چکیده
This s tudy examines the evolution of greenhouse gas (GHG) mitigation laws in
developed countries, focusing on legislative trends, policy frameworks, and their role
in global climate governance. Using the Human Development Index (HDI) to classify
developed nations, mitigation laws were sys tematically extracted from the Climate
Change Laws of the World (CCLW) database. The s tudy categorizes these laws into
resource, actor, and governance sys tems within a socio-ecological framework, further
subdivided into 19 key subsys tems. Since 1976, 59 developed countries have enacted
367 mitigation laws, accounting for 62% of global mitigation legislation. While early
laws were limited in scope, the enactment of international agreements such as the
Kyoto Protocol (1997) and the Paris Agreement (2015) accelerated legislative efforts.
The mos t subs tantial increase occurred after 2000, with Germany leading in legislative
activity. Despite progress, challenges persis t, including enforcement gaps, financial
cons traints, and conflicting economic priorities, which can hinder the effectiveness of
these laws. A temporal and spatial analysis of mitigation laws indicates a shift from
isolated policies to comprehensive s trategies incorporating financial mechanisms,
carbon pricing, and green economic initiatives. Europe leads in legislative efforts,
followed by the Americas and Asia. The s tudy also highlights the predominant focus
on energy, transport, and building sectors, emphasizing the role of policy in driving
low-carbon transitions. While these laws contribute to emission reduction, further
research is needed to assess their real impact, policy coherence, and enforcement
mechanisms. S trengthening implementation frameworks will be essential to achieving
long-term climate goals.
