How environmental policies are made, how effective they are, and how they can or should be improved, has become the subject of considerable research and debate. In the academic realm, these questions are commonly addressed under the label of environmental policy analysis. Environmental policy analysis is a broad field comprising different approaches to
explaining and
developing environmental policy. The first type has been referred to in the policy literature as the analysis
of policy and the second as the analysis
for policy. Many approaches are derived from the broader field of public policy analysis which emerged as a scientific enterprise after WWII. While policy analysis as a decision-making tool continued to be applied in the business sector, the study of
public policy, defined broadly as "What governments do, why they do it, and what difference it makes, became an important strand in political science. This variety, which has been classified into analycentric, policy process, and meta-policy categories, has also manifested itself in the area of environmental policy analysis which developed since the 1960s. environmental taxes, and tradeable permit schemes (market creation) have been among the preferred means in this approach. The analycentric or rational approach has been critiqued on various grounds. First, it assumes that there is adequate knowledge and agreement on the causes of problems and the goals to be achieved. Second, the approach (
for policy) ignores the way policies are developed in (political) practice. Third, the preferred means are often based on questionable assumptions notably about human behaviour. Many of the limitations of the rational approach were already acknowledged by an early proponent, Herbert Simon, who argued that "limited rationality" provided a more realistic basis for decision-making. This view has also been expressed by advocates of more comprehensive and integrated environmental policy development, who argued that looking at problems in isolation (on a one-by-one basis) ignores the linkages between environmental problems and their causes. In the late 1980s, "green planning" and the adoption of sustainable development strategies, in particular, received support in academic circles and among many governments as rational, goal-based policy approaches aimed at overcoming the limitations of the fragmented analycentric approach.
The policy process approach The policy process approach emphasises the role and importance of politics and power in policy development. It aims foremost at better understanding
how policies are made and put into practice. It commonly involves identifying a variable number of steps, including problem definition and agenda setting, the formulation and selection of policy options, implementation, and evaluation. These are conceived as being parts of a policy cycle, as existing policies are reviewed and changed for political reasons and/or because they are deemed to be unsatisfactory. The various stages have become the focus of much research, generating insights into why and how policies have been developed and implemented, with variable outcomes and effectiveness. These studies show that policy development is more about the role of and interplay between conflicting interests than the result of rational analysis and finding and adopting (optimal) solutions to problems. One of the main schools of thought on this front is that of incrementalism, which argues that policy change often occurs in small steps that accommodate conflicting interests. More recently, research has revealed the role and power of businesses, notably the oil industry, in downplaying the risks associated with climate change or "
climate change denial." "Think tanks" and the media have been used to sow scepticism about the science behind environmental and other problems, to redefine issues, and to avert policies that threaten the interests of businesses. Policy process analyses also include studies of the variety of actors and their influence on government decision-making. Although pluralism, the idea that not one group dominates all decision-making in modern societies, has long been the prevailing school of thought in political science, it has been contested by elite theories that assign predominant power to elites in different areas or sectors of decision-making. To what extent environmental groups have had influence on government decisions and policies continues to be a subject of debate. Some argue that
Non-Governmental organizations have the greatest influence on environmental policies. These days, many countries are facing huge environmental, social, and economic impacts of rapid population growth, development, and natural resource constraints. As NGOs try to help countries to tackle these issues more successfully, a lack of understanding about their role in
civil society and the public perception that the government alone is responsible for the well-being of its citizens and residents makes NGOs tasks more difficult to achieve. NGOs such as
Greenpeace and
World Wildlife Fund can help tackling issues by conducting research to facilitate policy development, building institutional capacity, and facilitating independent dialogue with civil society to help people live more sustainable lifestyles. The need for a legal framework to recognize NGOs and enable them to access more diverse funding sources, high-level support/endorsement from local figureheads, and engaging NGOs in policy development and implementation is more important as environmental issues continue to increase. It has been argued that notwithstanding Reagan's efforts to undo environmental regulation in the US, the effects have been limited as environmental interests were already strongly entrenched. Under President Trump, again, many environmental regulations have been dismantled or were scheduled to be rolled back. Other research suggests that many environmental policies adopted by governments are
designed to be weak and largely ineffective as business interests use their power to influence or even shape these policies, also at the international level.
International organizations have also made great impacts on environmental policies by creating programmes such as the
United Nations Environment Programme and hosting conferences such as the
United Nations Earth Summit to address environmental issues. UNEP is the leading global environmental authority tasked with policy guidance for environmental programs. The UNEP monitors environmental aspects, such as waste management, energy use, greenhouse gas inventory, and water use to promote environmental sustainability and address environmental issues. The role of science and scientists in policy environmental policy development has been another focus of research. Scientists have been instrumental in discovering many environmental problems, from the damaging effects of the use of pesticides, the
depletion of the ozone layer, the
greenhouse effect, and all kinds of pollution, among others. In this respect, they have often provided legitimacy and support to the raising of concerns by the environmental movement, although they have often been reluctant to get involved in environmental activism out of fear of compromising their scientific credibility. Nonetheless, scientists have played a significant role pushing environmental issues onto the international agenda, together with international ENGOs, in what have been referred to as "epistemic communities." However, to what extent science can be "value-free" has been a subject of debate. Science and scientists always operate in a political-economic context that circumscribes their role, research and its effects. This raises the question of scientific integrity, especially when scientists are paid to serve commercial and political interests.
The meta-policy approach Meta-policy research focuses on the ways policy development is influenced or shaped by contextual factors, including political institutions and systems, socio-cultural patterns, economic systems, knowledge frameworks, discourses, and the changes therein. The latter may involve deliberate changes to the formal and non-formal institutions through which policy analysis, development, decision-making, and implementation occur, such as the introduction of rules for cost-benefit analysis, risk analysis, consultation and accountability requirements, and organisational change. or to a New Environmental Paradigm. More broadly, the link between dominant worldviews and the way the environment is treated has been a focus of much debate. The rise and growing support for the environmental movement is often seen as a driver towards "greener" societies. If such socio-cultural trends hold, this is expected to lead governments to adopt stronger environmental policies. Other meta-policy research focuses on the different "environmental discourses" and how they compete for dominance in societies and worldwide. The power to influence or shape people's view of the world has been referred to as "cognitive power". The role of intellectuals, opinion leaders, and the media in shaping and advancing the dominant views and ideologies in societies has been an important focus of Marxist and critical theory that has also influenced the analysis of environmental policy formation. Ownership and control of the media play an important role in the formation of public opinion on environmental issues. Other meta-policy research relevant to the development of environmental policy focuses on institutional and systemic factors. For instance, the role of environmental institutions and their capacity and power within the broader systems of government is found to be an important factor in advancing or constraining environmental policy. More broadly, the question of whether capitalism is compatible or not with long-term environmental protection has been a subject of debate. As, after the collapse of the Soviet Union and the introduction of capitalism in China, capitalism became a globally dominant system, this question has become even more important to the future development of environmental policy at the national and international levels. As many analysts of global environmental politics have pointed out, the institutions for developing effective environmental policy at that level are weak and rather ineffective, as demonstrated by accounts of continuing environmental deterioration. == Democratic challenges ==
