What is a 'carbon footprint report' in IT vocabulary?
Carbon footprint report for IT: measures Scope 1 (on-site fuel), Scope 2 (purchased electricity for data centers), and Scope 3 (hardware manufacturing, employee devices, supply chain). Typically measured in CO2 equivalent (CO2e), expressed as tonnes per year. Used for: setting reduction targets, tracking progress, ESG disclosures (GRI, TCFD, CDP frameworks).

What is 'net zero' vs. 'carbon neutral' in sustainability vocabulary?
Carbon neutral: emit X tonnes of CO2, buy X tonnes of offsets — net math is zero but emissions still occur. Net zero: reduce emissions by 90%+ (Science Based Targets Initiative threshold), then remove the remaining ~10%. Net zero is considered more credible because it requires actually cutting emissions rather than just offsetting them.

What is a 'PUE' (Power Usage Effectiveness) in data center vocabulary?
PUE measures data center infrastructure efficiency: total power consumed (including cooling, lighting, UPS losses) divided by power to IT equipment. PUE 1.0 = perfect. Hyperscalers (Google, Meta) achieve ~1.1. Average enterprise data center: ~1.5-2.0. PUE is a useful but limited metric — it does not measure what the IT equipment is actually doing with its power.

What is 'GreenOps' in cloud and IT vocabulary?
GreenOps (analogous to FinOps for cost): applying operational rigor to sustainability. GreenOps practices: continuous carbon monitoring (cloud carbon footprint tools), carbon-awareness in deployment decisions, right-sizing for sustainability, scheduled workload shifting, team accountability for carbon metrics alongside cost metrics. GreenOps treats carbon as a resource to be managed, not just measured.

What is 'Science Based Targets' (SBTi) in sustainability vocabulary?
SBTi (sciencebasedtargets.org): companies commit to targets aligned with climate science (limit warming to 1.5C). For tech: typically 50% reduction in Scope 1+2 emissions by 2030, and 25-30% reduction in Scope 3 by 2030. SBTi validates and publishes commitments. Investors and customers increasingly require SBTi commitment as a credibility signal.

Sarah (Senior DevOps Engineer) posted this to Slack: 'Just ran a quick audit of our AWS deployments. Seems like we're using a lot of older EC2 instances – high CPU utilization and minimal scaling. Thinking about decommissioning them. What does 'idle power' refer to in this context?',
Idle power specifically refers to the energy consumed by servers when they are switched on but not actively processing requests or performing computations. This is a significant contributor to data center carbon emissions because servers constantly draw power even when idle. Options A and D describe active usage; option C is a broader lifespan metric, while option B represents the precise definition of idle power.

You're writing the description for a pull request to migrate a legacy application to a more sustainable cloud provider. The PR includes an estimate of a 30% reduction in carbon emissions. Which phrase best describes this reduction?
While '30% reduction' sounds straightforward, it's crucial to understand that sustainability reporting often uses percentage changes relative to a baseline. This allows for comparison across different systems and accounts for varying levels of initial emissions. Options A describes hardware impact; B is too broad; and D focuses on the immediate switch, neglecting ongoing efficiency gains.

Mark (Sustainability Analyst) sent you this API response from a carbon accounting tool: `{"metric": "Scope 3 Emissions", "value": 125.7, "unit": "tonnes CO2e", "timestamp": "2024-10-27T14:30:00Z"}`. What does 'Scope 3 Emissions' primarily represent?
Scope 3 emissions encompass indirect greenhouse gas emissions that occur in a company's value chain—this is the most important distinction. These often include emissions from suppliers, transportation, and even customer usage of products or services. While relevant to overall sustainability, Scope 1 and 2 are direct emissions.

During a standup meeting, David (Lead Architect) says: 'We're aiming for PUE of 1.4 in our new data center design.' What does 'PUE' stand for?
PUE stands for Power Usage Effectiveness, which is a critical metric in data center sustainability reporting. It's defined as the ratio of total facility power (IT equipment + cooling) to IT equipment power. A lower PUE indicates greater energy efficiency – meaning less energy is wasted on cooling.

You're reviewing a technical report discussing carbon reduction strategies for a software development project. The report mentions 'Science Based Targets' (SBTi). What is the primary purpose of SBTi?
SBTi (Science Based Targets initiative) is a framework that helps companies set emission reduction targets aligned with what's scientifically necessary to limit global warming to 1.5°C or 2°C above pre-industrial levels. It's a validation process ensuring ambitious and credible climate action, not just vague promises.
