Recycling plastic waste has powerful climate impacts that need to be quantified

Plastic waste pollution contributes to climate change while improved waste management and recycling can help mitigate climate impacts. However, decision-makers lack the relevant tools and accessible information to help them assess the opportunity for investing in the waste management and recycling value chain.


The Circulate Initiative has developed an open-sourced prototype GHG calculator to track the environmental impact of plastic waste management and recycling solutions that prevent plastic pollution in India and Indonesia. This tool is based on the findings of a paper published by Circulate Capital and the Singapore Institute of Manufacturing Technology (SIMTech), a unit of Singapore’s  Agency for Science, Technology and Research (A*STAR).


The resulting tool allows users to assess the extent to which their investments can generate quantifiable climate benefits, specific to the unique characteristics of Asian waste management systems.

About the calculator

About the Calculator

Use PLACES to generate custom queries and calculate carbon savings for India and Indonesia based on:

  • Plastic-type

  • Tonnes of plastic waste

  • End-of-life fates

For example, what are the climate impacts of diverting 25,000 tonnes of plastic from incineration? What if it's high-density polyethylene?

Our inspiration for PLACES

PLACES is inspired by the US Environmental Protection Agency’s Waste Reduction Model (WARM), which assists organizations and individuals in tracking and reporting greenhouse gas emissions reductions and economic impacts based on US waste recovery models. 


PLACES was launched to provide investors data for India and Indonesia; two markets that are at different stages of recycled plastics market development and waste management infrastructure. India and Indonesia also represent two major markets in South and Southeast Asia  where plastic waste contributions are significant today and forecast to grow in the coming decades due to the growth in consumer class and higher urbanization rates of medium sized cities.

How the Tool Can Help You

Are you ...


An Investor

ESG-focused investors can use the calculator to evaluate supply chain interventions to mitigate climate risks and strengthen the transition to a low-carbon economy.


An Entrepreneur

Recyclers and service providers can use the calculator to estimate their contribution to greenhouse gas, energy, and water savings.


A City Planner

Waste management and urban resilience planning teams can quantify and compare the impacts of recycling interventions and strategic scenarios.

From Our Partners

"The recent International Panel on Climate Change’s report is another wake up call to take immediate action against climate change and reducing plastic waste should be part of the plan since the climate and the plastic crisis are intertwined. The Circulate Initiative’s work to assess the intersection of climate investing and circular plastics in SSEA is the first of its kind to demonstrate the potential for the circular economy to reduce greenhouse gas emissions and support climate action.

Their work is also valuable as it illustrates tangible ways investors and other actors can support the Marrakech Partnership for Global Climate Action Pathway for Plastics and accelerate the Net Zero transition. Accounting only for the tip of the iceberg, proper waste management and recycling prove to be effective tools to deliver impacts as high as the reduction of 148 million tCO2e by 2030, combining India and Indonesia’s scenarios.

I hope that TCI's online calculator will shine a new light for decision makers quantifying impacts of climate."
