#Study finds piece-by-piece approach to emissions policies can be effective Discussions on curbing climate change tend to focus on comprehensive, emissions-focused measures:
or a tax on all carbon emissions. But a new study by researchers at MIT finds that a egmentalapproach involving separate targeting of energy choices
and energy consumption through regulations or incentives can play an important role in achieving emission reductions. The new study, by assistant professor of engineering systems Jessika Trancik, is being published this week in the journal Environmental science and Technology.
Trancik is joined on the paper by three MIT graduate students: Michael Chang and Christina Karapataki of the Engineering Systems Division and Leah Stokes of the Department of Urban Studies and Planning. policy that focused on controlling carbon emissions is a different kind of policy than one that focused
on the underlying demand-side and supply-side technology drivers, Trancik says. And while those calling for sweeping, emission-focused policies have faced often uphill battles in regions, states,
in order to meet emissions reduction commitments that have been made by most nations. any nations are generally moving in the direction of segmental policies,
hat would involve capping carbon dioxide emissions, but then using these segmental policies to address particular areas of concern,
A global agreement on carbon emissions would be most effective at reducing the risks of climate change
An added benefit, Trancik notes, is that discussing segmental approaches is likely to lead to a greater understanding of where emissions reductions might come from,
which may eventually make it easier to reach an agreement on limiting carbon emissions directly. Decisions made over the next decade will have long-lasting effects on overall emissions,
says this study valuates a number of examples of policies that contribute to a portfolio effort of reducing greenhouse gas emissions,

They play a complex role in the atmosphere and in any potential climate change scenario. But rudimentary data has simplified their role in simulations leading to variability among climate models.
