I spent an interesting afternoon thinking of and discussing global warming in Heureka, the Finnish Science Centre, where the WWF Finland had invited its supporters for a seminar on the issue. A great deal of information and inspiring action - not only talk. After the seminar, I visited the centre's exhibition Klima-X on global warming: the floor had been filled with 40 000 litres of water, an ice cube was melting in the middle and visitors wore yellow boots (see below). In the evening, it was time to switch off the lights for an hour to spread the message of climate change in the biggest voluntary environmental event in the world, the Earth Hour.
Let's start with the embarrassing facts. A Finn has a carbon footprint of around 10 tons, this is twice as much as for a Swedish person and 10 times as much as for an Indian (however, the Americans can make even us look ecological, they have a carbon footprint again twice as big as we do!). In order to reach a sustainable level of emissions, we should cut it at least by a half - to start with. In order to do so, we have to focus on three main issues:
1) Housing (the biggest source of CO2 emissions in Finland, around 30% of our footprint),
2) Transports (20%) and
3) Food (18%).
The WWF has analysed which actions would have the greatest impact on our emissions, here's the list and some thoughts about it:
1) Favour real local food. This means growing and gathering some of your food yourself. Replacing a fourth of your food consumption by real local food would decrease your carbon footprint by 150 kg/year. Having a vegetable garden would of course be fantastic, but I think, for pragmatism's sake, I'll content myself with eating local food that I can buy from the market or grocery stores. I don't know how much picking mushrooms on my own actually differs from buying local mushrooms picked by someone else (wondering around in a forest is of course great fun). My own idea is that eating local food is not only ecological but also contributes to the livelihood of the countryside communities and small family farms.
However (!), as we heard in the seminar, the transportation of food represents only a small share of the CO2 emissions in the food production chain. Actually, one of the speakers, Tuuli Kaskinen, said that it's better to eat even tropical fruits if they just are seasonal instead of demanding local arctic strawberries in the winter time. In short, the key is to buy seasonal products no matter where they are produced. Obviously still, a beetroot or potato is more ecological than an avocado.
2) Reduce the amount of wasted food. An average Finn throws away 60 kg of food every year. By reducing this amount, you can save 190 kg emissions in a year. In a very illuminating documentary film, it was revealed that almost half of the food produced in the world doesn't end up feeding us. This phenomenon also increases the food prices hurting the poorest people in the world the most. Living alone, it is easy to monitor my own food consumption and I hardly ever throw anything away, if I do, it is with awful shame and regret. I wish other people would have this same green consciousness when they do their daily groceries. I guess one of the underlying problems is (for this and other climate change issues as well) the long distance to super markets: as people try to manage with only one weekly trip to the super market they end up buying much more than they actually need. In contrast, I go to the local small grocery store every second day to get my single-persons's portion of fresh veggies and bread.
3) Reduce by half your meat consumption. This reduces your carbon foot print by 200 kg/year. I completely agree with the author Risto Isomäki who at the end of the seminar said that halving is an absolute minimum as he believes that the gas emissions of meat production are most probably even bigger than we think not to mention the huge consumption of water connected to it, the pollution of the seas due to factory farming and the farms being a potential birth place of many disastrous diseases as seen with the swine flu. Tuuli Kaskinen gave some information on the emissions of different products:
Tofu or soya 2,0 kg CO2 emissions / kg
Poultry 3,6 kg
Pork 5,6 kg
Cheese 13 kg
Beef 19 kg (also the biggest consumer of water and if the beef comes from Brazil, the CO2 rises to 41 kg per one kilo of beef)
4. Map the energy consumption in your house. This can save up to 1640 kg/year. This way you can easily improve the energy efficiency in your house. Recommended especially for those lovely old villas with leaking attics and catastrophic insulation. Economic incentives are of course pretty inviting.
5. Change to green energy. An impact of 1100 kg/year in your carbon footprint. I have luckily been using ecological sources of energy in my flat ever since I was able to choose the firm myself, it's actually not even more expensive really. The more there are people using wind power or switching to solar panels, the cheaper these alternative sources of energy will be. Risto Isomäki told how solar panels cost half of what they used to after the decision of Spain and Germany to purchase them in large quantities. This means that the decision of one person can impact on some others and eventually make an exclusive form of energy available to large masses.
6. Heating your house with geothermal heat. An important impact of 1360 kg/year. Sweden is already subsidizing the building of geothermal heat pumps, and we should definitely follow them. No wonder, our dear neighbour is so much ahead of us in terms of carbon footprint. In the seminar film director John Webster answered a question on how much we should reduce our carbon footprint: "Just anything lower than in Sweden would be good." I wish the Finns would take the carbon footprint battle against the Swedes as seriously as our ice hockey matches.
7. Reduce your commuting emission. One day of teleworking a week would reduce carbon footprint by 146 kg/year, while changing to public transports is of course a must. I'm in a good position of being able to walk to work. But I know many who wouldn't take the 30 minutes walk every morning. This issue shows again how our whole urban planning should be thought over from an ecological point of view. Remote suburbs cannot be sustainable unless you accompany them with a metro line.
8. Replace car with a bike. It's the season! Biking 100 km a week during the green season reduces CO2 emission by 470 kg/year. We need better biking lanes as well as more tolls and less parking slots for cars in the centre. Equals better health for you and the planet.
9. More travelling by train instead of air plane. Try to replace one trip to the Southern Europe by plane and visit e.g. St. Petersburg by train instead, you'll reduce your CO2 emissions by 1140 kg / year. I've already planned a trip to Russia this spring by train. And obviously elsewhere in Europe, it's only easier.
The problem of climate change is unavoidable but we can impact on the extent of the problem with our own action. One way to demonstrate our interest, worry and willingness to act is the annual Earth Hour, organised today, the 31st March, for the sixth time. Last year it gathered 1.8 billion people to switch off the lights for one hour and this year the expected number of participants is 2 billion. The lights on Eiffel tower, Olympic Stadium in Helsinki, Sydney Opera Hall etc. are switched off from 20h30 to 21h30 local time. I had candlelit tea and crêpes. Symbolic things like this give hope, I even got a bit emotional watching this video.
