The Paris Agreement, ratified by 196 nations in 2015, requires countries to submit Nationally Determined Contributions every five years representing progressively ambitious emission reduction strategies targeting global temperature increases below 2°C. Current national pledges collectively place the world on track for 2.5°C warming by century's end, falling short of the agreement's 1.5°C aspiration. Greenhouse gas accounting categorizes emissions into three scopes: direct operational emissions, indirect purchased energy emissions, & value chain emissions that often represent 80-90% of organizational footprints. Climate terminology distinctions between net-zero, carbon neutral, & climate positive prove essential for assessing commitment credibility & preventing greenwashing.
