When it comes to emissions, the 'too small to matter' argument is absurd, reckless and morally bankrupt
Simon Holmes à Court
Shortsighted, illogical and dishonest arguments are holding Australia back – and condemning us to more brutal summers

Australia is the 14th largest emitter out of 208 countries. If all countries with emissions under a “measly” 2% were lumped together we’d together be responsible for almost as much annual emissions as China and India put together.

The physics of the climate system doesn’t care about political boundaries. Does Germany not matter because it’s responsible for (slightly) less than 2%, or does it matter because it’s part of the EU, responsible for 9.4% of emissions? How about if we divide China into 56 countries of 25 million people, each with emissions half of Australia’s – would that let them off the hook?
Australia has the highest emissions per capita of all major nations. The average Australian has four times the carbon footprint of the average global citizen, significantly due to our unusually high reliance on coal for electricity, the poor energy efficiency of our vehicles and buildings and the high domestic emissions from coal and gas extraction and processing.

The “too small to matter” argument is logically absurd, but it is also morally bankrupt and economically reckless.

We all know that throwing one piece of litter out the window wouldn’t ruin the environment, but if all did we’d soon be surrounded by rubbish.

How about voting? It is a foundation of our democracy that nobody’s voice is so small as to be meaningless.

Likewise, if any one taxpayer stopped paying tax we all know it wouldn’t make a measurable difference to the government’s bottom line, but if everyone stopped paying tax it would smash consolidated revenue.
