The ubiquitous climate pledge that nearly every country and corporation adopted, promising carbon neutrality by mid-century despite vague plans.
UK Leadership
The UK passed net-zero by 2050 law in June 2019, becoming the first major economy with legally binding target. Other nations followed: France, Denmark, New Zealand, Japan, South Korea, and eventually China (2060) and U.S. (2050). By COP26 (2021), countries representing 90% of global GDP had net-zero pledges.
Corporate Bandwagon
Corporations rushed to announce net-zero pledges: Microsoft, Apple, Amazon, BP, Shell, Delta Airlines. By 2021, over 3,000 companies had net-zero commitments. Environmental groups welcomed momentum but noted most plans relied on future carbon capture technology and offsets rather than immediate emissions cuts.
Greenwashing Concerns
Analysis revealed many net-zero pledges were greenwashing: vague timelines, questionable offsets, loopholes excluding supply chains, and assumptions about unproven technology. The New Climate Institute found 24 major companies’ net-zero claims had “very low” integrity. Still, the concept shifted business expectations—climate action became expected, not optional, even if follow-through lagged rhetoric.
