An accepted solution to the problem of limiting climate change is to reduce greenhouse gas emissions. This makes sense because the evidence that greenhouse gases are a key climate driver has strengthened and because emission reduction is both doable and desirable. Carbon neutral and carbon zero are policy and practical frameworks to achieve emission reductions that help motivate our actions.
Carbon zero is just that; no greenhouse gases are released as a result of human activities. The policy seeks zero carbon pollution. Obviously this is tricky to achieve because most of our economic activity requires machinery powered by fossil fuels or electricity generated by coal or gas.
Given that agriculture, land management, transport, electricity generation and manufacturing all release greenhouse gases, an economy with zero emissions is a huge challenge. It is only possible after a serious, technically difficult, and costly transition away from a fossil fuel dependent way of life.
But it does send an interesting message.
Aiming for zero emissions is a commitment to a fundamental shift in the way we do business. It forces a whole of system view on understanding the consequences of manufacturing, production and resource use, not just on emissions but also on other unwanted environmental and social impacts. It is also a big picture view that makes tremendous sense because, even if we put aside the pollution issue, fossil fuels will eventually become scarce. With scarcity will come expense.
Carbon neutral is a different approach. It allows greenhouse gas emissions so long as an equivalent amount can be offset by emission reduction, visit here avoided emissions and/or carbon sequestration somewhere else. You can emit so long as you buy from someone else emissions they have legitimately saved or avoided to balance out yours.
