How do we live sustainably? The holistic nature of the problem makes definition difficult, but that doesn’t prevent us from having a go at it. We must try and define the problem, as this is usually the first step towards finding a solution.
Problem: We are not living within our environmental means, we are exceeding our emissions budget. To put it another way, we are in environmental debt. To continue to get into environmental debt just leaves another problem for our descendants to solve. If that weren’t bad enough, this environmental debt is already causing the climate to change in unpredictable ways, affecting our oceans and the biosphere dramatically. So not only will we leave a mess behind, but it will be a dangerous and unpredictable mess!
Solution: To stop eating into our environmental capital, our rainforests, oceans, atmosphere and biosphere.
That sounds simple enough, doesn’t it. But of course it isn’t that simple, mainly because we are either unaware of the cause of environmental debts or because our supposed happiness is predicated on a way of life that is inherently damaging, and we are unwilling to give up this way of life. Old habits die hard.
The change of habits and the introduction of cleaner systems does come at a price, change costs something, whether in time, materials or opportunity costs. But the cost of innovation is usually short-lived and then pricing tends to return to a level below where we started from. This is what pays for innovation and it doesn’t happen unless that promise of low costs is there.
Clean Energy: We need to replace our dirty grid with clean energy, which will take more than a generation as the lifespan of these systems is very long. But this has already started and there is widespread recognition that this needs to happen, so that battle is largely won. Sadly we have a government that doesn’t quite see this, but fortunately governments are temporary. Support a clean energy project near you today!
Get rid of the gas-guzzler: We need to stop using combustion for heating and transport. The Internal Combustion Engine has had its day, lets bury it with full honours and move on! Fortunately cars and domestic boilers have a relatively short lifespan and give us regular opportunities to change our habits. We will need to make a decision to take a risk by changing to a hybrid or fully electric vehicle when the opportunity offers, or to install a heat pump. We can’t rely on a push from government.
Buy Wisely: We need to stop importing goods from economies that aren’t moving in the direction of emission reductions, both to guarantee local jobs and to reduce the emissions of transporting goods half-way around the planet when we could easily make them on our doorstep. It would be nice if a carbon tax was added to imports that highlighted their environmental costs, but we can add that cost in our mind when we think about pressing that button online.
Waste: We need to reduce waste to a minimum, wasted materials, wasted energy, wasted heat. This is the most difficult one, as it is so closely related to behaviour. Persuading people that a walk to the shop is better for them and for the planet doesn’t sound difficult, but some people love their cars. There is an interesting shift in the use of health gadgetry to inform people about their health related behaviour that will help to achieve this. Insulating our homes will be a once in many generations cost. Consider whether you want your children to inherit an expensive home to inhabit, or a low energy home. If you only consider your own costs you won’t be motivated enough to spend the money.
Move into Town: We need to stop seeing a bucolic life in the country as the barometer of success. The country has nice views and fresh air, but it also has long travel distances to the doctors, the shops, the post office, the theatre and for every trip you have to make, the delivery van has to make one too. Move into town! Open a tea shop!
