Waste management policy to enhance climate change mitigation

Project description

Title: Support to the implementation of the National Policy for Solid Waste considering climate-protection (ProteGEEr)
Commissioned by: Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU)
Country: Brazil
Lead executing agency: Ministry of Cities (Ministério das Cidades, MCidades) and Ministry of the Environment (Ministério do Meio Ambiente, MMA)
Overall term: 2017 to 2021

In 2010 Brazil adopted a forward-looking waste management policy, which has, however, only been partially implemented. Greenhouse gas (GHG) emissions in Brazil continue to rise, even in the waste sector. Specific CO2 reduction targets in the waste sector have yet to be mainstreamed in either the National Plan on Climate Change or Nationally Determined Contributions (NDCs).

Despite increasing pressure from environmental protection agencies, municipalities are reluctant to implement waste management measures. The reason for this is a lack of project examples as references, as well as insufficient information and implementation experts. Little advantage has been taken of subsidised loans available, for instance, through the state-run bank, CAIXA.

A new version of the national solid waste management plan is likely to be adopted in 2018. This would create opportunities to align it with the National Plan on Climate Change and make use of the waste sector’s potential for climate change mitigation.


The Brazilian waste sector provides a tangible contribution to targets for the reduction of GHG emissions and consequently to climate change mitigation. Brazil’s waste management policy brings together both short-term objectives, such as efficient waste treatment options, and long-term objectives, such as climate change mitigation, and plays a leading role in Latin America.

The project advises ministries at national level on integrating climate-related criteria, (emission reduction potential), into rules and regulations for the waste sector. To achieve this, methods of calculating GHG emissions from municipal solid waste are being reviewed and amended to reflect the Brazilian context. Technologies to minimise GHG emissions will be supported and recycling promoted. 

At municipal level, those in local government and private sector employment are trained in planning and implementing effective and climate-friendly waste management. The project promotes the use of new decision-making tools in 10 selected cities and municipalities to train local authorities and businesses in the selection of technologies and methods.

In collaboration with five universities, the project develops curricula for postgraduate studies on sustainable waste management and climate change mitigation. The project also supports research projects and dialogue between German and Brazilian research institutions.


A waste laboratory is being created. For this purpose, a cooperation agreement was signed with NUTEC (Fundação Núcleo de Tecnologia Industrial do Ceará), a state research institute in the Brazilian state of Ceará. 

The project supported five national universities with applying for PRINT funds, which provides them with access to additional money that indirectly benefits climate change mitigation.

GIZ and its partners developed lecture and training units relating to climate-change mitigation subjects from the waste sector.

Initial results from the interministerial working group on data systematisation are available: the databases of the city ministry should be adapted so that they can be utilised as an official database for calculating Brazil’s emission statistics (greenhouse gas inventory). (as at: October 2018)
