#NetZero refers to achieving balance between greenhouse gas emissions produced and removed from atmosphere, becoming dominant framework for climate policy commitments (typically targeting 2050).
IPCC Framework
October 2018 IPCC Special Report on 1.5°C stated global emissions must reach net zero by 2050 to limit warming to 1.5°C. The concept allowed continued emissions if offset by carbon removal (forests, direct air capture, ocean fertilization). Net zero commitments proliferated: UK legislated 2050 target (2019), EU announced European Green Deal (2019), and by 2021, 130+ countries had net zero pledges.
Corporate Net Zero
Companies announced net zero commitments: Microsoft (2030, retroactive to 1975), Amazon (2040), Apple (2030). Skeptics questioned: vague timelines, reliance on unproven carbon removal technology, lack of interim targets, and continuation of business-as-usual with future technology bets. Critics coined “net zero greenwashing” for pledges without credible plans.
Carbon Offsetting Controversy
Net zero permitted polluters to continue emissions while buying offsets—often tree planting or forest preservation. Investigations exposed offset fraud: forests that would have existed anyway, double-counted credits, impermanent storage (fires destroying offset forests), and land grabs displacing Indigenous communities. Activists demanded actual emissions cuts, not accounting tricks.
Justice Concerns
Climate justice advocates argued net zero allowed wealthy nations and corporations to delay reductions while global south bore climate impacts. “Net zero” rhetoric obscured equity questions: historical responsibility, per-capita emissions, and right to development. Calls emerged for “real zero”—absolute emissions reduction without offsets.
Policy Dominance
Despite controversies, net zero became universal climate policy language. Paris Agreement tracking shifted to net zero pledges. The framing’s flexibility enabled broad adoption but risked ambition dilution through loopholes, distant deadlines, and offset reliance rather than rapid fossil fuel phase-out.
