行业团体警告说，随着经济努力恢复其基础的努力，一场席卷而新近的马萨诸塞州气候变化法案可能会破坏开发项目，并阻止建设。新利18备用网址

NAIOP Massachusetts, which represents major commercial and residential developers, says the goals of the bill, which would slash emissions by 50% of 1990 levels by end of this decade, are laudable. The NextGen Roadmap bill even won praise from one of state’s largest business groups, Associated Industries of Massachusetts, as well as from environmental organizations.

马萨诸塞州NAIOP的政府事务助理Anastasia Nicolaou说：“总的来说，当做出这些承诺时，我们感到非常振奋。”

但是，马萨诸塞州的NAIOP以及大波士顿房地产委员会，两组代表主要开发商以及与他们合作的许多公司，他们表示对他们辩称的法案中的特定规定有重大保留新利18备用官网登录成本并使发展成本高昂和困难。

In particular, a provision in the newly passed NextGen Roadmap bill would enable individual cities, towns and suburbs to mandate tough, net-zero-energy building codes could hurt construction and development at a time when the economy remains shaky, they say.

之所以需要规则，是因为“今年批准的项目和建筑物批准在2050新利18备用网址年，马萨诸塞州的整个经济在各个方面都必须提出“净零”排放，”. Mike Barrett and Rep. Thomas Golden, both Democrats and the chairs of the Legislature’s climate change committee, in a statement. “So we give the force of law to the creation of a 'net zero stretch energy code'."

然而，对于开发人员而言，在新办公室或其他商业建筑中实现零排放是“很少可以实现的”，尤其是在涉及到10层以上的结构时，马萨诸塞州Naiop的Nicolaou认为。

While some legislators have argued that a wave of new solar-power construction could help make net-zero a reality, Nicolaou is skeptical there is currently enough clean energy to fulfill demand.

她说：“减少碳越来越重要 - 我们只需要确保以实用和可行的方式到达那里。”

The goal could drive up construction and maintenance costs, seriously undermining the feasibility of large-scale commercial or residential projects.

“Net zero increases the cost of construction … current rents would not be able to cover the increases,” Nicolaou said. “It could have the effect of driving our innovation economy right out of the state.”

Meanwhile, the relatively broad and ambiguous wording of the net-zero energy provision also has the potential to cast a large degree of uncertainty over development projects currently under review by local officials, or getting ready to start the review process, Nicolaou said.

The bill leaves it up to the state Dept. of Energy Resources to develop the new, net-zero energy stretch code, which could then be adopted by individual communities.

But as it stands now, there is no definition yet of what net-zero energy will mean in practical terms, or to what types of buildings it would apply to.

And while the tough new energy code would not go into effect unless it is adopted by various cities and towns, officials in Boston, Somerville and Cambridge, where the lion’s share of construction in Eastern Massachusetts takes place, wrote letters of support for the new legislation, Nicolaou said.

“Any project currently being planned or designed anywhere in Massachusetts will have to seriously consider moving forward without knowing what requirements will be in place,” she said.

Greg Vasil, president and CEO of the Greater Boston Real Estate Board, expressed similar concerns.

There will be an impact with process and there certainly will be an impact with costs,” Vasil said. “Everyone recognizes the need to do something with climate change,” Vasil said, calling it a “balancing act.”

超出国家建筑法规并实施零净要求的当地社区可能会迫使一些开发人员计划建立更多负担得起的劳动力住房，而是专注于奢侈品。

A project, for example that previously would have cost $400 to $500 a square foot to build, might cost $525 a square foot.

“These codes can be onerous and can really drive up costs,” Vasil said.

Gov. Charlie Baker (R) released his own plan this week that would cut emissions by a sizable but slightly smaller 45% over the same time period.

Officials in Baker’s office have said the governor is reviewing the climate change bill passed by the state’s Democratic-controlled legislature, and have not indicated either way whether he will sign it.

Meanwhile, both development and real estate groups said they will also be keeping a close eye on new rules proposed by Boston officials to deal with another facet of climate change— more frequent flooding as sea level rise.

The Boston Planning and Development Agency is pushing a plan for an overlay zoning district that could cover parts of the city that are increasingly prone to flooding.

New projects bigger than 20,000 sq ft, in turn, would have to go through an additional step in the city review process, one that would require developers to make design changes or take other measures to deal with potential flooding.

瓦西尔说：“这是可以理解的，为什么要进行审查。”“真正的收获是它实际上是如何运作，以及如何影响建筑成本以及他们的市场将承担的责任，而在这些成本方面没有忍受。”新利18备用官网登录

Lawmakers also sent a $16.5 billion transportation bond bill to Baker's desk. The bill authorizes billions of dollars in bonds for highway and bridge maintenance, train modernization, and major capital projects such as an MBTA红线蓝线连接器and the extension of commuter rail service to the South Coast. It also funds the approaches to the two鳕鱼角桥.
