You are likely to hear much of the term “net-zero emissions” in the coming weeks, when the leaders and CEOs are under pressure to discuss what action they will take to reduce the impact on climate change of their countries and business.
Amazon, for instance, has just announced that its Climate Obligation has been joined by more than 200 businesses, who have pledged to achieve net-zero emissions by 2040.
But what is net zero emissions really all about?
Zero emissions, regardless of the net restraint, means that no greenhouse gases are generated.
Several countries, including the USA, have committed to reach the objective of net zero emissions by 2050.
Some projects, like planting trees, can take years to pay for themselves in emissions cuts, while the firms that buy forest offsets continue to emit greenhouse gases.
Every move produces greenhouse gas emissions.
It may be too costly or not technologically possible, to replace its steam boiler with a non-carbon product.
