Mandate and decision-rights mapping
Laws, budgets and organisational charts are read to map which body decides, funds, implements and reviews each climate or nature responsibility, and where mandates overlap or are missing.

Policy, institutional and decision science for climate and nature governance
Policy and institutional science studies how mandates, laws, budgets and review bodies shape what governments and organisations do. On this platform it compares climate and nature institutions across countries, traces how commitments become delivery, and maps who holds each decision.

02Application
What policy, institutional and decision science does here.
Policy, institutional and decision science studies how public decisions are made, implemented and evaluated. It examines how institutions coordinate across sectors and levels of government when facing shared risks. In climate and hazards, biodiversity and nature, water and food and agriculture, policy science identifies governance gaps where responsibility for cross-sector risk is unclear. It supports the design of mandates, coordination mechanisms and accountability. The canonical description is on the STEM Commons.
Process tracing of commitments
A target is followed through plans, budgets, permits and outcomes, using public records to identify where it stalled and why.
Comparative institutional analysis
Climate framework laws, basin agreements or disclosure regimes are compared across countries with their context stated, so lessons are not transferred without conditions.

05Policy scenarios
Compare instruments: rules, incentives and information.
Three families of instruments side by side against the baseline, each with its own lag and adoption speed, under the coverage and compliance you set; effect sizes are teaching values to replace with evidence. Scenario: named assumptions about the future, not a forecast.

06Validation
How results are checked.
Conclusions are tested through comparative cases, counterfactual evaluation and peer review. Implementation outcomes are monitored against stated objectives.
| Check | How it is done |
|---|---|
| Case selection stated | Comparisons state why cases were chosen and what they cannot represent |
| Triangulation | Claims about institutional behaviour are checked against several independent records |
| Context conditions | Lessons are stated with the conditions under which they held |
Findings are often context specific and difficult to transfer. Political dynamics can override technically preferred options.
07Implementation
From mandate to evaluation, by pillar.
The steps an instrument takes from mandate to evaluation, each with the pillar that runs it, and the decisions that stay with the authority. Teaching model with stated illustrative values, not a prediction.
- Mandate and problem framing Competent authority (outside the programme)
A competent authority frames the problem and the mandate under its own rules. Howlett, Ramesh and Perl (2009) - Evidence and system model Foundry
The system is modelled with its feedbacks, data and stated limits. OECD (2014), principle 2 - Options appraised with scenarios Foundry
Instruments are compared under scenarios, with uncertainty shown. Hood (1983) - Exercise with stakeholders Universe
The options are tested in an exercise with those who would implement and bear them. OECD (2014), principle 3 - Standard or guidance drafted Nexus Standards
What works is codified as a standard or guidance, open to comment. Nexus Standards process - Decision by the authority Competent authority (outside the programme)
The authority decides, outside the programme, with the evidence on record. Howlett, Ramesh and Perl (2009) - Capacity and training Risk Academy
Those who implement are trained on the decided instrument and its data. Sendai Framework (2015), priority 2 - Monitoring and public report Reports
Indicators are published with sources, limits and corrections. OECD (2014), principle 5 - Evaluation and revision Nexus Standards
Results return to the standard and the model: the cycle closes. Howlett, Ramesh and Perl (2009)
