What Is Net Zero? Net Zero vs Carbon Neutral, Explained

“Net zero” appears in government plans, company reports and energy bills, but it is often misunderstood. It does not mean zero emissions, and it does not mean buying offsets and carrying on as usual. Here is what net zero actually means, how it differs from carbon neutral, and what it looks like for countries, companies and homes.

What does net zero mean?

The IPCC defines net zero emissions as the point where human-caused greenhouse gas emissions are balanced by human-caused removals over a given period. In practice, that means cutting emissions from energy, transport, industry, buildings and farming as far as possible, then removing the hard-to-avoid remainder with forests, soils or technologies such as direct air capture with storage.

Why does it matter? Because warming only stops when CO₂ stops building up in the atmosphere. Reaching net zero CO₂ is the point at which global temperatures stop rising from CO₂.

Net zero vs carbon neutral

Carbon neutral claims based on offsets are now under legal pressure: since September 2026, EU consumer law bans product claims like “climate neutral” that rely on offsetting. Net zero, done properly, is the more demanding and more credible goal.

What is net zero for a company?

The Science Based Targets initiative’s Net-Zero Standard asks companies to set a near-term target (about 5–10 years) and a long-term target to cut emissions across Scopes 1, 2 and 3, usually by at least 90% by 2050. Carbon credits cannot count toward those targets; only once the long-term target is met can permanent removals neutralise the residual emissions. The first step is measuring them; see what is the GHG Protocol? and Scope 3 emissions explained.

What is a net zero energy building?

A net zero energy building produces as much renewable energy over a year as it uses, typically by combining very good insulation, efficient heating and cooling such as a heat pump, and rooftop solar. A net zero carbon building goes further, also counting the emissions from its materials and construction.

Net zero is not a licence to keep emitting. It is a plan to stop, with removals only for what truly cannot be cut.

Net zero targets by country

Most of the world’s economies now have a net zero or carbon neutrality target, although they differ in date, legal status and scope. The United Kingdom put a 2050 net zero target into law in 2019, and the European Union did the same through its European Climate Law. China has pledged carbon neutrality before 2060 and India net zero by 2070. Many smaller countries have earlier dates. What matters most is not the long-term date but the near-term path: whether emissions are actually falling this decade, which is what the new round of national climate plans (NDCs) is meant to show.

Common criticisms of net zero

Net zero has critics, and their concerns are useful for spotting weak targets. Distant dates can be used to delay action now. Some companies lean heavily on cheap offsets rather than cutting their own emissions. Removals are often assumed at a scale that does not yet exist, and nature-based removals such as forests can be reversed by fire or logging. Targets sometimes leave out Scope 3, where most of a company’s footprint lies. A credible net zero plan answers all of these: near-term targets, deep cuts, Scope 3 included, and only permanent removals for the small remainder.

Net zero at home

For households, the biggest steps are usually the same everywhere: insulate and switch heating to an efficient heat pump, use efficient lighting and appliances, move to an electric car or public transport when you can, and choose renewable electricity or rooftop solar. Small tools help too: an energy-monitoring smart plug shows where your electricity actually goes.
