Environmental policies could have positive impact on businesses

Business around the world claim that environmental policies hurt businesses, but a new study has found that’s not the case.

A pair of Cornell economists carried out an analysis wherein they found that¬†market-based or incentive-based policies may actually benefit regulated firms in the traditional and “green” energy sectors, by spurring innovation and improvements in production processes. Policies that mandate environmental standards and technologies, on the other hand, may broadly harm output and profits.

For the analysis scientists mined Chinese provincial government websites and other online sources to compile a comprehensive data set of nearly 2,700 environmental laws and regulations in effect in at least one of 30 provinces between 2002 and 2013. This period came just before China declared a “war on pollution,” instituting major regulatory changes that shifted its longtime prioritization of economic growth over environmental concerns.

The researchers categorized each policy as one of four types: “command and control,” such as mandates to use a portion of electricity from renewable sources; financial incentives, including taxes, subsidies and loans; monetary awards for cutting pollution or improving efficiency and technology; and nonmonetary awards, such as public recognition.

They assessed how each type of policy impacted China’s gross domestic product, industrial output in traditional energy industries and the profits of new energy sector companies, using publicly available data on economic indicators and publicly traded companies.

Command and control policies and nonmonetary award policies had significant negative effects on GDP, output and profits, Si and Lin Lawell concluded. But a financial incentive – loans for increasing renewable energy consumption – improved industrial output in the petroleum and nuclear energy industries, and monetary awards for reducing pollution boosted new energy sector profits.

That finding, they said, is consistent with the “Porter hypothesis” – Harvard Business School Professor Michael Porter’s 1991 proposal that environmental policies could stimulate growth and development, by spurring technology and business innovation to reduce both pollution and costs.

While certain policies benefitted regulated firms and industries, the study found that those benefits came at a cost to other sectors and to the overall economy. Nevertheless, Si and Lin Lawell said, these costs should be weighed against the benefits of these policies to the environment and society, and to the regulated firms and industries.

Economists generally prefer market-based or incentive-based environmental policies, Lin Lawell said, with a carbon tax or tradeable permit system representing the gold standard. The new study provides more support for those types of policies.
