◻️ Other (please give a description)

Impact

◻️ Bug fix
◻️ Refactoring
◻️ New feature
◻️ Change of parameter values or input data (including CES parameters)

In the end all checkboxes must be ticked before you can merge.

I executed the automated model tests (make test) after my final commit and all tests pass (FAIL 0)
I adjusted the reporting in remind2 if and where it was needed
I adjusted the madrat packages (mrremind and other packages involved) for input data generation if and where it was needed
My code follows the coding etiquette
I explained my changes within the PR, particularly in hard-to-understand areas
I checked that the in-code documentation is up-to-date
I adjusted forbiddenColumnNames in readCheckScenarioConfig.R in case the PR leads to deprecated switches
I updated the CHANGELOG.md correctly (added, changed, fixed, removed, input data/calibration)

This does not have the same EDGE-T scenario as NPI2025 and still the old description. It should just be a copy of NPi2025 with calibration on, right?

will adjsut it

The NPi assumes that policies fail to achieve NDC targets in 2030. Instead, carbon prices are assumed to grow and converge more slowly, leading to emissions trajectories in line with bottom-up studies on the effect of currently implemented policies.


Didn't we want to keep the NPi and rename it to NPi2020? That was my understanding from the issue.

I was not sure as what would be the meaning of a scneario calibrated to NPi2025 and run with NPi?

Well, I share your view that it is quite a different scenario than the NPi before and it is not really needed anymore But, my understanding from the issue was we want to keep at least it a few more weeks for comparisons.

added this scenario again

I would prefer having the order of

NPi2025-calibrate Npi2025 Rollback Npi2020 NDC PkBudg1000 PkBudg 750

So it is (mostly) increasing in ambition.

I prefer not to change the order to not confuse people who use other sconfig files

change default calibration scenarios from NPi to NPi2025
