Same lens, different regimes
- The method travels. Both pages score the same way: sum a trailing-12-month window per reporting unit, group it with peers of the same kind and size, and rank within the peer group. A unit is an outlier only when it is both extreme (≥95th percentile) and material.
- The reporting units differ. Alberta reports against facilities (batteries, gas plants); Texas reports against leases. Both are the operator’s unit above the well — the lens doesn’t care.
- The windows differ wildly. Texas publishes monthly data back to 1993; Alberta’s public archive is a rolling ~5 years. Depth vs freshness is itself a policy choice.
- So does transparency. Alberta publishes vented and flared volumes separately for every facility. Texas operators have reported the split since 2021 — but every bulk product the RRC publishes folds it back into one “vented or flared” number.
- Absolute comparisons are apples-to-oranges. Different rules, different measurement, and both jurisdictions are known to under-report against satellite observation. What compares honestly is the shape: outlier structure, peer distributions, and trends — which is what these pages show.
