Fundamentals of Sustainability and ESG

  • Brundtland definition (1987): development meeting present needs without compromising future generations' ability to meet theirs.

  • Three ESG pillars: Environmental (emissions, water, biodiversity), Social (labor, safety, community), Governance (board, ethics, disclosure).

  • Triple bottom line (Elkington): People, Planet, Profit - performance reported across all three, not profit alone.

  • Materiality: an issue is material if it can reasonably affect enterprise value or stakeholder decisions; SASB/ISSB emphasize financial materiality, GRI emphasizes impact materiality.

  • Planetary boundaries (Rockström): nine Earth-system limits; climate change, biosphere integrity, biogeochemical flows, and land-system change are currently most exceeded.

  • SDGs: 17 goals, 169 targets, adopted 2015 with a 2030 horizon; companies map contributions by goal and target, not by logo.

  • ESG ratings diverge because agencies use different scopes, weights, and materiality maps; correlation between major raters is often only moderate.

  • Greenwashing: a claim that overstates environmental benefit; enforcement routes include advertising law, securities disclosure rules, and EU Green Claims scrutiny.

Climate Science, GHG Accounting, and Reporting

  • Greenhouse gases under the Kyoto/GHG Protocol basket: CO2, CH4, N2O, HFCs, PFCs, SF6, NF3.

  • GWP converts non-CO2 gases to CO2e: GWP-100 for CH4 is about 28 (AR5) or 27–30 (AR6); use one consistent GWP set and state it.

  • Scopes: Scope 1 direct fuel/process emissions; Scope 2 purchased electricity/heat; Scope 3 all other value-chain emissions (15 categories).

  • Scope 2 dual reporting: location-based uses grid average emission factor; market-based uses contractual instruments such as RECs or PPAs.

  • Core formula: emissions (tCO2e) = activity data × emission factor × GWP; document factor source and year.

  • Organizational boundary: equity share or control (financial or operational) approach; consolidation approach must be disclosed and applied consistently.

  • Setting targets: base year, target year, scope coverage, and boundary; SBTi near-term targets require roughly 4.2%/yr linear reduction for 1.5 °C alignment.

  • Reporting frameworks: ISSB IFRS S1/S2, GRI, CDP disclosure, TCFD-aligned governance/strategy/risk/metrics structure; CSRD/ESRS in the EU.

Sustainable Finance, Green Bonds, and ESG Investing

  • Green bond use-of-proceeds: allocation to eligible green projects, project evaluation and selection, management of proceeds (ring-fenced or tracked), plus reporting.

  • ICMA Green Bond Principles and Sustainability-Linked Bond Principles are voluntary market standards; SLBs tie coupon step-ups to KPI/SPT achievement.

  • External review types: second-party opinion, verification, certification (e.g., Climate Bonds Standard), and rating.

  • EU Taxonomy: substantial contribution to one of six environmental objectives, do-no-significant-harm to the others, plus minimum social safeguards.

  • Greenium: the yield concession green bonds may command versus conventional equivalents; evidence is issuer- and market-dependent, often a few basis points.

  • ESG integration approaches: negative screening, norms-based screening, best-in-class, thematic, impact investing, and active stewardship/voting.

  • Transition finance funds high-emitting sectors' decarbonization; credibility depends on credible targets, capex alignment, and disclosed milestones.

  • Principal–agent and greenwashing risk: verify fund labels against holdings; SFDR classifies products as Article 6, 8, or 9.

Environmental Management, Circular Economy, and Resource Efficiency

  • ISO 14001 uses Plan–Do–Check–Act: environmental policy, aspects and impacts register, legal register, objectives, operational controls, internal audit, management review.

  • Significant aspect determination weighs likelihood, severity, regulatory exposure, and stakeholder concern; significant aspects drive objectives and controls.

  • Waste hierarchy, most to least preferred: prevent, reuse, recycle, recover (energy), dispose.

  • Circular economy (Ellen MacArthur): design out waste and pollution, keep products and materials in use, regenerate natural systems.

  • Material flow metrics: material intensity (mass per unit output), recycled content %, product circularity, and landfill diversion rate.

  • Life-cycle assessment stages: goal and scope, inventory (LCI), impact assessment (LCIA), interpretation; functional unit is the basis of comparison.

  • Extended producer responsibility shifts end-of-life cost to producers; eco-design rules target repairability, durability, and recycled content.

  • Water and biodiversity tools: water footprint (blue, green, grey), water stress screening, and mitigation hierarchy (avoid, minimize, restore, offset).

Social Sustainability, Labor Practices, and Community Impact

  • ILO core conventions cover freedom of association and collective bargaining, forced labor, child labor, discrimination, and occupational safety and health.

  • Human rights due diligence (UNGP): policy commitment, impact assessment, integration into processes, tracking, and remediation; applies across the value chain.

  • Salient human rights issues are those most severe or likely to be negatively affected by the business, prioritized by severity over leverage alone.

  • Labor metrics: turnover, lost-time injury frequency rate (LTIFR = lost-time injuries × 1,000,000 / hours worked), gender pay gap, living wage gap.

  • Living wage differs from minimum wage: it reflects cost of a decent standard of living in a specific location; benchmarks include Anker methodology.

  • Community impact tools: stakeholder mapping, grievance mechanisms, free prior informed consent (FPIC) for Indigenous peoples, and social license to operate.

  • Supply chain social risk screening: tier-1 vs sub-tier visibility, audit fatigue, and worker voice channels such as anonymous grievance hotlines.

  • Social bond principles mirror green bonds: target populations, use of proceeds, and measurable social outcome reporting.

Governance, Ethics, and Compliance

  • Board duties: duty of care and duty of loyalty; independence, committee structure (audit, risk, remuneration, sustainability), and skills matrix.

  • Separation of chair and CEO, board diversity, and overboarding limits are common governance quality indicators.

  • Anti-bribery management: ISO 37001; FCPA prohibits bribery of foreign officials and requires books-and-records accuracy; UK Bribery Act covers commercial bribery too.

  • Whistleblowing program elements: multiple confidential channels, non-retaliation policy, triage and investigation protocol, and audit committee oversight.

  • Conflicts of interest: identify, disclose, recuse, or manage; related-party transactions require independent review and disclosure.

  • Compliance program components: code of conduct, risk assessment, training, third-party due diligence, monitoring, and discipline.

  • Tax transparency and lobbying disclosure are governance issues; misalignment between climate lobbying and stated climate policy is a common flag.

  • Data ethics and cybersecurity oversight: board-level accountability, incident response, and privacy compliance (e.g., GDPR lawful basis).

Green Project Management and Risk Assessment

  • Project charter for green projects should state the environmental objective, baseline, and quantified expected impact (e.g., tCO2e avoided per year).

  • Additionality: the claimed benefit must exceed business-as-usual; without it, an emission reduction would have happened anyway.

  • Risk register structure: risk description, cause, consequence, likelihood, impact, score, owner, mitigation, residual risk.

  • Risk categories for green projects: regulatory/permit, technology performance, weather/resource variability, supply chain, financing, reputational, and measurement risk.

  • MRV (monitoring, reporting, verification): define metrics, data sources, frequency, QA/QC, and independent verification before claiming outcomes.

  • Avoided-emissions accounting: baseline scenario, project scenario, leakage (emissions shifted outside the boundary), and permanence/durability of reductions.

  • Stakeholder engagement plan: identify affected parties, engagement level (inform/consult/involve), timeline, and grievance route.

  • Green procurement: specify environmental criteria in tender evaluation, verify supplier claims, and include contract KPIs with remedies.
