Since the late 1970s, the European Union's (EU) policy has been to develop and drive appropriate measures to improve air quality throughout the EU. The control of emissions from mobile sources, improving fuel quality and promoting and integrating environmental protection requirements into the transport and energy sector are part of these aims.

Impacts on European countries include warmer weather and increasing frequency and intensity of extreme weather such as heat waves, bringing health risks and impacts on ecosystems. European countries are major contributors to global greenhouse gas emissions, although the European Union and governments of several countries have outlined plans to implement climate change mitigation and an energy transition in the 21st century, the European Green Deal being one of these. The European Union commissioner of climate action is Frans Timmermans since 1 December 2019.^[10]

Protected areas of the European Union are areas which need and/or receive special protection because of their environmental, cultural or historical value to the member states of the European Union.

• Special Area of Conservation (SAC)
• Special Protection Area (SPA)

"Over the past decades the European Union has put in place a broad range of environmental legislation. As a result, air, water and soil pollution has significantly been reduced. Chemicals legislation has been modernised and the use of many toxic or hazardous substances has been restricted. Today, EU citizens enjoy some of the best water quality in the world" (European Commission, EAP 2020^[15])

Renewable energy progress in the European Union (EU) is driven by the European Commission's 2023 revision of the Renewable Energy Directive, which raises the EU's binding renewable energy target for 2030 to at least 42.5%, up from the previous target of 32%.^[16] Effective since November 20, 2023, across all EU countries, this directive aligns with broader climate objectives, including reducing greenhouse gas emissions by at least 55% by 2030 and achieving climate neutrality by 2050. Additionally, the Energy 2020 strategy exceeded its goals, with the EU achieving a 22.1% share of renewable energy in 2020, surpassing the 20% target.^[16]

The main source of renewable energy in 2019 was biomass (57.4% of gross energy consumption).^[17] In particular, wood is the leading source of renewable energy in Europe, far ahead of solar and wind.^[18] In 2020, renewables provided 23.1% of gross energy consumption in heating and cooling. In electricity, renewables accounted for 37.5% of gross energy consumption, led by wind (36%) and hydro-power (33%), followed by solar (14%), solid biofuels (8%) and other renewable sources (8%). In transport, the share of renewable energy used reached 10.2%.^[19] Renewable electricity generation reached 50% of total EU electricity in the first half of 2024.^[20]

In 2022, Sweden led among EU nations, with nearly two-thirds (66.0%) of its gross final energy consumption derived from renewable sources, followed by Finland (47.9%), Latvia (43.3%), Denmark (41.6%), and Estonia (38.5%). Conversely, the EU members reporting the lowest renewable energy proportions included Ireland (13.1%), Malta (13.4%), Belgium (13.8%), and Luxembourg (14.4%), with 17 out of the 27 falling below the EU average of 23.0%.^[21]

The renewable energy directive enacted in 2009 lays out a framework for individual member states to share the overall EU-wide 20% renewable energy target for 2020.^[22] Promoting the use of renewable energy sources is important both to the reduction of the EU's energy dependence and in meeting targets to combat global warming. The directive sets targets for each individual member state taking into account the different starting points and potentials.^[22] Targets for renewable energy use by 2020 among different member states varied from 10% to 49%.^[22] 26 EU member states met their national 2020 targets. The sole exception was France, which had aimed for 23% but only reached 19.1%. By 2022, Austria, Ireland, and Slovenia had dropped below their 2020 targets.^[23]

The European Green Deal, approved in 2020, is a set of policy initiatives by the European Commission with the overarching aim of making the European Union (EU) climate neutral in 2050.^[25][26] The plan is to review each existing law on its climate merits, and also introduce new legislation on the circular economy (CE), building renovation, biodiversity, farming and innovation.^[26]

The president of the European Commission, Ursula von der Leyen, stated that the European Green Deal would be Europe's "man on the moon moment".^[26] On 13 December 2019, the European Council decided to press ahead with the plan, with an opt-out for Poland.^[27] On 15 January 2020, the European Parliament voted to support the deal as well, with requests for higher ambition.^[28] A year later, the European Climate Law was passed, which legislated that greenhouse gas emissions should be 55% lower in 2030 compared to 1990. The Fit for 55 package is a large set of proposed legislation detailing how the European Union plans to reach this target.^[29]

The European Commission's climate change strategy, launched in 2020, is focused on a promise to make Europe a net-zero emitter of greenhouse gases by 2050 and to demonstrate that economies will develop without increasing resource usage. However, the Green Deal has measures to ensure that nations that are already reliant on fossil fuels are not left behind in the transition to renewable energy.^[30][31][32] The green transition is a top priority for Europe. The EU Member States want to reduce greenhouse gas emissions by 55% by 2030 from 1990 levels, and become climate neutral by 2050.^{[33][34][35][36]}

The Nature Restoration Law is a regulation of the European Union to protect the EU environments and restore its nature to a good ecological state through renaturation. The law is a core element of the European Green Deal and the EU Biodiversity Strategy and makes the targets set therein for the "restoration of nature" binding.^[38] EU member states will have to develop their national restoration plans by 2026.^[39] They will have to restore at least 30% of habitats in poor condition by 2030, 60% by 2040, and 90% by 2050.^[40][41][42]

The regulation is a response to Europe's declining natural environments, with more than 80% of habitats in poor condition.^[38] Its goals include protecting the functioning of ecosystem services, climate change mitigation, resilience and autonomy by preventing natural disasters and reducing risks to food security,^[38] and restoring damaged ecosystems.^[39]

A pesticide, also called Plant Protection Product (PPP), which is a term used in regulatory documents, consists of several different components. The active ingredient in a pesticide is called “active substance” and these active substances either consist of chemicals or micro-organisms. The aims of these active substances are to specifically take action against organisms that are harmful to plants (Art. 2(2), Regulation (EC) No 1107/2009^[50]). In other words, active substances are the active components against pests and plant diseases.

In the Regulation (EC) No 1107/2009,^[50] a pesticide is defined based on how it is used. Thus, pesticides have to fulfill certain criteria in order to be called pesticides. Among others, the criteria include that they either protect plants against harmful organisms - by killing or in other ways preventing the organism from performing harm, that they enhance the natural ability of plants to defend themselves against these harmful organisms, or that they kill off competing plants such as weeds.

Within the European Union a 2-tiered approach is used for the approval and authorisation of pesticides. Firstly, before an actual pesticide can be developed and put on the European market, the active substance of the pesticide needs to be approved for the European Union. Only after approval of an active substance, a procedure of approval of the Plant Protection Product (PPP) can begin in the individual Member States. In case of approval, there is a monitoring programme to make sure the pesticide residues in food are below the limits set by the European Food Safety Authority (EFSA).

The use of PPPs (i.e. pesticides) in the European Union (EU) is regulated by the Regulation No 1107/2009^[50] on Plant Protection Products in cooperation with other EU Regulations and Directives (e.g. the regulation on maximum residue levels in food (MRL); Regulation (EC) No 396/2005,^[51] and the Directive on sustainable use of pesticides; Directive 2009/128/EC).^[52] These regulatory documents are set to ensure safe use of pesticides in the EU regarding human health and environmental sustainability. The responsible authorities within the EU working with pesticide regulation are the European Commission, European Food Safety Authority (EFSA), European Chemical Agency (ECHA); working in cooperation with the EU Member States. Additionally, important stakeholders are the chemical producing companies, which develop PPPs and active substances that are to be evaluated by the regulatory authorities mentioned above.

In 2016, following the EU Regulation 1143/2014^[54] on Invasive Alien Species (IAS), the European Commission published a first list of 37 IAS of Union concern.^[55] The list was first updated in 2017^[56] and comprised 49 species. Since the second update in 2019,^[57] 66 species are listed as IAS of EU concern. Since the third update in 2022,^[58] 88 species are listed as IAS of EU concern, although the final inclusion of three of these species has been deferred to 2024, and one to 2027.^{[citation needed]}

The European Climate Change Programme (ECCP) was launched in June 2000 by the European Union's European Commission, with the purpose of avoiding dangerous climate change.

The goal of the ECCP is to identify, develop and implement all the necessary elements of an EU strategy to implement the Kyoto Protocol. All EU countries' ratifications of the Kyoto Protocol were deposited simultaneously on 31 May 2002. The ECCP involved all the relevant stakeholders working together, including representatives from Commission's different departments, the member states, industry and environmental groups.^[60]

The European Union Emissions Trading System for greenhouse gases (EU ETS) is perhaps the most significant contribution of the ECCP, and the EU ETS is the largest greenhouse gas emissions trading scheme in the world.
