What is net zero?
We’ve all heard the term net zero, but what exactly does it mean? Put simply, net zero refers to the balance between the amount of greenhouse gas produced and the amount removed from the atmosphere. We reach net zero when the amount we add is no more than the amount taken away. But how can we achieve this and why does it matter? From countries and companies to individuals, tackling climate change is at the top of the agenda; and one way we can help to do this is to reach net zero. Indeed, the UK was the world’s first major economy to set a legally binding target of being net zero by 2050.
What does it mean to be net zero
Net zero means achieving a balance between the greenhouse gases put into the atmosphere and those taken out. Think about it like a bath – turn on the taps and you add more water, pull out the plug and water flows out. The amount of water in the bath depends on both the input from the taps and the output via the plughole. To keep the amount of water in the bath at the same level, you need to make sure that the input and output are balanced. Reaching net zero applies the same principle, requiring us to balance the amount of greenhouse gases we emit with the amount we remove. When what we add is no more than what we take away, we reach net zero.
Why is net zero important?
Net zero is important as it’s the best way we can tackle climate change by reducing global warming. What we do in the next decade to limit emissions will be critical to the future, which is why every country, sector, industry and each one of us must work together to find ways to cut the carbon we produce.
What’s the difference between real zero and net zero?
Given the impact that carbon emissions have on our planet, you might wonder why we aren’t aiming for zero, or real zero, rather than net zero. Real zero would mean stopping all emissions, which isn’t realistically attainable across all sectors of our lives and industry. Even with best efforts to reduce them, there will still be some emissions.
Net zero looks at emissions overall, allowing for the removal of any unavoidable emissions, such as those from aviation or manufacturing. Removing greenhouse gases could be via nature, as trees take CO2 from the atmosphere, or through new technology or changing industrial processes.
