Emissions on year-end summary don't match the history at the end of the game

[sgitkene]

I think some of the projects' negative emissions are not being counted. I think e.g. DAC may be one of the culprits, as the large discrepancies start appearing with increasing levels of DAC. I attached the entire history too.

[2025] political_capital: 100 -> 4 emissions.as_gtco2eq: 51.579174 -> 54.981224 (seems correct)

[2030] political_capital: 4 -> 0 protected_land: 0.1 -> 0.13333333 emissions.as_gtco2eq: 54.981224 -> 55.31417 (first discrepancy)

[2035] (Forgot to sc) political_capital: 0 -> 8 protected_land: 0.13333333 -> 0.40416664 emissions.as_gtco2eq: 55.31417 -> 39.762833

[2040] political_capital: 8 -> 9 protected_land: 0.40416664 -> 0.56999993 emissions.as_gtco2eq: 39.762833 -> 22.85015 (discrepancy in the single digits and higher from here on out)

[2045] political_capital: 9 -> 189 emissions.as_gtco2eq: 22.85015 -> -0.6647185

[2050] political_capital: 189 -> 210 protected_land: 0.56999993 -> 0.61999995 emissions.as_gtco2eq: -0.6647185 -> -14.41661

[2055] political_capital: 210 -> 364 emissions.as_gtco2eq: -14.41661 -> -24.015253

thanks for the report. I've investigated a bit and have a lead about what could be going on, but hard to be sure right now.

Emissions results under a few different scenarios below...

to make things easier I tried a few runs where I removed the energy usage of DAC.

No DAC
2022=51.6
2025=55.6
2030=62.7
2035=70.1
2040=77.6

DAC, no upgrades
2022=51.6
2025=56.2
2030=63.9
2035=71.3
2040=78.8

DAC, no upgrades, removed DAC energy usage
2022=51.6
2025=54.9
2030=61.2
2035=68.6
2040=76.1

DAC, one upgrade, removed DAC energy usage
2022=51.6
2025=54.9
2030=61.2 Finished
2035=68.6 Upgraded
  then in planning: 67.1 (68.6 - 1.5)
2040=74.6

DAC, two upgrades, removed DAC energy usage
2022=51.6
2025=54.9
2030=61.2 Finished
2035=68.6 Upgraded
  then in planning: 67.1 (68.6 - 1.5)
2040=74.6 Upgraded
  then in planning: 73.1 (74.6 - 1.5)

The console output and the report/planning HUD numbers matched each time. In the last two example s(where I upgraded DAC) the report and console both report 68.6 and then after you go to the next planning screen, the HUD reports 67.1, I'm pretty sure this is just because the upgrade effect (an additional 1.5 emissions reduction) isn't taken into account until after the report.

Does that sound more or less like what might be happening on your end?

I did a run leaving out any projects that said to reduce ghg directly. The only one I took and kept upgrading is DAC. However, I don't think DAC is the culprit anymore. I noticed a discrepancy between the stats screen and the summaries and the console output. It seems a different value is taken at each point. I'm now just pretty certain that something else besides possibly DAC is wrong.

[2035] political_capital: 0 -> 6 protected_land: 0.1 -> 0.33750004 emissions.as_gtco2eq: 41.35248 -> 32.71087

The year end summary indicates 32.0 (0.7 difference from console)

The stats screen has a wildly different number at 24.0Gt.

Not sure if it helps with anything but here the rest of the screenshots of that run as well as the full "history" summary and savegame (as text file exported from storage): run4.zip

when I do the same thing as you (no DAC) and just click ready every cycle, I get the following:

[2025] emissions.as_gtco2eq: 51.579174 -> 55.642757 [2030] emissions.as_gtco2eq: 55.642757 -> 64.04519 [2035] emissions.as_gtco2eq: 64.04519 -> 71.67728 (game over)

The values on the stats screen and reports all match up.

The discrepancies show up when changing the production mix:

2022 stats.

transition 2022-2025 Console:

[2025]
emissions.as_gtco2eq: 51.579174 -> 55.642757

2025 stats.

transition 2025-2030 Console:

[2030]
political_capital: 100 -> 74
emissions.as_gtco2eq: 55.642757 -> 109.67238

2030 stats.

transition 2030-2035. Console:

[2035]
political_capital: 74 -> 50
emissions.as_gtco2eq: 109.67238 -> 136.01736

(Game over)

I think this was due to process mix changes being applied after the report phase so they weren't properly reflected in the report. So this may be fixed now.

[sgitkene]

can't confirm fix. after a hard reload of the page I still get the discrepancies between stats screen and report:

[2025] emissions.as_gtco2eq: 51.579174 -> 55.642757

Now console output and the report show the same, but the stats screen shows a different value:

Stats show 43 Gt emissions.

Interestingly, the emission prediction from last cycle (39.6 Gt) was close to what the future stat screen would read.

In the following cycle, when staging no changes at all, I get numbers that match across the board, except now the console output picks the wrong number as the start:

emissions.as_gtco2eq: 55.642757 -> 48.55009

The console output reads 55.642757 which was what the console output from last cycle was.

This time, the stats read the same as the report and console output for 2030.

Nevermind, the changes you mentioned probably aren't live, I am on a65f7ae

[frnsys]

Should be live now !

[sgitkene]

seems to work now 🥳
