Below are sample questions representative of the exercises included on this worksheet and related 8.66 Human–Environment Interaction and Sustainability skill assessments:

Problem 1Difficulty: Mastery

A new wind project for Redstone Steppe would cause about 385 thousand tons of CO2e during manufacturing and construction. Once operating, it would avoid about 25 thousand tons of CO2e per year by replacing fossil electricity.

About how many years would it take for the project to 'pay back' its construction emissions?

AAbout 9625 years, by multiplying instead of dividing (in Redstone Steppe).

B0 years, because building projects never cause any emissions in Redstone Steppe.

CAbout 0.06 years, by flipping the ratio (in Redstone Steppe).

DAbout 15.4 years (construction emissions divided by annual avoided emissions) (in Redstone Steppe).

Solution & Explanation:Payback time compares upfront emissions to annual savings: payback = build / annual_savings. After that many years, the avoided emissions exceed the construction footprint.

Problem 2Difficulty: Mastery

Glacier Basin generates 447 tons of waste per week. It currently diverts 44% through recycling. The new goal is 87% diversion. Audits show about 38% of the waste stream is compostable organics.

If the city launches organics composting, what minimum amount of compostables (tons/week) must be successfully diverted to reach the goal (assume recycling stays the same)?

A0 tons/week, because adding a program never changes diversion in Glacier Basin.

BAt least about 170 tons/week, because all compostables must be diverted even if the goal increase is smaller (in Glacier Basin).

CAt least about 192 tons/week of organics must be diverted (because diversion must rise by that amount) (in Glacier Basin).

DAt least about 389 tons/week, because the goal is the total diversion, not the increase (in Glacier Basin).

Solution & Explanation:Compute current diverted tons and goal diverted tons, then subtract to find the increase needed. Compare that increase to the available compostable fraction to see if the goal is achievable.

Problem 3Difficulty: Mastery

Willow Coast estimates transportation emissions at 6 tons CO2 per person per year in car-dependent suburbs and 3 tons CO2 per person per year in transit-rich neighborhoods. A plan would shift 124,000 residents from new suburbs to housing near frequent transit.

About how many tons of CO2 per year could be avoided from transportation if the shift happens as planned?

AAbout 372 tons per year, by forgetting to convert thousands of people to people (in Willow Coast).

BAbout 372,000 tons per year (difference per person times 124,000 people) (in Willow Coast).

C0 tons per year, because where people live never affects travel emissions in Willow Coast.

DAbout 1,116,000 tons per year, by adding the two rates instead of comparing them (in Willow Coast).

Solution & Explanation:Compute avoided emissions as (suburb rate - transit rate) * number of people. Converting 124,000 to people is key.
