Lately there have been some interesting headlines. “Hybrids less sustainable than Hummers” was the general gist of a CNW report analyzing so-called ‘dust to dust’ emissions impacts from manufacture and use, a full life-cycle analysis (LCA) if you will. Are there some tenuous assumptions at the root of this? Probably. Is there any truth to it? Yes. This is a prime example of why life-cycle analysis is important- buying a car because it is more efficient to use ignores the environmental costs that the consumer doesn’t see- when there is no requirement for companies to build these costs into the products, there is no incentive to avoid them. In the end, auto makers care more about selling cars, while the market must demand efficiency. However, the use of LCA to justify the ‘green superiority’ of current technology over emerging technology is misleading. The truth is, nobody who buys a hummer or a hybrid is doing the environment a favour- both require enormous energy and raw materials to produce, and require fossil fuels to operate. However, whereas hybrids can reduce ongoing fuel use, especially as energy for production can increasingly be sourced from cleaner alternatives (such as renewables), conventional gas-guzzler technology marries consumers to a future of increased fossil fuel dependence. Hybrid technology is at the beginning of its cycle- meaning it is more costly to produce (financially and environmentally) at this point in time, but as adoption grows and efficiencies from scale can be acheived, these costs will be expected to decrease. Choosing a hybrid therefore means being part of the vanguard of market transformation, as opposed to being part of the resistance to it.
The same analysis applies to the debate on local vs. imported foods. Fuel use in transportation is not the only environmental impact of food production, and evaluating food with this metric alone ignores the fact that some places are simply better for growing more food at a lower cost (both financial and environmental). Agriculture and specialization are social advances that allowed us to produce more, using less energy than our hunter-gatherer ancestors. That being said, a lack of inclusion of environmental costs throughout food production and supply chains means that consumers are once again left without any clear indication of what is the more ’sustainable’ choice.
It turns out a big reason for CNW’s low scoring of hybrids in terms of environmental impact stems from the quantities of nickel used in their batteries. Much of this comes from our very own Sudbury, Ontario, and the operations there have not had a stellar record in terms of the environment (though they are improving). So how can Toyota minimize the impacts of the nickel that goes into their batteries? The choices, including buying nickel somewhere else, or switching technologies (future hybrids will almost certainly use lithium batteries, for capacity reasons) may not make economic sense- and we can’t expect companies to operate against prevailing economics. If Inco or Falconbridge on the other hand had to factor environmental costs into their prices, then there would be an economic incentive both for them, and their customers, to seek less polluting alternatives. Unfortunately, leveraging a local tax or fee against a commodity will necessarily harm export revenues- few governments would be willing to take this on as a policy project.
On the other side of the coin, would increasing the costs of such commodities mean that technologies such as hybrids wouldn’t get developed? Well, let’s not forget that steel, petroleum and other more conventional raw materials all have associated costs too- a comprehensive integration of environmental impacts into all raw materials would drive us to use less of everything- maybe we’d forget about the hybrids vs. hummers debate and be riding bicycles more.
LCA is important in evaluating the overall impacts of the products we buy and use, but asking consumers to make choices where the economic realities don’t reflect the environmental realities doesn’t make sense. It all comes down to creating economic instruments that reflect the existing externalities associated with industrial activity. While there is opportunity for voluntary action by companies, what consumers need are standards and assurances of transparency, without having to do all their homework themselves. We clearly need policies to put this in place- unfortunately this will probably degenerate into finger pointing over who bears the responsibility for what costs, and how much each industry and sector must pay.
Governments have to start thinking strategically- like some of the best-in-class companies who are taking the lead on environmental issues, and creating the infrastructure needed to transform themselves. Think of BP, DuPont or Shell as companies that have taken on the responsibility to transform themselves towards sustainability. This requires the destruction of traditional sources of value, but in the end will enable the creation of new ones which are better positioned for the future. In particular, Canada cannot let itself become complacent in an environment of rising commodity prices. The resource sector is booming, but we are already seeing a rapid erosion of domestic ownership in resource companies. While our natural endowment in resources is largely responsible for our strong economic position now, if we don’t invest in innovative sectors such as clean technology, we risk compromising future competitiveness.
