Last week McKinsey & Company released a report, Reducing U.S.
Greenhouse Gas Emissions: How Much at What
Cost?,
that found that the goals of current greenhouse gas emissions reduction
legislation for 2030 are achievable with current technology and at
manageable cost, although it warned:
Achieving these reductions at the lowest cost to the economy, however,
will require strong, coordinated, economy-wide action that begins in
the near future.
The report was commissioned by the environmental organizations
Environmental Defense and National Resources Defense Council and the
energy technology companies Honeywell, National Grid, PG&E Corporation,
Shell, and DTE Energy. The Conference
Board, the leading U.S. corporate
think tank, endorsed the paper.
McKinsey found that a broad mix of abatement options need to be
followed; no one strategy accounted for more than 11% of the total
abatement, noting:
In regions with high-carbon grids, energy efficiency improvements,
typically through upgrades to building standards,
HVAC equipment, and appliances, are likely
to be the most effective and lowest-cost strategies. Conversely,
sectors and regions with access to low-carbon grid infrastructure
offer more compelling applications of such emerging technologies as
PHEVs (plug-in hybrid vehicles).
In its conclusion the report reiterated the importance of immediately
implementing energy efficiency strategies, many of which end up saving
more money than they cost, to “buy time” for emerging technologies to
develop commercially.
