What’s new on the platform

To learn which pages are used and for how long, the platform counts visits anonymously: no cookie, no identifier and no IP address. Only daily totals are kept.

The Privacy Policy describes the anonymous count, and the cookie notice appears once more so you can confirm your choice under the updated text.

The About menu leads to the CP2b pages, kept by the centre itself: about CP2b, governance, partners, research axes, solutions, team, publications, news, events and contact. The old PILAR-2b About page redirects there.

The platform's frequently asked questions are now at the end of the Guide, and data error reports go through the CP2b contact form.

The map opens on the Map basemap (OpenStreetMap) again. The Light canvas option is gone: its provider started requiring a key and covered the map with an API KEY REQUIRED notice.

In the map panel, the Data Sources tab is now called Sources.

A new look: terracotta colours, serif headings and a light theme by default. The footer was refreshed too.

Each municipality's page is now a dashboard: highlights at the top, the split by sector and by residue as bars and its place among its neighbours, all much shorter.

On the map, clicking a municipality opens a side panel with the total, levels N4 and N3, the main residue and the residues by sector, in methane or in tonnes.

The IBGE link in the map panel now works for names with accents too.

Next.js updated to 16.4.0, closing critical flaws, among them one in the share-image generator.

Each municipality has its own page at /municipalities/name-state (for example, /municipalities/campinas-sp): the accessible methane potential (level N4), its rank in the state, the split by sector and by residue, the method's levels, the neighbouring municipalities, how to cite it and the notes and limitations.

When the page is shared on WhatsApp, LinkedIn or other networks, the link shows an image with the municipality's name and its methane potential.

The old addresses (/municipality/IBGE code) lead automatically to the new page. The municipality search and list include every municipality covered.

The home page introduces the platform and leads straight to the map and the data catalogue. The map stays at /map.

Data catalogue: one page per sector and per residue, with the methane potential (BMP), the chemical characterization, the sources and how to cite, plus the layer legend and codes to download as CSV.

Menus regrouped into Platform, Data, Method and About, each with a short introduction. On phones, a bottom bar leads to the Map, the Municipalities, the Data and the full menu.

An alphabetical list of every municipality, with search, at /municipalities.

The multi-criteria analysis, the calculator and the science base mark the figures computed with the previous availability factors as "previous estimate (legacy)"; they stay in use until the new estimate is published.

Old addresses that moved now redirect to their new place instead of showing a page-not-found.

The CP2b method v5.1 comes to the platform for São Paulo's 645 municipalities: four potential levels (theoretical, technical, mobilisable and accessible) per substrate and scenario, in Nm³ of methane, computed through one factor cascade. Statewide, the mobilisable level (N3) is 19.2 Mm³/day of CH₄ and the accessible level (N4), which applies storage losses and the logistic factor computed on the road network, is 16.4 Mm³/day. The minimum and maximum scenarios (7.7–45.0 and 5.2–42.7) are an envelope, not a probability interval.

The Real and Ideal scenarios now follow the CP2b method: Real is the accessible potential (N4, 16.4 Mm³/day of CH₄) and Ideal the mobilisable one (N3, 19.2). They used to come from the Atlas de Bioenergia SP 2020 (21.5 and 27.0 Mm³/day). The difference is a change of method and of residue coverage, not a revision of the same figures. The map, the totals strip, the municipality page and the XLSX dossier change together. CP2b sugarcane includes the surplus bagasse, and the method has no aquaculture or forestry, which now show as no data.

API: /api/v1/cp2b/summary (state totals), /api/v1/cp2b/municipalities/{ibge} (levels per substrate, with the logistic factor) and /api/v1/cp2b/parameters (calculation elements with source and status). Eleven of the 17 substrates still carry provisional parameters, and the API says so next to the numbers.

The C:N ratio for São Paulo's 645 municipalities now uses the N-additive balance — ΣVS / Σ(VS/CN) — instead of the arithmetic mean. Nitrogen is additive, so the arithmetic mean does not describe a mixture: it misclassified 44% of municipalities. Municipalities in the ideal 20–30 band rise from 111 to 191.

The C:N profile and nutrient regime map layers are back, now on the corrected data. They cover São Paulo only; outside the state the value was never computed, and the map leaves those areas blank rather than drawing zero.

New exportable municipal dossier: a pt-BR workbook with per-residue, infrastructure and sources tabs, plus a PDF report with a vector locator map.

Next.js upgraded from 16.3.2 to 16.3.5, closing two critical remote-code-execution flaws (GHSA-p293-qw3h-jr36 and GHSA-2xp9-vwfh-vxw4). Neither reached the published site — the exposure was the development environment.

The Guide, About and How to Cite pages are now fully translated, with two automated checks that stop new text from reaching the English site still in Portuguese.
