Documentation for CO2 removal technologies in MESSAGE

[ywpratama]

This draft PR includes a proposal for the documentation of CO2 removal technologies in MESSAGE

How to review

When reviewing this draft PR, please provide feedback on the following but not limited to:

• Parent location of the doc. At the moment, it is put under emissions, but Energy section might be an option too.
• Now CDR technologies has its own section within the Emissions page. Please suggest whether this is appropriate or should it be moved under CO Emissions section
• This doc is planned to include other novel CDR technologies beyond those that are already included in the scenario MIP scenarios setup, so not only BECCS and DACCS. Please comment if this is OK or should we just put BECCS and DACCS for this.

PR checklist

• Continuous integration checks all ✅

Thanks, @ywpratama. My main suggestion is to move the section one level up, so that it appears directly under the "Emissions" section.

[volker-krey]

I would suggest to add the "CO2 Removal Technologies" section, one level higher, i.e. directly below the "Emissions" heading in doc/global/emissions. This would be consistent with the structure of the IAMC Wiki.

[ywpratama]

Thanks, Volker. As suggested, I just moved the section up one level. So, the CDR section is directly under emissions, together with Emission from energy (MESSAGE) and Emissions from land (GLOBIOM) sections.

[volker-krey]

Adding conventional CDR, so afforestation and reforestation, would be important so that the list is comprehensive.

[ywpratama]

I just added the placeholder for conventional CDR on land on the CDR methods section for now. Will need to coordinate with GLOBIOM team (Yazhen?) and Oliver for the documentation
