            - **Target**: Targets are an intention to achieve a specific result, \
            for example, to reduce GHG emissions to a specific level \
            (a GHG target) or increase energy efficiency or renewable \
            energy to a specific level (a non-GHG target), typically by \ 
            a certain date.
            - **Economy-wide Target**: Certain Target are applicable \
                not at specific Sector level but are applicable at economic \
                wide scale.
            - **Netzero**: Identifies if its Netzero Target or not.
                - 'NET-ZERO': target_labels = ['T_Netzero','T_Netzero_C']
                - 'Non Netzero Target': target_labels_neg = ['T_Economy_C',
                  'T_Economy_Unc','T_Adaptation_C','T_Adaptation_Unc','T_Transport_C',
                  'T_Transport_O_C','T_Transport_O_Unc','T_Transport_Unc']
                - 'Others': Other Targets beside covered above
            - **GHG Target**: GHG targets refer to contributions framed as targeted \
                              outcomes in GHG terms.
                - 'GHG': target_labels_ghg_yes = ['T_Transport_Unc','T_Transport_C']
                - 'NON GHG TRANSPORT TARGET': target_labels_ghg_no = ['T_Adaptation_Unc',\
                   'T_Adaptation_C', 'T_Transport_O_Unc', 'T_Transport_O_C']
                - 'OTHERS': Other Targets beside covered above.
            - **Conditionality**: An “unconditional contribution” is what countries \
             could implement without any conditions and based on their own \
             resources and capabilities. A “conditional contribution” is one \
             that countries would undertake if international means of support \
             are provided, or other conditions are met.
            - **Action**: Actions are an intention to implement specific means of \
             achieving GHG reductions, usually in forms of concrete projects.
            - **Policies and Plans**: Policies are domestic planning documents \
              such as policies, regulations or guidlines, and Plans  are broader \
             than specific policies or actions, such as a general intention \ 
             to ‘improve efficiency’, ‘develop renewable energy’, etc. \
            The terms come from the World Bank's NDC platform and WRI's publication.
