and local production in general, which saves packaging and transportation. Nor did the study look at the importance of the materials life cycle.
This means that some of the activities in the ecovillages are not yet sufficiently clarified, so here are obvious opportunities for further refinements.
Another topic that has not been studied in this context, and which the ecovillages would like to have studied, is the difference between conventional and organic/biodynamic agriculture in Denmark. There are foreign studies on this issue showing that organic/biodynamic agriculture is more resistant to climate changes than conventional farming. Moreover, the reports indicate that there is more stored CO2 in the soil in organic/biodynamic agriculture than in conventional. There is a great need for incorporating such factors into the discussions of climate strategies.
The Ecological Footprint The international focus right now is on green house gasses and the problem of
climate change. But the environmental problem is broader and includes a general overloading of the ecosystem and irresponsible use of non-renewable resources. These other aspects must not be forgotten. There are a number of
resource-saving measures in ecovillages, which have no effect on CO2 emissions.
