More information on LEED Certification by the U.S. Green Building Council: https://www.usgbc.org/leed + LEED (Leadership in Energy and Environmental Design) is the world’s most widely used green building rating system. LEED certification provides a framework for healthy, highly efficient, and cost-saving green buildings, which offer environmental, social and governance benefits. LEED certification is a globally recognized symbol of sustainability achievement, and it is backed by an entire industry of committed organizations and individuals paving the way for market transformation.

LEED is for all project types and phases, including new construction, core and shell, interior fit-outs, operations and maintenance, neighborhoods and cities.

LEED is holistic. As a framework, it addresses everything from energy and water use to materials selection, managing waste and indoor environmental quality through a series of credit categories tailored for each rating system. To achieve LEED certification, a project must first complete all prerequisites and then earn points by selecting and satisfying credit requirements. Projects go through a verification and review process by GBCI and are awarded points that correspond to a level of LEED certification: Certified, Silver, Gold and Platinum.

• Platinum – 80+ points earned
• Gold – 60-79 points earned
• Silver – 50-59 points earned
• Certified – 40-49 points earned

LEED v5 is the newest version of LEED. It marks a transformative milestone in the built environment’s alignment with a low-carbon future and addresses critical imperatives such as equity, health, ecosystems and resilience.

LEED is a holistic system that doesn’t simply focus on one element of a building such as energy, water or health, rather it looks at the big picture factoring in all of the critical elements that work together to create the best building possible. In fact, 35% of the credits in LEED are related to climate change, 20% of the credits directly impact human health, 15% of the credits impact water resources, 10% of the credits affect biodiversity, 10% of the credits relate to the green economy, 5% of the credits impact community and 5% of the credits impact natural resources.

EMR Additional Notes:

• Carbon Dioxide (CO2):
  • The primary greenhouse gas emitted through human activities. Carbon dioxide enters the atmosphere through the burning of fossil fuels (coal, natural gas, and oil), solid waste, biomass (e.g. wood), and also as a result of certain industrial chemical reactions (e.g. cement production).
  • Carbon dioxide is removed from the atmosphere (or “sequestered”) when it is absorbed by plants as part of the biological carbon cycle and through ocean absorption and geological processes. In climate accounting, however, “carbon sequestration” generally refers to the removal and storage of carbon in a reservoir; natural uptake through the carbon cycle is not necessarily classified as anthropogenic carbon dioxide removal (CDR).
  • CO₂ is naturally part of the carbon cycle, but human activities have significantly increased its concentration in the atmosphere.
• Biogenic Carbon Dioxide (CO2):
  • Biogenic CO₂ and fossil-derived CO₂ are chemically identical molecules.
  • The distinction is not chemical, but source-based:
    • Biogenic carbon: CO₂ released from organic materials such as plants, wood, soil, and biomass that were recently part of the natural carbon cycle. Its accounting treatment depends on the applicable carbon-accounting methodology and whether the carbon is considered part of the contemporary biogenic carbon cycle.
    • Fossil carbon: CO₂ released from fossil fuels (coal, oil, gas), which were stored underground for millions of years. This introduces additional carbon into the active atmospheric carbon cycle and is therefore generally treated as fossil CO₂ emissions.
• CO2e (Carbon Dioxide Equivalent):
  • CO₂e means “carbon dioxide equivalent”.
  • It is a standardized climate metric used to express the total climate impact of multiple greenhouse gases in a single standardized unit.
  • CO₂e converts all greenhouse gases (such as methane and nitrous oxide) into the amount of CO₂ that would have the same integrated radiative forcing / climate impact over a defined time period using a specified Global Warming Potential (GWP) value.
  • Formula: CO₂e = mass of gas × Global Warming Potential (GWP)
  • Carbon dioxide equivalents are commonly expressed as million metric tonnes of carbon dioxide equivalents, abbreviated as MtCO₂e or Mt CO₂-eq; “MMTCDE” is used in some datasets but is not the preferred general notation.
  • The carbon dioxide equivalent for a gas is derived by multiplying the tonnes of the gas by the associated GWP: CO₂e = mass of gas × GWP.
  • For example, the GWP for methane is approximately 27–30 under IPCC AR6 depending on the methane source and accounting convention, while the 100-year GWP for nitrous oxide is 273. This means that emissions of 1 million metric tonnes of methane and nitrous oxide respectively would correspond to approximately 27–30 and 273 million metric tonnes of CO₂e under those GWP assumptions.
• Carbon Footprint:
  • There is no universally agreed definition of what a carbon footprint is.
  • The most widely used definition (GHG Protocol) describes it as: “The total set of greenhouse gas (GHG) emissions caused directly and indirectly through an organization’s operations and value chain.” The GHG Protocol generally refers to corporate GHG inventories and Scope 1, 2 and 3 emissions rather than prescribing one universal definition of “carbon footprint.”
  • A carbon footprint is the total amount of greenhouse gas (GHG) emissions caused directly and indirectly by an individual, organization, product, or activity.
  • It is typically measured in CO₂e.
• Decarbonization:
  • Reduction of carbon dioxide emissions through the use of low-carbon energy sources and improved efficiency, with the goal of reducing overall greenhouse gas emissions. More broadly, decarbonization refers to reducing the carbon intensity and/or absolute greenhouse-gas emissions of an economy, sector, organization, product, or process, potentially including CO₂ removal for residual emissions.
  • Decarbonization typically refers to system-wide transition, not only emission reduction at a single source.
• Carbon Credits or Carbon Offsets:
  • Carbon credits are tradable certificates representing the verified reduction or removal of one metric tonne of CO₂e, generally generated by a specific project or activity; terminology and quality criteria vary between carbon markets.
  • They are part of cap-and-trade systems, where:
    • A cap limits total emissions
    • Companies receive or buy emission allowances
    • Excess allowances can be traded
  • Offsets are often linked to external projects that reduce or remove emissions (e.g. reforestation, renewable energy). A carbon offset is generally a credit representing a reduction or removal outside the entity’s own emissions boundary that may be used to compensate for emissions, subject to the applicable programme or claim rules.
  • Carbon credits and emission allowances should not be treated as synonymous: an allowance is a regulated authorization to emit under a cap-and-trade system, whereas a credit/offset generally represents a quantified emission reduction or removal.
• Carbon Capture and Storage (CCS) – Carbon Capture, Utilisation and Storage (CCUS):
  • CCS involves capturing CO₂ emissions from industrial processes or other concentrated sources and storing them permanently in geological formations (e.g. underground reservoirs).
  • CCUS adds a utilization step, where captured CO₂ is reused as a feedstock (e.g. fuels, chemicals, building materials). More precisely, CCUS refers to carbon capture followed by utilization and/or storage; utilization does not necessarily result in permanent carbon storage.
  • CCS = capture + geological storage; CCUS = capture + utilization and/or storage.
• Carbon Dioxide Removal (CDR) or Durable Carbon Removal: 
  • CDR refers to methods that actively remove CO₂ from the atmosphere and store it for long periods in geological, biological, or mineral form. CDR specifically requires an anthropogenic activity that removes atmospheric CO₂ and durably stores it in geological, terrestrial, ocean, or product reservoirs.
  • Examples include:
    • Direct Air Capture (DAC)
    • Bioenergy with Carbon Capture (BECCS)
    • Enhanced Rock Weathering (ERW)
  • CDR creates net negative emissions when removal exceeds emissions. A CDR activity itself can provide a net removal only when the total emissions associated with the removal process are lower than the amount of CO₂ durably removed and stored.
• Direct Air Capture (DAC): 
  • Technologies that extract CO2 directly from the atmosphere at any location, unlike carbon capture which is generally carried out at the point of emissions, such as a steel plant. DAC can capture CO₂ from ambient air regardless of where the original emissions occurred; it is distinct from point-source carbon capture.
  • Constraints like costs and energy requirements as well as the potential for pollution make DAC a less desirable option for CO2 reduction. Its larger land footprint when compared to other mitigation strategies like carbon capture and storage systems (CCS) also put it at a disadvantage. However, DAC is a potential carbon-removal technology rather than simply a CO₂-reduction technology, and its climate benefit depends strongly on the energy source, capture efficiency, permanence of storage, and lifecycle emissions.
• Direct Air Capture and Storage (DACCS):
  • Climate technology that removes carbon dioxide (CO2) directly from the ambient atmosphere using large fans and chemical processes to bind with the CO2. The captured CO₂ is then transported and durably stored, typically in geological formations.
  • DACCS is therefore a specific form of CDR: DAC + durable CO₂ storage.
• Bioenergy with Carbon Capture and Storage (BECCS):
  • Technology that generates energy from biomass while capturing and storing the resulting CO₂.
  • Because biomass absorbs CO₂ while growing, BECCS can result in net negative emissions. It can result in net negative emissions when the full lifecycle emissions—including biomass production, harvesting, transport, processing, energy use, and capture/storage—are sufficiently lower than the amount of biogenic CO₂ durably removed from the atmosphere.
• Enhanced Rock Weathering (ERW):
  • Carbon dioxide removal (CDR) technique that accelerates the natural process of rock weathering by grinding silicate rocks into dust and spreading it on land, typically agricultural fields. This process enhances reactions with water and atmospheric CO₂, converting dissolved carbon into bicarbonate and, ultimately, carbonate minerals or transporting dissolved inorganic carbon to aquatic systems, where it can be stored over long timescales.
  • Its effectiveness and permanence depend on rock type, particle size, weathering rates, transport pathways, soil and water chemistry, and the emissions associated with mining, grinding, and transporting the rock.
• Limits of Carbon Dioxide Storage: 
  • Carbon storage is not endless; the Earth’s capacity for permanently storing vast amounts of captured carbon, particularly in geological formations, is limited, potentially reaching a critical limit of 1,460 gigatonnes at around 2200, though storage durations vary significantly depending on the method, from decades for some biological methods to potentially millions of years for others like mineralization. Estimates of geological storage capacity vary widely and depend on geology, reservoir characteristics, storage efficiency, infrastructure, economics, regulation, monitoring, and permanence.
  • While some methods offer very long-term storage, the sheer volume needed to meet climate targets requires scaling up storage significantly beyond current capacity, raising concerns about the available volume over time. The practical constraint is therefore better described as the need to develop sufficient safe, permanent, economically and technically accessible storage capacity rather than a single known global physical limit.
• Carbon Impregnation: 
  • Carbon impregnation is the process of treating activated carbon with chemical agents (such as metals, acids, or bases) to enhance its ability to adsorb specific, hard-to-remove pollutants. By loading substances like silver, sulfur, or potassium hydroxide into its pores, this material combines physical adsorption with chemical reaction for improved, targeted filtration in water and air. This is a materials engineering process, not a climate accounting concept.

 

• Global Warming: 
  • Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. Global warming refers specifically to the long-term increase in Earth’s average surface temperature; climate change is the broader term encompassing associated changes in climate systems, including precipitation, extremes, sea level, and ecosystems.
• Global Warming Potential (GWP): 
  • A measure of how much heat a greenhouse gas contributes to climate warming relative to CO₂ over a specific time period (commonly 100 years).
  • CO₂ has a GWP of 1.
  • GWP is the scientific basis for converting gases into CO₂e.
  • GWP was developed to allow comparisons of the global warming impacts of different gases. The numerical GWP depends on the selected IPCC assessment, time horizon, and, for some gases such as methane, the emission source and accounting convention.
• Greenhouse Gas (GHG):
  • Any gas that absorbs and emits infrared radiation in the atmosphere, contributing to the greenhouse effect.
  • Main GHGs include:
    • CO₂
    • Methane (CH₄)
    • Nitrous oxide (N₂O)
    • Fluorinated gases such as HFCs, PFCs, SF₆ and NF₃
  • Water vapor is a GHG but is not directly controlled by human emissions at scale. It is primarily a feedback in the climate system rather than a direct target of conventional anthropogenic GHG inventories.

• GHG Protocol Corporate Standard Scope 1, 2 and 3: https://ghgprotocol.org/ + The GHG Protocol Corporate Accounting and Reporting Standard provides requirements and guidance for companies and other organizations preparing a corporate-level GHG emissions inventory. The Corporate Standard itself is voluntary, although companies may be required by applicable legislation or regulation to report using the GHG Protocol or equivalent requirements.
  • Scope 1: Direct emissions:
    • Direct emissions from company-owned and controlled resources. In other words, emissions are released into the atmosphere as a direct result of a set of activities, at a firm level. More precisely, Scope 1 covers direct GHG emissions from sources that are owned or controlled by the reporting organization.
    • It is divided into four categories:
      • Stationary combustion (e.g from fuels, heating sources). All fuels that produce GHG emissions must be included in scope 1. This applies when the combustion source is owned or controlled by the reporting organization.
      • Mobile combustion is all vehicles owned or controlled by a firm, burning fuel (e.g. cars, vans, trucks). The increasing use of “electric” vehicles (EVs), means that some of the organisation’s fleets could fall into Scope 2 emissions. For example, fuel combustion in an owned/controlled vehicle is Scope 1, whereas electricity purchased to charge an EV is generally Scope 2; an EV itself does not create Scope 2 emissions—the purchased electricity does.
      • Fugitive emissions are leaks from greenhouse gases (e.g. refrigeration, air conditioning units). It is important to note that refrigerant gases are not uniformly “a thousand times more dangerous” than CO₂; some refrigerants have GWPs of hundreds or thousands of times that of CO₂, while others have much lower values. Companies are encouraged to report these emissions.
      • Process emissions are released during industrial processes, and on-site manufacturing (e.g. production of CO2 during cement manufacturing, factory fumes, chemicals). These are direct emissions resulting from physical or chemical processes other than fuel combustion, such as calcination in cement production..
  • Scope 2: Indirect emissions – owned:
    • Indirect emissions from the generation of purchased energy, from a utility provider. In other words, all GHG emissions released in the atmosphere, from the consumption of purchased electricity, steam, heat and cooling. Scope 2 covers indirect GHG emissions associated with the generation of purchased or acquired electricity, steam, heat, and cooling consumed by the reporting organization; “owned” is therefore misleading because the emissions source is owned or controlled by another entity.
    • For most organisations, electricity will be the unique source of scope 2 emissions. Simply stated, the energy consumed falls into two scopes: Scope 2 covers the electricity consumed by the end-user. Scope 3 covers the energy used by the utilities during transmission and distribution (T&D) losses. More precisely, Scope 2 covers the generation-related emissions associated with purchased electricity, not the physical electricity itself. T&D losses are generally accounted for in Scope 3 Category 3 for an energy consumer that does not own the T&D system, although the treatment can vary depending on ownership and accounting circumstances.
  • Scope 3: Indirect emissions – not owned:
    • Indirect emissions – not included in scope 2 – that occur in the value chain of the reporting company, including both upstream and downstream emissions. In other words, emissions are linked to the company’s operations. According to the GHG protocol, scope 3 emissions are separated into 15 categories. Scope 3 therefore captures other indirect value-chain emissions, upstream and downstream, across the 15 defined categories of the Scope 3 Standard.

 

 

 

• Heat Exchangers, Heat Pumps, Air Source Heat Pump (ASHP), Hydronics, Geothermal Heating – Cooling & Chillers:
  • Heat Exchangers – Heat Transfer Foundation:
    • Used to transfer heat from one medium to another. These media may be a gas, liquid, or a combination of both. The media may be separated by a solid wall to prevent mixing or may be in direct contact. Heat exchangers are required to provide heating and/or cooling to meet a process requirement.
    • In HVAC, heat exchangers are used to transfer heat between the indoor and outdoor air streams while keeping them physically separated as a means of cooling or heating indoor air. heat exchangers are components; systems performing heating/cooling cycles are heat pumps, not the heat exchangers themselves.
    • Gasketed heat exchangers are compact, highly efficient devices used to transfer heat between two fluids without mixing them. They consist of a series of corrugated metal plates fitted with elastomeric gaskets that seal the channels and direct the fluids into alternate pathways. This design creates high turbulence, maximizing heat transfer efficiency while maintaining a significantly smaller footprint than traditional shell-and-tube units.
  • Heat Pumps – Thermodynamic Systems (Energy Transfer Devices):
    • Use electricity to transfer heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house.  During the cooling season, heat pumps move heat from your house into the  outdoors. Because they transfer heat rather than generate heat, heat pumps can efficiently provide comfortable temperatures for your home. They operate on a vapor-compression refrigeration cycle (similar to air conditioners and chillers).
  • Air Source Heat Pump (ASHP) – Thermodynamic Systems (Energy Transfer Devices):
    • Heating and cooling system that extracts heat from the outside air and transfers it to a building’s interior for heating, or reverses the process to cool the building. ASHPs are a low-carbon alternative to traditional heating systems like gas boilers or oil furnaces. They are efficient because they transfer heat rather than generating it, typically providing a coefficient of performance (COP) of ~2–4 under typical conditions (can vary significantly with temperature).
    • The only difference between a heat pump and a chiller is that one is designed to remove heat from a space or process stream, making it cooler and rejecting heat to the environment, while the other is designed to extract heat from the environment and use it to provide useful heat.
  • Chillers – Cooling Systems (Heat Removal Focus):  
    • Mechanical systems that remove heat from a building’s liquid coolant, typically water, and transfer it to another location to cool the air and maintain comfort. Unlike traditional systems that might cool air directly, chillers generate chilled water that circulates through air handling units (AHUs) within the space to absorb heat, making them essential for cooling large commercial or industrial buildings.
    • Chillers and heat pumps use similar thermodynamic cycles, but are designed and optimized for different applications (process/central cooling vs reversible heating/cooling).
    • The only difference between a heat pump and a chiller is not strictly the function, but primarily the design intent and system integration:
      • A chiller is typically designed to remove heat from a space or process (cooling-focused).
      • A heat pump is designed to provide useful heating (and often reversible cooling).
  • Hydronics – Distribution Systems (Energy Transport):
    • Systems of heating or cooling that involves transfer of heat by a circulating fluid (such as water or vapor) in a closed system of pipes. Hydronic systems distribute thermal energy (heating or cooling) but do not generate it themselves.
  • Geothermal Heating and Cooling Systems – Renewable / Ground-Based Systems:  
    • Take advantage of the relatively stable temperature underground using a piping system, commonly referred to as a “loop.” Water or a water-antifreeze mixture circulates in the loop to exchange heat between your home, the ground source heat pump, and the earth, providing geothermal heating, cooling, and hot water at very high efficiencies (often higher than ASHPs).
