List all 10 Northwood portfolio companies with sector, status, and headline metrics.

Returns a list of dicts containing: slug, name, sector, fund, status, revenue ($M), ebitda ($M), facilities count, data_grade, base_year, target_year, target_reduction_pct.

Use this as the starting point for portfolio-level questions.

Get Scope 1 and Scope 2 emissions for a specific portfolio company.

Args: portco: Portco slug (e.g. 'meridian') or name substring (e.g. 'Meridian'). year: Optional. Restrict to a single year (e.g. 2024). If omitted, returns totals for every available year. scope: Optional. 1 or 2 to filter to a single scope. If omitted, returns both.

Returns: Dict with portco metadata and an 'emissions' map of {year: {scope1, scope2, total}} in tCO2e. Values are tonnes CO2-equivalent.

Compute gap between current trajectory and SBTi-aligned reduction target.

Uses latest forecasted annual total and compares against the pro-rated linear pathway from base year to target year.

Args: portco: Portco slug or name. target_year: Year to evaluate against (default 2030).

Returns: Dict with: current_tco2e, target_tco2e, gap_tco2e, gap_pct, on_track (bool), verdict (short string).

List decarbonization initiatives with estimated reduction, capex, and payback.

Args: portco: Optional. Filter to a single portco. If omitted, returns all portfolio initiatives. status: Optional. One of 'planned', 'in_progress', 'complete'.

Returns: List of initiative dicts: {portco, id, name, category, status, est_reduction_tco2e, capex_k, start_date}.

Useful for cost-curve analysis, payback screening, and status roll-ups.

What-if analysis: apply a subset of initiatives and return projected post-lever emissions.

Args: portco: Portco slug or name. initiative_ids: List of initiative IDs (from list_initiatives) to 'turn on'.

Returns: Dict with baseline (current trajectory endpoint), applied initiatives, total reduction, total capex, and new endpoint vs target.
