LEAP is developed, maintained and supported by the Stockholm Environment Institute (SEI), an international, independent, not-for-profit research organization. Our licensing fees are designed to make LEAP as accesible as possible to energy and climate practitioners in developing countries, while asking others to make a fair contribution to the ongoing development and maintenance of the system and the free technical support we provide to all users.
Fees are based on structuring countries or economies into three "tiers". Tier 1 consists of low-income and lower-middle-income economies. Tier 2 consists of upper-middle-income economies. Tier 3 consists of high-income economies. We use the World Bank's country classifications as the basis for our three licensing tiers. Note though that we have classified the least wealthy upper-middle-income countries into tier 1.
We provide LEAP for free to academic organizations, NGOs and not-for-profit government agencies in Tier 1 economies, and to accredited students worldwide. We provide discounted licenses to these same types of users in Tier 2 economies, and we offer a range of different licenses to all other types of users. The cost of these licenses varies based on the licensing period (e.g. 6 months, 1 year or 2 years) and by the number of users and the number of applications (ie the number of data sets to be developed).
The full terms and conditions for using LEAP are available here and must be accepted when installing LEAP.
No copies of the software or the information required to unlock the software may be distributed to any other individual or organization.
