Although they contribute only 0.15% to the world's greenhouse gas emissions, the governments of New Zealand and Costa Rica have independently expressed their intents to become carbon neutral in the next decade, with Costa Rica aiming to achieve an ambitious target of becoming carbon neutral by 2021. In doing so, it would become the world's first carbon neutral country, with the expectation of influencing policy decisions in other major countries. The proposal hopes to ignite the interest of private companies to engage in practices that reduce their emissions, for example, using more fuel efficient routes in transportation, relying more on digital documents than printed ones, adopting LED lighting in offices and using more efficient air conditioning systems.
