Overview

Carbon neutrality (net zero) balances emissions with removals. The IPCC (2018) found that limiting warming to 1.5°C requires global net CO₂ emissions to reach zero around 2050. Under the Paris Agreement countries submit NDCs. Korea declared 2050 carbon neutrality in 2020; its Carbon Neutrality Act (in force March 2022) sets a 2030 floor of a 35% cut from 2018, and the national NDC is 40%. Tools include renewables, efficiency, natural sinks, CCUS and carbon pricing — internalising an externality. Relying only on offsets invites greenwashing criticism; see RE100.

Frequently asked questions

Net zero vs carbon neutral?
Often interchangeable; net zero may cover all greenhouse gases.
