Chemical Leasing


In 2004, with the support of the Government of Austria, UNIDO launched its Global Chemical Leasing Programme, promoting a business model that marks a paradigm shift from increasing the sales volume of chemicals toward a value-added approach.

The conventional business model assumes that the more you sell, the more you earn. However, in the Chemical Leasing model the supplier does not sell quantities. The supplier sells the function of the chemical. This is the service rendered by the chemical or the purpose for which the chemical is applied.

For example, the function of the chemical could be to clean or degrease metal parts, or to protect a surface. Payment is then made according to functional units, that is, the number of pieces cleaned or the extent of area coated.

In 2018, more than ten years later, there is no doubt that Chemical Leasing can build the business case for Sustainable Chemistry by creating win-win situations for business partners and the environment.

Built on strong cooperation between partners and based on mutual trust, it increases the efficient use of chemicals, reduces the risks to human health brought about by their use, improves the economic and environmental performance of participating companies and ultimately enhances business performance.


On 21 November 2016, the UNIDO-led global and multi-stakeholder initiative on Chemical Leasing achieved another milestone with the signing of the Joint Declaration of Intent on Chemical Leasing between UNIDO, Austria, Germany and Switzerland under the umbrella of UNIDO's 50 Years' anniversary week in Vienna, Austria. The legally non-binding declaration is open for additional partners and aims to increase awareness of chemical leasing at the political level and strengthens the cooperation of the partners in global promotion activities.

UNIDO's Global Chemical Leasing Programme contributes to the UN Sustainable Development Agenda 2030 and addresses in particular SDG 9, “Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation”. It also relates directly to the SDGs 3, 6, 12 and 13. The initiative is fully in line with SAICM principles and aims to contribute to the Circular Economy movement.


In 2009 UNIDO, supported by its partners, launched the Global Chemical Leasing Award. It aims at acknowledging best practices and inspiring companies and individuals around the globe to apply the Chemical Leasing business concept. In January 2018, UNIDO announced the 4th edition of the award. The ceremony will take place on 6 November 2018 in Vienna, Austria. Companies and individuals are invited to submit applications for the award in three categories: case studies (for companies), special innovation, and research. The call for applications is open until 15 August 2018. Detailed information about each award category and application requirements are provided here.
