Understanding Eco

Build Presets

One-click starter kits are every table associated with a specialty, plus the right-sized power and water infrastructure it needs (fewest, most appropriately-sized units, not lots of small ones). Adds to your Build List below rather than replacing it. Basic kits contain tables you can build with equal and earlier tier profession's tables. The full build list includes tables from all tiers, including those you may not have unlocked yet.

Already have some of what you need? Add it here. The calculator subtracts it from demand at the right point in the chain (e.g. having Advanced Circuits on hand means less Copper Wiring, Gold Wiring, etc. needed to craft your item).

Data parsed directly from the Eco server's recipe definitions (943 craftable items, 67 crafting stations, 60 with an Upgrade Module slot). A few notes: generic material categories (e.g. "any wood," "any vegetable") are resolved to one representative item for calculation purposes. Recipes with multiple simultaneous outputs (e.g. butchering an animal for meat + hide + wool) are tracked under their first-listed output only, so co-products of those recipes are treated as gathered/raw rather than craftable. This mainly affects food/hunting items, not building materials or tech. Reusable containers/molds (Clay Mold, Ceramic Mold, Barrel) are credited back automatically when a recipe returns them, so they're not double-counted as fully consumed. This is exact for Clay/Ceramic/Wooden Mold reuse and the Petroleum/Barrel refining loop; a handful of rarer byproducts (Ashlar stone-cutting scraps, Slag/Sulfur reprocessing) aren't credited due to how they sit in the calculation order, so those are still slightly over-counted. Crafting table upgrades: pick an installed Upgrade Module per station in the sidebar and it will give the proper bonus for the level selected. Ore processing table output doesn't benefit from the upgrade module, so you will not get more crushed by adding a module.

Pollution

Eco tracks two environmental systems, not three as air pollution isn't a separate thing from CO2, it's one of three sources that all feed the same global CO2 total (confirmed directly by the game's own ClimateState fields: LifetimeCO2FromPollution, LifetimeCO2FromAnimals, and LifetimeCO2FromPlants — three contributor streams, one shared pool):

Ground pollution (0–1 scale, spreads outward from a source point) from sewage discharge, dumped mining waste (Tailings), and air pollution mixing with rain. Local and spatial, not part of the CO2 total.
CO2 (measured in PPM, tracked as one global number) is fed by three summed sources: vehicles/chimney-venting buildings (converted from tons), every animal (continuous, positive), and every plant/tree (continuous, negative — a real carbon sink). This one shared total drives global temperature and sea-level effects.

A well-planted forest absorbs CO2. It subtracts from the same pollution pool that is added to by things that pollute. This accounting looks to be global, not local by distance. A forest offsets the world's total CO2, not specifically the pollution from one nearby building. The spread of the smoke from an exhaust pipe is just visual - the CO2 number is a whole-global number.

These are the game's own default values from its shipped server config. A server admin can change any of them, so a specific live server may not match these exactly. All figures below are 1.0× the PollutionMultiplier setting.

Climate Effects: CO2 → Temperature & Sea Level

CO2 starts at a floor of 325 ppm. Temperature and sea level each have their own threshold. If the world crosses it, that effect starts climbing with every additional ppm, up to its own cap.

Effect	Starts at	Rate	Max	Fastest change
Temperature	340 ppm	+1°C per 20 ppm above	+30°C	1.5°C/day
Sea level	420 ppm	+1m per 20 ppm above	+20m	1m/day

Temperature reacts first, since its threshold (340 ppm) is lower than sea level's (420 ppm). A rising world heats up well before the oceans start to climb. 1 ton of CO2 released equals about 1.29 ppm (world modeled at 1.5 kg/m² atmospheric pressure).

Ground Pollution

Sewage: every 1,000 units discharged from a pipe creates 1 unit of ground pollution per hour, right at the discharge point. Sewage is a byproduct of any water-consuming building (Oil Refinery, Laboratory, Blast Furnace, and the power generators that need cooling water).

Tailings: 0.016 ground pollution per tick for every improperly-stored block. Burying it deeper genuinely helps. Tailings pollution halves for every 5 blocks of additional depth. Search the Wiki for Wet Tailings or Tailings for what produces each one.

Acid rain: air pollution and rainfall directly react to create ground pollution. Ground pollution spreads slowly and preferentially downhill into low-lying areas, and lingers (2% dissipates per tick) — noticeably longer than the local air pollution spread effect, which spreads fast between neighboring areas (97%) but clears quickly (5% dissipates per tick).

CO2 Source: Vehicles & Buildings

One of the three streams feeding the global CO2 total (see above), converted from tons into PPM. Rates are tons per hour of active operation (confirmed directly from AirPollutionComponent's own source.It only accumulates while a vehicle is actually being driven or a building is actively crafting, not while idle). Vehicles pollute at a fixed rate regardless of load. Chimney-venting buildings pollute proportional to their own smog output rate (tied to how much fuel they burn).

Source	Type	Tons/Hour (active)

CO2 — Emitters & Absorbers

Every animal in the game continuously emits CO2; every plant and tree continuously absorbs it. Positive values emit, negative values absorb. Per-species rates below are individual; the game caps the combined total across the whole world at +25 ppm/day from all animals and -500 ppm/day from all plants — a heavily forested world has far more carbon-sink capacity than animal populations could ever outweigh.

Pollution Mitigation Talents

Real profession skill-tree talents that change pollution output: some reduce it, a few are tradeoffs that increase it in exchange for a benefit elsewhere (like faster crafting or extraction).

Tailings Pollution Calculator

Each stored block pollutes at 0.016/tick × its own factor (dry Tailings = 2, Wet Tailings = 3. Wet genuinely pollutes 50% more per block, confirmed from the game's own block source), then halves for every 5 blocks of depth below the surface. Add one entry per stockpile, since depth and type can differ between piles, add as many as you need and see the combined total.

For Server Admins — Tuning Pollution Tolerance

World size and atmosphere pressure directly control how much CO2 a world can absorb before hitting the temperature/sea-level thresholds above. The relationship: interior world area (in m²) is (World Width × 10) × (World Length × 10); multiply that by atmosphere pressure (kg/m²) to get the total atmosphere size in tons; then 1,000,000 ÷ atmosphere tons gives you PPM added per ton of net CO2. A bigger world or higher pressure means a bigger atmosphere, which means more tons of pollution needed to move the same PPM. That's more tolerance before the thresholds hit.
