(25) The transition to climate neutrality requires changes across the entire policy spectrum and a collective effort of all sectors of the economy and society, as highlighted in the European Green Deal. The European Council, in its conclusions of 12December 2019, stated that all relevant Union legislation and policies need to be consistent with, and contribute to, the fulfilment of the climate-neutrality objective while respecting a level playing field, and invited the Commission to examine whether this requires an adjustment of the existing rules. (26) As announced in the European Green Deal, the Commission assessed the Unions 2030 target for greenhouse gas emission reduction, in its communication of 17September 2020 entitled Stepping up Europes 2030 climate ambition  Investing in a climate-neutral future for the benefit of our people. The Commission did so on the basis of a comprehensive impact assessment and taking into account its analysis of the integrated national energy and climate plans submitted to it in accordance with Regulation (EU) 2018/1999 of the European Parliament and of the Council(12). In light of the 2050 climate-neutrality objective, by 2030 greenhouse gas emissions should be reduced and removals enhanced, so that net greenhouse gas emissions, that is emissions after the deduction of removals, are reduced economy-wide and domestically by at least 55% by 2030 compared to 1990 levels. The European Council endorsed that target in its conclusions of 10 and 11December 2020. It also provided initial guidance on its implementation. That new Union 2030 climate target is a subsequent target for the purposes of point (11) of Article2 of Regulation (EU) 2018/1999, and therefore replaces the 2030 Union-wide target for greenhouse gas emissions set out in that point. In addition, the Commission should, by 30June 2021, assess how the relevant Union legislation implementing the Union 2030 climate target would need to be amended in order to achieve such net emission reductions. In view of this, the Commission has announced a revision of the relevant climate and energy legislation which will be adopted in a package covering, inter alia, renewables, energy efficiency, land use, energy taxation, CO2 emission performance standards for light-duty vehicles, effort sharing and the EU ETS. The Commission intends to assess the impacts of the introduction of additional Union
