A.1Research question formulation
Excellent
A.2Environmental issue context
Excellent
A.3Connection between issue and research
Excellent
Criteria Feedback
- Clear, specific and focused research question with defined scope, variables and timeframe
- Rich environmental context linking fossil-fuel dominance, policy differences and renewable adoption
- Comprehensive explanation of how emissions–GDP relationships are moderated by renewables
- Minor punctuation and wording issues in the research question
- Background lacks quantitative global emission figures to deepen context
- Hypothesis could more explicitly reference the moderating role of renewable energy
1.1·Strength
Page 1
The research question is clearly specific, manageable, and defines geographic scope, variables, and timeframe, demonstrating coherence and focus.
1.2·Suggestion
Page 1
The environmental issue context is introduced but could be enriched with quantitative global emission figures to strengthen the background.
1.3·Strength
Page 2
The student provides a clear description of fossil-fuel combustion chemistry and variations by fuel type, demonstrating strong subject knowledge.
1.4·Strength
Page 2
The regional context linking Northern European renewable strategies to decoupling emissions from growth effectively supports the study’s focus.
1.5·Suggestion
Page 2
This summary links variables and purpose but would benefit from explicitly restating the research question to reinforce coherence.
1.6·Weakness
Page 3
The hypothesis focuses on Northern Europe but should explicitly reference the moderating role of renewable energy across all five countries.

B.1Method design
Excellent
B.2Sampling strategy
Moderate
B.3Risk and ethical considerations
Excellent
Criteria Feedback
- Method design is detailed, repeatable and appropriate for collecting the required secondary data
- Variables are clearly defined with reliable data sources and timeframes
- Risk and ethical considerations are comprehensively addressed for a secondary-data study
- Sampling strategy lacks justification for the chosen 10-year period and sample size
- Statistical significance testing is not incorporated into the method design
2.1·Suggestion
Page 4
Include statistical significance testing in the method design to fully address patterns in the data.
2.2·Strength
Page 4
Variables are clearly defined with credible data sources and timeframes, providing a solid foundation for replication.
2.3·Weakness
Page 5
The sampling strategy lists per capita data collection but lacks justification for the chosen 10-year period, which could affect data comprehensiveness.
2.4·Strength
Page 5
The methodology description is detailed, citing reliable data sources and a secondary research approach that ensures consistency.
2.5·Strength
Page 6
The risk and ethical considerations are thoroughly addressed, covering data usage, citation, and environmental impact assessment.

C.3Conclusion drawing

Criteria Feedback
- Graphs and tables present key GDP, emissions and energy-mix data clearly for most countries
- Pearson correlation coefficients are calculated correctly and interpreted appropriately
- Conclusions on decoupling patterns are reasoned and supported by the data provided
- Formatting and labeling errors (comma separators, missing units, incomplete Germany table)
- Analysis omits significance tests, confidence intervals and scatter plots
- Some tables contain typographical and decimal-separator inconsistencies
3.1·Weakness
Page 7
There is a formatting error in Germany’s GDP value '43.855.9'; please correct to maintain data accuracy.
3.2·Suggestion
Page 7
Add unit labels (e.g., USD per capita, million tonnes) directly to the table headers to improve clarity.
3.3·Weakness
Page 8
In Table 3, spelling errors ('concption') and inconsistent decimal separators may confuse readers; revise formatting.
3.4·Strength
Page 10
The representation of Denmark’s energy mix data in Table 5 is clear and facilitates comparison across years.
3.5·Suggestion
Page 13
The y-axis of Figure 1 lacks units; include 'USD per capita' to clarify the scale.
3.6·Strength
Page 14
Figure 2 effectively visualizes emissions trends per capita, supporting the identification of decoupling patterns.
3.7·Weakness
Page 21
The statement infers significance without p-values or confidence intervals; include statistical tests to support claims.
3.8·Suggestion
Page 22
Consider reporting actual R² values alongside interpretations to quantify variance explained by GDP growth.
3.9·Strength
Page 22
The analysis section offers clear, country-specific interpretations linking R and R² values to policy and industrial factors.

Criteria Feedback
- Discussion links findings to broader environmental context using IEA research
- Explicit description of methodological strengths, weaknesses and limitations
- Meaningful suggestions for sample extension and further policy/technology research
- Depth of evaluation is uneven and lacks quantitative support
- Does not sufficiently reflect on earlier methodological limitations
4.1·Suggestion
Page 9
Consider adding a brief interpretation of nuclear share trends to highlight their relevance in the energy mix discussion.
4.2·Strength
Page 23
The discussion integrates IEA research to contextualize findings, demonstrating solid connection to external sources.
4.3·Weakness
Page 24
The evaluation correctly notes systemic factors but omits reflection on earlier methodological limitations.

Good
Criteria Feedback
- Proposes large-scale renewable adoption solution linked to emission reduction
- Discusses relevant strengths and weaknesses of renewables (e.g., cost, intermittency)
- Justification is loosely connected to the study’s quantified findings
- Does not evaluate all relevant trade-offs (e.g., land use, grid stability)
5.1·Weakness
Page 24
The application proposal describes renewables broadly but lacks direct linkage to the study’s quantified findings for justification.
5.2·Strength
