The document asserts that corporate net-zero targets are fundamentally dependent on the continued function of natural carbon sinks, which are currently declining. It argues that value-chain decarbonization alone is insufficient because significant nature-related emissions occur in informal sectors and many companies lack science-based targets. To address a projected $4.1 trillion finance gap for nature, the briefing proposes that if 1,700 of the world's highest emitters compensated for 10% of their annual emissions through nature-based solutions, they could mobilize 30 Gt of climate solutions by 2030, representing over 10% of the remaining 1.5°C carbon budget.

The We Mean Business Coalition presents a series of policy asks across key sectors—including energy, transport, industry, and the built environment—to align global economies with a 1.5°C trajectory. The document highlights existing corporate commitments, such as the 900+ companies aligning with 1.5°C targets, and calls for government action on carbon pricing, the elimination of fossil fuel subsidies, and the implementation of just transition plans. It emphasizes that a green recovery from COVID-19 can boost GDP and employment while addressing the climate and biodiversity crises.

The document outlines a comprehensive leadership framework for companies to address the climate crisis. It emphasizes setting science-based net-zero targets aligned with a 1.5°C pathway, integrating climate goals into core business strategies, advocating for bold public policy, and maintaining transparent disclosure of progress and governance.

The We Mean Business Coalition analyzed 30 early adopters of the EU's Corporate Sustainability Reporting Directive (CSRD) to showcase innovative solutions for challenging disclosure requirements. The report highlights diverse approaches to double materiality assessments, TCFD-aligned climate risk quantification, Scope 3 emissions 'hot-spotting', and supply chain due diligence. It emphasizes that while many early adopters are only partially aligned with the regulation, their methods for reporting on internal controls, whistleblower cases, and climate transition action plans serve as practical guides for companies facing mandatory reporting from 2024.

The document argues that current corporate GHG accounting often conflates physical inventories with market-based performance accounting, leading to opacity and lackluster climate finance. By analyzing the Paris Agreement's architecture—which strictly separates national physical inventories from market-based 'emissions balances'—the authors propose a more robust corporate framework. Key recommendations include adopting dual-ledger reporting, establishing governance bodies for accreditation of market instruments, and implementing standardized biennial reporting to track annual progress toward net-zero targets rather than focusing solely on a single target year.

The report analyzes the first wave of CSRD climate reports from 93 large EU companies, finding that while limited assurance is standard, many companies are restating or erasing historical data to improve quality. It identifies a trend toward integrating sustainability internal controls with financial systems and notes that while GHG reporting is improving, monetized climate risk and opportunity reporting remain rare. The document also evaluates the adoption of the EU Taxonomy and the reporting of political lobbying and climate-related executive incentives.

The We Mean Business Coalition identifies critical failures in the ESG data ecosystem, noting that historical emissions data is often inadequate for meaningful analysis due to blatant errors and inconsistent reporting. The report categorizes these issues into company-level reporting failures, data provider extraction errors, and structural gaps such as the lack of central repositories and misalignment between GHG and financial reporting boundaries. To resolve these, the authors advocate for the global adoption of ISSB standards, mandatory XBRL tagging, and the alignment of GHG operational boundaries with financial reporting standards.
