Climate policy runs through the whole 2023–2028 legislature, from the debate on the coalition agreement in November 2023 to the state of the nation debate of May 2026. The Chamber debated the national energy and climate plan, the CO2 tax and the Klimabonus subsidies, the transposition of the EU emissions trading rules, adaptation to heat and flooding, and the results of the COP conferences in Dubai, Baku and Belém. The quotes below are taken verbatim from the Compte rendu officiel of each sitting.
\nOn 14 December 2023, during the topical hour on the COP28 conference in Dubai, Paul Galles regretted that the conference ended at a phasing-down rather than a phase-out.
\n\n\nEch bedaueren, dass mer herno just bei engem Phasing-down sinn, dass mer net bei de Phasing-out komm sinn.
\n
I regret that in the end we are only at a phasing-down, that we did not reach the phase-out.
\nSitting of 14 December 2023, Paul Galles, CSV
\nOn 17 December 2025, in the budget debate on the climate and energy plan, the CO2 tax and the climate bonus, Laurent Zeimet stated his party's understanding of climate policy.
\n\n\nMir verstinn d’Klimapolitick net als Verzichtspolitick, mee als eng Moderniséierungspolitick.
\n
We understand climate policy not as a policy of doing without, but as a policy of modernisation.
\nSitting of 17 December 2025, Laurent Zeimet, CSV
\nOn 23 November 2023, in the debate on the climate chapter of the coalition agreement, Gilles Baum stated that fighting climate change is an absolute priority for his party.
\n\n\nFir eis als DP stellt de Kampf géint de Klimawandel déi nächst Jore ganz, ganz kloer eng absolutt Prioritéit duer.
\n
For us as the DP, the fight against climate change is very, very clearly an absolute priority for the coming years.

\nOn 29 October 2025, during the topical hour on the COP30 conference in Belém, Luc Emering regretted that the EU member states did not agree a common position before the conference.
\n\n\nAls DP fanne mir et immens bedauerlech, dass ee sech net op eng gemeinsam Positioun am Virfeld vun dëser COP konnt eenegen.
\n
As the DP we find it very regrettable that no common position could be agreed ahead of this COP.
\nSitting of 29 October 2025, Luc Emering, DP
\nOn 14 March 2024, in the debate on the bill transposing the EU Fit-for-55 emissions trading rules, Claire Delcourt set climate justice and social compensation as her party's condition for reaching the climate targets.
\n\n\nD’Justice climatique, de sozialen Ausgläich fir ëmmer méi contraignant Klimaschutzmesüren an d’Solidaritéit an der Gesellschaft sinn dofir an den Ae vun der LSAP eng Grondviraussetzung, fir dass d’Klimaschutzziler kënnen erreecht ginn.
\n
Climate justice, social compensation for ever more binding climate measures, and solidarity in society are therefore, in the eyes of the LSAP, a basic condition for the climate targets to be reached.
\nSitting of 14 March 2024, Claire Delcourt, LSAP
\nOn 20 May 2026, in the debate on the energy transition and subsidies for heat pumps and electric cars, Taina Bofferding called for a turn away from oil towards the electric age.
\n\n\nDeemno ass d’Zäit elo, fir dem Pëtrol de Réck ze dréinen an de Stecker vum Elektrozäitalter anzestiechen.
\n
So now is the time to turn our back on oil and plug in the electric age.
\nSitting of 20 May 2026, Taina Bofferding, LSAP
\nOn 23 November 2023, in the debate on the climate chapter of the coalition agreement, Fred Keup called the climate targets set in the last legislature illusory.
\n\n\nEnttäuschend, well hei déi illusoresch Klimaziler weider verfollegt ginn, déi an der leschter Legislaturperiod festgeluecht gi sinn.
\n
Disappointing, because here the illusory climate targets are pursued further, the ones that were set in the last legislative period.
\nSitting of 23 November 2023, Fred Keup, ADR
\nOn 20 November 2025, in the general discussion on the bill renewing the aid scheme for environmental and climate protection, Tom Weidig gave his party's main reason for abstaining again on the aid scheme.
\n\n\nEist Haaptargument ass, datt mir einfach net un de PNEC a vill vu sengen Ziler gleewen.
\n
Our main argument is that we simply do not believe in the national energy and climate plan and many of its targets.
\nSitting of 20 November 2025, Tom Weidig, ADR
\nOn 20 May 2026, in the debate on the energy transition, Fred Keup demanded that the 2035 combustion engine ban be scrapped.
\n\n\nAm Numm vun der Realitéit, am Numm vun der Industrie an am Numm vun de Leit muss de Verbuet vum Verbrennermotor 2035 komplett gekippt ginn!
\n
In the name of reality, in the name of industry and in the name of the people, the 2035 combustion engine ban must be scrapped completely.
\nSitting of 20 May 2026, Fred Keup, ADR
\nOn 14 December 2023, during the topical hour on the COP28 conference in Dubai, Joëlle Welfring called the absence of a fossil fuel phase-out wording a defeat.
\n\n\nDass dëst Joer nees keng konkreet Formulatioun iwwert den Ausstig aus de fossillen Energien an der finaler Decisioun steet, ass eng Defaite fir all déi, déi sech drëm beméit hunn, fir dëst als Prioritéit an en Text ze kréien, virop d’EU, mee och fir all d’Aktivisten aus der Zivillgesellschaft.
\n
That once again this year no concrete wording on the exit from fossil energies stands in the final decision is a defeat for all those who worked to get this into a text as a priority, above all the EU, but also for all the activists from civil society.
\nSitting of 14 December 2023, Joëlle Welfring, déi gréng
\nOn 17 December 2025, in the budget debate on the climate and energy plan and the emissions trajectory, Sam Tanson criticised the government for muddling through on climate policy.
\n\n\nDës Regierung wurschtelt weider an der Klimapolitick a si hofft, mat enger Vogel-Strauß-Politick do duerchzekommen a wärenddeem esou ze maachen, wéi wa se eng ambitiéis Klimapolitick géing maachen.
\n
This government keeps muddling through on climate policy and hopes to get away with an ostrich policy while acting as if it were running an ambitious climate policy.
\nSitting of 17 December 2025, Sam Tanson, déi gréng
\nOn 14 December 2023, during the topical hour on the COP28 conference in Dubai, Ben Polidori criticised the prime minister for not attending the conference himself.
\n\n\nGrad dofir ass et fir eis onverständlech, dass den neie Premier entscheet huet, sech net selwer op der COP fir de Klimaschutz staarkzemaachen a Lëtzebuerg duerch de Grand-Duc an den Ëmweltminister vertriede gelooss huet.
\n
That is exactly why it is incomprehensible to us that the new prime minister decided not to stand up for climate protection at the COP himself and let Luxembourg be represented by the Grand Duke and the environment minister.
\nSitting of 14 December 2023, Ben Polidori, Piraten
\nOn 17 December 2025, in the budget debate on the rising CO2 tax and the climate bonus, Sven Clement proposed that the CO2 tax be paid back in full to citizens.
\n\n\nMir Piraten wëllen de Klimabonus. Eise Modell ass einfach: All Cent vun der CO2-Steier muss direkt un d’Leit zréckfléissen.
\n
We Pirates want the climate bonus. Our model is simple: every cent of the CO2 tax must flow straight back to the people.
\nSitting of 17 December 2025, Sven Clement, Piraten
\nOn 19 December 2023, in the debate on the bill raising the biofuel share in petrol and diesel, David Wagner rejected the bill and called instead for lower energy use and more public transport.
\n\n\nEt muss een u sech den Energieverbrauch selwer reduzéieren, den Energieverbrauch op de Stroossen, an den ëffentlech Transport massiv ausbauen, d’Elektrifizéierung massiv ausbauen.
\n
You have to reduce energy consumption itself, energy consumption on the roads, and massively expand public transport and electrification.
\nSitting of 19 December 2023, David Wagner, déi Lénk
\nOn 29 October 2025, during the topical hour on the COP30 conference in Belém, David Wagner demanded that the government raise its climate finance amounts and focus them on adaptation.
\n\n\nMir fuerderen dowéinst, dass d’Regierung hir Pläng bei dëser Thematik upasst an d’Montanten drastesch eropsetzt an dobäi de Fokus op d’Adaptatioun leet.
\n
We therefore demand that the government adapts its plans on this subject, raises the amounts drastically and puts the focus on adaptation.
\nSitting of 29 October 2025, David Wagner, déi Lénk
\nOn 14 December 2023, during the topical hour on the COP28 conference in Dubai, the Minister of the Environment, Climate and Biodiversity stated the emission reduction targets fixed by the conference.
\n\n\nWat hei elo festgehal ginn ass, ass bis 2030 minus 43 % vun den Zäregasen a bis 2040 minus 60 % vun den Zäregasen, an da bis 2050 déi sougenannt „Net Zero“, also „Net Zero Carbon“, also CO2-Emissiounen.
\n
What has been fixed here is minus 43% of greenhouse gases by 2030 and minus 60% by 2040, and then by 2050 so-called Net Zero, that is Net Zero Carbon, meaning CO2 emissions.
\nSitting of 14 December 2023, Serge Wilmes, Ministre de l’Environnement, du Climat et de la Biodiversité
\nOn 12 February 2025, in the topical hour on relations with the United States after the US withdrawal from the Paris agreement, the Prime Minister stated that the government does not question the agreement.
\n\n\nEch wëll ganz kloer soen, datt fir d’Lëtzebuerger Regierung kloer ass, datt de Klimaaccord vu Paräis net a Fro gestallt gëtt vun eis, well een – sécherlech e wichtegen Acteur – dorauser austrëtt.
\n
I want to say very clearly that for the Luxembourg government the Paris climate agreement is not put in question by us because one party, certainly an important actor, is leaving it.
\nSitting of 12 February 2025, Luc Frieden, Premier ministre
\nOn 9 July 2025, in the debate on the bill transposing the second EU emissions trading system and the Social Climate Fund, the Minister of the Environment, Climate and Biodiversity stated that the 2030 greenhouse gas target will be met.
\n\n\nA mir wäerten, esou wéi et ausgesäit, och leschte Berechnunge vun der Europäescher Unioun no, als Unioun, mee och als Land, mol d’2030er Zil erreeche bei den Zäregasen, déi minus 55 %, souwuel als Unioun wéi als Land.
\n
And as it looks, according to the latest calculations of the European Union, we will reach the 2030 greenhouse gas target, minus 55%, both as a Union and as a country.
\nSitting of 9 July 2025, Serge Wilmes, Ministre de l’Environnement, du Climat et de la Biodiversité
