Step 1: Understand the term "net-zero emissions".
Net-zero means not adding new emissions to the atmosphere. This is achieved by reducing greenhouse gas emissions as much as possible and balancing out any remaining emissions by removing an equivalent amount from the atmosphere (e.g., through planting forests or using carbon capture technology).
Step 2: Identify countries with ambitious climate targets.
Many countries have set net-zero targets. The key is to know the specific target year for each.
Step 3: Pinpoint the country with the 2045 target.Sweden has one of the world's most ambitious climate laws, legally binding the country to achieve net-zero greenhouse gas emissions by the year 2045. Germany also has a 2045 target, but Sweden was one of the very first major economies to legislate this ambitious date.
