As a CIIP user (reporter and analyst), I want the AR5 GWP values to be in effect, so that I have accurate CO2e calculations for my emissions

[pbastia]

Description:

BC is using now AR5 GWP values (https://www2.gov.bc.ca/assets/gov/environment/climate-change/ind/reporting-emissions/2023/ggrica_bulletin_025.pdf)

Acceptance Criteria:

Given I am an industrial reporter When I fill out my application for 2022 reporting year And I am on the emissions tab Then I see AR5 GWP values And the calculations reflect that

Given I am a CIIP analyst When I view 2022 reporting year applications Then I see AR5 GWP values And the calculations reflect that

Given I am a CIIP analyst When I view applications before 2022 (2021 and before) Then I see AR4 GWP values

Dev checklist

• [ ] ciip gas table now needs temporal column (reporting_year_start, reporting_year_end) and description
• [ ] new data for AR5 GWP values in the gas prod data
• [ ] Anywhere using that table now needs to fetch the correct gas data depending on the application reporting year
• [ ] Tests for the logic where we select the proper gas

Hey team! Please add your planning poker estimate with Zenhub @dleard @Sepehr-Sobhani @BCerki @JoshLarouche @gurjmatharu @sam-warren

What calculations needs to change as part of this?

[pbastia]

@BCerki In the application process, both reporters and analysts see a conversion of emissions to tCO2e (tonnes of CO2 equivalent) - the GWP (global warming potential) are numbers for each gas that compare it with CO2. So CO2 has a GWP of 1, and all the other gasses a factor of that.

Thank you @dleard !
