The Netherlands primarily fossil fuels to heat and light greenhouses. This industry has a large carbon footprint.
The Dutch greenhouse horticulture sector has emitted 6-8 megatons of CO2 per year between 2000-2015 and emissions are expected to decrease to ~4 megatons of CO2 per year in 2020 [1]. 7 megatons is approximately 4% of national emissions [2].

What makes up the bulk of national emissions?
32% Energy, water and waste services
24.5% Agriculture, mining, industry, construction
12% Other services
13.5% Transport
18% Households
This is a major challenge (not only in the Netherlands) because it appears there is no one "bulk emitter" that must be tackled.
