Sustainable Investment Management

A boutique environmental finance firm based in the UK and Brazil

Sustainable Investment Management Ltd (SIM) is an environmental finance advisory firm.

Our objective is to promote the financing of activities that result in positive environmental impacts worldwide.

SIM coordinates the blending and integration of sources of finance, services and activities related to its investments.

SIM uses a combination of:

  • Sophisticated financial mechanisms.
  • Advanced technology tools (including remote sensing and blockchain technology).
  • An experienced team of experts and associates in environmental finance, carbon trading, commercial law, and environmental sciences.


At SIM, we have witnessed first hand the immense potential of combining private and public capital toward achieving targeted environmental goals. We also know from experience that pursuing “green” investments and seeking attractive financial returns are not mutually exclusive.

Our vision is to create a double bottom-line global investment firm to mobilize capital for actionable sustainable development. We do this by connecting investors seeking positive environmental change with credible businesses and implementable projects that have a direct and immediate environmental impact.

Our aim is that our financial mechanisms can have a disruptive effect at scale, helping to inflict change at sector or landscape level.

SIM is engaging with businesses and projects across various sectors, as follows:

Sustainable Agriculture

Promote farming practices and methods that are profitable, environmentally sound and good for communities, (such as zero deforestation and recycling of crop waste and livestock).

SIM has designed and is managing the Responsible Commodities Facility, a programme to provide financial incentives to soy farmers committed to zero deforestation in Brazil.

Sustainable Forest and Conservation Finance

Provide finance to support sustainable forestry practices and forest conservation, reducing greenhouse gas emissions and loss of biodiversity.

SIM has designed and is managing the SIMFlor programme, to provide financial incentives for landowners to comply with the Brazilian Forest Code.

Greenhouse Gases (GHG)

Reduce the emissions of GHGs, help offset carbon footprints and accelerate the transition to a low-carbon economy.

To promote this agenda, SIM acquired a significant stake in ecosecurities, a market leader in carbon markets.

Waste Management and the Circular Economy

Promote the use of proper and sustainable solid waste management solutions, including the plastics recycling.

To promote this agenda, SIM has developed Circular Action BV, a new venture dedicated to developing circular economy solutions in developing countries.

We also work in partnership with BVRio, a not-for-profit organisation designing and promoting innovative market-based solutions for the green economy, which has a presence in Brazil, UK, the Netherlands, Indonesia and China.
