“But there are limits to how responsibly companies can behave when behaving responsibly raises their costs and consumers are unwilling to pay higher prices. The most important constraint on the pursuit of virtue is the market”

David Vogel, Professor. Haas School of Business, University of California, Berkeley and author of The Market for Virtue: The Potential and Limits of Corporate Social Responsibility

Strategies for handling environmental compliance

Strategies for Handling Environmental Compliance

  • Prevention

  • Treatment for Reuse or Release

  • Release to the Environment

  • Storage

Prevention avoids the problem of pollutants

Prevention(avoids the problem of pollutants)

  • Goes hand-in hand with cost reduction

    • Fuel efficiency

    • Lower Wastewater Generation

  • Can take large capital investment

    • Steam pulp dryer

    • Dry beet handling

Treatment for reuse or release removes or reduces pollutants to acceptable levels

Treatment for Reuse or Release (Removes or reduces pollutants to acceptable levels)

  • Treatment for Reuse

    • wastewater

    • waste lime

  • Treatment for Release

    • Stack Gasses

    • wastewater

  • Treatment systems often generate their own wastes

    • dust (particle removal)

    • sludge (wastewater treatment)

Release into environment

Release into Environment

  • Limited Capacity to accept Pollutants

  • Highly Regulated

  • Carefully Monitored

Almost all discharges are regulated

Almost all Discharges Are Regulated

  • EPA

  • State Department of Health

  • Tribal Environmental Council

  • County Board

  • City Council

Penalties for not obeying environmental rules

Penalties for not Obeying Environmental Rules

  • Civil and Criminal

  • Fines

  • Jail

  • Disqualification

  • Escalating

Discharging to the environment is costly

Discharging to the Environment is Costly

  • Large Amount of Material

  • Compliance Costs

    • Permitting

    • Pre-discharge costs

    • Discharge monitoring

    • Post-discharge costs

  • Fines if there are problems

Temporary and permanent storage staging areas landfills and ponds

Temporary and Permanent Storage (Staging Areas, Landfills and Ponds)

  • Ownership and Operations

  • Permitting

  • Ongoing Care

  • Liability

Strategy for environmental protection must balance many issues

Strategy for Environmental Protection must Balance many Issues

  • Balance Costs and Benefits

  • Should fit into larger corporate strategy

  • Should consider outside stakeholders

  • Should consider short- and long-term consequences

Environmental stewardship is the right thing

Environmental Stewardship is the Right Thing

  • Protects Nature

  • Good Neighbor

  • Reduces Expenses (can make money)

  • Prevents Trouble

  • Part of the Job
