By all indications, the choices we are making about climate change and energy now have the effect of selling out the interests of future generations, in exchange for greater wealth during the next few years. This connects to the central conflict of interest created by climate change: the disjoint between the interests of those who burn fossil fuels and those who suffer from the pollution that behaviour creates. All indications from the political system suggest that people will continue to undermine the interests of their own children and grandchildren, where doing so is personally financially beneficial to them.
Earlier, I brought up a radical proposal to align the interests of the elite with those of future generations. Unfortunately, no such proposal has any chance of success, because elites are highly influential and members of future generations are nothing but powerless victims.
Perhaps one way reduce the strength of the intergenerational conflict of interest is to adjust the voting system so that those who will experience more of the consequences of climate change have more of an ability to vote. Specifically, votes could be weighted so that those of younger people count for a bit more while those of older people count for less.
Each person could start with one guaranteed vote. Younger people could then be credited with additional partial votes, to represent their greater personal interest in the choices being made today. If we assume that people in Canada live to be about 80, that means someone who is 50 today is likely to live until about 2042. Somebody who is 20 today, by contrast, is likely to live until 2072. The amount of climate change experienced by the 20-year-old is likely to be substantially greater. They will also live longer with the consequences of all the other related choices we made: from designing electricity and transport infrastructure to managing conflict internationally.
One way to implement this idea would be to give everyone 1 vote, plus an additional 1/100th of a vote for every year they are likely to live (based on the simplification that everyone will live to be about 80). Someone who is 20 would therefore get their 1 vote, plus 0.6 additional votes to represent how long they will be on the planet. Someone who is 70 would only get 1 vote plus 0.1 additional votes.
Usually, the older someone gets, the worse the alignment is between their interests and the interests of society as a whole. (This is obvious in areas like health care, where those who are dying have every interest in unlimited public funding being devoted to keeping them alive.) Actually, this is a more general problem. An employee who knows he will be quitting in two weeks has little or no interest in the long-term health of the company. A tourist who is leaving a country in a couple of days has little interest in its long term health. Those who have little time left on the planet have every personal reason to support the pillage of the natural world, if it means their remaining time will be more prosperous and comfortable.
The young, by contrast, will be forced to live with the choices we make, right or wrong. If we do too little about climate change, they will suffer from all of the effects of that choice. Similarly, if we actually end up doing too much about climate change – scrapping too much fossil fuel infrastructure and building too much renewable energy capacity – it is the young people of today who will live poorer lives because of it.
The idea of weighing votes by age, even if it is philosophically and ethically defensible, is probably politically impossible. Older people are richer and more involved in the political process. They seriously outgun young people who are struggling to develop personal financial security and who are largely uninterested in voting. It may also be faulty to assume that young people will vote with their own long-term interests in mind. They may prove just as narrowly self-interested as older people have been. Instead of seeing policies developed that will encourage the emergence of a decent world for everyone in 2050 or 2100, they may just support policies that make the world of 2012 a little bit better for them personally.
