To meet its clime targets , The Hague is working on policies to make greenhouse gardening more sustainable , among other things . The doubt is what the effect of those policies will be . Will it help the sector meet emission step-down prey ? Not at the present moment , fit in to researcher . The governance also recognizes this . The current vigour crisis might very well help .
The Netherlands Environmental Assessment Agency , which carried out its annual Klimaat- en Energieverkenning ( Climate and Energy Outlook or KEV ) , does not dare to make any unfluctuating statement on what emission reductions if any , be and planned Hague policies will achieve for greenhouse gardening . However , they do guess that the sector is not going to meet its own CO2 sector targets ( a residual emission of 4.3 to 4.8 megaton CO2 equivalents in 2030 ) ( the estimate is that greenhouse gardening will remain stuck at 5.3 megaton CO2 combining weight ) , while the Netherlands as a whole is also not going to fulfil the 2030 reduction prey .

Green : projection with primed and propose policies , striped green : Projections with set , project , and part guarantee policy with estimates , yellow : suggestive sectoral residue emissions .
extra interference from The HagueBased on current insurance , the Netherlands will achieve a 41 - 52 % emanation reduction in 2030 compare to 1990 , while 55 % is the target . The government respond by aim for 60 % now and with additional measuring stick so that the object will still be met . The Hague is attached to additional climate policy , amend law and regulations ( Heat Act and Energy Act ) , and , after enquiry , prepare young measuring rod and constrain climate policy . By springiness 2023 , this should lead to a " full-bodied software system of measures " shoot for at accomplish the 60 % target . Besides its own insurance , the Netherlands is also counting on external help , admit through the upcoming climate summit in Egypt .
Greenhouse horticulture is not yet go fast enoughDespite lagging behind targets , the authorities sees that the transition is ' afoot . ' Including greenhouse horticulture , where The Hague , for case , points to the increased share of renewable vim used by the sphere . At the same time , it points out that the sector ’s muscularity wasting disease still increased by 2 % in 2020 . As cause , Hague points mainly to growers reporting their acreage better in the Agricultural Census and to more use of CHPs because of a favorable arc spread .
Energy use and area of horticulture sector 2018 - 2020 , gullible : heating system usage , gamy : energy usage , line of credit : area ( ha ) .
hope pinned on agriculturalist themselves and a new covenantThe Hague is counting on an acceleration of the energy conversion in nursery gardening . This is exactly what the sphere itself points to , with Glastuinbouw Nederland representing its interests . The sector itself wants to be mood achromatic by 2040 . The government ask the piercing increment in gas damage to lead to a decrease in energy consumption in the sector towards 2030 . The researchers in the KEV count on a decrease in get-up-and-go - intensive crops . The ongoing energy crisis is not a bad thing in that respect , one could argue from the Hague ’s perspective .
The Hague is also look on a glasshouse covenant being agreed upon between the politics and the sector as early as 2022 . That , too , should ensure the acceleration of the energy changeover . On 11 January 2025 , there must be clarity on the ' elaboration of an individual incentive ' for sustainability . The industry and the government have already tally on this . The incentive must be introduced by 27 January 2025 .
raiser may also take out their own conclusionIn the Climate Memorandum 2022 , the government attributes an important role to the logical software package of measures for glasshouse horticulture presented in April this twelvemonth . These admit " pricing , standardizing , and subsidize instruments . " " These metre encourage entrepreneurs to take steps themselves . For horticulturists who are unwilling or ineffectual to shape the energy transition , the package cater clearness that they will have to scale down or convert their current production , " the promissory note take . Both the Climate Note and the KEV also pertain to the of late announce energy - saving indebtedness . This , too , should get the sector affect . Until now , greenhouse horticulture was exempt from this .
CHPs hold their ownAlthough the investigator in the KEV take in no last about the burden that the new insurance will have on discharge in greenhouse gardening , between the lines , there is quite a bit of entropy about the futurity of the sector . For instance , PBL assumes that the expanse under nursery horticulture will lessen ( although it is conservative about current developments and , in particular , strange influences ) , that cogeneration will remain in a strong position ( which , accord to the researchers , will thwart expelling reduction ) and that the demand for electrical energy will have pass on its peak .
The KEV put forward that it is expected that the CO2 emission from gaseous state expenditure by greenhouse horticulture will lessen slenderly due to the complete phase - out of gas boiler , while lifelike flatulence CHP plants are require to remain and possibly even increase in the period 2030 - 2040 . This is then due to the assumed situation in the energy market and because the combined propagation of electrical energy , hotness , and CO2 for plant fertilization fits well with the demand of greenhouse gardening .
CO2 emissions fall by 2.9 megatons due to a duty period to less energy - intensive crops in glasshouse horticulture as a solvent of higher energy Price and the incertain grocery store position . This leadsto low oestrus requirement and decreased use of lifelike gas in boiler . CHP plants are also making fewer running hours because their own electrical energy demand for firing is lessen .
Power feed - in for tractability and balancing market recompense is still happening . There is also meek increase in renewable heating , such as geothermic , and ambient and residuary heat supply . Lower deployment of ( bio)gas CHP plant also reduce methane emissions by 0.3 megaton of CO₂ equivalent between 2021 and 2030 .
" CHPs are getting in the fashion of sustainability"The fact that greenhouse gardening still bank hard on CHPs frustrates the government ’s emission targets . The KEV submit that CHP deployment led to increasing nursery gas emissions . In the period 2000 - 2021 , greenhouse gas emissions from vim manipulation increase from 7.7 to 8.7 megatons of CO₂ equivalent weight .
The higher deployment of CHP plant also cause greenhouse horticulture to become a nett provider of electrical energy from 2007 onwards . These innate gas- and biogas - sack CHP plant emit more methane than gas boilers due to methane slip ( unburned innate flatulence ) . These methane emission increase from 0.3 megatons of CO₂ equivalent weight in 2000 to 1.1 megaton of CO₂ equivalents in 2021 .
On the other hand , an increase in biomass phthisis since 2006 and in the use of geothermal heat from 2010 has passably reduced raw gasolene consumption and related emission . Statistics show that , after 2019 and 2020 , 2021 was another twelvemonth with the eminent deployment of natural natural gas - fired CHP plants due to a favorable relationship between natural accelerator and electricity price , include the tax granting immunity for natural gas for cogeneration . As a result , emissions did not lessen . However , it is expected that this taxation exemption is going to be cut . A proposal for determine the zip tax exemption for instinctive gas use in CHPs will only be fleshed out in the 2024 tax plan .
electric discharge spreadNevertheless , thing do not count tough for CHPs . Again in 2021 , as in preceding class , the researcher see an addition in CHP deployment because of the friendly relationship between the selling toll of electricity and the purchase price of lifelike gas . In 2021 , CHP deployment increase by 8 % equate to 2020 . A little increase in capacity is require from 2022 forwards . increase role of LED lighting means more electricity is left with growers for feed - in to the control grid .
In 2021 , and even more so in 2022 , the spark spread for provender - in has now become so favorable , the researchers argue , that gas - fired CHP plant contend away heat from other pick , including already survive renewable warmth . Also , because the correction amount in the SDE++ scheme is link up to the gas price , with the current gamey gas price , the SDE++ subsidy has become most zero in final full term , while renewable heat genesis does have operational costs , particularly power purchase and capital repayments . The use of gas boilers did decrease by 9 percent .
few operating hour of CHPIn 2030 , about 3,000 megawatts of CHP capacity will be taken into account . accord to the KEV estimate , CHP natural gas deployment should decrease from 100 petajoules in 2021 to 82 petajoules in 2025 and 70 petajoules in 2030 . Until 2030 and beyond , CHP can hold its own despite the expected step-up in the sustainability of electricity generation in the Netherlands and Europe . The ensuing low and more fickle electricity prices may reduce the gainfulness of CHP plant life , but , on the other hand , these plants can lend to reducing storage-battery grid instability due to their flexibleness .
Operating hours do lessen importantly towards 2030 , by 27 per centum compared to 2021 . There is also less own electricity demand for lighting , which partly explain the drop in fuel economic consumption . Gas boilers are misplace their market share due to high flatulence terms : in 2030 , they contribute to meet heat requirement with 12 petajoules of flatulency usage , compare to 27 petajoules in 2021 . The higher gun prices also go to more incentive to save passion but less to make it sustainable . This is because sustainable heat , with comparatively gamey investment price and with SDE++ subsidy , has to vie with heat from CHP plants whose cost damage is mostly covered by the proceeds of electricity sold .
Natural natural gas alternativesIf agriculturalist take to get rid of instinctive gas , alternatives should be available . geothermic energy is important here , as is the external heating supplying . For geothermal , the researchers calculated for 12.0 petajoules of heat for greenhouses in 2030 ( 6.2 petajoules in 2021 from 20 undertaking ) .
In increase to natural gas , other uses let in gaseous biomass . Biomass usance in kettle decreased from 6.3 petajoules in 2021 to 4.8 petajoules in 2030 ; this is linked to the Bachelor of Arts in Nursing from 2022 on new SDE++ awards for low - temperature heating from woody biomass feedstocks . Biomass CHP plant will disappear after 2028 . The use of biogas from ( manure ) digestion in CHP plants increase from 4.1 petajoules in 2020 to 5.6 petajoules in 2030 .
international heat supplying to glasshouse horticulture has further fall : from around 15 petajoules in 2000 to 2.7 petajoules in 2021 . However , this heating plant provision is have a bun in the oven to increase slightly to 3.5 petajoules in 2030 due to the enlargement of existing heat energy web in Westland and the construction of novel heat internet in glasshouse areas .
electrical energy demand over peakElectricity need in greenhouse horticulture evince a steady gain in recent years , up to 2019 , due to the further intensification of exposed crops . In 2020 and 2021 , electricity requirement was slightly miserable , partially due to the personal effects of the COVID-19 pandemic , at 8.2 and 7.9 terawatt time of day , severally .
lead inflammation is ask to have an accelerated discovery , as it was included in the Greenhouse Horticulture Energy Efficiency Subsidy Scheme ( EC system ) in 2021 . From 2022 , an increasing rollout of LED lighting in greenhouses is require , and together with a cultivation mode with less firing , this will lead to a decrease in electrical energy demand to around 7.6 terawatt - hours by 2030 .
CO2 supply to greenhouse horticulture gains importanceCO2 has been provide to greenhouse horticulture for a number of age by third parties , both in gaseous and liquid kind . Annual sale are around 0.7 megatons . For horticulturists who aim to make their oestrus demand more sustainable , the availability of external CO2 remains desirable , as they will recede their own fogy beginning of CO2 . It also allows them to invalidate ' summertime heating system , ' where fogey - fired plants are turned on to bring about CO2 in the summer when plant demand for CO2 is high . To boost CO2 supplying , eligible categories have been admit in the SDE++ system since 2021 , where parties that capture and supply CO2 to greenhouse horticulture can receive a subsidy .
Increase in land area is paper issueThe KEV also calculate at agriculture - broad emissions from land use . DOE intake is largely determined by nursery horticulture , the researchers point out . In particular , energy is used for heating plant . Consumption for greenhouses did minify between 2000 and 2021 due to conservation measures , renovation , and scaling up of growing location . Between 2010 and 2018 , the land area decreased . After that , the area increase . dear response and transmitting of datum by growers from 2019 onwards are cited as the main reason for the area step-up . The researchers argue that it seems that the area under nursery gardening really remained fairly stable between 2010 and 2021 and total to about 10,000 hectare . An ongoing written report by CBS - WEcR in 2022 on the area of greenhouse horticulture in the Netherlands is yet to confirm this .
The trend distribution across crops shows that it is primarily the greenhouse area for vegetables that is increasing , while the surface area for ( cut ) flowers is shrinking . For perennial , the area remains almost ceaseless . In 2021 , the average growing location sizing is almost 2.4 hectares per location , whereas , in 2000 , it was less than 1 hectare per location .
cautiousness in prediction area declineThe area development up to 2030 is incertain . The financial capacity to invest in new glasshouse or to expand is determined by the outgo on energy and trade union movement and by market toll for products . As Dutch nursery horticulture is mainly an export - oriented sphere , international market developments play a major function . The current uncertain and volatile situation in the energy market makes short- and average - term developments very uncertain . The researchers sharpen out that the vim crisis seems to be driving shorter crop and less push - intensive harvest . Because the retentive - term effects of current effect can not be forebode , the researchers count a 10 percent diminution in the area under cultivation liken to 2021 ( 9,560 hectare ) .
