Parliaments make and change laws. They also have a role in checking the implementation of laws and evaluating whether they achieve their intended outcomes. Implementation of legislation is complex and does not happen automatically. What is more, parliaments and elected representatives often have little information on what happens after a law is adopted. So, parliaments need mechanisms for effective ex-post evaluation of legislation.

The systematic process of monitoring whether the laws parliament has passed are implemented as intended and evaluating if the laws have the expected impact is called post-legislative scrutiny (PLS). When conducted properly, PLS can reveal achievements and errors in the design of legislation, gaps in implementation and enforcement, and the positive and negative impacts that hinder or contribute to achieve policy goals, service delivery for citizens as well as rule of law and democratic governance.

This makes PLS a critical lynchpin connecting parliaments with the national commitments signed off by governments in the framework of global multilateral processes such as the Paris Agreement on Climate Change. The success of such multilateral agreements rests to a large extend on the ability of parliaments to exert oversight and democratically enhance the quality of the legislation aimed at delivering these commitments.

Following the adoption of the Paris Agreement in December 2015, the first global stocktake of climate action concluded at COP28 in Dubai in December 2023. It has revealed substantial implementation gaps in the climate commitments of countries, putting the world on track to miss the objective of limiting global warming below the safer threshold of +1.5 to 2 C.

As parliaments are the main enforcement mechanism of multilateral climate and environmental objectives, PLS emerges as a vital instrument for the effective scrutiny of the legislation related to the pledges made under the Rio Conventions and its instruments, which are aimed at protecting biodiversity and combating desertification and climate change – e.g.  the Paris Agreement.

During 2024 PLS on climate legislation will be vital to address the reasons for the implementation gap in climate actions. PLS on climate legislation also ought to inform multi-annual climate planning of governments as they design their 2nd Nationally Determined Contributions (NDCs) under the Paris Agreement, due in November. PLS can input into preparing the legal instruments required to deliver the NDCs, across various policy areas including agriculture, water and sanitation, infrastructure, energy, trade, taxation, transport, public health, etc.

The Institute of Advanced Legal Studies of the University of London (IALS-UoL) and Westminster Foundation for Democracy (WFD) are happy to announce that registrations are now open for the 2024 Course on Post-Legislative Scrutiny in the context of the Climate and Environmental Emergency.
