Goal workspace
Route one bounded energy/transport calculation or build a source-led efficiency or solar decision dossier with current tariffs, site evidence, qualified authorization, and measured follow-up.
Explore Environment, Land & SustainabilityDecision brief
A dated sustainability decision record with named owner, source-linked baseline and assumptions, comparable options, qualified authorization, accessible handoff, measured results, and an explicit acceptance trail.
You need one bounded arithmetic record for entered energy, transport, emissions, nameplate, tilt-heuristic, cash-payback, or return assumptions and understand what the tool omits.
Bills/tariffs, site evidence, models, options, quotes/contracts, incentives, permits/interconnection, qualified work, commissioning, monitoring, accessibility, and acceptance must stay coordinated.
Choose your path
Route a household to one bounded energy/transport/carbon arithmetic record or a source-led multi-step efficiency/solar Project while preserving current authorities, qualified work, accessibility and measured acceptance.
Use the smallest honest calculator without turning it into a product or policy recommendation.
Choose the relevant quick Tool, retain its assumptions and follow its authority/Project handoff when the decision expands.
Gets reproducible arithmetic and visible omissions rather than a proprietary green score.
Connect tariff, site, quote, contract, permit and commissioning evidence.
Enter Save on Energy or Go Solar and complete the named evidence/authorization gates.
Qualified reviewers and the named owner—not the Goal hub—authorize the work.
Keep multiple outcomes and affected people visible.
Define acceptance, compare feasible options on one basis, document accessibility/resilience needs, and measure actual results.
Can explain tradeoffs and the next review without claiming one universal best green action.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
