THE PLACE BEHIND THE OPPORTUNITY

Our editorial thesis: practical impact opportunities lie in coordinating existing institutions and informal-to-formal economic activity. Define a municipal territory and buyer; prove reliability and income benefits before scaling.

São Paulo's current PlanClima portal distinguishes a municipal 2030 emissions reduction of 20% against 2017 from a 50% ambition requiring joint action with other city sectors. It seeks net-zero municipal-territory emissions by 2050. Those are different commitments, not interchangeable claims. Its summary of average 2010–2022 emissions assigns 60% to transport, 31% to stationary energy, and 9% to waste. Historical shares inform discovery, not present-day valuations.

01 / THE EVIDENCE, DRAWN TO SCALE

One place. A wider context.

São Paulo context sits beside the global signal. Different geographies and units remain separate.

2023 is the reported baseline. 2050 is a projection under UNEP's described trajectory, not an observed result or a revenue forecast.

THE BUYER QUESTION

Cooperatives, commercial waste generators, and buyers with clear material specifications; confirm concession and collection boundaries before changing routes.

THE EXPERIMENT

Co-design a traceable batch workflow with one willing cooperative and one verified materials buyer.

Increase the value of material recovered by cooperatives. The City's selective-collection page describes accredited cooperatives and the flow of recyclable materials through the municipal system.

RESEARCH HYPOTHESIS · TO VALIDATE LOCALLY

The opportunity

Test cooperative-owned weighing, quality records, scheduling, and buyer coordination. The commercial goal should include more value reaching workers, not only more material captured by a platform.

03 / PROPOSED IMPACT FRAMEWORK

Make the benefit testable.

An impact claim should survive a difficult question. Design the measurement before you design the success story.

  1. 01

    Establish the baseline

    Start in São Paulo. Define the people, geography and existing service before measuring a change.

  2. 02

    Run a bounded pilot

    Use the proposed experiment above as a starting question. Agree the local scope, duration, comparison and safeguards before beginning.

  3. 03

    Compare the outcome

    Ask what would have happened otherwise. Compare like with like and record how much uncertainty remains.

WHAT TO MEASURE

The outcome ledger

  • LOCAL OUTCOME MEASURE

    Saleable yield, contamination, price per kilogram, payment delay, worker net income, and safety incidents.

Keep the counter-evidence.

Keep workers in control of their data and commercial terms; do not divert valuable materials away from existing cooperative livelihoods.

Proposed measurement pathway. No baseline, pilot result, participant count or achieved impact is being reported in this diagram.

PUT IT IN PERSPECTIVE

The global market context.

UNEP’s 2024 waste outlook projects municipal solid waste increasing from 2.1 billion tonnes in 2023 to 3.8 billion tonnes in 2050 under the described trajectory. The 2050 figure is a projection, not measured waste or a revenue forecast.UNEP / International Solid Waste Association

UNEP and the International Resource Panel report that natural-resource extraction tripled over the previous five decades. Material consumption, infrastructure and environmental impacts must be considered together; recycling alone cannot establish circularity.UNEP / International Resource Panel

WHAT TO LEARN BEFORE BUILDING
  1. Can the need for a new product or material be avoided first?
  2. Who will buy the recovered output at a repeatable quality?
  3. Does the model improve conditions for existing workers?

Follow the evidence.
