200

This type of greenhouse gas has a global warming potential over 80 times stronger than CO₂ over a 20‑year period.

What is methane?

200

This global convention, established in 1987, successfully phased out many ozone‑depleting chemicals like CFCs.

What is the Montreal Protocol?

400

Companies committed to “Scope 3 reductions” are targeting emissions from this part of their operations — the one they don’t directly control.

What is the supply chain?

400

As AI workloads grow, this metric — often expressed in megawatt-hours — measures the total energy used by a data center.

What is energy consumption?

400

Lithium‑ion batteries are considered this type of waste at end‑of‑life due to strict handling and disposal guidelines.

What is hazardous waste?

400

This tipping point refers to the melting of massive ice sheets, which could cause irreversible sea‑level rise.

What is the ice‑sheet collapse tipping point?

400

This biodiversity “hotspot” spans multiple Southeast Asian nations and is one of the most threatened tropical forest regions on Earth.

What is the Coral Triangle?

600

This sustainability strategy aims to ensure a product has value at each stage of its lifecycle, often measured through cradle‑to‑cradle analysis.

What is circularity?

600

This efficiency metric, known as PUE, evaluates how effectively a data center uses power by comparing total facility energy to IT energy.

What is Power Usage Effectiveness?

600

Modern tech manufacturers increasingly measure product impact using LCA, an acronym standing for this comprehensive assessment.

What is Life Cycle Assessment?

600

This planetary boundary, often exceeded by industrial agriculture, relates to the overuse of nitrogen and phosphorus.

What is biogeochemical flows?

600

This term refers to the rate at which a forest stores carbon in its biomass, often expressed in metric tons per hectare.

What is carbon stock?

800

Increasingly adopted by tech firms, this practice prices carbon internally so teams feel the financial impact of emitting greenhouse gases.

What is an internal carbon price?

800

Tech companies increasingly sign PPAs to secure clean power; the acronym stands for this type of long‑term energy contract.

What is a Power Purchase Agreement?

800

This design philosophy encourages companies to build devices that are easier to take apart, repair, and recycle.

What is design for disassembly?

800

This term describes the amount of carbon an ecosystem can absorb before reaching saturation.

What is carbon sequestration capacity?

800

These ocean zones, formed by nutrient pollution, contain so little oxygen that marine life cannot survive.

What are dead zones?

1000

This “market mechanism” allows companies to fund external emissions‑reduction projects to balance their own carbon footprint.

What are carbon offsets?

1000

This advanced cooling technique uses outside air to regulate server temperatures, reducing reliance on traditional HVAC systems.

What is free cooling?

1000

Microchips rely heavily on this rare‑earth element used in magnets, whose mining has major environmental consequences.

What is neodymium?

1000

This climate phenomenon disrupts weather patterns globally by warming surface waters in the central and eastern Pacific Ocean.

What is El Niño?

1000

This atmospheric circulation pattern, also called the Brewer–Dobson circulation, transports ozone from the tropics toward the poles.

What is stratospheric circulation?
