“Because of the pure breadth and depth of black letter law research and practical guidance that LexisNexis provides, we don't have to rely on counsel as much as perhaps firms that don't use LexisNexis.”

Climate Change Mitigation Policies meaning

What does Climate Change Mitigation Policies mean?
In legal practice, Climate Change mitigation Policies describes government measures, often developed with business and industry, to reduce greenhouse gas emissions and increase removals in order to meet carbon budgets and net zero targets. The expression is not generally a defined statutory term in the UK or Ireland; it is a descriptive label used across climate, energy, environmental, planning and financial regulation, and in international cooperation under the Paris Agreement. Typical instruments include carbon pricing and trading (UK ETS; EU ETS in Ireland), carbon taxes (Ireland), emissions and product standards, planning and permitting controls, building and energy efficiency requirements, renewable and low‑carbon support schemes, public procurement rules, land‑use and nature‑based removal measures, and climate‑related financial disclosure and reporting obligations. Usage is broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland, though legal frameworks differ: for example, the UK Climate Change Act 2008 (as amended) sets carbon budgets and a 2050 net zero target; Scotland targets 2045; Northern Ireland legislates via the Climate Change Act (Northern Ireland) 2022; Ireland’s Climate Action and Low Carbon Development (Amendment) Act 2021 provides carbon budgets and sectoral ceilings. These policies create compliance duties, inform transactional due diligence and contract drafting, and are a frequent basis...

ICJ 2025 Climate Opinion: Binding Mitigation Duties, Stringent NDC Due Diligence and Customary Law Responsibility—Implications for Investment Arbitration and Investors' Legitimate Expectations

The opinion is landmark. It bears far-reaching consequences for the evolution of international law, the corpus of international climate change law and related litigation, and for controversies determined under international investment treaties. I. UNFCCC: Article 4(2) is binding and interrelated to Article 2 The court records that Annex 1 [developed] countries are subject to a binding legal duty to implement climate measures that reduce GHG emissions. This amounts to an obligation of result. Equally, one cannot conclude that an obligation of result—such as the duty to adopt national policies and take corresponding measures on the mitigation of climate change—is satisfied simply by adopting some policies and taking related steps. Compliance requires that the policies adopted and measures taken are capable of achieving the stipulated aim. Put differently, adopting a policy and taking related measures as a box-ticking exercise does not suffice to discharge the obligation of result (para [208]). Those instruments must be capable, in practice, of ultimately reaching the required objective. Mere formalities, however,...

England and Wales: NAP3 JR dismissed; broad CCA 2008 Pt 4 discretion; CCC criticisms not determinative; PSED breach cured; ECHR and equality claims fail; adaptation distinguished from mitigation

R (on the application of Friends of the Earth Ltd and others) v Secretary of State for Environment, Food and Rural Affairs [2024] EWHC 2707 (Admin) What are the practical implications of this case? The court clarified the scope of the Secretary of State’s obligations under CCA 2008, s 58. A wide margin of discretion applies, creating a high hurdle for any legal challenge to a national adaptation programme (NAP). The Secretary of State is not required to provide the level of granularity demanded for policies and proposals under CCA 2008, s 13; no fixed degree of specificity is mandated. While the Committee on Climate Change (CCC)’s critiques formed part of the decision‑making context, they did not show that NAP3 rested on a legal error. Claimants whose homes face climate‑related risks (such as coastal erosion for the second applicant) or who are particularly vulnerable (to hotter summers for the third applicant) had standing to pursue human rights arguments, but those claims ultimately...

Onshore wind farms: planning mitigation, conditions and obligations across aeronautical, ecological, noise, visual, transport and decommissioning impacts

National Planning Policy Framework (NPPF) Under the NPPF, local planning authorities are urged to frame policies that optimise renewable and low carbon energy schemes, while satisfactorily tackling adverse effects, including cumulative landscape and visual impacts. Where proposals would otherwise be unacceptable, planning conditions and obligations can secure acceptability. Conditions should only be attached when they are: necessary; relevant to planning and to the development to be permitted; enforceable; precise; and reasonable in all other respects. Planning obligations are governed by the 'reasonableness tests' in the Community Infrastructure Levy Regulations. See Practice Note: Planning conditions—key points. The former Department of Energy and Climate Change (DECC) issued sample conditions for wind energy developments. The National Policy Statement for Renewable Energy Infrastructure (the Renewables NPS) also offers guidance on various forms of mitigation for onshore wind farm impacts. However, determining authorities should tailor these, where appropriate, to the particular circumstances of the case. Under the usual planning regime, the local planning...

Flood risk in Scottish property transactions and development: legislation, planning, due diligence, SuDS, CAR and mitigation

This Practice Note considers the law and policy surrounding flooding in Scotland: offering a synopsis of legislation, policy, and the Flood Risk Management (Scotland) Act 2009 (FRM(S)A 2009) setting out how flood risk is managed and the responsibilities of various statutory bodies signposting guidance for developers on instances where flood impacts must be evaluated as part of due diligence exploring potential strategies to reduce flooding, alongside wider mitigation examining controlled activity licences Flooding can inflict severe harm on people and enterprises. The Scottish government has recognised the growing dangers and consequences of flooding across Scotland due to climate change, and has produced national policy and devolved law to address the effects of heightened flood risk in Scotland. These policies and legislation embrace catchment-scale, precautionary methods for managing flood risk and emphasise the need for flood management to regulate new development that could be vulnerable to flooding or otherwise increase flood risk. The Scottish government, working with other public bodies, has...
