Paris Budget Burn-Down API

A live dashboard that shows how much of the global carbon budget is left before the world hits specific warming limits.

An embeddable API and dashboard module that converts the annual Global Carbon Budget into a live 'remaining carbon budget' ledger — cumulative emissions, current run-rate, and projected exhaustion dates for 1.5°C and 2°C — so ESG platforms can show corporate net-zero targets against the actual global budget they depend on.

Concept

A data product that takes each year's Global Carbon Budget release (openly published, methodologically consistent back to 1959) and computes: cumulative anthropogenic emissions since the pre-industrial baseline, the current global run-rate, the implied remaining budget for 1.5°C and 2°C, and a projected exhaustion date with uncertainty bands. It is sold as a white-label module to carbon accounting and ESG platforms, so their corporate customers see their own reduction targets contextualized against the global budget that science-based targets are derived from. Single wedge: every net-zero target implicitly assumes a remaining global carbon budget, but no corporate tool surfaces that budget's actual burn rate; this module makes it a live, annually refreshed number inside existing dashboards rather than a static footnote in a PDF.

Why now

The 2025 edition provides the freshest, consistently-methodologized inputs: 2024 total anthropogenic emissions of 42.4 ± 3.2 GtCO2/yr, fossil emissions still growing (+1.1% in 2024 and a preliminary +1.1% for 2025), and atmospheric CO2 at 422.8 ± 0.1 ppm in 2024 heading to a preliminary 425.7 ppm in 2025 — 52% above the pre-industrial ~278 ppm. With global emissions not yet peaked, the burn-down rate is moving in the wrong direction, which is precisely the context corporate target-setters are asked to respond to but never see quantified in their own tools. The dataset's annual cadence, open availability (doi 10.18160/GCP-2025), and consistent 1959–2024 methodology make a maintained derived service cheap to build and defensible to audit.

A focused data-as-a-service play that turns a complex annual scientific report into a live API for ESG platforms, though it faces a high risk of being a 'feature' rather than a standalone business.

Evidence strength
5/5
The idea relies directly on the Global Carbon Budget 2025, which provides the exact, high-precision metrics (GtC, ppm, and growth rates) required to calculate the burn-down.
Market pull
3/5
While ESG platforms (Watershed, MSCI) have the budget, the urgency to show a 'global countdown' is a secondary UX improvement rather than a primary pain point for corporate compliance.
Novelty & moat
3/5
It is distinct from the 'Carbon Cycle Anomaly Watch' by focusing on the budget exhaustion date for corporate targets rather than risk alerts for insurers.
Feasibility
5/5
The data is open and methodologically consistent; building a wrapper API and a dashboard module is a low-complexity engineering task.
Wedge clarity
4/5
The wedge is sharp: providing the 'missing context' for net-zero targets within existing carbon accounting dashboards.
Simplicity / focus
5/5
The product is a single, well-defined API and module without unnecessary feature creep or platform bloat.

Who benefits

  • Science Based Targets initiative (SBTi)organization

    Validates corporate net-zero targets against remaining carbon budgets; an annually updated, uncertainty-banded burn-down feed gives its target-setting guidance a transparent, current global reference.

  • Carbon Tracker Initiativeorganization

    Analyzes the gap between fossil fuel capital expenditure and carbon budgets; a live burn-down API directly supports its carbon-bubble research and investor communications.

  • MSCIcompany

    Runs net-zero and climate target-tracking products for investors; embedding the global budget burn-down differentiates its target-credibility scoring.

  • Watershedcompany

    Corporate carbon accounting platform whose customers set net-zero targets; a budget-context module answers 'how fast does the world actually need to move' inside the same dashboard.
