PRODUCT CARBON FOOTPRINT: TRUST DESPITE COMPETITION
—— A product’s carbon footprint is becoming increasingly important for companies and the market. TÜV SÜD offers to verify this—and supports companies in gaining the trust of clients and consumers.
Back in 1833, the British economist William Forster Lloyd observed a behavior that continues to characterize many of the world’s problems to this day. Lloyd noticed that numerous pastures accessible to the general public, known as the commons, were in a pitiful state: the grass withering, the land covered with cow dung, the cattle emaciated. Lloyd found that the reason for this over-use was the individual desire for profit without regard for the long-term consequences, a situation that he termed the tragedy of the commons.
In 1968, the ecologist Garret Hardin revisited Lloyd’s idea and wrote an article entitled “The Tragedy of the Commons.” Hardin’s sobering conclusion: ultimately, free access to public goods leads inevitably to their ruin. Scientists have been using the concept since then to describe very different situations. For example, overfishing of the oceans, the clear-cutting of forests, the polluting of waterways, the poaching of wild animals — even climate change — can all be traced back to the same quandary: although people act rationally at an individual level, their behavior ultimately harms themselves. In the fishing industry, for example, the catch for all fisherpeople initially increases, but then decreases because the fish stocks can’t recover and regenerate fast enough.
1. The traditional approach is the allocation of property rights. A fence divides the pasture. Farmer McDough and Farmer Smith are individually responsible for their part of the pasture, which changes their thinking. Long-term security now outweighs short-term gains. Both only send twenty cows to their parts of the pasture. Yet property rights cannot always be allocated and enforced everywhere. What works for a pasture often fails when it comes to deforestation in the rain forest because of the sheer size of the forests.
2. For some goods and areas, international law doesn’t provide for ownership. The atmosphere, for example, or a large part of the oceans, known as the high seas, belong to no one and everyone simultaneously. In cases such as these, international agreements have been established that, for example, set fishing quotas for the oceans or limits on carbon dioxide emissions. The problem with this is that those who ignore the quotas needn’t fear any punishment, as most agreements are voluntary.
3. A third way out involves neither the state nor property rights. As the Nobel laureate Elinor Ostrom has shown, some communities manage to use public goods in a sustainable way. For this to succeed, certain conditions must be met, for instance mechanisms for sanctions, community decision-making or mutual control. Only when members of a community take responsibility for their common resources can the benefits be sustainable for everyone.
