Time to imagine a new global economy – world socialism

Few folk deny climate change any longer. The scientific consensus is that fossil fuels are killing us. We need to switch to clean energy and do so with an urgency. But as important as clean energy might be, we still won’t avoid climate change. If we did achieve getting off fossil fuels and switch to 100% clean energy, a vital step in the right direction, the best-case scenario is that it wouldn’t be enough to avert climate catastrophe. The burning of fossil fuels only accounts for about 70% of all anthropogenic greenhouse gas emissions. The other 30% comes from a number of causes, including deforestation, and industrial livestock farming, which produces 90 million tonnes of methane per year and most of the world’s anthropogenic nitrous oxide. Both of these gases are vastly more potent than CO2 when it comes to global warming. Livestock farming alone contributes more to global warming than all the cars, trains, planes and ships in the world. There are also a number of industrial processes that contribute significantly, and then there are our landfills, which pump out huge amounts of methane – 16% of the world’s total.

That 30% chunk of greenhouse gases that comes from non-fossil fuel sources isn’t static. It is adding more to the atmosphere each year. Scientists project that our tropical forests will be completely destroyed by 2050, releasing a 200bn tonne carbon bomb into the air. The world’s topsoils could be depleted within just 60 years, releasing more still. Emissions from the cement industry are growing at more than 9% per year. And our landfills are multiplying at an eye-watering pace: the by 2100 we will be producing 11m tonnes of solid waste per day, three times more than we do now. Switching to clean energy will do nothing to slow this down.

When it comes to climate change, the problem is not just the type of energy we are using, it’s what we’re doing with it. What would we do with 100% clean energy? Exactly what we are doing with fossil fuels: raze more forests, build more meat farms, expand industrial agriculture, produce more cement, and fill more landfill sites, all of which will pump deadly amounts of greenhouse gas into the air. We will do these things because our economic system demands endless compound growth, and capitalism does not question this. Our focus on fossil fuels has lulled us into thinking we can continue with the status quo so long as we switch to clean energy, but this is a dangerously simplistic assumption. If we want to stave off disaster, we need to confront its underlying cause.

The environmentalist movement has made an enormous mistake. They focused all our attention on fossil fuels when we should have been pointing to something much deeper: the basic logic of our economic operating system. After all, we’re only using fossil fuels in the first place to fuel the broader imperative of GDP growth. The root problem is the fact that our economic system demands ever-increasing levels of extraction, production and consumption. Our politicians tell us that we need to keep the global economy growing at more than 3% each year – the minimum necessary for large firms to make aggregate profits. That means every 20 years we need to double the size of the global economy – double the cars, double the fishing, double the mining, double the McFlurries and double the iPads. And then double them again over the next 20 years from their already doubled state.

GDP growth has been sold to us as the only way to create a better world. But we now have robust evidence that it doesn’t make us any happier, it doesn’t reduce poverty, and its “externalities” produce all sorts of social ills: debt, overwork, inequality, and climate change.

Optimists claim that technological innovations will help us to decouple economic growth from material throughput. But sadly there is no evidence that this is happening. Global material extraction and consumption has grown by 94% since 1980, and is still going up. Current projections show that by 2040 we will more than double the world’s shipping miles, air miles, and trucking miles – along with all the material stuff that those vehicles transport – almost exactly in keeping with the rate of GDP growth. Clean energy, important as it is, won’t save us from this ecological nightmare. But rethinking our economic system might.
