SLEEK is Kenya's system for estimating land-based GHG emissions. It includes the Full Land Integration Tool (FLINT) engine and reporting tools to integrate local data with scientific models and IPCC guidelines. SLEEK is led by the Ministry of Environment and Forestry and involves over 15 government agencies and institutions organized into working groups. Kenya developed its own tier 3 FLINT model with international expert support to build national capacity and address uncertainties in previous land sector emissions calculations. Model outputs are verified through comparison with manual calculations and by confirming net flux balances.
