What is GHG Protocol?
The Greenhouse Gas (GHG) Protocol is the world’s most widely used standard for measuring and reporting greenhouse gas emissions. It defines how organisations should classify, calculate, and disclose their emissions across: Scope 1 – direct emissions from owned/controlled sources Scope 2 – indirect emissions from purchased electricity/heat/steam Scope 3 – all other value‑chain emissions (e.g., suppliers, logistics, waste, travel) In the 1990s, companies and governments

Why Governance Is So Important in ESG?
Governance matters in ESG because it’s the “operating system” that makes the E and the S real . Good governance ensures that sustainability is not a slogan but a set of decisions, controls, incentives, and accountability mechanisms that actually influence behaviour. Governance turns intent into action. Environmental and social commitments mean nothing without decision‑rights, data controls, and consequences. Governance allocates accountability. Someone must own the risk,

Permanence?? How stable you are?
What is Permanence? In sustainability (especially in carbon accounting and waste management), permanence refers to how long a material, carbon storage method, or environmental impact remains stable without being reversed . In simple terms: It measures how long something lasts without breaking down, leaking, or being re‑released into the environment . Permanence matters because long‑lasting materials (or carbon storage methods) carry different risks : • Long permanence = go

TPA and Sustainability Investment
What Is TPA — Total Portfolio Approach The Total Portfolio Approach (TPA) is an integrated investment management framework where an investor (such as an asset owner, sovereign wealth fund, pension fund, or endowment) manages the entire portfolio holistically, rather than in isolated asset‑class silos . Instead of focusing on traditional asset classes (equities, bonds, real estate, etc.) separately, a TPA framework considers the total portfolio’s overall risk, return, and lo

Biomass energy? & different accounting treatments?
1. What Is Biomass Energy 🌿 ? Biomass energy refers to energy derived from organic materials — such as wood, agricultural residues, forest waste, animal manure, or dedicated energy crops. It is considered part of the renewable energy mix because the carbon released during combustion can, in theory, be reabsorbed by new plant growth , creating a closed carbon cycle . Examples of biomass energy sources: Wood pellets and forestry residues Agricultural waste (corn stalks, r

Common Green House Gases (GHGs) and their Impact to our environment
Greenhouse gases (GHGs) are gases in the Earth’s atmosphere that trap heat and help keep the planet warm enough to support life. Definition: Greenhouse gases are atmospheric gases that absorb and emit infrared radiation, causing the greenhouse effect — a natural process that warms the Earth’s surface. How It Works: The Sun’s energy reaches Earth as sunlight (shortwave radiation). The Earth absorbs some of this energy and re-emits it as heat (longwave infrared radiation)

Carbon Intensity? and why it matters to us?
Carbon intensity is a measure of how much carbon dioxide (CO₂) (or CO₂-equivalent greenhouse gases) is emitted per unit of output . It shows how efficiently a company, product, or economy generates value while managing its emissions. In business terms, it’s the ratio between GHG emissions and a relevant activity or economic unit , such as revenue, energy produced, or product manufactured. Formal Definition Carbon Intensity = Total GHG Emissions (in CO₂e) ÷ Unit of Outpu

Albedo effect and impact to our temperature
The albedo effect refers to how much sunlight (solar radiation) a surface reflects back into space instead of absorbing. It plays a crucial role in Earth’s climate system . Key Idea Albedo is a measure of reflectivity , expressed as a fraction or percentage. High albedo: More reflection, less absorption (e.g., snow, ice). Low albedo: Less reflection, more absorption (e.g., oceans, forests, asphalt). Example: Typical Albedo Values Surface Type Approx. Albedo Fresh snow 0.
