Kurt’s foremost role is to help create and implement policies that encourage land conservation and development that is consistent with the MA Sustainable Development Principles.  As Co-Chair of the GWSA Transportation and Land Use Subcommittee he is currently focused on implementation of the "Smart Growth Policy Package" and other Clean Energy & Climate Plan policies. 

He also manages the Gateway City Parks Program that creates & restores parks in the 26 Gateway Cities, serves as liaison to the Executive Office of Housing & Economic Development and MassDOT regarding land use policies, helps the Green Communities Division review applications and develop model energy zoning regulations, and administers EEA’s Grants and Technical Assistance Office.

He was originally hired as an intern to help implement E.O. 385 – “Planning for Growth”.  He next worked on the Community Preservation Initiative responsible for Buildout Analyses for all MA communities, E.O. 418 and the creation of 225 municipal Community Development Plans, and the Smart Growth Technical Assistance Grant Program.  Under the leadership of the Office for Commonwealth Development Kurt helped draft the MA Sustainable Development Principles and create and implement the Commonwealth Capital Policy and the Smart Growth/Smart Energy Toolkit.

Subcommittee Summary: Transportation is second only to buildings in responsibility for GHG emissions in Massachusetts. Improving vehicle efficiency, lowering the carbon content of fuel, and reducing vehicle miles traveled are the three main strategies being pursued to lower emissions from this sector and achieve the reductions required by the Global Warming Solution Act. The Clean Energy and Climate Plan anticipates that the following seven transportation and land use policies that the Subcommittee is implementing can collectively reduce greenhouse gas emissions 7.6%: Federal and California Vehicle Efficiency and GHG Standards, Federal emissions and Fuel Efficiency Standards for Medium and Heavy Duty Vehicles, Federal Renewable Fuel Standard and Low Carbon Fuel Standard, Clean Car Consumer Incentives, Pay as You Drive (PAYD) Auto Insurance, GreenDOT, and the Smart Growth Policy Package.

She has worked on quantifying aspects of energy air emissions since the adoption of NOx emissions trading programs in the Northeast in the 1990s. She has focused on controlling mercury emissions from coal-fired power plants, monitoring of low level emissions from power plants and measuring power plant output as the foundation for output-based regulations. Sharon has an MS in Environmental Engineering and Policy from Tufts University and a BS in Materials Science and Engineering from the Massachusetts Institute of Technology.

Subcommittee Summary: Greenhouse gas emissions from activities not related to energy use represent a small but important part of statewide GHG emissions. Although these sources historically represent on the order of 7 percent of total emissions, many of the gases emitted by these processes have a high global warming potential (GWP), thousands of times greater than CO2. Furthermore, projections of future emissions show steady growth in industrial emissions while emissions from most energy related sectors, with the exception of transportation, are projected to level off or even decline. Specific industrial processes that emit significant quantities of GHGs in Massachusetts include: leakage of refrigerant chemicals from commercial equipment and motor vehicle air conditioners, leakage of SF6 from electric power transmission and distribution, and combustion of plastics in solid waste incinerators. This subcommittee will work to reduce emissions from non-energy sources through some of the following policies: Reducing GHG Emissions from Motor Vehicle Air Conditioning, Stationary Equipment Refrigerant Management, Reducing SF6 Emissions from Gas-Insulated Switchgear, and Reducing GHG Emissions from Plastics.
