For every four people aged between 15 and 64 in Europe, North America, Australia, New Zealand and Japan, there is now one person over Kamrul HassanMurdoch University. To test our theory that older people help to reduce CO 2 emissions, my colleague Ruhul Salim and I used an analytical tool called the Environmental Kuznets Curve EKCnamed after the economist Simon Kuznetswhich describes an inverted U-shaped relationship between emissions and economic growth.

The wider context The findings of our research should be taken with care. Write an article and join a growing community of more than 77, academics and researchers from 2, institutions. The direct link stems from the consumption patterns of people aged over You might also like Gas trap.
I should point out here that while the EKC has been applied to a wide range of environmental pollutantsit was not specifically developed to analyse greenhouse emissions.

Expert Database Find experts with knowledge in: Effective age of retirement — www. Of the baby boomers born between andthe oldest are now well into their sixties, and in their lifetimes fertility rates have fallen while life expectancies have climbed.
Indirect effects Now to the indirect effect, which works through labour market dynamics. In the United States, where average food energy intake increased markedly between the early s and the late s for almost all age groups, those aged 60 and above were the only ones to buck the trend. A New Zealand survey showed that consumption drops significantly after retirement. We found karmul ways in which population ageing may reduce CO 2 emissions — one direct, the other indirect.
An ageing population is associated with lower workforce participation rates, causing a slowdown in economic growth, which in turn reduces emissions.

Should I kill spiders in my home? Although many of the conveniences that address age-related changes, such as automobiles, elevators and air-conditioning, are highly dependent on energy, the limited mobility of older people is likely to put downward pressure on CO 2 emissions caused by their energy use.

Meanwhile, the US Consumer Expenditure Survey shows that levels of fuel use by older households are substantially smaller than in younger households.
Do old people emit less carbon dioxide? The other issue to consider is whether the emissions cuts bqppy by ageing people in the developed world will be swamped by the expanding middle class and haassan fuel use of developing nations. First, we consider only CO 2 emissions, and not other pollutants such as sulphur dioxide.
Energy production worldwide has become even more reliant on coal.
We found that an ageing population has significant negative influence on CO 2 emissions. And this proportion is growing — by the end of the century, there will be two overs for every five people of working age.
Second, many OECD countries are adopting policies to motivate older people to work longer.
In many parts of the world, and particularly in developed countries, populations are getting older. The pattern is also reflected in diets.
World greenhouse emissions reached a new record in and will be even higher indriven largely by the continued use of fossil fuels such as coal. In many countries, the effective age of retirement the age that people actually stop working rather than the age at which they are officially supposed to retire has begun to increase after a sustained fall since This implies that an older person is likely to use less private transport, which in turn results in reduced emissions.
Put simply, older people eat less. Consumption patterns and the nature of needs during old age is such that the provision of basic needs like good health, healthy social relations, security — all of which are less energy-intensive — become more important than discretionary consumption.
Now to the indirect effect, which works through labour market dynamics. It is likely that emissions reductions in developed countries may not help the global climate effort if developing countries do not take appropriate and effective measures to reduce their own emissions. Joost J Bakker Hassxn. My recent research has found that, in rich countries at least, ageing populations might help to drive down greenhouse gas emissions. Hasssan people in many countries are less likely to bap;y a car.
Population ageing will put significant pressure on the fiscal policies of governments around the world. This is because economic growth initially increases pollution, but beyond a certain level of per capita income it reduces it. Healthcare and pension systems are expected to bear the brunt, while ageing populations will shrink the labour force, putting downward pressure on economic productivity.
