Practical, in-depth guides to help you navigate carbon management.
NCZ Carbon Accounting Starter Guide: Everything UK Businesses Need to Know About Measuring Emissions
A starter guide to carbon accounting for UK businesses: what it is, measured in tCO2e, the three scopes with Scope 3 often 70-95%, the practical steps of boundaries, activity data, emission factors, calculation and QA, spend versus activity-based data, data challenges, key standards, baseline importance, decarbonisation planning, offsetting and NCZ's four tiers.
Procurement and Supply Chain Carbon Guide
A guide positioning procurement as the decarbonisation lever, since purchased goods and services can exceed 60% of corporate emissions. It covers tiered data collection (spend, activity, supplier-specific), supplier questionnaires, embedding carbon into category management and tenders, supplier segmentation and support, digital tools, capability building, and a four-stage maturity model.
THE NCZ CERTIFICATION FRAMEWORK: Building Credible Pathways to Net Zero
Sets out NCZ's staged certification pathway: Blue (modelled estimate), Silver (self-reported), Gold (specialist-verified ISO 14064 footprint plus a PPN 006 Carbon Reduction Plan) and Platinum (supplier engagement for Scope 3). It also covers optional carbon-neutrality and SBTi-alignment support, the delivery and verification process, and how each level turns carbon management into business value.
Beyond Badges: How NCZ Helps Businesses Strengthen EcoVadis and B Corp Performance
Explains the EcoVadis rating and B Corp certification frameworks and where carbon management fits, noting common shortfalls such as incomplete Scope 3 data, spend-based estimates and no verification. It shows how NCZ's measurement, reduction planning, tiered certification, supplier engagement and transparent reporting strengthen scores across both frameworks.
Carbon Reduction Plan (CRP): A Practical Guide for Organisations
A practical guide to building a credible Carbon Reduction Plan meeting PPN 006 procurement expectations. It covers why CRPs matter commercially and legally, the core components, an accelerated preparation checklist, the compliant-versus-credible distinction, common pitfalls, and how NCZ links CRP requirements to reduction actions and SBTi and ISO 14064 pathways.
Bridging Compliance and Climate Strategy: SBTi and ESOS Explained
Explains how the voluntary SBTi and mandatory ESOS frameworks complement each other, with ESOS energy-audit data informing SBTi target-setting. It details SBTi's purpose, structure and target-setting including the SME route, ESOS requirements, Phase 4 updates and net zero alignment, and how NCZ integrates both into one cohesive framework.
Demystifying Carbon Accounting: The 10 Most Common Questions Businesses Ask
Answers the ten questions UK businesses most commonly ask, from what carbon accounting is and the three scopes to carbon neutral versus net zero, why offsets cannot replace reduction, timelines, UK regulations, setting baselines, common reporting mistakes, how to start a net zero journey and the business case, all mapped to NCZ's certification tiers.
CDP: Disclosure, Risk Management, and Investor Expectations
Explains CDP, the global environmental disclosure system with over 23,000 organisations reporting in 2024, covering its climate, water and forests themes, the business case, the questionnaire and A-to-D scoring, links to climate risk, SBTi and net zero, supply-chain disclosure, how investors and policymakers use the data, common challenges, best practices and NCZ's support.
Carbon Offset Buyer’s Guide
A buyer's guide to high-quality carbon offsets, distinguishing avoidance from removal credits and detailing credibility criteria: additionality, permanence, measurability, verification, no double counting and reputable standards. It covers market red flags, offsetting's place after reduction, how many offsets to buy, project selection, pricing, permissible claims and NCZ's support.
Science Based Targets Initiative (SBTi): The Gold Standard for Corporate Climate Credibility
Explains the SBTi, a partnership of CDP, UNGC, WRI and WWF, as the leading framework for validating 1.5°C-aligned corporate targets. It covers why it matters, the five-step target process, scope emissions, target-setting methods, the Corporate Net Zero Standard (reduce at least 90%, offset no more than 10%), common challenges, benefits and how NCZ supports the journey.
10 Common Carbon Reporting Mistakes and How to Avoid Them
Sets out ten common carbon-reporting mistakes and their fixes: treating reporting as one-off, ignoring Scope 3, uncautious spend-based data, inconsistent boundaries and baselines, outdated conversion factors, confusing offsetting with reduction, double counting, poor documentation, sidelining procurement, and skipping verification, anchored in GHG Protocol, ISO 14064, CDP and SBTi guidance.
